Single Diodes Procurement Notes

This component is discontinued and classified as End of Life by the manufacturer. Availability is restricted to existing inventory or final time buys. Procurement should verify stock status directly with authorized distributors or the manufacturer's sales team. Last purchase orders may be subject to specific cutoff dates defined in the official End of Life notice.

Single Diodes Selection Notes

Designers requiring this specific part number must account for its discontinued status. The manufacturer explicitly recommends substituting the 1N4148 TR as the designated replacement for the 1N4446 TR. Selection should prioritize verifying pinout compatibility and ensuring the alternative meets all required electrical parameters for the target application before integration.

Single Diodes Part Context

The 1N4446 TR is part of the broader 1N4448 series of silicon switching diodes produced by Central Semiconductor Corp. This series was designed for high-speed switching applications. The manufacturer has formally transitioned these devices to End of Life status due to declining demand, following standard product management processes regarding sustainability levels.

Single Diodes Replacement Considerations

Official documentation identifies the 1N4148 TR as the direct replacement for the 1N4446 TR. Engineers should validate that the substitute meets all necessary voltage, current, and speed requirements for the specific circuit design.
