DESCRIPTION
These high power 50W Zener diodes represented by the JEDEC registered
1N3305B thru 1N3350B and 1N4549B thru 1N4556B series provide voltage
regulation in a selection over a 3.9V to 200V 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 1N3305B thru 1N3350B and 1N4549B 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-PRF19500/358 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.
