Infineon - TRENCHSTOP™ Feature IGBT - Protected Series for Induction Heating

Infineon – TRENCHSTOP™ Feature IGBT – Protected Series for Induction Heating

The Protected IGBT is the first device in the new family of TRENCHSTOP™ feature IGBTs, which add new functionality to standard discrete IGBTs.

The innovative TRENCHSTOP™ Feature IGBT Protected Series combines a 20 A 1350 V IGBT in RC-H5 technology with a unique protecting gate driver IC together in a TO-247 6-pin package.
The Protected IGBT features not only the industry’s best IGBT performance considering blocking voltage, static losses and conduction losses in soft switching application but also integrated protection functions.

Features
Reverse conducting IGBT with
– monolithic body diode designed for soft commutation

Integrated driver with
– Overvoltage and overcurrent protection
– Active clamp control circuit
– Programmable overvoltage threshold
– Programmable cycle-by-cycle overcurrent threshold
– Integrated gate drive with 2 level turn-on current
