Product details

Overview

IRG4BC20KD-SPBF from Infineon Technologies is a 600 V, 15 A n-channel IGBT with ultrafast soft-recovery co-packaged diode in TO-220AB package, rated for 60 W at T_C = 100 °C, optimized for motor control inverters and UPS systems requiring low conduction loss and controlled switching behavior.

For engineers reviewing the IRG4BC20KD-SPBF datasheet, IRG4BC20KD-SPBF pinout, IRG4BC20KD-SPBF application, or IRG4BC20KD-SPBF equivalent, key selection criteria include V_CE(sat) = 2.3 V @ I_C = 7.5 A, t_rr = 120 ns, Q_G = 38 nC, R_G = 6 Ω, and integrated diode reverse recovery charge Q_rr = 95 nC - all critical for hard-switched 20–50 kHz power stages.

Technical Context

This IGBT employs punch-through (PT) structure with field-stop layer and soft-recovery anti-parallel diode, enabling balanced trade-off between switching speed and voltage overshoot. Its gate threshold voltage V_GE(th) = 5.0 V and transconductance g_fs = 5.5 S support stable drive under ±15 V gate bias with minimal Miller-induced turn-on risk.

Thermal resistance R_thJC = 1.25 °C/W and maximum junction temperature T_J = 150 °C allow sustained operation in forced-air-cooled industrial drives. The device is characterized for square-wave switching at 50% duty cycle, 20 µs pulse width, and V_CC = 480 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE max	600 V - supports 400 V DC bus designs with 50% voltage margin for transient clamping.
I_C continuous	15 A @ T_C = 100 °C - enables compact heatsink sizing in 1–2 kW motor drives.
V_CE(sat)	2.3 V @ I_C = 7.5 A, V_GE = 15 V - reduces conduction loss to ~17 W at full load, improving thermal headroom.
t_rr	120 ns @ I_F = 8 A, V_R = 200 V, T_J = 125 °C - limits diode reverse recovery stress during hard commutation.
Q_G	38 nC @ V_GE = 15 V - determines gate driver peak current requirement (~1.9 A for 20 ns rise time).
E_off	1.2 mJ @ V_CC = 480 V, I_C = 9 A, R_G = 6 Ω - sets switching loss budget for 25 kHz PWM operation.
R_thJC	1.25 °C/W - defines thermal path efficiency from junction to case, critical for derating calculations.

Pinout & Package

IRG4BC20KD-SPBF uses TO-220AB package with insulated tab, 3-pin configuration: Collector (pin 1), Gate (pin 2), Emitter (pin 3). Pin 1 connects directly to internal IGBT collector die; pin 3 is emitter common for both IGBT and diode; pin 2 is isolated gate terminal with 1000 V isolation rating.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Collector)	Main high-side power terminal	Carries full load current to DC bus; electrically tied to metal tab - requires insulating mounting hardware.
Pin 2 (Gate)	Control input	High-impedance MOS-gated terminal; requires 15 V drive with <6 Ω series resistance to limit ringing.
Pin 3 (Emitter)	Power return and reference node	Common emitter for IGBT and anti-parallel diode; serves as gate drive return and current sense reference point.

Key Features

Feature	Design Value
Ultrafast soft-recovery diode	Q_rr = 95 nC, t_rr = 120 ns - minimizes voltage spikes and EMI during diode commutation in bridge legs.
Low V_CE(sat)	2.3 V @ 7.5 A - reduces conduction loss by 18% vs. standard 600 V IGBTs, lowering heatsink cost.
Field-stop PT structure	Enables 600 V blocking with thin drift region - improves switching speed without sacrificing ruggedness.
150 °C max junction temp	Supports operation in sealed enclosures with ambient up to 70 °C and 30 K rise across heatsink.
TO-220AB insulated tab	1000 V isolation between tab and emitter - eliminates need for mica washers in grounded-heatsink layouts.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STGP15H60DF	V_CE(sat) = 2.4 V @ 7.5 A; Q_G = 42 nC; no soft-recovery diode	Higher diode recovery loss increases EMI filtering burden in bridge configurations	Prefer when lower gate charge tolerance is acceptable and external diode selection is desired
IXGH15N60B3	V_CE(sat) = 2.2 V; t_rr = 200 ns; Q_rr = 180 nC; non-soft diode	Longer reverse recovery increases voltage stress on complementary switch during turn-on	Choose only if higher V_CE(sat) margin is needed and layout includes RC snubbers

Compared with STGP15H60DF and IXGH15N60B3, IRG4BC20KD-SPBF delivers superior diode softness and lower total switching loss at 25–40 kHz, making it optimal for compact, filter-light inverter designs where EMI compliance and thermal density are critical.

FAQ

What is the maximum gate-emitter voltage rating for IRG4BC20KD-SPBF?

The absolute maximum V_GE is ±20 V, with recommended operating range of –5 V (turn-off) to +15 V (turn-on). Exceeding +15 V increases risk of gate oxide degradation over time, while negative bias below –5 V offers no additional noise immunity benefit and may increase driver complexity.

Can IRG4BC20KD-SPBF be used in parallel configurations?

Yes, but only with matched devices and individual gate resistors (R_G ≥ 6 Ω) to ensure current sharing. Thermal coupling must be identical across paralleled units, and gate drive traces must be symmetrical to avoid dynamic imbalance. Derate total current by 20% for two devices in parallel.

Does the co-packaged diode support synchronous rectification?

No - the integrated diode is a standard ultrafast soft-recovery type, not a MOSFET-based synchronous rectifier. It cannot be actively controlled and operates only in forward conduction or reverse recovery mode. For synchronous rectification, an external N-channel MOSFET must be used in anti-parallel configuration.

What is the short-circuit withstand time at 125 °C junction temperature?

IRG4BC20KD-SPBF sustains short-circuit conditions for 10 µs at T_J = 125 °C and V_CC = 480 V before thermal runaway. This value is measured under gate-voltage-clamped conditions (V_GE = 15 V) and requires fast desaturation detection circuitry to trigger shutdown within this window.
