Product details

Overview

IRG4PH20KD from Infineon Technologies is a 1200 V, 20 A, 150 °C rated N-channel IGBT in TO-247AC package with 2.0 V typical V_CE(sat) at 20 A and 150 °C, designed for industrial motor drives and UPS inverters requiring high blocking voltage and robust short-circuit capability.

For engineers reviewing the IRG4PH20KD datasheet, IRG4PH20KD pinout, IRG4PH20KD application, or IRG4PH20KD equivalent, key selection criteria include V_CE(sat) drift over temperature, turn-off switching loss (E_off = 1.8 mJ at T_j = 150 °C), short-circuit withstand time (10 µs), gate charge (Q_g = 95 nC), and maximum junction temperature rating.

Technical Context

This IGBT employs a punch-through (PT) structure with field-stop layer and optimized carrier lifetime control to balance conduction and switching losses. It features a co-packaged ultrafast soft-recovery anti-parallel diode with 1200 V reverse blocking and 20 A forward current rating.

The device operates with standard ±15 V gate drive, requires minimum 10 V gate-emitter threshold (V_GE(th)) for turn-on, and exhibits positive temperature coefficient for V_CE(sat), enabling inherent current sharing in parallel configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE max	1200 V - supports DC bus voltages up to 800 V in three-phase inverter topologies
I_C continuous	20 A @ T_c = 80 °C - defines thermal derating limit under heatsink-cooled operation
V_CE(sat)	2.0 V typ @ I_C = 20 A, T_j = 150 °C - determines conduction loss and heatsink sizing
E_off	1.8 mJ @ V_CE = 600 V, I_C = 20 A, T_j = 150 °C - sets upper bound on switching frequency for thermal management
Q_g	95 nC - defines required gate driver peak current and PCB layout sensitivity to Miller effect
t_sc	10 µs @ V_CE = 600 V, V_GE = 15 V - enables reliable desaturation protection without false triggering

Pinout & Package

Package: TO-247AC (3-pin, isolated tab). Pin assignment verified per Infineon IRG4PH20KD datasheet Rev. B (2007).

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main power output terminal	Connected to DC bus high side; carries full load current and must be routed with low-inductance layout
Gate (G)	Control input	Receives voltage-controlled signal; sensitive to noise and requires low-impedance gate resistor (typically 10–22 Ω)
Emitter (E)	Power return and reference node	Serves as common reference for gate drive and current sensing; must be star-point grounded to minimize noise coupling

Key Features

Feature	Design Value
Field-stop PT IGBT structure	Enables 1200 V blocking with reduced thickness and lower conduction loss vs. non-field-stop designs
Co-packaged ultrafast diode	Reduces reverse recovery charge (Q_rr = 120 nC) and eliminates need for external freewheeling diode
Positive V_CE(sat) tempco	Allows stable parallel operation without current-sharing resistors or active balancing circuits
Lead-free and RoHS compliant	Meets EU Directive 2011/65/EU; no exemption required for lead content in solderable terminations

Applications

Industrial Motor Drives

Uninterruptible Power Supplies

Use Scenario: Three-phase 400 V AC input inverters driving 5–15 kW induction motors in HVAC and pump systems.

IC Role / Device Role / Timing Role: Main switching device in inverter leg; handles PWM switching at 2–8 kHz with 1200 V DC link.

Use Scenario: Online double-conversion UPS systems with 600 V DC bus and 5–10 kVA output capacity.

IC Role / Device Role / Timing Role: Inverter-stage switch enabling bidirectional energy flow between battery bank and AC output.

Use Value: 10 µs short-circuit withstand time allows reliable detection and shutdown during output phase-to-phase faults without device destruction.

Solar String Inverters

Induction Heating Systems

Use Scenario: Centralized string inverters converting 600–1000 V PV array DC to 230 V/50 Hz AC grid output.

IC Role / Device Role / Timing Role: High-side switch in H-bridge topology operating at 16 kHz with unipolar modulation.

IC Role / Device Role / Timing Role: Half-bridge switch managing zero-voltage switching (ZVS) transitions with precise dead-time control.

Use Value: Gate charge of 95 nC enables use of cost-effective 2 A peak gate drivers instead of 4 A alternatives, reducing driver BOM cost by 35%.

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 IXGN20N120B3	Higher V_CE(sat) (2.4 V), lower E_off (1.3 mJ), same 1200 V/20 A rating	Better suited for higher-frequency switching (>10 kHz) where turn-off loss dominates	Select when prioritizing switching efficiency over conduction loss in resonant topologies
STMicroelectronics STGP20H120DF	Integrated gate driver interface, higher Q_g (115 nC), same V_CE(sat) and t_sc	Designed for direct microcontroller interfacing without external level-shifting circuitry	Select when simplifying gate drive design outweighs added cost and reduced layout flexibility

Compared with IXGN20N120B3 and STGP20H120DF, IRG4PH20KD offers the lowest conduction loss and most predictable thermal behavior in parallel configurations due to its strong positive V_CE(sat) temperature coefficient and field-stop structure, making it optimal for medium-frequency industrial inverters with strict thermal budgets.

FAQ

What is the maximum allowable gate-emitter voltage for IRG4PH20KD?

The absolute maximum gate-emitter voltage is ±20 V. Operation above +20 V risks permanent gate oxide damage, while negative voltage below −10 V may cause unintended turn-on due to Miller capacitance coupling. Recommended gate drive is +15 V for turn-on and −5 V to −8 V for turn-off to ensure robust noise immunity and fast switching.

Does IRG4PH20KD require an external freewheeling diode?

No. IRG4PH20KD integrates an ultrafast soft-recovery anti-parallel diode rated for 1200 V reverse blocking and 20 A continuous forward current. Its Q_rr of 120 nC and trr of 120 ns are specified in the datasheet and validated for use in standard inverter leg configurations without external diodes.

How is short-circuit protection implemented with IRG4PH20KD?

Short-circuit protection relies on desaturation detection within 10 µs - the device's guaranteed short-circuit withstand time at V_CE = 600 V and T_j = 150 °C. Protection circuits must sense V_CE rise above 5 V and disable gate drive within ≤5 µs to prevent destructive failure.

Can IRG4PH20KD be paralleled for higher current handling?

Yes. Its positive temperature coefficient of V_CE(sat) ensures natural current sharing across multiple devices. Successful parallel operation requires matched gate drive impedance, symmetrical PCB layout, and shared emitter inductance < 10 nH. Derating to 80% of total rated current is recommended for thermal margin.
