International Rectifier 64-9142PBF

Overview

64-9142PBF from International Rectifier is a P-channel power MOSFET for switching, load-control, and power-conversion circuits supplied in the a package option that should be confirmed before layout release package. The device is intended for discrete power switching where board designers need a defined MOSFET package, gate-control interface, drain-source current path, and thermal path.

For engineers reviewing the 64-9142PBF datasheet, 64-9142PBF pinout, 64-9142PBF application, or 64-9142PBF equivalent, this device is commonly used in P-channel high-side switching, reverse-polarity protection, battery-connected load control, power-path management, and legacy board replacement. Selection should focus on channel polarity, drain-source voltage, continuous and pulsed current, RDS(on), gate charge, body-diode behavior, package thermal resistance, and footprint compatibility.

Technical Context

In circuit use, 64-9142PBF is typically applied where P-channel gate-drive polarity simplifies high-side switching, reverse-battery protection, or load-disconnect control.

The design must account for source-referenced gate drive, maximum VGS rating, body-diode direction, and the higher conduction-loss sensitivity often associated with P-channel MOSFET selections.

The package pending verification package should be matched to copper area or heatsink design so that RDS(on) rise at temperature does not reduce load-current margin.

Key Specifications

Pinout & Package

The 64-9142PBF pinout should be checked together with the confirmed package 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. Exact package should be confirmed from the orderable documentation before PCB release.

Key Features

• 64-9142PBF is a P-channel power MOSFET for power switching, load control, and converter-stage use.
• package pending verification package affects footprint compatibility, thermal impedance, and assembly method.
• Low RDS(on), gate charge, and package thermal resistance are the main parameters for efficiency and temperature rise.
• Body-diode behavior and avalanche capability support inductive-load and synchronous-switching design checks.
• Can be driven from an external gate driver, controller, or logic stage when gate-drive voltage and timing are validated.
• Suitable for BOM continuation and replacement projects when footprint, pinout, and electrical ratings match the original board.

Applications

Equivalent & Alternatives

When evaluating 64-9142PBF 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, 64-9142PBF should remain the preferred sourcing reference when the existing BOM, PCB footprint, and qualification documentation require the exact International Rectifier orderable device.

Quality

64-9142PBF 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 64-9142PBF 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

64-9142PBF 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 64-9142PBF 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.
