International Rectifier AUIPS1011RTRL

Overview

AUIPS1011RTRL from International Rectifier is a automotive-grade intelligent power low-side switch designed for protected switching of resistive and inductive loads. The device combines a power MOSFET, gate driver, over-current shutdown, over-temperature shutdown, ESD protection, and drain-to-source active clamp in a three-terminal power-switch structure.

As an orderable version of the AUIPS1011 family, AUIPS1011RTRL is associated with the D-Pak / TO-252 surface-mount package associated with the AUIPS1011R variant. For engineers reviewing the AUIPS1011RTRL datasheet, AUIPS1011RTRL pinout, AUIPS1011RTRL application, or AUIPS1011RTRL equivalent, this device is mainly used where a logic-level control signal must switch a load return path while adding integrated protection against short-circuit, overheating, and inductive-load turn-off stress.

Technical Context

In a typical low-side load-driver circuit, AUIPS1011RTRL is placed between the load and ground. The load connects to the positive supply, while the drain terminal connects to the low side of the load and the source terminal returns to system ground.

The product summary specifies 13 mΩ maximum RDS(on), 39 V active clamp voltage, and 85 A typical shutdown current, giving the designer a defined protected-switch behavior rather than an unprotected discrete MOSFET. During an overload or excessive junction-temperature condition, the internal driver turns the MOSFET off and the switch is restarted by cycling the input signal.

The active clamp function is important for relay coils, solenoids, actuators, and other inductive loads. During turn-off, the device clamps the drain-to-source voltage and helps handle stored magnetic energy without relying only on external flyback components.

Key Specifications

Pinout & Package

The AUIPS1011RTRL pinout follows the three-terminal protected switch format used by the AUIPS1011 family. The control input drives the internal gate-driver circuit, the drain connects to the switched load node, and the source provides the power return reference.

For PCB layout, the drain copper and package tab area should be sized for load current and heat spreading. The source path should be kept low impedance, and the input trace should be separated from high-current switching nodes to reduce noise coupling into the control signal.

Key Features

• Protected low-side switch architecture combining a power MOSFET and gate driver.
• Integrated over-current shutdown for overload and short-circuit protection.
• Integrated over-temperature shutdown for thermal fault protection.
• Drain-to-source active clamp helps absorb inductive-load energy during turn-off.
• Low-current logic-level input simplifies control from microcontrollers or logic devices.
• ESD protection improves robustness in harsh electrical environments.
• Three-terminal switch structure simplifies replacement of discrete MOSFET driver circuits.
• Suitable for resistive and inductive loads when current, energy, and thermal limits are verified.

Applications

Equivalent & Alternatives

When evaluating AUIPS1011RTRL equivalent devices, engineers should compare package footprint, tab connection, RDS(on), clamp voltage, shutdown current, thermal resistance, input threshold, diagnostic method, switching timing, and load energy profile.

Compared with a standard MOSFET, AUIPS1011RTRL provides an integrated protection strategy for low-side load switching. Package-specific alternatives within the same family are usually the closest options, while other protected switches require electrical, thermal, and PCB-footprint verification.

Quality

AUIPS1011RTRL should be sourced as original International Rectifier / Infineon legacy power-switch components through traceable and controlled channels. Quality checks may include package inspection, top-mark validation, terminal inspection, moisture-control review, solderability testing, and incoming electrical screening.

Because the device switches load current and absorbs inductive energy, PCB copper area, thermal resistance, clamp energy, load duty cycle, source grounding, and reset behavior after protection events should be verified in the final equipment.

Availability

AUIPS1011RTRL available at Aetrix Electronics and suitable for protected low-side load switching, relay and solenoid control, actuator outputs, lamp switching, and industrial or automotive power-control circuits requiring stable component supply and replacement support.

Supply support may include scheduled delivery planning, volume procurement support, BOM continuity assistance, traceable sourcing management, and long-term availability support for OEM manufacturers, industrial maintenance teams, repair programs, and electronics production projects.

For production or repair deployment, confirming package type, suffix, lifecycle status, load current, thermal condition, inductive energy, and sourcing continuity helps reduce procurement risk.

Manufacturer

International Rectifier was a power semiconductor manufacturer known for MOSFETs, IGBTs, gate drivers, and power-management devices. International Rectifier product lines later became part of Infineon Technologies' power semiconductor portfolio.

The AUIPS1011 family belongs to the protected power switch category and is intended for robust low-side load switching in harsh electrical environments where current shutdown, thermal shutdown, and inductive-load clamp behavior are required.
