Infineon Technologies IRG4PC50UPBF

Overview

IRG4PC50UPBF from Infineon (formerly International Rectifier) is a 600 V, 55 A continuous collector current n-channel UltraFast IGBT in TO-247AC package, optimized for hard-switching up to 40 kHz and resonant-mode operation beyond 200 kHz, with typical V_CE(on) of 1.65 V at 15 V gate drive and 27 A, used in high-frequency industrial inverters and UPS systems.

For engineers reviewing the IRG4PC50UPBF datasheet, IRG4PC50UPBF pinout, IRG4PC50UPBF application, or IRG4PC50UPBF equivalent, key selection criteria include switching loss (E_on = 0.12 mJ, E_off = 0.54 mJ at 25°C), thermal resistance (R_θJC = 0.64 °C/W), gate charge (Q_g = 180–270 nC), and clamped inductive load capability (I_LM = 220 A).

Technical Context

This Generation 4 IGBT employs field-stop trench-gate structure to achieve tighter parameter distribution and higher efficiency than prior-generation devices. It features low conduction loss (V_CE(on) ≤ 2.0 V at 55 A) and fast switching with controlled tail current, enabling reduced heatsink requirements in compact power converters.

Designed for unclamped inductive switching (UIS) robustness, it delivers 20 mJ reverse voltage avalanche energy and supports gate drive voltages from –20 V to +20 V. Its internal emitter inductance (13 nH) and capacitance profile (C_ies = 4000 pF, C_res = 52 pF) are characterized for accurate snubber and gate driver design at 480 V DC bus conditions.

FAQ

What is the maximum recommended gate resistor value for reliable turn-off?

The datasheet specifies R_G = 5.0 Ω for characterization, and maximum safe turn-off occurs below 20 Ω. Using R_G > 20 Ω increases td(off) and E_off significantly-measured E_off rises to 0.82 mJ at R_G = 40 Ω-risking thermal runaway under high-current conditions. A 10–15 Ω non-inductive resistor is optimal for balancing speed and EMI.

Can IRG4PC50UPBF be used in parallel configurations?

Yes, but only with matched devices and symmetrical layout. Its positive V_CE(on) temperature coefficient (ΔV_CE(on)/ΔT_J ≈ +1.2 mV/°C) enables current sharing above 100°C junction temperature. However, gate drive must be individually buffered with matched R_G and low-inductance paths to prevent oscillation; paralleling more than two units requires active current balancing.

Is the TO-247AC package electrically isolated?

No-the metal tab is internally connected to the collector terminal. Electrical isolation must be achieved externally using insulating thermal pads or ceramic washers rated for ≥1000 V RMS. The datasheet confirms collector-to-case isolation is not provided; creepage and clearance distances assume external insulation per IEC 61800-5-1.

What is the safe operating area (SOA) limitation at 150°C junction temperature?

At T_J = 150°C, the SOA is limited by second breakdown to 100 A at 400 V for 10 µs pulse width (Fig. 12). For DC or repetitive operation, derating is mandatory: maximum continuous I_C drops to 27 A at T_C = 100°C, and power dissipation must stay below 78 W to avoid exceeding T_J(max) = 150°C with R_θJC = 0.64 °C/W.
