The 45 V Sweet Spot for Higher Efficiency Synchronous Rectification

Designers of power conversion circuitry are often forced by certain transient conditions to specify a 60 V power MOSFET in synchronous rectification applications where a 40 V MOSFET would deliver significantly better efficiency. The 45 V TrenchFET Gen IV MOSFETs reach a sweet spot between performance FOMs and safety margin. Their 45 V breakdown voltage means a 12.5 % greater safety margin than 40 V rated MOSFETs with similar on-resistance characteristics.
