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.

TO-3

(TO-204AD)

FEATURES

APPLICATIONS / BENEFITS

•

JEDEC registered 1N2804 thru 1N2846B and

•

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

1N4557 thru 1N4564B

•

Internal solder bond construction

Hermetically sealed (welded)

Zener Voltage 3.9V to 200V.

•

Consult factory for +/-2% or +/-1% with a C or D

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.

suffix respectively

•

Reverse polarity available

Nonsensitive to ESD per MIL-STD-750 Method

JANTX1N2804B, etc.

Standard polarity is anode to case

1020

•

Inherently radiation hard as described in

Microsemi MicroNote 050

Reverse polarity with cathode to case by designating

R suffix in part number, e.g. 1N2804RB, etc.

•

Consult factory for surface mount equivalents
