Vishay Intertechnology has expanded its portfolio of N-channel power MOSFETs, introducing the 650V EF series devices to provide greater voltage headroom when compared to the existing 600V E series MOSFETs.

Benefitting from the super-junction MOSFET technology on which the E series MOSFETs are based, the 650V EF devices offer a ten times lower reverse-recovery charge than standard MOSFETs. This enables them to regain the ability to block the full breakdown voltage more quickly, helping to avoid failure from shoot- through and thermal over-stress.

The new EF MOSFETs, which include a fast body diode, may be used in advanced power circuit designs: they are particularly well suited to Zero-Voltage Switching (ZVS) and soft- switching topologies such as phase-shifted bridges and LLC converter half-bridges.

Their ultra-low on-resistance and gate charge result in extremely low conduction and switching losses, helping users to save energy in high-power, high-performance switch-mode applications.
