Product details

Overview

AUIRFP1405-203 from International Rectifier is a automotive-qualified N-channel power MOSFET for switching, load-control, and power-conversion circuits supplied in the a package option that should be confirmed before layout release 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 AUIRFP1405-203 datasheet, AUIRFP1405-203 pinout, AUIRFP1405-203 application, or AUIRFP1405-203 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, AUIRFP1405-203 serves as the main discrete switching element between the supply, load, or converter node and the power return or power rail.

The gate driver should be selected from the required gate voltage, total gate charge, switching speed, and EMI target. RDS(on), pulsed current, avalanche capability, and body-diode recovery define practical load and converter limits.

The package pending verification package determines the board footprint, heat-spreading path, and current terminal arrangement. For replacement work, the package and pinout should be confirmed before assuming interchangeability with another IRF or AUIRF suffix.

Key Specifications

Parameter	Value and Actual Design Meaning
Device Type	automotive-qualified N-channel power MOSFET for switching, load-control, and power-conversion circuits.
Package	Package to be confirmed; Exact package should be confirmed from the orderable documentation before PCB release.
Channel / Polarity	N-channel power MOSFET; polarity and body-diode orientation must match the original power stage.
Gate-Drive Class	Gate-drive voltage should be selected from the RDS(on) test condition and switching-loss target.
On-Resistance Review	RDS(on), package temperature rise, and PCB copper area define conduction loss under continuous load current.
Switching Parameter Review	Gate charge, input capacitance, output capacitance, and reverse-recovery behavior affect driver selection and switching frequency.
Avalanche / Inductive Load Review	Single-pulse avalanche rating, repetitive stress, and body-diode use should be checked for inductive or motor-load circuits.
Thermal Design	package pending verification thermal path should be evaluated with the actual copper area, airflow, heatsink, and duty cycle.
Automotive Usage	AUIR/AUI-prefixed device line is intended for automotive-oriented power designs where qualification and change control are important.

Pinout & Package

The AUIRFP1405-203 pinout should be checked together with the confirmed package 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. Exact package should be confirmed from the orderable documentation before PCB release.

Pin / Function	PCB Design and Circuit Role
Gate	MOSFET control terminal; selected drive voltage, gate resistance, and driver strength affect switching loss and EMI.
Drain / Tab	Main power terminal tied to the package tab in many power packages; use adequate copper area or heatsinking for heat spreading.
Source	Power return terminal; route with low resistance and low inductance to reduce loss and switching overshoot.
Package Body	package pending verification package: Exact package should be confirmed from the orderable documentation before PCB release.

Key Features

AUIRFP1405-203 is a N-channel power MOSFET for power switching, load control, and converter-stage use.
package pending verification package affects footprint compatibility, thermal impedance, and assembly method.
