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.
QUICK REFERENCE DATA
PINNING - SOT429
LIMITING VALUES
Limiting values in accordance with the Absolute Maximum Rating System (IEC 134)
THERMAL RESISTANCES
1 Turn-off current.
