Single FETs, MOSFETs datasheet and documents for AUIRFZ46NL

AUIRFZ46NL

Single FETs, MOSFETs Overview

The AUIRFZ46NL is an automotive-grade single N-channel power MOSFET manufactured by Infineon Technologies. It utilizes advanced planar HEXFET technology to achieve low on-resistance and fast switching speeds. The device is housed in a TO-262 (I2PAK) through-hole package, rated for a maximum drain-source voltage of 55V and a continuous drain current of 53A at 25°C case temperature. Key electrical parameters include a maximum static drain-to-source on-resistance of 16.5mΩ at VGS=10V, a gate threshold voltage range of 2.0V to 4.0V, and a total gate charge of 72nC. It supports a junction temperature up to 175°C and features fully avalanche-rated capabilities.

Single FETs, MOSFETs Feature Summary

Automotive qualified with ruggedized design suitable for demanding environments
Advanced planar technology providing low on-resistance per silicon area
Fast switching characteristics combined with high thermal efficiency
Fully avalanche rated allowing repetitive avalanche operation up to Tjmax

Single FETs, MOSFETs Applications

Automotive motor control systems
Automotive switch mode power supplies (SMPS)
General purpose automotive power switching applications

Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix to confirm the package type and packing quantity. The standard tube packaging contains 50 units per tube. Confirm RoHS compliance status and ensure the component meets the required automotive qualification standards before integration into final designs.

Single FETs, MOSFETs Selection Notes

Select this component when an automotive-grade N-channel MOSFET with a 55V rating and high current capability is required. Ensure the application operates within the specified 175°C junction temperature limit and accounts for the package-limited continuous drain current of 39A under typical board-mounted conditions.

Single FETs, MOSFETs Part Context

This part belongs to the IRFZ46 series of HEXFET power MOSFETs. The 'AU' prefix indicates that the device follows automotive industry requirements regarding product discontinuance and process change notification. It is distinct from industrial variants by its adherence to specific automotive qualification protocols.

Single FETs, MOSFETs Replacement Considerations

Direct replacements include the IRFZ46NL for non-automotive versions or the AUIRFZ46NS which shares identical electrical specifications but utilizes a D2Pak surface-mount package instead of the TO-262 leaded form factor.
