1N4454TR

Overview

The onsemi 1N4454TR is a silicon epitaxial planar diode designed for high-speed switching applications. It features a maximum repetitive peak reverse voltage of 75 V and an average forward rectified current of 200 mA at 25°C. The device exhibits a fast reverse recovery time of 4 ns, ensuring minimal switching losses in digital circuits. Electrical characteristics include a maximum forward voltage of 1 V at 10 mA and a low reverse leakage current of 100 nA at 75 V. It supports a non-repetitive peak forward surge current of 4 A and operates within a junction temperature range of -65°C to +175°C.

Feature Summary

• High-speed switching capability with 4 ns reverse recovery time
• Hermetically sealed construction for environmental stability
• Double plug metallurgical bond design for mechanical robustness
• Wide operating temperature range suitable for demanding environments

Applications

• Digital logic circuit protection
• Computer interface signal conditioning
• High-frequency switching power supplies
• Pulse generation and shaping networks

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging when sourcing from distributors. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the procurement channel provides valid traceability for the onsemi manufacturing lot. Cross-reference datasheet revisions to confirm electrical parameter consistency across production batches.

Selection Notes

Select this component when a 75 V reverse voltage rating is required rather than higher voltage alternatives like the 1N4448. The DO-35 axial package is appropriate for through-hole mounting where surface area constraints are not critical. Consider the 200 mA current limit for load requirements; higher current needs may require different rectifier types. Verify thermal management capabilities align with the specified junction temperature limits.

Part Context

This part belongs to the standard 1N4454 series of small-signal switching diodes manufactured by onsemi. It serves as a general-purpose semiconductor device widely used in consumer electronics and industrial control systems. The TR suffix denotes a specific bulk packaging format intended for automated assembly processes, distinguishing it from loose or cut-tape variants.
