Vishay – New 80V MOSFET in PowerPAK® SO-8
SiR680ADP Offers Best in Class RDS(ON) Times Gate Charge FOM to Increase Efficiency; Combines RDS(ON) Down to 2.35 mOhm With 55 nC Gate Charge and COSS of 614 pF
The News
Vishay Intertechnology introduces a new 80 V TrenchFET® Gen IV n-channel power MOSFET in the 6.15 mm by 5.15 mm PowerPAK® SO-8 single package that offers best in class on-resistance times gate charge — a key figure of merit (FOM) for MOSFET’s used in power conversion applications — of 129 mOhm*nC. 
- The MOSFET’s on-resistance times gate charge FOM is 12.2 % lower than the closest competing product and 22.5 % lower than the previous-generation device, making it the most efficient solution available for typical 48 V input to 12 V output DC/DC converters.
- The device’s specifications are fine-tuned to reduce the power losses from switching, channel conduction, and diode conduction, resulting in increased efficiency.
- In selected applications, power saving could be as high as 1 W average across the load.
The Key Specifications:
- Drain-source voltage: 80 V
- Typical on-resistance:
- At 10 V: 2.35 mΩ
- At 7.5 V: 2.70 mΩ
- Gate charge: 55 nC at 10 V and 43 nC at 7.5 V
- Output charge: 95 nC
- COSS: 614 pF
- Package: PowerPAK® SO-8
