SILICON ZENER DIODES
50W, 6.8 THRU 200 VOLT
5% TOLERANCE
DESCRIPTION:
The CENTRAL SEMICONDUCTOR 1N2804B series
types are silicon Zener diodes manufactured in a
hermetically sealed metal case, designed for high
reliability industrial applications. Also available in
reverse polarity connection (replace “B” suffix with “RB”
suffix in part number - ex. 1N2804RB). The typical
lead diameter is 50 mils.
