Product details

Overview

AUIRF1405-INF from Infineon Technologies (formerly International Rectifier) is an automotive-grade N-channel HEXFET® Power MOSFET in TO-220AB package, rated for 55 V V(BR)DSS, 4.6 mΩ typ. RDS(on), 169 A silicon-limited continuous drain current at TC = 25°C, and qualified to AEC-Q101. It serves as a high-efficiency main power switch in 12 V automotive DC-DC converters, motor control inverters, and battery disconnect circuits.

For engineers reviewing the AUIRF1405-INF datasheet, AUIRF1405-INF pinout, AUIRF1405-INF application, or AUIRF1405-INF equivalent, key selection criteria include its 0.45 °C/W RθJC thermal resistance, 170 nC typical total gate charge, 101 A unclamped inductive avalanche rating, and body diode recovery time of 88 ns - all critical for hard-switched automotive power stages requiring ruggedness and low conduction loss.

Technical Context

This MOSFET employs stripe planar silicon technology optimized for low on-resistance per die area and fast switching. Its gate threshold voltage (2.0–4.0 V) enables robust 3.3 V/5 V logic-level drive compatibility when used with appropriate gate drivers, while the 62 nH internal drain inductance and 1210 pF Coss (at VDS = 25 V) directly impact turn-off energy and EMI behavior in high-frequency PWM operation.

The device's thermal design is anchored by junction-to-case thermal resistance of 0.45 °C/W and a maximum operating junction temperature of 175 °C. Its repetitive avalanche capability (EAR = 5.0 mJ at TJ = 25 °C) and single-pulse avalanche energy (EAS = 680 mJ) are validated under defined test conditions (L = 0.11 mH, RG = 25 Ω, IAS = 101 A), supporting fault-tolerant designs in automotive load dump and inductive kick scenarios.

Key Specifications

ParameterValue and Actual Design Meaning
V(BR)DSS55 V - Withstands up to 55 V drain-source blocking voltage before avalanche onset; suitable for 12 V automotive systems with transient overvoltage margin.
RDS(on) typ.4.6 mΩ - Enables <1 W conduction loss at 100 A drain current, reducing heatsink requirements in high-current switching nodes.
ID (Silicon Limited)169 A @ TC = 25°C - Maximum continuous current determined by silicon thermal limits; derates to 118 A at TC = 100°C.
Qg typ.170 nC - Gate drive energy requirement dictates driver strength needed for <130 ns turn-off delay and 110 ns fall time at 101 A.
trr / Qrr88 ns / 250 nC - Body diode reverse recovery performance impacts shoot-through risk and switching loss in synchronous rectification or H-bridge freewheeling.
RθJC0.45 °C/W - Enables direct mounting to heatsinks with predictable thermal rise; 100 W power dissipation yields ~45 °C junction-to-case delta.
EAS680 mJ - Single-pulse avalanche energy rating supports reliable operation during inductive load interruption without external snubbers.

Pinout & Package

Package: TO-220AB - Through-hole, single-ended heat-transfer package with isolated tab (drain-connected), rated for industrial and automotive mounting torque (10 lbf·in / 1.1 N·m).

Pin/TerminalCircuit RoleDesign Meaning
Drain (Tab)Main high-side current path and thermal interfaceElectrically connected to metal tab; must be electrically isolated from heatsink unless system ground reference permits; primary heat conduction path.
SourcePower return node and reference for gate driveLow-inductance source connection critical for stable gate control; internal LS = 7.5 nH affects switching waveform fidelity.
GateControl terminal for channel modulationHigh-impedance input requiring <200 nA leakage compliance; Miller charge Qgd = 62 nC dominates turn-off timing and dV/dt immunity.

FAQ

Is AUIRF1405-INF compatible with standard TO-220 heatsinks?

Yes - the AUIRF1405-INF uses the industry-standard TO-220AB package with an isolated metal tab (drain-connected). It is mechanically and thermally compatible with common TO-220 heatsinks when mounted using the specified 10 lbf·in (1.1 N·m) torque and electrically insulating hardware. Thermal performance assumes flat, greased interface (RθCS = 0.50 °C/W).

What gate drive voltage is required for full enhancement?

The AUIRF1405-INF achieves its specified 4.6 mΩ RDS(on) at VGS = 10 V. While it begins conducting above VGS(th) = 2.0 V, full enhancement and minimal on-resistance require ≥10 V gate drive. For 3.3 V microcontroller interfaces, a gate driver IC (e.g., Infineon 1EDN7512) is necessary to ensure reliable saturation and avoid thermal runaway.

Does AUIRF1405-INF support paralleling for higher current?

Yes - its positive RDS(on) temperature coefficient (0.057 V/°C) enables inherently stable current sharing when multiple devices are paralleled. However, layout symmetry (matched gate and source inductance), individual gate resistors (≥10 Ω), and thermal coupling must be carefully implemented to prevent dynamic imbalance during switching transitions.

How does its body diode performance compare to discrete Schottky diodes?

The integrated body diode has VSD = 1.3 V and trr = 88 ns - higher forward drop than Schottky diodes but significantly faster recovery than standard PN diodes. It is suitable for freewheeling in medium-frequency (<100 kHz) automotive inverters but not for ultra-low-loss synchronous rectification where Schottky or GaN-based solutions offer superior VF and Qrr trade-offs.
