APT5F100K is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists Microsemi Corporation. Its product description is MOSFET N-CH 1000V 5A TO220. Review the specifications below when checking this part for your BOM.
The APT5F100K is a 1000V, 5A N-channel FREDFET in a TO-220 package. It features a maximum drain-source on-resistance of 2.8Ω at VGS=10V and ID=3A. The device supports a continuous drain current of 5A at TC=25°C and a pulsed drain current of 20A. Key dynamic characteristics include a reverse recovery time (trr) of ≤155ns and a peak recovery dv/dt of 43V/ns. It operates within a junction temperature range of -55°C to 150°C.
Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact electrical tolerances and packaging variations. Ensure the component meets RoHS compliance requirements if applicable to your design specifications. Cross-reference the datasheet revision date to confirm the validity of the thermal and switching parameters provided.
Select this component for high-voltage switch-mode power applications requiring fast switching and low EMI. Consider the 2.8Ω maximum RDS(on) for conduction loss calculations at 3A. Evaluate the thermal impedance characteristics for heatsinking requirements in TO-220 packages. Verify compatibility with ZVS topologies due to the optimized body diode recovery characteristics.
This part belongs to Microsemi's POWER MOS 8 family of high-speed, high-voltage N-channel switch-mode power MOSFETs. The FREDFET variant specifically targets applications where body diode performance is critical, such as synchronous rectification or hard-switched topologies requiring robust reverse recovery behavior.
