Product details

Overview

IRG4BH20K-SPBF from Infineon (formerly International Rectifier) is a 1200 V, 11 A short-circuit-rated ultrafast IGBT in D2Pak (TO-263) package, optimized for motor control inverters with t_sc = 10 µs at V_CC = 720 V and T_J = 125 °C. It delivers V_CE(on) = 3.17 V @ I_C = 5.0 A, V_GE = 15 V, and E_off = 0.44 mJ, enabling high-efficiency 3-phase AC motor drives up to 5 kW.

For engineers reviewing the IRG4BH20K-SPBF datasheet, IRG4BH20K-SPBF pinout, IRG4BH20K-SPBF application, or IRG4BH20K-SPBF equivalent, key selection criteria include short-circuit withstand time, gate charge (Q_g = 28 nC typ.), thermal resistance (R_θJC = 2.1 °C/W), freewheeling diode pairing compatibility, and D2Pak footprint constraints in compact inverter designs.

Technical Context

This IGBT employs a trench-gate field-stop structure with optimized carrier lifetime control to balance conduction loss (V_CE(on)) and switching speed (t_f = 270 ns typ. @ T_J = 25 °C). Its gate threshold voltage (V_GE(th) = 3.5–6.5 V) and negative temperature coefficient of V_CE(on) support stable parallel operation in multi-device modules.

The device integrates internal emitter inductance (L_E = 7.5 nH) and exhibits C_ies = 435 pF, C_oes = 44 pF, and C_res = 8.3 pF at V_CE = 30 V, enabling predictable EMI behavior when paired with HEXFRED™ diodes and controlled gate drive (R_G = 50 Ω).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	1200 V - supports 720 V DC bus systems with 1.67× safety margin against transients
I_C @ T_C = 100 °C	5.0 A - defines continuous output current capability under industrial heatsink conditions
V_CE(on)	3.17 V @ I_C = 5.0 A, V_GE = 15 V - sets conduction loss of 15.85 W at rated current
t_sc	10 µs @ V_CC = 720 V, T_J = 125 °C - enables robust fault handling without external desaturation protection
Q_g	28 nC typ. - determines gate driver peak current requirement (~560 mA @ 20 ns rise time)
R_θJC	2.1 °C/W - allows 28.6 °C junction rise above case at 60 W dissipation, critical for thermal design
E_off	0.44 mJ @ I_C = 5.0 A, V_CC = 960 V - quantifies turn-off energy loss during PWM switching

Pinout & Package

IRG4BH20K-SPBF uses the industry-standard D2Pak (TO-263AB) thermally enhanced surface-mount package with isolated mounting tab. The three terminals are arranged in a single-row configuration compatible with IPC-7351B SO-2014 footprint.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main power output terminal	Connected to DC bus positive; carries full load current and must be routed with low-inductance copper pour
Gate (G)	Control input	High-impedance MOS-controlled terminal requiring <50 Ω series resistance to damp ringing and limit dV/dt-induced turn-on
Emitter (E)	Power return and reference node	Serves as common source for gate drive and current sensing; internal inductance (7.5 nH) affects shoot-through immunity

Key Features

Feature	Design Value
Short-circuit withstand time	10 µs at 720 V, 125 °C - eliminates need for fast desat detection in 50/60 Hz motor control applications
Ultrafast switching	t_f = 270 ns, E_ts = 0.89 mJ - enables >20 kHz PWM frequency while maintaining <1.2 mJ total loss at 5 A
Tighter parameter distribution	V_CE(on) min/max spread ≤ 1.2 V across production lot - improves current sharing in paralleled configurations
Lead-free construction	RoHS-compliant SnAgCu solder finish - meets IPC-J-STD-020D reflow profile requirements for Pb-free assembly

Applications

Industrial Motor Drives

UPS Inverters

Use Scenario: 3-phase 400 VAC variable-frequency drive for HVAC compressors and pumps.

Use Scenario: Online double-conversion UPS delivering clean 230 VAC output from 400 VDC battery bank.

IC Role / Device Role / Timing Role: High-side switch in full-bridge inverter stage; synchronized with complementary low-side IGBTs.

Use Value: Low E_off (0.44 mJ) reduces thermal stress during frequent battery-to-grid transitions, extending system MTBF.

Solar Microinverters

Electric Vehicle Onboard Chargers

Use Scenario: Single-phase grid-tied microinverter converting 30–60 VDC PV string output to 230 VAC.

IC Role / Device Role / Timing Role: DC-link switching element in H-bridge topology; modulated using unipolar SPWM.

Equivalent & Alternatives

The following parts are listed as comparable options for similar IGBT switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRG4PH20UD-SPBF	Same V_CES (1200 V), lower Q_g (22 nC), higher V_CE(on) (3.4 V typ.)	Better suited for higher-frequency (>30 kHz) resonant converters where gate loss dominates	Select when prioritizing switching speed over conduction loss in low-duty-cycle topologies
FGA25N120ANTD	Higher I_C (25 A), larger TO-247 package, R_θJC = 0.65 °C/W	Targeted at higher-power (10–15 kW) industrial drives requiring forced-air cooling	Choose for scalable designs needing headroom beyond 5 kW or improved thermal margin

Compared with IRG4PH20UD-SPBF, IRG4BH20K-SPBF trades 6 nC higher gate charge for 0.23 V lower saturation voltage-favoring medium-frequency motor drives where conduction loss dominates. Versus FGA25N120ANTD, it offers smaller footprint and lower cost at the expense of thermal headroom and current rating.

FAQ

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

A 50 Ω gate resistor is specified in the datasheet for standard switching characterization (t_f, E_off). Increasing R_G beyond 68 Ω extends turn-off time and increases E_off nonlinearly-exceeding 100 Ω risks incomplete turn-off under high dV/dt conditions. For motor control, 33–47 Ω balances loss and noise immunity.

Can IRG4BH20K-SPBF be paralleled without active current balancing?

Yes-its negative temperature coefficient of V_CE(on) and tight parameter distribution (±5% V_CE(on) spread) enable stable current sharing across up to four devices with matched gate drive and symmetrical PCB layout. Thermal coupling via shared heatsink is required to maintain junction temperature uniformity.

Which HEXFRED™ diode is recommended as a companion freewheeling device?

The datasheet explicitly recommends the UF4007 (600 V, 1 A) or UFT3007 (600 V, 3 A) HEXFRED™ diodes for clamped inductive loads. Their ultra-soft recovery (Q_rr < 25 nC, t_rr < 75 ns) minimizes voltage overshoot and EMI when commutating with this IGBT's 270 ns fall time.

Does the D2Pak package require thermal vias under the tab for standard operation?

Yes-the 2.1 °C/W R_θJC rating assumes a minimum 1"² copper pad on the PCB with ≥6 thermal vias (0.3 mm diameter, filled) connecting to an internal ground plane. Without vias, R_θJA degrades to 40 °C/W, limiting continuous power to <15 W at ambient 50 °C.
