100-150V rated PowerTrench MOSFET from Fairchild in industrial-type packages

Fairchild Semiconductor has expanded its PowerTrench MOSFET family of 100 and 150V devices to include industrial-type packages, including the TO-220, D2PAK, TO247, I2PAK, TO220 Full Pack and D2PAK-7L.

Fairchild says these devices are optimized power switches that combine a small gate charge (QG), a small reverse recovery charge (Qrr) and a soft reverse recovery body diode, which allows for fast switching for synchronous rectification in AC-DC power supplies.

These devices employ a shielded-gate structure that provides charge balance. By using this technology, the figure of merit (QG x RDS(ON)) is 66 percent lower than previous solutions, providing designers a high efficiency solution for applications including synchronous rectification, micro-solar inverters and off line UPS systems and PDU/BFU in telecom power distribution, according to Fairchild.

A low reverse recovery charge and the soft reverse recovery body diode reduces voltage spikes or oscillation in the system, eliminating the snubber circuit - or replacing a higher voltage rating MOSFET - enhancing efficiency and reducing the design bill of materials.

The first devices available in the industrial-type packages include the FDP083N15A_F102, FDB082N15A and FDP036N10A N-channel PowerTrench MOSFETs.
