1N4151/TR

Single Diodes Overview

The Microchip Technology 1N4151/TR is a JEDEC registered silicon signal diode housed in a hermetically sealed DO-35 glass package. It features an average rectified forward current of 200 mA and a maximum non-repetitive sinusoidal surge current of 500 mA. The device supports a working peak reverse voltage of 75 V and operates within a junction temperature range of -65°C to +150°C. Electrical characteristics include a maximum reverse current of 50 nA at the rated voltage, a junction capacitance of 4 pF at 0 V, and a reverse recovery time of 2 ns.

Single Diodes Feature Summary

• Hermetically sealed glass construction with internal metallurgical bonding for high reliability.
• Very fast switching speeds combined with minimal reverse recovery times.
• Low capacitance design suitable for high-frequency data lines.

Single Diodes Applications

• High frequency data lines
• RS-232 & RS-422 interface networks
• Ethernet 10 Base T
• Switching core drivers

Single Diodes Procurement Notes

Verify that the specific ordering suffix matches the required RoHS compliance status, as the datasheet indicates both compliant and non-compliant versions exist. Confirm the screening level against MIL-PRF-19500 if military-grade reliability is necessary. Ensure the package type corresponds to the standard axial lead configuration provided in the mechanical specifications.

Single Diodes Selection Notes

Select this component when a small-signal switching diode requires hermetic sealing and metallurgical bonding. The 75 V reverse voltage rating distinguishes it from lower-voltage variants like the 1N4149. Consider the 2 ns reverse recovery time for applications demanding rapid signal transitions. Verify thermal limits against the specified junction temperature range during operation.

Single Diodes Part Context

This part belongs to the 1N4149/1N4151/1N4154 series of computer switching diodes manufactured by Microchip Technology (formerly Microsemi). These devices are designed for fast switching applications and feature double-plug DO-35 packages. The series includes various voltage ratings and is available with different screening levels for commercial or high-reliability environments.

Single Diodes Replacement Considerations

The 1N4149-1 serves as a functional substitute but exhibits a slower reverse recovery time of 4 ns compared to the 2 ns of the 1N4151-1. The 1N4154-1 offers similar speed but has a lower working peak reverse voltage of 35 V. Ensure any replacement maintains the required hermetic seal and package dimensions.
