1N6642UB2R/TR

Overview

The Microchip Technology 1N6642UB2R/TR is a voidless hermetically sealed switching diode qualified per MIL-PRF-19500/578. It features ultra-fast recovery time and very low capacitance within a metallurgically bonded non-cavity glass package. The device supports an average rectified forward current of 300 mA at +75°C and withstands a peak reverse voltage of 75 V. Operating temperatures range from -65°C to +175°C, with a maximum junction-to-ambient thermal resistance of 250°C/W.

Feature Summary

Hermetically sealed in a voidless hard glass package with internal metallurgical bonding
Ultra-fast recovery time suitable for high-frequency applications
Very low junction capacitance for signal integrity
Qualified under MIL-PRF-19500/578 standards

Applications

High frequency data lines
RS-232 & RS-422 Interface Networks
Ethernet 10 Base T
Switching core drivers
Computers and peripheral equipment

Procurement Notes

Verify the specific qualification level (JAN, JANTX, JANTXV, or JANS) required for your application, as the base part number covers multiple military grades. Confirm tape and reel packaging specifications against EIA-296 standards if automated assembly is planned. Ensure lead material and plating requirements align with your soldering processes, noting that tin-lead plate is standard.

Selection Notes

Select this component when high reliability and radiation hardness are critical compared to commercial alternatives. The 1N6642 variant specifically offers a 75 V working peak reverse voltage, distinguishing it from the 1N6638 (150 V) and 1N6643 (50 V). Consider the hermetic seal for harsh environments where moisture ingress must be prevented, unlike standard plastic packages.

Part Context

This diode belongs to the JEDEC registered 1N66xx series of small-signal switching diodes manufactured by Microchip Technology (formerly Microsemi). These devices are designed to replace older industry standards like the 1N4148 and 1N914 while offering superior performance in terms of speed and leakage current. The 'U' suffix typically denotes surface mount or specific package variations within the broader family.
