描述 Description

The popular 1N821 thru 1N829A series of Zero-TC Reference Diodes provides a selection of both 6.2 V and 6.55 V nominal voltages and temperature coefficients to as low as 0.0005%/o C for minimal voltage change with temperature when operated at 7.5 mA. These glass axialleaded DO-35 reference diodes are optionally available with an internalmetallurgical-bond by adding a “-1” suffix. This type of bonded Zener package construction is also available in JAN, JANTX, and JANTXV military qualifications. Microchip also offers numerous other Zener Reference Diode products for a variety of other voltages up to 200 V.

簡介

1N821A-1E3屬于分立半導(dǎo)體產(chǎn)品的二極管-齊納-單。由制造生產(chǎn)的1N821A-1E3二極管 - 齊納 - 單齊納二極管可用于以反向擊穿模式工作，并根據(jù)以這種方式使用時的行為來分類。這些器件可用作電壓基準(zhǔn)或限壓用途，還可以用作類似于整流二極管的單向電流閥，但它們在這種模式下的性能通常不如專用器件理想。該系列產(chǎn)品的每個器件封裝恰好實(shí)現(xiàn)該功能的一個實(shí)例。
