1N6642UB2/TR

Overview

The Microchip Technology 1N6642UB2/TR is a voidless hermetically sealed switching diode qualified per MIL-PRF-19500/578. It features an ultra-fast recovery time of 5.0 ns and very low junction capacitance of 2.8 pF at 1 MHz. The device operates with a working peak reverse voltage of 75 V and supports an average rectified forward current of 300 mA. It utilizes a metallurgically bonded non-cavity glass package for high reliability.

Feature Summary

Hermetically sealed in a voidless hard glass package with internal metallurgical bonding
Ultra-fast switching performance characterized by a 5.0 ns reverse recovery time
Low parasitic capacitance suitable for high-frequency signal processing

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 that the tape and reel packaging aligns with your automated assembly equipment specifications. Ensure compliance with environmental directives if RoHS status is mandatory, noting that commercial versions may differ from military qualifications.

Selection Notes

Select this component when high-density mounting and fast switching speeds are critical. The D-package offers small size advantages for through-hole applications. Consider the 75 V reverse voltage rating to ensure adequate margin for your circuit's peak operating conditions. Evaluate thermal derating requirements based on ambient temperature and lead length constraints defined in the datasheet.

Part Context

This diode belongs to the 1N6638, 1N6642, and 1N6643 family of JEDEC registered switching diodes. These devices are designed as replacements for standard signal diodes like the 1N4148 and 1N914 but offer superior radiation hardness and hermetic sealing capabilities suitable for harsh environments.
