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 - SOT399
LIMITING VALUES
Limiting values in accordance with the Absolute Maximum Rating System (IEC 134)
THERMAL RESISTANCES
1 Turn-off current.
