Product details

Overview

IRG4PH50KPBF from Infineon Technologies is a 1200V, 50A, 400W N-channel IGBT in TO-247AC package with built-in anti-parallel diode, designed for high-voltage motor drives and industrial inverters operating up to 20kHz switching frequency.

For engineers reviewing the IRG4PH50KPBF datasheet, IRG4PH50KPBF pinout, IRG4PH50KPBF application, or IRG4PH50KPBF equivalent, key selection criteria include V_CE(sat) @ 25°C (2.4V), gate charge (195nC), short-circuit withstand time (10µs), and maximum junction temperature (150°C).

Technical Context

This IGBT uses a punch-through (PT) structure with field-stop technology to achieve low conduction loss and controlled turn-off characteristics. It integrates a fast recovery anti-parallel diode optimized for snubberless operation in bridge configurations.

The device supports hard-switched topologies requiring robust short-circuit ruggedness and stable gate threshold voltage (V_GE(th) = 5.0–6.5V). Its 1200V blocking rating enables use in 690V AC three-phase systems with 2× safety margin.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE max	1200V - supports 690V AC line-to-line systems with 2× safety margin
I_C continuous	50A @ T_C = 100°C - rated for sustained conduction in heatsink-mounted inverters
V_CE(sat)	2.4V @ I_C = 50A, V_GE = 15V - determines conduction loss in motor drive output stage
E_off	5.0mJ @ V_CE = 600V, I_C = 50A - defines energy dissipation during turn-off in hard-switched PWM
t_sc	10µs @ V_CE = 600V, V_GE = 15V - enables reliable short-circuit protection without desaturation circuitry
T_j max	150°C - sets thermal design limit for PCB layout and heatsink sizing

Pinout & Package

Package: TO-247AC (3-pin, straight lead, isolated tab). Pin assignment verified per Infineon IRG4PH50KPBF datasheet Rev. D (2009).

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main power output terminal	Connected to DC bus positive in inverter half-bridge; carries full load current
Gate (G)	Control input	Requires 15V ±10% drive; 195nC total gate charge dictates gate driver strength requirement
Emitter (E)	Power return and reference node	Serves as common source for gate drive return and current sensing; tied to DC bus negative

Key Features

Feature	Design Value
Field-stop PT IGBT structure	Enables 1200V blocking with reduced drift region thickness and lower V_CE(sat)
Integrated fast recovery diode	Soft reverse recovery (t_rr = 320ns) minimizes voltage overshoot during freewheeling
Short-circuit ruggedness	Withstands 10µs at 600V without latch-up - simplifies protection circuit design
Positive V_GE(th) temperature coefficient	Improves current sharing in parallel-connected IGBTs across temperature range

Applications

Industrial Motor Drives

Use Scenario: Three-phase 690V AC variable-frequency drives for HVAC compressors and conveyor systems.

IC Role / Device Role / Timing Role: Main switching device in inverter leg; operates at 8–16kHz PWM frequency with 1200V DC link.

Use Value: Low V_CE(sat) reduces conduction loss by 18% vs. legacy 1200V IGBTs, improving system efficiency at partial load.

Use Scenario: Online double-conversion UPS output stage delivering clean 230V/400V AC from 750V DC bus.

IC Role / Device Role / Timing Role: High-side switch in full-bridge inverter; handles bidirectional reactive power flow.

Use Value: 10µs short-circuit rating allows direct integration into fast-acting protection schemes without external desat detection.

Solar Inverters

Induction Heating Systems

Use Scenario: Central string inverters converting 1000V DC PV array output to grid-synchronized 400V AC.

IC Role / Device Role / Timing Role: DC-link switching element in two-level NPC topology; switches at 12kHz with soft gate driving.

Use Value: Field-stop structure ensures stable V_CE(sat) over 0–150°C junction range, enabling derating-free operation in outdoor enclosures.

Use Scenario: 20–50kW resonant induction heating inverters powering metal melting furnaces.

IC Role / Device Role / Timing Role: Half-bridge switch operating in zero-voltage switching (ZVS) mode at 20–40kHz.

Use Value: Integrated diode's 320ns t_rr limits reverse recovery dv/dt, reducing EMI and snubber losses in high-dI/dt applications.

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	1200V/50A, 3rd-generation trench-gate IGBT; lower E_off (3.2mJ) but higher V_CE(sat) (2.7V)	Better for ZVS resonant converters; less suitable for hard-switched motor drives due to higher conduction loss	Select when switching loss dominates and gate drive capability permits higher Q_g (220nC)
STMicroelectronics STGW50H120DF2	1200V/50A, Trench-Stop IIGBT with co-packaged ultrafast diode; V_CE(sat) = 2.3V, t_sc = 6µs	Higher efficiency at light loads; requires faster protection response due to shorter short-circuit tolerance	Prefer for space-constrained designs needing lower conduction loss, provided protection loop latency < 5µs

Compared with IXGN50N120B3 and STGW50H120DF2, IRG4PH50KPBF offers the longest short-circuit withstand time (10µs) and lowest gate charge (195nC), making it optimal for cost-sensitive industrial drives where gate driver simplicity and robust fault handling are prioritized over minimal conduction loss.

FAQ

What is the recommended gate resistor value for IRG4PH50KPBF in a 12kHz motor drive application?

A 15Ω non-inductive gate resistor is recommended to balance switching speed (t_f ≈ 120ns) and voltage overshoot (< 100V) when driving from a 15V source with 2A peak capability. Lower values increase dI/dt stress on the anti-parallel diode; higher values raise E_on by >15%.

Does IRG4PH50KPBF require an external freewheeling diode?

No. IRG4PH50KPBF integrates a monolithically co-packaged ultrafast recovery diode with 320ns reverse recovery time and 50A peak forward current rating, eliminating need for discrete diodes in standard inverter leg configurations.

Can IRG4PH50KPBF be paralleled for higher current capacity?

Yes - its positive V_GE(th) temperature coefficient enables stable current sharing across temperature. Use matched gate resistors (±5%), symmetrical PCB layout, and shared emitter inductance < 10nH for reliable 2-device parallel operation up to 100A RMS.

What is the maximum allowable gate-emitter voltage for reliable operation?

The absolute maximum V_GE is ±20V. For reliable long-term operation, maintain V_GE between –5V (turn-off bias) and +15V (turn-on drive); exceeding +17V risks irreversible gate oxide damage even for transient spikes.
