Description
General part information
1N4551 Series
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. Microchip also offers numerous other Zener products to meet higher and lower power applications
