APT58M80J

Single FETs, MOSFETs Overview

The APT58M80J is a screw-mount N-channel power MOSFET module from the POWER MOS 8 series, manufactured by Microchip Technology. It features an ISOTOP package (SOT-227-4/miniBLOC) designed for high-power applications. The device supports a drain-source voltage of 800 V and a continuous drain current of 58 A at case temperature. It dissipates up to 543 W of power at case temperature and operates within a junction temperature range of -55°C to +150°C.

Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix against the official Microchip datasheet to ensure correct packaging and temperature grade. Confirm that the ISOTOP mounting surface preparation meets the manufacturer's torque and thermal interface material specifications. Check for recent Product Change Notifications regarding pinout or material composition updates before finalizing procurement orders.

Single FETs, MOSFETs Selection Notes

Select this component when an 800 V rating and 58 A current capacity are required in a screw-mount configuration. The ISOTOP package eliminates the need for separate insulators, simplifying mechanical assembly. Ensure the application's thermal management system can handle the 543 W dissipation rating at the specified case temperature to maintain reliability within the -55°C to +150°C operating range.

Single FETs, MOSFETs Part Context

This part belongs to the APT series of Power MOSFET modules, which utilize advanced trench gate technology. The 'J' suffix typically denotes a specific packaging or tape-and-reel variant, though standard distribution often uses tubes. It serves as a high-voltage alternative to lower-rated devices in the same family, offering higher blocking voltage while maintaining competitive on-state resistance characteristics.

Single FETs, MOSFETs Replacement Considerations

Direct replacements include APT58M50J (500 V rating) if voltage headroom allows, or APT32M80J (lower current). Verify pin compatibility and thermal resistance values when substituting.
