Single FETs, MOSFETs Procurement Notes

Verify the manufacturer designation carefully, as this component was originally developed by Advanced Power Technology (APT) and later acquired by Microsemi, which is now part of Microchip Technology. Confirm the specific package variant (e.g., TO-247 or D3PAK) matches your PCB footprint requirements. Ensure RoHS compliance status aligns with your manufacturing standards. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.

Single FETs, MOSFETs Selection Notes

Select this component when designing circuits requiring robust high-voltage handling up to 800 V combined with moderate current capacity around 18 A. The MOS8 technology offers a balance of low on-resistance and fast switching speeds, making it suitable for efficient power conversion. Consider thermal management solutions given the 625 W power dissipation rating, and ensure gate drive voltages remain within the specified ±30 V limits to prevent device damage.
