N-Channel 250 V (D-S) MOSFET
FEATURES
• PWM-optimized TrenchFET
®
power MOSFET
• 100 % R
g
tested
•Avalanche tested
• Material categorization:
for definitions of compliance please see
www.vishay.com/doc?99912
APPLICATIONS
• Primary side switch in:
- Telecom power supplies
- Distributed power architectures
- Miniature power modules
Notes
a. Surface mounted on 1" x 1" FR4 board
b. See solder profile (www.vishay.com/doc?73257). The PowerP
AK SO-8 is a leadless package. The end of the lead terminal is exposed
copper (not plated) as a result of the singulation process in manufacturing. A solder fillet at the exposed copper tip cannot be guaranteed
and is not required to ensure adequate bottom side solder interconnection
c. Rework conditions: manual soldering with a soldering iron is not recommended for leadless components
