Philips Semiconductors Objective specification Silicon Diffused Power Transistor BU4550AL GENERAL DESCRIPTION Enhanced performance, new generation, high-voltage, high-speed switching npn transistor in a plastic full pack envelope intended for use in horizontal deflection circuits of colour television receivers and p.c monitors. Features exceptional tolerance to base drive and collector current load variations resulting in a very low worst case dissipation.

January 1998 3 Rev 1.000 Philips Semiconductors Objective specification Silicon Diffused Power Transistor BU4550AL DEFINITIONS Data sheet status Objective specification Product specification Limiting values Limiting values are given in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of this specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. (c) Philips Electronics N.V. 1998 All rights are reserved.
