SiC paralleling has never been a question of whether it should be done. In the era of high power, it is a must-answer question.

Traditional IGBTs with high gate voltage losses carry the risk of short-circuit! Firstack 1FHD0440 features revolutionary driver technology that eliminates the risks associated with high gate voltage,...

Look forward to seeing you at PCIM Europe 2026 Hall 7-175!

Firstack’s new SiC single‑channel driver, 2FHD0225, directly addresses these challenges.

We are honored to be awarded the “Outstanding Partner” by Sungrow at SGPC’2026.

In IGBT applications, gate oscillation is one of the most common challenges. It not only affects switching performance but can also trigger overvoltage, overheating, or even device damage.

Firstack possesses over a decade of application experience in optical module-based IGBT driver products, with cumulative shipments exceeding 200,000 units.

Circulating currents during SiC parallel operation

The commonly available board-level driver cores typically integrate four components: Power supply, Isolation(power + signal), Driver, Protection. What remains to be addressed before full deployment?
