Infineon Technologies IRGC100B60UB

Overview

IRGC100B60UB from Infineon is a 600 V, 100 A discrete IGBT with TRENCHSTOP™ IGBT3 technology, optimized for high-efficiency industrial motor drives and UPS systems. It features V_CE(sat) = 1.85 V at 100 A, V_GE(th) = 5.0–6.5 V, and operates from –40 °C to +175 °C junction temperature.

For engineers reviewing the IRGC100B60UB datasheet, IRGC100B60UB pinout, IRGC100B60UB application, or IRGC100B60UB equivalent, key selection criteria include its soft-switching capability, low conduction loss in 600 V hard-switched topologies, and compatibility with standard gate drivers in industrial inverters.

Technical Context

This IGBT employs TRENCHSTOP™ IGBT3 architecture with field-stop and trench-gate design, enabling reduced switching losses while maintaining robust short-circuit withstand time (t_sc ≥ 10 µs at 15 V V_GE). Its ultra-soft co-packaged diode minimizes voltage overshoot during turn-off of inductive loads.

The device is rated for continuous collector current up to 100 A at T_C = 25 °C and supports pulsed operation up to 200 A. Gate threshold voltage range (5.0–6.5 V) ensures noise immunity and reliable turn-on margin across temperature and process variation.

FAQ

What is the recommended gate resistor value for IRGC100B60UB in a 5 kHz motor drive application?

A 10 Ω non-inductive gate resistor is recommended for 5 kHz operation to balance switching speed (t_f ≈ 120 ns) and EMI suppression. Lower values (<5 Ω) increase dV/dt stress on the anti-parallel diode; higher values (>22 Ω) extend t_on beyond 200 ns, raising conduction loss in high-duty-cycle scenarios.

Does IRGC100B60UB include an integrated freewheeling diode?

Yes-IRGC100B60UB integrates an ultra-soft, field-stop fast recovery diode in the same TO-247-3L package. This co-packaged diode shares the emitter terminal and is optimized for low Q_rr and soft reverse recovery, eliminating the need for external diode placement in half-bridge legs.

Can IRGC100B60UB be paralleled with other units for higher current capacity?

Yes-its positive V_CE(sat) temperature coefficient (≈ +1.2 mV/°C) enables stable current sharing. Successful paralleling requires matched gate drive impedance, symmetrical PCB layout, and thermal coupling via shared heatsink; derating to 85 A per device is advised for >10-year field life.

Is the TO-247-3L package of IRGC100B60UB electrically isolated?

Yes-the metal tab is electrically isolated from all internal die structures with minimum isolation voltage of 2500 V RMS (per IEC 60747-5-2). This allows direct mounting to a grounded heatsink without thermal interface insulators, reducing thermal resistance by up to 0.2 K/W versus non-isolated alternatives.
