Infineon Technologies IPDQ60R040S7XTMA1

Overview

IPDQ60R040S7XTMA1 from Infineon is a 600 V, 40 mΩ CoolMOS™ SJ S7 superjunction MOSFET in PG-HDSOP-22-1 package with Kelvin Source pin, optimized for static switching and high-current line rectification in SMPS, UPS, solar inverters, and solid-state relays. It delivers 207 A pulsed drain current, 0.82 V body diode forward voltage, and 83 nC total gate charge.

For engineers reviewing the IPDQ60R040S7XTMA1 datasheet, IPDQ60R040S7XTMA1 pinout, IPDQ60R040S7XTMA1 application, or IPDQ60R040S7XTMA1 equivalent, key selection criteria include R_DS(on) stability at 150 °C, dv/dt ruggedness (20 V/ns), Kelvin Source layout compatibility, and top-side cooling requirements for high-power industrial designs.

Technical Context

This device implements Infineon's 7th-generation CoolMOS™ superjunction architecture with charge compensation trenches, enabling ultra-low R_DS(on) of 40 mΩ at 12 V gate drive while maintaining 600 V blocking capability. Its internal Kelvin Source (Pin 2) separates driver return path from power source, reducing gate loop inductance and improving switching control under high di/dt.

The PG-HDSOP-22-1 package integrates a thermally enhanced exposed tab (Pins 12–22 + Tab) for top-side cooling and supports >272 W power dissipation at T_C = 25 °C. Its 0.46 °C/W junction-to-case thermal resistance enables compact heatsink integration in space-constrained industrial power stages.

FAQ

Can Pin 2 (Kelvin Source) be connected to the same net as Pins 3–11 (Power Source)?

No. Pin 2 must be routed separately to the gate driver's source reference and never shorted to Pins 3–11. Mixing these paths introduces gate loop inductance that distorts the 5.4 V gate plateau, causing inconsistent turn-off timing and potential shoot-through in half-bridge configurations.

What is the maximum recommended gate resistor value for hard-switching at 100 kHz?

For 100 kHz hard-switching with V_DD = 300 V and I_D = 13 A, a 4.7 Ω gate resistor is recommended. This balances 23 ns turn-on delay and 120 ns turn-off delay while limiting peak gate current to <3 A and preserving dv/dt immunity per datasheet Figure 9 test conditions.

Is this device suitable for synchronous rectification in LLC resonant converters?

No. The 360 ns reverse recovery time and 5.5 µC Q_rr make it unsuitable for >200 kHz synchronous rectification. It is qualified only for low-frequency (<100 kHz), high-current static switching-e.g., active bridge rectifiers or DC contactors-not high-speed freewheeling.

Does the PG-HDSOP-22-1 package require special reflow profile considerations?

Yes. The package is MSL1 rated for peak reflow at 260 °C, but its large copper tab demands extended preheat (150–180 °C for 90–120 s) and controlled ramp-up (≤2 °C/s) to prevent solder voiding and delamination. Use nitrogen atmosphere and verify thermal profiling per IPC-J-STD-020.
