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.

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.
