DESCRIPTION
APPEARANCE
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
TO-3
