DESCRIPTION

This 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 surface-mount packages (see separate data sheet for 1N4954US thru 1N4996US, 1N5968US thru 1N5969US, and 1N6632US thru 1N6637US). Microsemi also offers numerous other Zener products to meet higher and lower power ratings in both thru-hole and surface mount packages.

JANTX1N4978D屬于分立半導(dǎo)體產(chǎn)品 > 二極管 - 齊納 - 單。美高森美公司制造生產(chǎn)的JANTX1N4978D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現(xiàn)該功能的一個實例。
