1N3305 thru 1N3350B

and 1N4549B thru 1N4556B

50 WATT ZENER DIODES

S C O T T S D A L E D I V I S I O N

DESCRIPTION

APPEARANCE

These high power 50 W Zener diodes represented by the JEDEC

registered 1N3305 thru 1N3350B and 1N4549 thru 1N4556B 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.

DO- 5

(DO-203AB)

FEATURES

APPLICATIONS / BENEFITS

•

JEDEC registered 1N3305 thru 1N3350B 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

1N4549 thru 1N4556B

•

Internal solder bond construction

Hermetically sealed (welded)

Zener Voltage 3.9V to 200V.

Also available in JAN, JANTX, and JANTXV

qualifications per MIL-PRF-19500/358 by adding

the JAN, JANTX, or JANTXV prefixes to part

numbers for desired level of screening; (e.g.

JANTX1N3305B, JANTXV1N3318B, etc.

•

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

suffix respectively

•

Reverse polarity available

Nonsensitive to ESD per MIL-STD-750 Method

1020

•

Standard polarity is anode to case

•

Inherently radiation hard as described in

Microsemi MicroNote 050

Reverse polarity with cathode to case by

designating R suffix in part number, e.g.

1N3305RB, etc.

•

Consult factory for surface mount equivalents

MAXIMUM RATINGS
