SiRA20DP N-Channel 25V MOSFET Vishay SiRA20DP N-Channel 25V MOSFET features an optimized total gate charge (Qg), gate-drain charge (Qgd), and Qgd/gate-source charge (Qgs) ratio that reduces switching-related power loss. This TrenchFET® Gen IV device is 100% Rg and UIS tested. Typical applications for Vishay SiRA20DP N-Channel 25V MOSFET include synchronous rectification, high power density DC/DC, synchronous buck converter, OR-ing, load switching, and battery management.
