1N5415US/TR

Overview

The Microchip Technology 1N5415US/TR is a surface mount fast recovery glass rectifier designed for high-reliability applications. It features a voidless hermetically sealed glass package with tungsten slugs and internal Category 1 metallurgical bonds. The device supports working peak reverse voltages from 50 to 600 volts, with the 1N5415 variant rated at 50V. Key electrical parameters include an average rectified forward current of 3A at +55°C ambient temperature, a maximum reverse recovery time of 150ns, and a forward surge current capability of 80A. The junction temperature range spans from -65°C to +175°C.

Feature Summary

• Voidless hermetically sealed glass construction with tungsten slugs
• Internal Category 1 metallurgical bonds for robustness
• Quadruple-layer passivation
• Inherently radiation hard

Applications

• Military and other high-reliability applications
• General rectifier applications including bridges and half-bridges
• Catch diodes in high-speed circuits

Procurement Notes

Verify that the specific ordering suffix matches the required qualification level (JAN, JANTX, JANTXV, or JANS) as these levels dictate the manufacturing lot traceability and testing standards per MIL-PRF-19500/411. Confirm RoHS compliance status if applicable, noting that compliant versions are available on commercial grade only. Ensure the tape and reel packaging aligns with EIA-481-B standards for automated assembly processes.

Selection Notes

Select this component when a surface mount equivalent to the axial-leaded 1N5415 series is required without compromising reliability. The device is suitable for environments where failure cannot be tolerated due to its controlled avalanche characteristics and low thermal resistance. Consider the 150ns reverse recovery time for switching frequency requirements and ensure the 50V peak reverse voltage rating accommodates circuit transients.

Part Context

This part belongs to the 1N5415US through 1N5420US series of fast recovery rectifiers. These devices serve as the surface mount equivalents to the industry-recognized JEDEC registered 1N5415 through 1N5420 axial-leaded series. The series covers working peak reverse voltages ranging from 50 to 600 volts, providing options for various voltage ratings within the same physical package footprint.

Replacement Considerations

Direct replacements include other manufacturers' surface mount fast recovery rectifiers meeting the 3A current and 50V reverse voltage specifications. Verify pinout compatibility and thermal resistance values. For military specifications, substitute parts must meet MIL-PRF-19500/411 requirements for the desired qualification level.
