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.
