International Rectifier AUIRLS3034-7TRL

Overview

AUIRLS3034-7TRL from International Rectifier is a automotive-qualified logic-level N-channel power MOSFET for switching, load-control, and power-conversion circuits supplied in the TO-263-8, D2PAK (7 Leads + Tab), TO-263CA 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 AUIRLS3034-7TRL datasheet, AUIRLS3034-7TRL pinout, AUIRLS3034-7TRL application, or AUIRLS3034-7TRL equivalent, this device is commonly used in automotive load switching, motor control, relay and solenoid switching, DC-DC converter stages, battery power paths, and legacy power-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, AUIRLS3034-7TRL supports lower-voltage gate-drive control than standard gate-drive MOSFET families, which is useful when the control signal comes from a microcontroller, low-voltage driver, or logic rail.

Logic-level operation does not remove the need to review RDS(on) at the actual gate voltage. Thermal rise, pulsed current, and avalanche stress still determine safe load-current capability.

The D²Pak / TO-263 package affects both footprint compatibility and heat spreading, so the same electrical die may behave differently in DPAK, D²Pak, IPAK, I²Pak, TO-220, or DirectFET versions.

Key Specifications

Pinout & Package

The AUIRLS3034-7TRL pinout should be checked together with the TO-263-8, D2PAK (7 Leads + Tab), TO-263CA 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. D²Pak surface-mount power package using the drain or collector tab for PCB copper heat spreading.

Key Features

• AUIRLS3034-7TRL is a N-channel power MOSFET for power switching, load control, and converter-stage use.
• D²Pak / TO-263 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 AUIRLS3034-7TRL 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, AUIRLS3034-7TRL should remain the preferred sourcing reference when the existing BOM, PCB footprint, and qualification documentation require the exact International Rectifier orderable device.

Quality

AUIRLS3034-7TRL 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 AUIRLS3034-7TRL 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

AUIRLS3034-7TRL 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 AUIRLS3034-7TRL 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.
