DESCRIPTION
These high power 50W Zener diodes represented by the JEDEC registered 1N2804B thru 1N2846B and 1N4557B thru 1N4564B series provide voltage regulation in a selection over a 3.9V to 200V broad range of voltages. They may be operated up to 50W 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 1N2804 thru 1N2846B and 1N4557 thru 1N4564B
➤ Internal solder bond construction
➤ Hermetically sealed (welded)
➤ Zener Voltage 3.9V to 200V
➤ Also available in JAN, JANTX, and JANTXV qualifications per MIL-PRF-19500/114 by adding the JAN, JANTX, or JANTXV prefixes to part numbers for desired level of screening; (e.g. JANTX1N2804B, etc.
➤ Standard polarity is anode to case
