This series of industry recognized voidless hermetically sealed unid i r ectional Transi ent
V oltage S uppressor (TVS) desi gns is military qu al ified and ar e ideal for high-reliability
applications wher e a fail ure cannot be t olerated. Th ey provide a Wor king P eak “S tandoff”
V oltage sel ection from 30.5 to 175 volts with 1500 watt ratings. They are very robust in hard-
glass construct i on and als o us e an internal metallu r gical bond id entified as “Category 1” for
high reliability app lic at ion s . These d evices are also av ai lable i n a s urfac e mount MELF
pack age configuration as a speci al or der. Microsemi also offers n umerous oth er TV S
products to meet higher and lower peak pulse power and voltage ratings in both through-hole
and surface-mou nt pac kag es.
