1N821AUR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

The 1N821UR-1 – 1N829AUR-1 series of surface mount temperature compensated reference diodes provides both 6.2 V and 6.55 V nominal voltages and temperature coefficients as low as 0.0005 %/o C at a Zener test current of 7.5 mA. These glass surface mount DO-213AA (MELF) reference diodes are optionally available as RoHS compliant for commercial applications. This type of bonded Zener package construction is also available in JAN, JANTX, JANTXV and JANS military qualifications (RoHS compliant option not applicable). Microchip also offers other Zener Reference Diode products for a variety of voltages up to 200 V.

简介

1N821AUR属于分立半导体产品的二极管-齐纳-单。由制造生产的1N821AUR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。
