Surge tolerance increased by built-in Zener and stable high avalanche tolerance achieved!
The "INKE series" features a built-in Zener diode connected between the drain and source, which protects the MOSFET from back electromotive force during motor and solenoid drive operations. By incorporating a Zener diode with a reverse breakdown voltage lower than that of the built-in MOSFET, the Zener diode will break down first when overcurrent/voltage is applied to the drain, thereby protecting the built-in MOSFET. The avalanche and surge ratings between the drain and source have been significantly improved, eliminating the need for a freewheeling diode for back electromotive force recovery. 【Features】 ■ Built-in Zener diode with a reverse breakdown voltage lower than that of the built-in MOSFET ■ The Zener diode breaks down first when overcurrent/voltage is applied to the drain, protecting the built-in MOSFET ■ Significant improvement in avalanche and surge ratings between the drain and source ■ No need for a freewheeling diode for back electromotive force recovery *For more details, please refer to the PDF document or feel free to contact us.

Company information
Isahaya Electronics began production of small signal transistors in 1973 and has evolved its semiconductor technology into design technologies for gate drivers and DC/DC converters. In recent years, the company has also focused on developing high-efficiency, high-power-factor power supply technologies to contribute to carbon neutrality. (Three-phase PFC, 1500V input compatible DC/DC converters, bidirectional converters, etc.) Meanwhile, to meet diverse needs, small signal transistors have also evolved with enhanced functionality and integration, expanding the lineup of high-voltage, high-current transistors, MOSFETs, and analog ICs.
