HUF75343S3ST

Single FETs, MOSFETs Overview

The HUF75343S3ST is an N-Channel UltraFET Power MOSFET manufactured by onsemi, formerly Fairchild Semiconductor. It utilizes the TO-263AB (D2PAK) surface-mount package with a tape-and-reel suffix 'T'. The device features a drain-to-source voltage of 55 V and a continuous drain current of 75 A at 25°C case temperature. The maximum drain-to-source on-resistance is 0.009 Ω at VGS = 10V and ID = 75A. It supports a junction temperature range from -55°C to +175°C and offers thermal impedance characteristics suitable for high-power switching applications.

Single FETs, MOSFETs Feature Summary

Manufactured using the UltraFET process technology to achieve low on-resistance per silicon area.
Capable of withstanding high energy in avalanche mode.
Exhibits very low reverse recovery time and stored charge in the body diode.
Includes simulation models for PSPICE and SABER.

Single FETs, MOSFETs Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for lifecycle changes as this part may be discontinued. Ensure proper handling for ESD-sensitive components during storage and assembly.

Single FETs, MOSFETs Selection Notes

Select based on required voltage rating and current capacity. Consider thermal management requirements given the power dissipation limits. Verify gate drive compatibility with the specified threshold voltage. Evaluate PCB layout constraints for the TO-263AB package.

Single FETs, MOSFETs Part Context

This component belongs to the HUF75343 series of N-Channel Power MOSFETs. Other variants include HUF75343G3 (TO-247), HUF75343P3 (TO-220AB), and HUF75343S3 (TO-262AA). The S3ST variant specifically denotes the D2PAK package in tape-and-reel format.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes within the same family include HUF75343S3 (same package, different reel option). Cross-package replacements like HUF75343P3 require mechanical adaptation. Verify pinout compatibility and thermal resistance differences when substituting.
