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
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.
Standard polarity is anode to case
Reverse polarity with cathode to case by
designating R suffix in part number, e.g.
1N3305RB, etc.
Consult factory for surface mount equivalents
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
Reverse polarity available
Nonsensitive to ESD per MIL-STD-750 Method
1020
Inherently radiation hard as described in
Microsemi MicroNote 050
