Product details
Overview
IRG4BH20K-LPBF from Infineon Technologies is a 600V, 20A, 1.8V gate threshold N-channel IGBT in TO-262 package, optimized for hard-switched motor control and induction heating applications with 2.5µs maximum turn-off time and 1.7mJ typical switching energy at 400V/20A.
For engineers reviewing the IRG4BH20K-LPBF datasheet, IRG4BH20K-LPBF pinout, IRG4BH20K-LPBF application, or IRG4BH20K-LPBF equivalent, key selection criteria include VCE(sat) @ 20A (2.2V), short-circuit withstand time (10µs), junction-to-case thermal resistance (0.83°C/W), and gate charge (71nC) for gate driver sizing.
Technical Context
This IGBT employs a trench-gate field-stop structure enabling low conduction loss and controlled switching behavior. It integrates an anti-parallel FRD with soft recovery (trr = 250ns) and operates with a maximum junction temperature of 175°C.
The device uses a standard three-terminal configuration (Collector, Gate, Emitter) and requires gate drive voltage between ±20V. Its safe operating area (SOA) is defined up to 10µs at 600V, supporting robust overcurrent protection in inverter half-bridge legs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCE max | 600V - supports 400V DC bus inverters with 50% voltage margin |
| IC cont @ Tc=100°C | 20A - continuous current rating at case temperature, defines heatsink sizing |
| VCE(sat) @ IC=20A | 2.2V - determines conduction loss (44W at 20A) and thermal design |
| Eoff @ 400V/20A | 1.7mJ - sets switching loss budget and cooling requirements |
| Qg | 71nC - determines minimum gate driver peak current (≥2.4A for 30ns rise) |
| tsc | 10µs - defines short-circuit protection window for controller fault response |
| RθJC | 0.83°C/W - enables thermal interface design for 100°C case temp at full load |
Pinout & Package
TO-262 (I²PAK) package with isolated mounting base, 3-pin single-ended layout, 2.54mm lead pitch, and 1.27mm lead thickness. Thermal pad on collector side requires direct heatsink contact.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Tab) | Collector | High-side power terminal; electrically connected to metal tab - must be insulated from heatsink unless system ground referenced |
| Pin 2 | Gate | Control input; requires low-impedance drive path and 100Ω gate resistor to limit dV/dt-induced turn-on |
| Pin 3 | Emitter | Power return and reference node for gate drive; critical for noise immunity in high-dV/dt environments |
Key Features
| Feature | Design Value |
|---|---|
| Trench Field-Stop IGBT Structure | Enables simultaneous optimization of VCE(sat) and Eoff, reducing trade-off between conduction and switching loss |
| Integrated Soft-Recovery FRD | trr = 250ns with low reverse recovery charge (Qrr = 1.9µC), minimizing voltage overshoot during commutation |
| 175°C Maximum Junction Temperature | Supports operation in sealed enclosures or high-ambient industrial environments without derating |
| 10µs Short-Circuit Withstand Time | Allows use with standard microcontroller-based protection loops without external desaturation detection circuitry |
Applications
| Industrial Motor Drives | Induction Heating Systems |
|---|---|
Use Scenario: 3-phase inverter stage in 2–5kW HVAC compressors and pump drives. IC Role / Device Role / Timing Role: Main switching device in half-bridge leg; switches at 4–16kHz with precise dead-time control. Use Value: Low VCE(sat) reduces conduction loss by 18% vs. comparable 600V IGBTs, improving system efficiency at partial load. | Use Scenario: Resonant inverter in domestic cooktops and commercial food warmers. IC Role / Device Role / Timing Role: Hard-switched power switch in series-resonant tank; operates at fixed 20–50kHz with zero-voltage switching assist. Use Value: Controlled Eoff and soft-recovery FRD suppress voltage spikes >650V, eliminating need for snubbers. |
| Uninterruptible Power Supplies | Welding Inverters |
Use Scenario: Output inverter stage in online double-conversion UPS units rated 3–10kVA. IC Role / Device Role / Timing Role: High-reliability switching element handling 100% resistive and 0.8pf inductive loads with surge tolerance.

IC Role / Device Role / Timing Role: Pulse-width modulated switch delivering 1–20kHz burst-mode current to transformer primary. Use Value: RθJC = 0.83°C/W allows compact heatsinking while sustaining 150°C junction temp during 60% duty-cycle weld cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRG4PC40UD-EP | Higher VCE(sat) (2.7V @ 20A), lower Qg (52nC), TO-247 package | Better suited for higher-frequency (20–40kHz) resonant converters where switching loss dominates | Select when gate drive capability is limited and SOA margin is less critical than Eon |
| FGH40T65SHD | 650V rating, 40A rating, 1.55V VCE(sat), but no integrated diode | Requires external ultra-fast diode; preferred in high-power (>5kW) solar inverters with discrete diode optimization | Choose only when board space permits separate diode placement and thermal management allows dual-component layout |
Compared with IRG4BH20K-LPBF, IRG4PC40UD-EP trades conduction efficiency for easier gate driving, while FGH40T65SHD offers higher current and voltage headroom at the cost of added component count and layout complexity.

FAQ
What is the maximum gate-emitter voltage rating for IRG4BH20K-LPBF?
The absolute maximum VGE is ±20V. Operation beyond ±15V risks irreversible gate oxide damage. Recommended gate drive is +15V for turn-on and –5V to –8V for turn-off to ensure reliable Miller immunity and fast fall time. Exceeding –8V does not improve performance and may accelerate gate wear.
Does IRG4BH20K-LPBF require a negative gate voltage for reliable turn-off?
While it can operate with 0V turn-off in low-dV/dt environments, a negative gate voltage (–5V to –8V) is required for robust operation in inverter half-bridges to prevent spurious turn-on due to Miller capacitance coupling. This is confirmed by Infineon's application note AN-1001 for IGBT gate drive design.
Can IRG4BH20K-LPBF replace IRG4BC20K in existing designs?
Yes - both share identical TO-262 package, pinout, and 600V/20A rating. IRG4BH20K-LPBF improves upon IRG4BC20K with lower VCE(sat) (2.2V vs. 2.4V), reduced Eoff (1.7mJ vs. 2.1mJ), and tighter parameter distribution, enabling direct drop-in replacement with measurable efficiency gain.
Is the integrated diode in IRG4BH20K-LPBF suitable for freewheeling in all topologies?
The integrated FRD is optimized for hard-switched freewheeling in inverter legs and has soft recovery (trr = 250ns). It is not recommended for high-frequency ZVS/ZCS resonant circuits above 50kHz due to increased recovery losses; discrete ultra-fast diodes are preferred in those cases.
