Product details

Overview

IRG4BC20S from Infineon (formerly International Rectifier) is a 600 V, 15 A, n-channel IGBT in TO-220AB package with 2.2 Ω typical collector-emitter saturation voltage (V_CE(sat)) at 10 A and 15 V gate drive, optimized for motor control inverters and UPS systems operating up to 150 °C junction temperature.

For engineers reviewing the IRG4BC20S datasheet, IRG4BC20S pinout, IRG4BC20S application, or IRG4BC20S equivalent, key selection criteria include its 600 V blocking rating, 15 A DC current capability, 2.2 Ω V_CE(sat), 13 W power dissipation at T_C = 25 °C, and 100 ns typical turn-off time under specified test conditions.

Technical Context

This IGBT integrates a co-packaged ultrafast soft-recovery anti-parallel diode with 75 ns reverse recovery time and 100 A peak non-repetitive surge current rating. Its gate threshold voltage is 5.0 V (min), and total gate charge is 75 nC at V_GE = 15 V, enabling efficient switching in hard-switched 20–100 kHz applications.

The device uses trench-gate field-stop technology to achieve low conduction loss while maintaining robust short-circuit withstand time of 10 µs at V_CC = 480 V and T_J = 150 °C. Thermal resistance R_thJC is 1.9 °C/W, supporting high-power density designs with forced-air or heatsink cooling.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	600 V - Maximum repetitive blocking voltage across collector-emitter, defining safe operation in 400 V DC bus systems with margin.
I_C (DC)	15 A - Continuous collector current at T_C = 100 °C, enabling use in 1–2 kW motor drives without derating.
V_CE(sat)	2.2 Ω - Typical saturation voltage at I_C = 10 A, V_GE = 15 V; directly determines conduction loss and thermal load.
t_off	100 ns - Turn-off delay plus fall time at V_CC = 480 V, I_C = 10 A, R_G = 50 Ω; sets minimum practical switching frequency limit.
Q_G	75 nC - Total gate charge at V_GE = 15 V; determines required gate driver peak current and drive power.
R_thJC	1.9 °C/W - Junction-to-case thermal resistance; used to calculate junction temperature rise under given power dissipation and heatsink conditions.
E_off	1.2 mJ - Turn-off energy at V_CC = 480 V, I_C = 10 A, T_J = 25 °C; critical for loss budgeting in high-frequency PWM stages.

Pinout & Package

IRG4BC20S is housed in a TO-220AB package with insulated tab, featuring three terminals: Collector (pin 1), Gate (pin 2), and Emitter (pin 3). The case is electrically isolated from the collector, allowing direct mounting to grounded heatsinks without additional insulation.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	High-side power switch node	Connects to DC bus positive; carries full load current and must be routed with low-inductance layout.
Gate (G)	Control input	Requires 15 V ±10 % drive with <100 ns rise/fall; sensitive to noise-needs local 100 nF decoupling.
Emitter (E)	Power return reference	Serves as common source for gate drive and current sensing; must be low-impedance path to minimize shoot-through risk.

Key Features

Feature	Design Value
Ultrafast soft-recovery diode	Co-packaged diode with 75 ns t_rr and soft recovery factor >1.5 reduces EMI and voltage overshoot during freewheeling.
Trench Field-Stop IGBT structure	Enables 600 V/15 A rating with 2.2 Ω V_CE(sat), balancing conduction and switching losses for 20–50 kHz operation.
10 µs short-circuit withstand time	Guaranteed at V_CC = 480 V, T_J = 150 °C-supports fault protection in industrial motor drives without external desat detection.
Lead-free (P suffix)	RoHS-compliant assembly with matte tin lead finish; compatible with standard SnPb and lead-free reflow profiles.
Isolated TO-220AB package	2500 V_RMS isolation between case and collector enables direct heatsink mounting on grounded chassis.

Applications

Use Value: 100 ns t_off and 1.2 mJ E_off enable >95.2 % inverter efficiency at rated load, meeting UL 1778 efficiency requirements.

Solar Microinverter

Induction Heating Half-Bridge

Use Scenario: Single-phase 300 W microinverter interfacing PV panel to grid with MPPT and anti-islanding.

IC Role / Device Role / Timing Role: High-side switch in H-bridge output stage; commutates 25 A peak AC current at 45 kHz with zero-voltage switching assist.

Use Value: Co-packaged soft diode eliminates need for external fast recovery diode, saving 12 mm² PCB area and reducing BOM count by one component.

Use Scenario: 1.8 kW resonant induction heater for cooktops using series-resonant topology at 25–50 kHz.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STGW20NB60WD	600 V/20 A, 1.8 Ω V_CE(sat), no co-packaged diode; requires external ultrafast diode.	Higher current rating but larger footprint (TO-247); needs extra diode and layout space.	Preferred where higher continuous current (>18 A) is required and board space permits TO-247 and discrete diode.
FGA25N120ANTD	1200 V/25 A, 2.4 Ω V_CE(sat), integrated diode; higher voltage rating but higher conduction loss.	Designed for 600–800 V DC bus systems; over-specified for 400 V applications, increasing cost and loss.	Only suitable if future system voltage scaling to 600 V DC is planned; otherwise inefficient for existing 400 V designs.

Compared with STGW20NB60WD and FGA25N120ANTD, IRG4BC20S offers optimal balance of voltage rating, conduction loss, and integration for 400 V DC bus applications-delivering lower system cost and smaller footprint than the 1200 V part and simpler layout than the discrete-diode alternative.

FAQ

What is the maximum allowable gate-emitter voltage for IRG4BC20S?

The absolute maximum gate-emitter voltage is ±20 V. Operation above +20 V risks permanent gate oxide damage, while negative voltage beyond –20 V may cause latch-up. Recommended drive is +15 V for turn-on and –5 V to –10 V for turn-off to ensure robust noise immunity and fast switching.

Does IRG4BC20S require a gate resistor, and what value is recommended?

Yes-a gate resistor is mandatory to control dV/dt and prevent oscillation. For 20–50 kHz operation with a 2 A peak gate driver, a 22 Ω series resistor is recommended. This provides ~100 ns rise/fall times and limits peak gate current to <700 mA, avoiding driver overstress.

Can IRG4BC20S be used in parallel configurations?

Parallel operation is not recommended due to parameter spread in V_CE(sat) and threshold voltage. Mismatches exceeding ±5 % can cause current imbalance >30 %. If required, active current sharing (e.g., emitter resistors ≥0.1 Ω) and matched gate drive paths are essential-consult Infineon AN-1001 before implementation.

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

At T_J = 150 °C, the SOA is limited to 10 A at 400 V for DC operation, or 20 A at 200 V. Pulse operation (t ≤ 100 µs) extends this to 30 A at 400 V. Exceeding these boundaries risks thermal runaway or secondary breakdown-always verify with the published SOA curve (Fig. 6 in datasheet).
