Silicon Diffused Power Transistor
BU2708AF
GENERAL DESCRIPTION
High voltage, high speed switching npn transistor in a plastic full-pack envelope. Intended for use in horizontal
deflection circuits of colour television receivers. Features exceptional tolerance to base drive and collector current
load variations, resulting in a low worst-case dissipation. Designed to withstand V
deflection circuits of colour television receivers. Features exceptional tolerance to base drive and collector current
load variations, resulting in a low worst-case dissipation. Designed to withstand V
CES
pulses up to 1700 V.
