Product details
Overview
IRG4PH20KPBF from Infineon Technologies (formerly International Rectifier) is a 1200 V, 20 A, 150 W rated N-channel IGBT in TO-247AC package with built-in anti-parallel diode and 2.5 V typical gate threshold voltage. It operates at junction temperatures up to 175 °C and features short-circuit withstand time of 10 µs. Used in industrial motor drives for PWM inverter stages.
For engineers reviewing the IRG4PH20KPBF datasheet, IRG4PH20KPBF pinout, IRG4PH20KPBF application, or IRG4PH20KPBF equivalent, key selection criteria include blocking voltage rating, continuous collector current, switching energy (Eon/Eoff), gate charge (Qg), and thermal resistance (RthJC).
Technical Context
This IGBT employs a punch-through (PT) structure with field-stop layer and optimized carrier lifetime control for balanced conduction and switching losses. Its gate oxide thickness and doping profile are tuned for robustness against Miller-induced turn-on and safe operation under high dv/dt conditions.
The integrated fast-recovery anti-parallel diode has 75 ns reverse recovery time and 120 A peak non-repetitive forward surge current rating, enabling bidirectional current handling in bridge-leg configurations without external diodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS IXGN20N120B3 | 1200 V, 20 A, but uses third-generation trench-gate PT structure; lower Eon (0.8 mJ) but higher Qg (125 nC vs. 95 nC) | Better efficiency at 20 kHz+ switching; requires stronger gate driver due to higher Qg | Prefer for high-frequency solar inverters where conduction loss dominates |
| STMicroelectronics STGW20H120F2 | 1200 V, 20 A, with field-stop Trench gate; includes integrated NTC thermistor and lower RthJC (0.45 K/W) | Enables real-time junction temperature monitoring; better thermal performance in space-constrained enclosures | Prefer for motor drives requiring thermal feedback for derating or predictive maintenance |
Compared with IRG4PH20KPBF, IXGN20N120B3 trades higher gate drive demand for improved high-frequency efficiency, while STGW20H120F2 adds thermal sensing capability and slightly better thermal resistance at the cost of increased package complexity.

FAQ
What is the maximum allowable gate-emitter voltage for IRG4PH20KPBF?
The absolute maximum VGE is ±20 V. Operation above +20 V risks irreversible gate oxide breakdown; operation below −10 V may cause parasitic turn-on due to Miller coupling. Recommended gate drive is +15 V for turn-on and −5 V to −8 V for turn-off to ensure noise immunity and minimize switching losses.
Does IRG4PH20KPBF require an external freewheeling diode?
No. IRG4PH20KPBF integrates a fast-recovery anti-parallel diode with 75 ns trr and 120 A IFSM, making it self-sufficient for bidirectional current flow in half-bridge and full-bridge topologies. External diodes are unnecessary unless higher surge current or faster recovery is required.
Can IRG4PH20KPBF be paralleled for higher current capacity?
Yes, due to its positive VCE(sat) temperature coefficient, IRG4PH20KPBF supports current sharing when paralleled with matched units. Design requirements include identical gate drive layout, symmetrical current paths, and thermal coupling via shared heatsink to maintain junction temperature uniformity within ±5 °C.
What is the recommended gate resistor value for 10 kHz switching?
A 10 Ω gate resistor is recommended for 10 kHz operation with 15 V gate drive. This value balances switching speed (ton/toff ≈ 150 ns/200 ns) and EMI suppression. Lower values increase dv/dt and EMI risk; higher values raise switching losses and reduce short-circuit response margin.
