1N4555B - 50WATT ZENER DIODES

Download the 1N4555B datasheet PDF. This datasheet also covers the 1N4549B variant, as both devices belong to the same 50watt zener diodes family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key Features

  • 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.

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. APPEARANCE IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.
