BFL4001-1EX is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists onsemi. Its product description is MOSFET N-CH 900V 6.5A TO220-3 FP. Review the specifications below when checking this part for your BOM.
The BFL4001-1EX is an N-channel MOSFET from onsemi, designed for high-voltage switching applications. It features a drain-source voltage (Vdss) of 900 V and a continuous drain current (Id) of 6.5 A at ambient temperature. The device operates with a gate drive voltage of 10 V and exhibits a maximum on-resistance (Rds(on)) of 2.7 ohms when tested at 3.25 A. Key electrical characteristics include a gate charge (Qg) of 44 nC at 10 V and an input capacitance (Ciss) of 850 pF at 30 V. The component supports a junction temperature up to 150°C and offers power dissipation ratings of 2 W at ambient temperature and 37 W at case temperature.
Verify the specific suffix '1EX' against official datasheets to confirm package type and marking details. Confirm end-of-life status and availability of qualified replacement components before finalizing design implementations. Ensure sourcing channels provide authentic parts with traceable documentation.
Select this component for designs requiring high voltage isolation and moderate current handling in through-hole configurations. Evaluate thermal management requirements carefully due to the relatively high on-resistance compared to lower voltage counterparts. Ensure gate drive circuitry can support the specified 10 V drive level for optimal performance.
