DESCRIPTION

These high power 50 W Zener diodes represented by the JEDEC registered 1N2804 thru 1N2846B and 1N4557 thru 1N4564B series provide voltage regulation in a selection over a 3.9 V to 200 V broad range of voltages. They may be operated up to 50 W with adequate mounting and heat sinking with their low thermal resistance. These Zeners are also available in JAN, JANTX, JANTXV military qualifications. Microsemi also offers numerous other Zener products to meet higher and lower power applications.

FEATURES

? JEDEC registered 1N2804 thru 1N2846B and 1N4557 thru 1N4564B

? Internal solder bond construction

? Hermetically sealed (welded)

? Zener Voltage 3.9V to 200V.

? Also available in JAN, JANTX, and JANTXV qualifications per MIL-PRF-19500/114 by adding the JAN, JANTX, or JANTXV prefixes to part numbers for desired level of screening; (e.g. JANTX1N2804B, etc.

? Standard polarity is anode to case

? Reverse polarity with cathode to case by designating R suffix in part number, e.g. 1N2804RB, etc.

? Consult factory for surface mount equivalents

APPLICATIONS / BENEFITS

? Regulates voltage over a broad operating current and temperature range

? Standard voltage tolerances are +/- 5 with B suffix, +/-10 with an A suffix, and +/-20 with no suffix

? Consult factory for +/-2 or +/-1 with a C or D suffix respectively

? Inherently radiation hard as described in Microsemi MicroNote 050

JAN1N2821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JAN1N2821二極管 - 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。
