Why Choose onsemi High Voltage MOSFETs?
onsemi high voltage MOSFETs provide a practical selection for designers who need to balance efficiency, thermal performance, package size and switching behavior. For higher current power stages, NTH4LN019N65S3H offers a 650 V rating, 75 A current capability and very low 19.3 mΩ maximum RDS(on). For applications requiring a standard TO-247 package, FCH040N65S3 provides a 650 V, 65 A option with 40 mΩ maximum RDS(on).
For power supply platforms that need a TO-220 package, FCP067N65S3 and NTP067N65S3H provide 650 V options with 67 mΩ maximum RDS(on). NTHL082N65S3F is suitable for designs where body diode performance is important, such as resonant or high-speed switching circuits.
Typical Applications
onsemi high voltage MOSFETs can be used in:
Power factor correction circuits
Server and telecom power supplies
EV charger power stages
Solar inverter and UPS systems
Industrial power supplies
LED lighting and ballast designs
High-frequency switching converters
Selection Guide
When selecting an onsemi high voltage MOSFET, the first step is to match the required voltage rating and current rating. For higher power systems, lower RDS(on) models such as NTH4LN019N65S3H and FCH040N65S3 help reduce conduction loss. For compact or cost-sensitive designs, TO-220 models such as FCP067N65S3 and NTP067N65S3H may be easier to use. For circuits where reverse recovery behavior matters, FRFET options such as NTHL082N65S3F can be considered.
