Voidless-Hermetically-Sealed Unidirectional 150 W
Low-Capacitance Transient Voltage Suppressors
DESCRIPTION
This series of voidless-hermetically-sealed unidirectional low-capacitance Transient Voltage Suppressor
(TVS) designs are ideal for protecting higher frequency applications in high-reliability applications where
a failure cannot be tolerated. They include a unique rectifier diode in series and opposite direction from
the TVS to achieve a very low capacitance of 4 pF. This product series provides a working peak
“standoff” voltage selection from 6.8 to 170 volts with 150 watt ratings. They are very robust in hard-
glass construction and also use an internal metallurgical bond identified as Category 1 for high reliability
applications. These devices are also available in axial leaded packages for thru-hole mounting.
