1N4446 TR

Overview

The 1N4446 TR is a silicon switching diode manufactured by Central Semiconductor Corp. It belongs to the 1N4448 series, which has been officially classified as End of Life (EOL). The component utilizes a DO-35 through-hole package and features a single junction configuration. Key electrical specifications include a peak reverse voltage of 100 V, a maximum forward current of 200 mA, and a surge current rating of 4 A. The device exhibits a fast recovery time of 4 ns with a forward voltage drop of 1 V at rated current. Operating temperatures range from -65°C to +175°C.

Feature Summary

High-speed switching capability with rapid recovery characteristics
Robust construction suitable for general-purpose applications
Through-hole mounting compatibility via standard axial leaded package

Applications

General-purpose signal rectification
High-speed switching circuits
Clamping and protection stages in electronic designs

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.

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.

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.

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.
