International Rectifier IRG7PSH50UDPBF

Overview

IRG7PSH50UDPBF from International Rectifier is an IGBT power transistor with co-packaged diode support for inverter, motor-drive, and power-conversion switching supplied in the TO-274AA package. It is used where a gate-controlled high-voltage power switch is required for inverter bridges, motor-drive stages, braking circuits, or industrial power-conversion hardware.

For engineers reviewing the IRG7PSH50UDPBF datasheet, IRG7PSH50UDPBF pinout, IRG7PSH50UDPBF application, or IRG7PSH50UDPBF equivalent, this device is commonly used in IGBT inverter stages, motor-control output sections, power-conversion repair boards, and legacy International Rectifier designs. Selection should focus on collector-emitter voltage rating, collector current, saturation voltage, switching energy, diode behavior, package thermal path, and gate-drive limits.

Technical Context

In circuit use, IRG7PSH50UDPBF operates as a gate-controlled IGBT power switch. The gate driver must be referenced correctly to the emitter, and the collector current path should be kept short to reduce overshoot during fast switching.

The IGBT voltage class must be matched to the DC-link requirement positioning makes DC-link voltage, switching energy, heatsink temperature, and collector-current waveform important design checks. In motor drives and inverter circuits, conduction loss and turn-off loss should be evaluated under the actual PWM frequency and cooling condition.

The TO-274AA package affects how heat leaves the device and how the collector or power tab is connected to the layout. Mechanical mounting, creepage distance, snubber placement, and gate-loop inductance are practical factors in reliable IGBT operation.

Key Specifications

Pinout & Package

The IRG7PSH50UDPBF pinout should be checked together with the TO-274AA outline, because terminal arrangement and thermal connection affect layout, replacement approval, and assembly method.

For PCB design, keep the high-current power path short, route the gate or control line away from noisy switching nodes, and size copper or heatsinking for the real load current and duty cycle. Package and footprint should be confirmed against the board layout and assembly process.

Key Features

• IRG7PSH50UDPBF is an IGBT switching device for inverter, motor-drive, and power-conversion stages.
• TO-274AA package supports thermal coupling to PCB copper or heatsink hardware depending on package style.
• Gate-controlled bipolar conduction supports efficient switching at higher bus voltages than typical low-voltage MOSFET stages.
• Collector-emitter voltage rating, saturation voltage, and switching energy are the main design parameters for loss calculation.
• Co-pack diode or diode-related suffix behavior should be evaluated for freewheeling and reverse-recovery loss where applicable.
• Suitable for designs requiring controlled turn-on, controlled turn-off, short current-loop layout, and thermal-margin verification.

Applications

Equivalent & Alternatives

When evaluating IRG7PSH50UDPBF equivalent devices, engineers should compare only specific orderable part numbers and verify package footprint, pinout, voltage rating, current rating, thermal resistance, switching behavior, qualification status, and suffix or packing requirements before substitution.

Compared with related alternatives, IRG7PSH50UDPBF should remain the preferred sourcing reference when the existing BOM, PCB footprint, and qualification documentation require the exact International Rectifier orderable device.

Quality

IRG7PSH50UDPBF should be sourced as original International Rectifier / Infineon inventory through traceable and controlled supply channels. Quality verification may include package inspection, top-mark validation, label and lot review, solderability inspection, moisture-sensitivity handling review, and electrical screening according to the target production requirement.

Because IRG7PSH50UDPBF is used in power switching circuits, final validation should include the actual PCB footprint, thermal path, electrical stress, operating temperature, switching frequency, and fault-condition behavior. Traceable sourcing helps reduce counterfeit risk and supports repeatable performance in production, repair, and maintenance programs.

Availability

IRG7PSH50UDPBF available at Aetrix Electronics and suitable for power switching, power-conversion, motor-control, load-driver, repair, and BOM-continuity applications requiring stable component supply and controlled replacement planning.

Supply support may include scheduled delivery planning, volume procurement support, BOM continuity assistance, traceable sourcing management, and long-term availability support for OEM manufacturers, repair programs, and electronics production teams.

For production or repair deployment, confirming package type, orderable suffix, lifecycle status, environmental requirement, electrical rating, thermal condition, and sourcing continuity helps reduce procurement risk and improve manufacturing stability.

Manufacturer

International Rectifier was a semiconductor manufacturer known for power MOSFETs, IGBTs, gate drivers, power-management ICs, intelligent power switches, photovoltaic relays, and power modules. International Rectifier products became part of Infineon Technologies' power semiconductor portfolio after the acquisition of International Rectifier.

The IRG7PSH50UDPBF ordering line should be reviewed with the relevant International Rectifier legacy product family and current Infineon supply-chain references where available. This is especially important for legacy MOSFETs, IGBT devices, power modules, and automotive AUIR power devices.
