1N4976CUS数据手册分立半导体产品的二极管-齐纳-单规格书PDF

描述 Description

This surface mount Zener Voltage Regulator series is military qualified to MIL-PRF-19500/356 and is ideal for high-reliability applications where a failure cannot be tolerated. These industry-recognized 5 Watt Zener Voltage Regulators are hermetically sealed with voidless-glass construction using an internal metallurgical bond. It includes Zener selections from 3.3 to 390 volts in standard 5% tolerances as well as tighter tolerances identified by different suffix letters on the part number. They are also available in axial-leaded packages for thru hole mounting by deleting the “US” suffix (see separate data sheet for 1N4954 thru 1N4996, 1N5968 thru 1N5969, and 1N6632 thru 1N6637). Microchip also offers numerous other Zener products to meet higher and lower power ratings in both thru-hole and surface mount packages.

简介

1N4976CUS属于分立半导体产品的二极管-齐纳-单。由制造生产的1N4976CUS二极管 - 齐纳 - 单齐纳二极管可用于以反向击穿模式工作，并根据以这种方式使用时的行为来分类。这些器件可用作电压基准或限压用途，还可以用作类似于整流二极管的单向电流阀，但它们在这种模式下的性能通常不如专用器件理想。该系列产品的每个器件封装恰好实现该功能的一个实例。
