Features
miniBLOC package
- Electrically isolated copper base
- Low coupling capacitance to the heatsink for
reduced EMI
- International standard package SOT-227
- Easy screw assembly
fast CoolMOS power MOSFET - 3
rd
generation
- High blocking capability
- Low on resistance
- Avalanche rated for unclamped
inductive switching (UIS)
- Low thermal resistance
due to reduced chip thickness
Enhanced total power density
Applications
Switched mode power supplies (SMPS)
Uninterruptible power supplies (UPS)
Power factor correction (PFC)
Welding
Inductive heating
G = Gate
D = Drain
