Infineon Technologies IRGP6650DPBF

Overview

IRGP6650DPBF from Infineon Technologies (formerly International Rectifier) is a 600 V, 80 A rated insulated gate bipolar transistor with integrated ultrafast soft-recovery diode in TO-247AC package. It delivers 1.65 V typical V_CE(on) at 35 A/15 V_GE/25°C, 5 µs short-circuit withstand capability, and square RBSOA up to 175°C junction temperature-designed for high-efficiency welding inverters and H-bridge DC-AC converters.

For engineers reviewing the IRGP6650DPBF datasheet, IRGP6650DPBF pinout, IRGP6650DPBF application, or IRGP6650DPBF equivalent, key selection criteria include clamped inductive load current (140 A), thermal resistance R_θJC (0.49 °C/W for IGBT), reverse recovery energy (165 µJ at 175°C), and gate charge (75 nC), all critical for hard-switched industrial power stages.

Technical Context

This device integrates an IGBT and co-packaged ultrafast soft-recovery diode in a single TO-247AC housing, enabling compact full-bridge topologies without discrete diode placement. Its positive V_CE(on) temperature coefficient ensures stable current sharing in parallel configurations.

The 5 µs short-circuit safe operating area (SCSOA) at 150°C case temperature and 400 V bus voltage supports robust overcurrent protection in welder primary-side switching. Square RBSOA up to 175°C and 140 A peak clamped inductive current confirm ruggedness under transient overload conditions.

Key Specifications

Pinout & Package

IRGP6650DPBF uses the TO-247AC package: three-terminal through-hole outline with isolated tab (collector), standard lead pitch (5.4 mm), and 1.1 N·m mounting torque specification. The metal tab is electrically connected to the collector terminal.

FAQ

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

The IRGP6650DPBF supports 50 A continuous collector current at T_C = 100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the TO-247AC package and internal chip design, not electrical degradation. Operation above this value risks exceeding 175°C junction temperature even with adequate heatsinking.

Does the integrated diode share the same thermal path as the IGBT die?

Yes-the diode and IGBT are co-packaged in a single TO-247AC housing with shared case-to-sink thermal interface. Thermal resistance R_θJC is separately specified as 0.49 °C/W for the IGBT and 3.35 °C/W for the diode, confirming distinct but thermally coupled junctions. Both contribute to total power dissipation measured at the case.

Can IRGP6650DPBF be paralleled with identical units without external current-sharing components?

Yes-its positive V_CE(on) temperature coefficient ensures automatic current balancing during steady-state conduction. However, matched gate drive loop inductance and layout symmetry are mandatory to prevent dynamic imbalance during switching transients, especially at high dI/dt (>1 kA/µs).

What is the recommended gate resistor value for 400 V, 35 A hard-switched operation at 175°C junction temperature?

Based on Figure 17 in the datasheet, a 10 Ω gate resistor achieves ~120 ns t_d(off) and ~60 ns t_f at 175°C, balancing switching speed against E_off (930 µJ) and voltage overshoot. Lower values (<5 Ω) increase EMI risk; higher values (>15 Ω) raise total switching loss beyond 1570 µJ, compromising thermal design.
