This document introduces a series of fast recovery glass rectifier products that are hermetically sealed with voidless-glass construction. They are ideal for high-reliability applications where a failure cannot be tolerated. These products have a rated current of 3.0 amps and working peak reverse voltages from 50 to 600 volts. They feature an internal 'Category I' metallurgical bond and are sealed with voidless-glass construction. In addition, other rectifier products with different current ratings and recovery time requirements are also available.
The Microsemi 1N5415US through 1N5420US series are voidless, hermetically sealed glass rectifiers designed for high‑reliability, fast‑recovery applications. They are available in surface‑mount (Package “E”/D‑5B) and axial‑lead versions, with a rated forward current of 3 A at 55 °C and 2 A at 100 °C.
These devices meet MIL‑PRF‑19500/411 requirements and feature low thermal resistance, high forward surge capability (80 A), and robust construction suitable for military and other demanding environments.
