Description
General part information
1N2818B-Zener-Diode Series
This series of high power 50W Zener diodes, JEDEC registered 1N2804B through 1N2846B and 1N4557B through 1N4564B, provide voltage regulation in values from 3.9V to 200V broad range of voltages. They may be operated up to 50W with adequate mounting heat sinking due to their low thermal resistance. These Zeners are also available in JAN, JANTX and JANTXV military qualifications.
