• Industrial motor control systems

Single FETs, MOSFETs Procurement Notes

Verify the manufacturer designation, as Sanyo Semiconductor assets were acquired by ON Semiconductor. Confirm the specific suffix or marking on the component body to ensure it matches the original Sanyo BFL4004 specifications rather than a modern equivalent. Cross-reference datasheets from authorized distributors to validate electrical parameters against the legacy documentation.

Single FETs, MOSFETs Selection Notes

Select this component when designing circuits requiring high blocking voltage with moderate current handling in a through-hole form factor. Ensure thermal management strategies account for the specified power dissipation limits at both ambient and case temperatures. Verify that the gate drive requirements align with the MOSFET's threshold characteristics for efficient switching performance.

Single FETs, MOSFETs Part Context

This component belongs to the family of discrete power semiconductors produced by Sanyo Semiconductor before its acquisition. It serves as a legacy part number for engineers maintaining older industrial equipment designs. The TO-220FI(LS) package indicates a specific lead style and insulation profile distinct from standard TO-220 variants.
