50 Watt Zener Diodes
These high power 50 W Zener diodes represented by the JEDEC registered
SCOTTSDALE DIVISION
DESCRIPTION
1N2804 thru 1N2846B and 1N4557 thru 1N4564B 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.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
• JEDEC registered 1N2804 thru 1N2846B and
1N4557 thru 1N4564B
