SGSF324
HIGH VOLTAGE FASTSWITCHING NPN
POWER TRANSISTOR
s SGS-THOMSON PREFERRED SALESTYPE
s NPN TRANSISTOR
s HIGH VOLTAGE CAPABILITY
s VERY HIGH SWITCHING SPEED

APPLICATIONS:
s SWITCH MODE POWER SUPPLIES

DESCRIPTION 3
The SGSF324 is manufactured using 2
1
Multiepitaxial Mesa technology for cost-effective
high performance and uses a Hollow Emitter
structure to enhance switching speeds. TO-220
The SGSF series is designed for high speed
switching applications such as power supplies
and horizontal deflection circuits in TVs and
monitors.
