Single FETs, MOSFETs Procurement Notes

This component is officially classified as obsolete and no longer manufactured by the original producer. Sourcing requires reliance on third-party distributors holding existing stock or surplus inventory. Verification of part authenticity and physical condition is critical due to the age of available units. Buyers should confirm that replacement alternatives meet all necessary electrical and mechanical specifications before integration into new designs.

Single FETs, MOSFETs Selection Notes

Designers seeking this specific part number must evaluate its discontinued status carefully. Current availability is limited to distributor stock rather than direct manufacturer production. Alternative components from other manufacturers may offer similar performance metrics but require thorough validation against the original circuit requirements. Engineers should prioritize verifying pin compatibility and thermal characteristics when selecting substitutes.

Single FETs, MOSFETs Part Context

The BFL4037 belongs to the BFL40 series of power MOSFETs produced by onsemi. This series was engineered for general-purpose high-voltage switching tasks. The specific model provides a balance of voltage handling and current carrying capability suitable for medium-power industrial applications. Its discontinuation reflects standard product lifecycle management practices within the semiconductor industry.
