Infineon Technologies IPDQ60T017S7AXTMA1

Overview

IPDQ60T017S7AXTMA1 from Infineon is a 600 V, 17 mΩ CoolMOS™ S7TA superjunction MOSFET with integrated temperature sensor (TS), optimized for static switching and high-current low-frequency applications such as HV eFuse and on-board charger disconnect switches. It delivers 488 A pulsed drain current, features 0.25 °C/W junction-to-case thermal resistance, and supports AEC-Q101 qualification for automotive-grade reliability.

For engineers reviewing the IPDQ60T017S7AXTMA1 datasheet, IPDQ60T017S7AXTMA1 pinout, IPDQ60T017S7AXTMA1 application, or IPDQ60T017S7AXTMA1 equivalent, key selection criteria include R_DS(on) stability over temperature, embedded junction temperature sensing accuracy, gate charge profile for driver sizing, and PG-HDSOP-22 package thermal performance in high-power DC switching layouts.

Technical Context

This device implements Infineon's 7th-generation CoolMOS™ SJ technology with monolithically integrated silicon diode and precision temperature-sensing p-n junction. The TS pin (Pin 3) provides forward-voltage-based junction temperature measurement with ±5.96 mV/K coefficient and <±0.1 V error across –40°C to 175°C.

It operates as a unidirectional high-side or low-side switch with body diode conduction capability (V_SD = 0.82 V at 29 A), rated for 375 mJ single-pulse avalanche energy and 20 V/ns dv/dt ruggedness-enabling robust operation in high-voltage DC bus protection circuits without external snubbers.

Key Specifications

Pinout & Package

IPDQ60T017S7AXTMA1 uses the PG-HDSOP-22 surface-mount package with exposed thermal tab (Drain-connected) for low-inductance, high-current PCB mounting. The 22-pin layout integrates power, gate, source, and diagnostic terminals in a compact 15.8 × 10.2 mm footprint.

FAQ

Can IPDQ60T017S7AXTMA1 be used in parallel configurations?

Yes, but strict layout rules apply: gate resistors must be placed on the Driver Source (Pin 4), not Gate, to minimize loop inductance and ensure balanced current sharing. Source pins (5–11) must be symmetrically routed, and thermal coupling between devices must be uniform to avoid thermal runaway. Parallel operation beyond two units requires individual TS monitoring per device.

What is the maximum allowable continuous drain current at 100°C case temperature?

At T_C = 100°C, the device supports 65 A continuous drain current (ID) based on its 500 W P_tot rating and 0.25 °C/W R_thJC. This assumes adequate heatsinking and derating per Figure 1 in the datasheet; exceeding this requires active cooling or reduced duty cycle to maintain T_j ≤ 150°C.

How does the temperature sensor interface electrically with a microcontroller?

The TS pin (Pin 3) functions as a precision diode anode. A constant current source (10–500 µA) is applied externally; the resulting forward voltage (1.56–2.13 V at 25°C) is measured and converted to temperature using the published TC (5.96 mV/K) and reference curves. No signal conditioning IC is required-only a precision current source and ADC.

Is the body diode suitable for continuous freewheeling conduction?

Yes-the integrated body diode is rated for 30 A continuous (T_C = 140°C) and 488 A pulsed, with V_SD = 0.82 V at 29 A. However, reverse recovery charge (Q_rr = 11.8 µC) and time (t_rr = 490 ns) limit use in high-frequency commutation; it is optimized for low-frequency (<10 kHz), high-current freewheeling in rectifier and disconnect topologies.
