WWW.Microsemi .COM SCOTTSDALE DIVISION 1N3305 thru 1N3350B and 1N4549B thru 1 N4556B 50 WATT ZENER DIODES DESCRIPTIO N These high power 50 W Zener diodes re presented by the JEDEC registered 1N330 5 thru 1N3350B and 1N4549 thru 1N4556B series provide voltage regulation in a selection over a 3.9 V to 200 V broad r ange of voltages. They may be operated up to 50 W with adequate mounting and h eat sinking with their low thermal resi stance. These Zeners are also available in JAN, JANTX, JANTXV military qualifi cations. Microsemi also offers numerous other Zener products to meet higher an d lower power applications. APPEARANCE IMPORTANT: For the most
