1N4688中文资料Zener Diode Single 2-Pin 4.7V, 5%, 500mW DO-35 Bag数据手册Microchip规格书

描述 Description

The 1N4678-1 thru 1N4717-1 series of 0.5 watt Zener voltage regulators provides a selection from 1.8 to 43 volts in standard 5% tolerances as well as tighter tolerances. These axial leaded glass DO-35 Zeners are available with an internal metallurgical bond similar to military requirements for similar Zeners. Microchip also offers numerous other Zener products to meet higher and lower power applications.

简介

1N4688属于分立半导体产品的二极管-齐纳-单。由制造生产的1N4688二极管 - 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。
