iDEAL Semiconductor iS20M028S1PQ SuperQ™ 200V N-Channel Automotive Power MOSFET

Introduction

The iS20M028S1PQ from iDEAL Semiconductor is a 200 V N-channel power MOSFET intended for high-efficiency automotive and industrial power-switching designs. Built on the company’s SuperQ™ technology, it combines low conduction resistance with reduced switching losses in a durable TO-220 package.

Part Description

The iS20M028S1PQ is an AEC-Q101-qualified automotive power MOSFET with a 200 V drain-to-source voltage rating. Its N-channel design supports efficient high-side or low-side switching arrangements when paired with an appropriate gate-drive circuit.

A maximum drain-to-source on-resistance of 25 mΩ helps reduce conduction losses when the device is fully enhanced. The MOSFET is also designed to provide low switching losses, making it suitable for applications that operate at elevated switching frequencies or require strong overall power-conversion efficiency.
