Infineon Technologies IRGP6650D-EPBF

Overview

IRGP6650D-EPBF from Infineon Technologies (formerly International Rectifier) is a 600 V, 80 A insulated gate bipolar transistor with integrated ultrafast soft-recovery diode in TO-247AD package. It delivers 1.65 V typical V_CE(on) at 35 A and 15 V gate drive, supports 5 µs short-circuit withstand time at 150 °C, and operates up to 175 °C junction temperature-designed for high-efficiency welding inverters and H-bridge motor drives.

For engineers reviewing the IRGP6650D-EPBF datasheet, IRGP6650D-EPBF pinout, IRGP6650D-EPBF application, or IRGP6650D-EPBF equivalent, key selection criteria include its square RBSOA at 175 °C, low 0.49 °C/W IGBT junction-to-case thermal resistance, clamped inductive load rating of 140 A, and optimized diode reverse recovery (E_rec = 165 µJ at 175 °C).

Technical Context

This device integrates an n-channel IGBT and a co-packaged ultrafast soft-recovery diode in a single TO-247AD outline. Its positive V_CE(on) temperature coefficient enables stable current sharing in parallel configurations, while the 5 µs short-circuit SOA allows robust protection circuit design without sacrificing switching speed.

The IGBT features 75 nC total gate charge and 30 nC gate-to-collector charge, enabling fast turn-on (t_d(on) = 40 ns) and controlled turn-off (t_d(off) = 120 ns at 175 °C). Diode parameters include 1.30 V forward voltage at 8 A and 175 °C, 50 ns reverse recovery time, and 14 A peak reverse recovery current under specified test conditions.

Key Specifications

Pinout & Package

IRGP6650D-EPBF uses the TO-247AD package: three-tab, isolated-mount, industry-standard outline with collector tab electrically connected to the IGBT collector and diode cathode. The package provides 0.24 °C/W case-to-sink thermal resistance on greased flat surfaces and supports 1.1 N·m mounting torque.

FAQ

What is the maximum allowable gate-emitter voltage for IRGP6650D-EPBF?

The absolute maximum continuous gate-to-emitter voltage is ±20 V. Exceeding this rating-even briefly-risks permanent gate oxide damage. Gate drive circuits must clamp transients using Zener diodes or active clamping, especially during high di/dt switching events where parasitic inductance can induce overshoot beyond the 15 V nominal drive level.

Can IRGP6650D-EPBF be paralleled for higher current capacity?

Yes-its positive V_CE(on) temperature coefficient ensures natural current sharing across paralleled units. Successful implementation requires matched gate drive paths (identical RG and trace length), symmetrical main current routing, and shared heatsinking to maintain ≤2 °C inter-device temperature difference at full load.

How does the integrated diode differ from standard FRDs in this device?

The co-packaged diode features ultrafast soft recovery with 50 ns t_rr and low stored charge (Q_RR ≈ 220 nC), minimizing voltage overshoot and EMI during commutation. Unlike standard fast recovery diodes, its softness factor (peak I_RR/di/dt slope) is optimized to prevent oscillatory turn-off in hard-switched H-bridges.

Is IRGP6650D-EPBF suitable for space-constrained designs?

Its TO-247AD package offers high power density (153 W at T_C = 100 °C) but requires ≥1.1 N·m mounting torque and flat, greased heatsink contact. For ultra-compact layouts, thermal simulation must confirm junction temperature stays ≤175 °C under worst-case ambient and airflow conditions-especially given its 0.49 °C/W R_θJC.
