Infineon Technologies IPT60T022S7XTMA1

Overview

IPT60T022S7XTMA1 from Infineon is a 600 V, 22 mΩ silicon carbide–free superjunction MOSFET with integrated temperature sensor, designed for static switching and high-current line rectification in industrial SMPS, UPS, and solar inverters. It delivers 23 A continuous drain current at T_C = 140°C, 371 A pulsed current, and features a 0.32 °C/W junction-to-case thermal resistance in PG-HSOF-8 package with exposed drain tab.

For engineers reviewing the IPT60T022S7XTMA1 datasheet, IPT60T022S7XTMA1 pinout, IPT60T022S7XTMA1 application, or IPT60T022S7XTMA1 equivalent, key selection criteria include R_DS(on) stability over temperature, integrated junction temperature sensing accuracy (±5.96 mV/K TC), low gate charge (150 nC), and robust dv/dt ruggedness (20 V/ns) for high-reliability solid-state relay and circuit breaker designs.

Technical Context

This CoolMOS™ S7 device uses charge-compensation superjunction architecture to achieve ultra-low R_DS(on) while maintaining 600 V blocking capability and enhanced avalanche energy rating (286 mJ). Its internal body diode exhibits 0.82 V forward voltage and 460 ns reverse recovery time at 23 A.

The monolithically integrated temperature sensor is electrically isolated from the power die and provides calibrated forward-voltage-based junction temperature measurement across –55°C to +175°C, with 10 µA to 500 µA bias current options and <±0.1 V absolute error over full range.

FAQ

What is the function of Pin 2 on IPT60T022S7XTMA1?

Pin 2 is the anode of a monolithically integrated silicon diode used for junction temperature sensing. It must be biased with a constant current source (10–500 µA) between Pin 2 (anode) and Pin 1 (source/cathode reference); its forward voltage varies linearly with temperature at ~5.96 mV/K, enabling accurate real-time thermal monitoring without external sensors.

Can IPT60T022S7XTMA1 replace standard 600 V MOSFETs in existing PCB layouts?

Yes, but only if the PCB footprint matches PG-HSOF-8: 8-pin gull-wing with 0.65 mm pitch and exposed drain tab requiring ≥20 mm² copper area. The pinout differs from SO-8 or TO-220-Pin 1 is Source (not Gate), and Pin 2 is dedicated to temperature sensing, so schematic and layout revisions are required for functional integration.

How does the integrated temperature sensor improve system reliability?

The sensor provides direct, drift-free junction temperature measurement with ±0.1 V accuracy over –55°C to +175°C, enabling real-time thermal derating, predictive shutdown before T_j exceeds 150°C, and elimination of calibration drift seen in external NTCs-critical for sealed industrial enclosures where ambient temperature cannot represent actual die temperature.

What is the maximum safe operating frequency for IPT60T022S7XTMA1?

IPT60T022S7XTMA1 is optimized for low-frequency switching (≤100 kHz), not RF or MHz-range operation. Its 150 nC total gate charge and 150 ns turn-off delay make it inefficient above 50–100 kHz; using it beyond this range increases switching losses disproportionately and risks thermal runaway without aggressive gate drive and cooling.
