International Rectifier AUIPS1011R

Overview

AUIPS1011R from International Rectifier is an Automotive-grade intelligent power low-side switch with integrated MOSFET driver and protection functions supplied in the TO-252-3, DPAK (2 Leads + Tab), SC-63 package. Unlike a bare MOSFET, it combines the power switch with fault protection functions such as over-current shutdown, over-temperature shutdown, ESD protection, and active clamp behavior for inductive-load turn-off.

For engineers reviewing the AUIPS1011R datasheet, AUIPS1011R pinout, AUIPS1011R application, or AUIPS1011R equivalent, this device is commonly used in automotive low-side load switching, relay, solenoid & actuator control, protected output channels, and legacy board replacement designs. The device is selected for low-side load paths where the load is tied to the positive supply and AUIPS1011R controls the ground return. RDS(on) is 13 mΩ maximum, defining conduction loss and voltage drop under load current.

Technical Context

In circuit use, AUIPS1011R sits between the load and system ground. The input pin receives a logic-level command while the drain carries load current, so the drain copper area, source return, and input routing should be designed separately rather than treated as a simple signal device.

The protection behavior is a main selection point. During overload or short-circuit conditions, the internal switch shuts down instead of relying only on an external fuse; during inductive turn-off, the active clamp path handles stored magnetic energy within the rated clamp and thermal limits.

For production design, AUIPS1011R should be checked for RDS(on), current shutdown threshold, clamp voltage, thermal shutdown behavior, junction-temperature rise, and reset behavior after a latched fault. These details determine whether it can replace a discrete MOSFET plus external protection network.

Key Specifications

Pinout & Package

The AUIPS1011R 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.

Key Features

• Automotive-grade intelligent power low-side switch with integrated MOSFET driver and protection functions for protected low-side load control.
• Integrated MOSFET switching path reduces external protection circuitry.
• Over-current shutdown and thermal shutdown support fault-tolerant output-channel design.
• Active clamp behavior supports inductive-load turn-off within rated clamp and thermal limits.
• TO-252-3, DPAK (2 Leads + Tab), SC-63 package affects thermal spreading, footprint compatibility, and assembly process.
• Input-controlled operation supports MCU or logic-driven load switching.

Applications

Equivalent & Alternatives

When evaluating AUIPS1011R 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, AUIPS1011R should remain the preferred sourcing reference when the existing BOM, PCB footprint, and qualification documentation require the exact International Rectifier orderable device.

Quality

AUIPS1011R 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 AUIPS1011R is used in protected low-side switching 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

AUIPS1011R available at Aetrix Electronics and suitable for protected low-side switching 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 AUIPS1011R 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 AUIPS1011R used for?

AUIPS1011R is used in protected low-side switching circuits. The exact application depends on the technical documentation electrical ratings, package, pinout, and thermal capability.

Where can I find the AUIPS1011R technical documentation?

The AUIPS1011R 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 AUIPS1011R 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 AUIPS1011R be used as a direct replacement?

AUIPS1011R 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 AUIPS1011R 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.
