## Description

The SiR680ADP is a high-performance N-channel 80 V power MOSFET from Vishay Siliconix in a PowerPAK SO-8 single package. Built on Vishay's TrenchFET Gen IV technology, it is optimized for the lowest RDS(on) x Qg and RDS(on) x Qoss figures of merit (FOM), making it ideal for synchronous rectification, primary-side switching, and DC-DC converter applications. The device delivers extremely low on-resistance (2.35 mOhm typical at VGS = 10 V) with a continuous drain current rating of 100 A at 25 C.
