International Rectifier AUIRF7799L2TR

Overview

AUIRF7799L2TR from International Rectifier is a automotive-qualified N-channel power MOSFET in DirectFET package for low-inductance high-current switching supplied in the DirectFET™ Isometric L8 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 AUIRF7799L2TR datasheet, AUIRF7799L2TR pinout, AUIRF7799L2TR application, or AUIRF7799L2TR equivalent, this device is commonly used in high-current DC-DC converters, synchronous rectification, compact load switching, low-inductance power stages, and high-density board layouts. 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, AUIRF7799L2TR is placed close to the inductor, power stage, or load path so that the DirectFET package can reduce package inductance and switching-loop area.

Gate charge, output capacitance, source inductance, and reverse-recovery behavior determine whether the MOSFET can meet efficiency and EMI targets at the selected switching frequency.

The DirectFET footprint should be checked with the exact land pattern, soldering process, and top-side or bottom-side thermal path because DirectFET assembly differs from conventional tabbed power packages.

Key Specifications

Pinout & Package

The AUIRF7799L2TR pinout should be checked together with the DirectFET™ Isometric L8 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. DirectFET low-profile package with short current paths and low package inductance for compact high-current boards.

Key Features

• AUIRF7799L2TR is a N-channel power MOSFET for power switching, load control, and converter-stage use.
• DirectFET 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 AUIRF7799L2TR 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, AUIRF7799L2TR should remain the preferred sourcing reference when the existing BOM, PCB footprint, and qualification documentation require the exact International Rectifier orderable device.

Quality

AUIRF7799L2TR 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 AUIRF7799L2TR 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

AUIRF7799L2TR 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 AUIRF7799L2TR 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.
