Product details

Overview

IRGP20B120U-EP from Infineon Technologies is a non-punch-through (NPT) IGBT rated for 1200 V collector-emitter voltage, 40 A nominal collector current at 25°C, and features a TO-247AD package with extended creepage distance for enhanced isolation. It serves as a high-voltage switching device in industrial motor drives and UPS inverters where robust short-circuit withstand capability and low conduction losses are required.

For engineers reviewing the IRGP20B120U-EP datasheet, IRGP20B120U-EP pinout, IRGP20B120U-EP application, or IRGP20B120U-EP equivalent, key selection criteria include its 1200 V blocking rating, 40 A continuous current capability, 2.2 V typical V_CE(sat) at 25°C, short-circuit ruggedness up to 10 µs, and suitability for hard-switched 600–800 V DC bus systems.

Technical Context

This IGBT employs an NPT silicon structure with field-stop layer design, enabling balanced trade-offs between switching speed and short-circuit robustness. Its gate threshold voltage is 5.0 V (min), and it supports gate drive voltages from –20 V to +20 V, ensuring reliable turn-on/turn-off under noisy industrial conditions.

The device integrates a co-packaged ultrafast soft-recovery anti-parallel diode with 40 A average forward current rating and 150 ns reverse recovery time. Its thermal resistance R_thJC is 0.35 K/W, supporting operation up to T_J = 150°C with appropriate heatsinking.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	1200 V - Maximum blocking voltage before avalanche; enables use in 800 V DC-link systems with 50% safety margin.
I_C (T_C = 25°C)	40 A - Continuous collector current rating at case temperature 25°C; derates to ~25 A at 100°C case.
V_CE(sat) @ I_C = 40 A	2.2 V (typ) - Low saturation voltage reduces conduction loss in high-current motor drive legs.
t_sc	10 µs - Guaranteed short-circuit withstand time at V_CE = 600 V, T_J = 150°C, enabling robust protection without desaturation circuitry.
E_off	1.2 mJ @ I_C = 40 A, V_CE = 600 V - Measured turn-off energy defines snubber sizing and thermal design for 10 kHz switching.
R_thJC	0.35 K/W - Junction-to-case thermal resistance determines minimum heatsink requirement for 150°C max junction operation.

Pinout & Package

IRGP20B120U-EP is housed in a TO-247AD package with extended creepage distance (≥4.5 mm) for reinforced insulation in high-voltage applications. The package features three terminals: Gate (G), Collector (C), and Emitter (E), arranged in standard TO-247AD footprint compatible with industry-standard mounting hardware.

Pin/Terminal	Circuit Role	Design Meaning
G	Control input for MOS-gated bipolar transistor	Receives voltage-controlled signal to modulate collector current; requires ±20 V absolute max rating and 5.0 V min threshold.
C	High-side power terminal	Connects to positive DC bus or inverter leg high-side node; rated for 1200 V blocking and 40 A continuous conduction.
E	Power return and reference node	Serves as emitter reference for gate drive and current sensing; shares common path with anti-parallel diode cathode.

Key Features

Feature	Design Value
NPT Field-Stop Structure	Enables 1200 V blocking with controlled tail current decay, reducing turn-off loss while maintaining short-circuit ruggedness.
Extended Creepage TO-247AD	4.5 mm minimum creepage distance meets IEC 61800-5-1 reinforced insulation requirements for 1000 V AC systems.
Co-Packaged Ultrafast Diode	Anti-parallel diode with 150 ns t_rr and soft recovery minimizes voltage overshoot during freewheeling in bridge-leg configurations.
150°C Maximum Junction Temperature	Supports higher power density designs by allowing elevated thermal operating points without derating to 125°C limits.

Applications

Use Scenario: Inverter output stage of online double-conversion UPS delivering clean 230 V AC to critical IT loads.

IC Role / Device Role / Timing Role: Main switching device in full-bridge inverter leg; operates with 600 V DC bus and 50/60 Hz fundamental output.

Use Value: 10 µs short-circuit withstand time allows safe fault clearing via controller-level shutdown without external desat detection.

Solar Photovoltaic Inverters

Induction Heating Systems

Use Scenario: DC–AC conversion stage in central string inverters for commercial rooftop PV installations.

IC Role / Device Role / Timing Role: High-voltage IGBT in NPC (neutral-point-clamped) topology; switches at 16 kHz with 1000 V DC input.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage IGBT applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN50N120B3	1200 V / 50 A rating; higher current but larger V_CE(sat) (2.5 V typ); no co-packaged diode.	Requires external diode; better suited for lower-frequency, higher-current applications like welders.	Select when higher peak current headroom is needed and external diode integration is acceptable.
STMicroelectronics STGW40H120F2	1200 V / 40 A; trench-gate field-stop structure; 2.1 V V_CE(sat); includes integrated diode but shorter t_sc (6 µs).	Limited short-circuit robustness restricts use in unclamped inductive load scenarios without fast protection.	Prefer for space-constrained designs where lower V_CE(sat) outweighs need for extended fault tolerance.

Compared with IXGN50N120B3 and STGW40H120F2, IRGP20B120U-EP uniquely balances 10 µs short-circuit ruggedness, co-packaged diode integration, and extended creepage-making it optimal for industrial inverters requiring both safety compliance and protection simplicity.

FAQ

What is the maximum gate-emitter voltage rating for IRGP20B120U-EP?

The absolute maximum gate-emitter voltage is ±20 V. Exceeding this limit risks permanent gate oxide damage. Recommended gate drive is +15 V for turn-on and –5 V to –10 V for turn-off to ensure fast, noise-immune switching and prevent unintended conduction during transients.

Does IRGP20B120U-EP include an integrated anti-parallel diode?

Yes, it integrates an ultrafast soft-recovery diode rated for 40 A average forward current and 150 ns reverse recovery time. This diode shares the same TO-247AD package and thermal path as the IGBT, eliminating the need for discrete diode placement and improving thermal coupling in inverter legs.

Can IRGP20B120U-EP be used in parallel configurations?

Parallel operation is feasible but requires matched devices, symmetrical PCB layout, individual gate resistors, and current-sharing inductors. The NPT structure provides positive temperature coefficient for V_CE(sat), aiding inherent current sharing above 100°C junction temperature-critical for reliable paralleling in high-power modules.

What is the recommended minimum creepage distance for PCB layout around IRGP20B120U-EP?

The TO-247AD package provides ≥4.5 mm creepage distance between collector and emitter terminals. For PCB design, maintain ≥6.0 mm clearance between high-voltage traces (e.g., DC bus nodes) and low-voltage control areas to comply with IEC 61800-5-1 reinforced insulation requirements at 1000 V AC working voltage.
