International Rectifier AUIRLR024N

Overview

AUIRLR024N from International Rectifier is an Automotive N-channel HEXFET MOSFET supplied in the TO-252-3, DPAK (2 Leads + Tab), SC-63 package. The device is used as a n-channel. switching element where drain-source voltage rating, conduction loss, gate charge, avalanche behavior, and package thermal resistance must be matched to the circuit.

For engineers reviewing the AUIRLR024N datasheet, AUIRLR024N pinout, AUIRLR024N application, or AUIRLR024N equivalent, this device is commonly used in power load switching, dc-dc converter stages, motor and inductive load control, and repair and bom continuity designs. For engineers comparing AUIRLR024N against other MOSFETs, the useful checks are voltage rating: 55 V., current rating: 17 A case class., RDS(on): 65 mΩ max at 10 A, 10 V. The bulk supply entry and package style should be confirmed before using it as a direct BOM replacement.

Technical Context

In a switching circuit, AUIRLR024N may serve as a low-side switch, high-side device, synchronous rectifier, motor-control transistor, battery-path switch, or converter power device depending on polarity and topology. The package tab or exposed pad normally carries the drain connection and dominates the thermal path.

DPAK / TO-252 surface-mount package for medium-current switching with PCB copper thermal spreading. Gate-drive selection should account for total gate charge, Miller plateau behavior, switching frequency, and allowable VGS range; using only RDS(on) to compare MOSFETs can lead to excessive switching loss or poor transient behavior.

Thermal validation is required at the final load current because rated current values assume defined case or board conditions. For inductive loads, the avalanche rating, body-diode recovery, clamp network, and safe operating area should be checked with the actual load profile.

Key Specifications

Pinout & Package

The AUIRLR024N pinout must be reviewed from the exact package drawing because terminal function, thermal path, and mechanical footprint are linked in this product family. TO-252-3, DPAK (2 Leads + Tab), SC-63 package information and Bulk packaging for this line.

For PCB design, use the package drawing and confirm copper area, soldering method, creepage or clearance where applicable, and the final orderable suffix before layout or replacement approval. DPAK / TO-252 surface-mount package for medium-current switching with PCB copper thermal spreading.

Applications

Equivalent & Alternatives

When evaluating AUIRLR024N equivalent devices, engineers should compare only specific orderable alternatives and should verify package footprint, pinout, electrical ratings, thermal data, qualification status, and suffix or packing requirements before substitution.

Compared with related alternatives, AUIRLR024N should remain the preferred sourcing reference when the existing BOM, PCB footprint, and qualification documentation require the exact International Rectifier orderable device.

Quality

AUIRLR024N 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 AUIRLR024N is used in power switching and converter circuits, final validation should include the actual PCB footprint, thermal path, electrical stress, operating temperature, and fault-condition behavior. Traceable sourcing helps reduce counterfeit risk and supports repeatable performance in production, repair, and maintenance programs.

Availability

AUIRLR024N available at Aetrix Electronics and suitable for power switching and converter circuits requiring stable component supply, package matching, 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 AUIRLR024N ordering line should be reviewed with the relevant International Rectifier legacy technical documentation and Infineon supply-chain references where available. This is especially important for legacy MOSFETs, IRAM modules, PV relay products, and automotive AUIR power devices.

FAQ

What is AUIRLR024N used for?

AUIRLR024N is used in power switching and converter circuits. The exact application depends on the technical documentation electrical ratings, package, pinout, and thermal capability.

Where can I find the AUIRLR024N technical documentation?

The AUIRLR024N technical documentation should be obtained from International Rectifier / Infineon documentation or an authorized technical documentation source. It should be used to confirm ratings, package information, pinout, thermal data, and test conditions.

What should be considered in AUIRLR024N pinout design?

Pinout design should confirm the package drawing, terminal functions, thermal path, high-current routing or isolation spacing, and whether the orderable suffix changes package or packing details.

Can AUIRLR024N be used as a direct replacement?

AUIRLR024N can be used as a direct replacement only when the package footprint, pinout, electrical ratings, thermal behavior, and qualification status match the original design.

What are common AUIRLR024N equivalent solutions?

Equivalent solutions should be limited to specific orderable devices with verified technical documents. Suffix variants may differ in package, reel orientation, lead finish, qualification, or manufacturing status.
