general data e 500 mw do-35 glass motorola tvs/zener device data 6-98 500 mw do-35 glass data sheet application note e zener voltage since the actual voltage available from a given zener diode is temperature dependent, it is necessary to determine junc- tion temperature under any set of operating conditions in order to calculate its value. the following procedure is recom- mended: lead temperature, t l , should be determined from: t l = q la p d + t a . q la is the lead-to-ambient thermal resistance ( c/w) and p d is the power dissipation. the value for q la will vary and depends on the device mounting method. q la is generally 30 to 40 c/w for the various clips and tie points in common use and for printed circuit board wiring. the temperature of the lead can also be measured using a thermocouple placed on the lead as close as possible to the tie point. the thermal mass connected to the tie point is normally large enough so that it will not significantly respond to heat surges generated in the diode as a result of pulsed operation once steady-state conditions are achieved. using the mea- sured value of t l , the junction temperature may be deter- mined by: t j = t l + d t jl . d t jl is the increase in junction temperature above the lead temperature and may be found from figure 2 for dc power: d t jl = q jl p d . for worst-case design, using expected limits of i z , limits of p d and the extremes of t j ( d t j ) may be estimated. changes in voltage, v z , can then be found from: d v = q vz t j . q vz , the zener voltage temperature coefficient, is found from figures 4 and 5. under high power-pulse operation, the zener voltage will vary with time and may also be affected significantly by the zener resistance. for best regulation, keep current excursions as low as possible. surge limitations are given in figure 7. they are lower than would be expected by considering only junction temperature, as current crowding effects cause temperatures to be ex- tremely high in small spots, resulting in device degradation should the limits of figure 7 be exceeded. ll 500 400 300 200 100 0 0 0.2 0.4 0.6 0.8 1 2.460 v 62200 v l, lead length to heat sink (inch)

data 6-118 500 mw do-35 glass data sheet application note since the actual voltage available from a given zener diode is temperature dependent, it is necessary to determine junc- tion temperature under any set of operating conditions in order to calculate its value. the following procedure is recom- mended: lead temperature, t l , should be determined from: t l = q la p d + t a . q la is the lead-to-ambient thermal resistance ( c/w) and p d is the power dissipation. the value for q la will vary and depends on the device mounting method. q la is generally 30 to 40 c/w for the various clips and tie points in common use and for printed circuit board wiring. the temperature of the lead can also be measured using a thermocouple placed on the lead as close as possible to the tie point. the thermal mass connected to the tie point is normally large enough so that it will not significantly respond to heat surges generated in the diode as a result of pulsed operation once steady-state conditions are achieved. using the mea- sured value of t l , the junction temperature may be deter- mined by: t j = t l + d t jl . d t jl is the increase in junction temperature above the lead temperature and may be found as follows: d t jl = q jl p d . q jl may be determined from figure 3 for dc power condi- tions. for worst-case design, using expected limits of i z , limits of p d and the extremes of t j ( d t j ) may be estimated. changes in voltage, v z , can then be found from: d v = q vz d t j . q vz , the zener voltage temperature coefficient, is found from figure 2. under high power-pulse operation, the zener voltage will vary with time and may also be affected significantly by the zener resistance. for best regulation, keep current excursions as low as possible. surge limitations are given in figure 5. they are lower than would be expected by considering only junction temperature, as current crowding effects cause temperatures to be ex- tremely high in small spots, resulting in device degradation should the limits of figure 5 be exceeded. general data e 500 mw do-35 glass motorola tvs/zener device data 6-119 500 mw do-35 glass data sheet *electrical

actual voltage available from a given zener diode is temperature dependent, it is necessary to determine junc- tion temperature under any set of operating conditions in order to calculate its value. the following procedure is recom- mended: lead temperature, t l , should be determined from: t l = q la p d + t a q la is the lead-to-ambient thermal resistance ( c/w) and p d is the power dissipation. the value for q la will vary and depends on the device mounting method. q la is generally 3040 c/w for the various clips and tie points in common use and for printed circuit board wiring. the temperature of the lead can also be measured using a thermocouple placed on the lead as close as possible to the tie point. the thermal mass connected to the tie point is normally large enough so that it will not significantly respond to heat surges generated in the diode as a result of pulsed operation once steady-state conditions are achieved. using the mea- sured value of t l , the junction temperature may be deter- mined by: t j = t l + d t jl d t jl is the increase in junction temperature above the lead temperature and may be found from figure 2 for a train of power pulses (l = 3/8 inch) or from figure 10 for dc power. d t jl = q jl p d for worst-case design, using expected limits of i z , limits of p d and the extremes of t j ( d t j ) may be estimated. changes in voltage, v z , can then be found from: d v = q vz d t j q vz , the zener voltage temperature coefficient, is found from figures 5 and 6. under high power-pulse operation, the zener voltage will vary with time and may also be affected significantly by the zener resistance. for best regulation, keep current excursions as low as possible. data of figure 2 should not be used to compute surge capa- bility. surge limitations are given in figure 3. they are lower than would be expected by considering only junction tempera- ture, as current crowding effects cause temperatures to be ex- tremely high in small spots resulting in device degradation should the limits of figure 3 be exceeded. general data e 500 mw do-35 glass motorola tvs/zener device data 6-125 500 mw do-35 glass data sheet figure 5. units to
