Description
1N6461 MicroSemi Transient Voltage Suppressors 5V 500 W 5VWM 9VC Axial Uni-junction
This series of 500 watt voidless hermetically sealed unidirectional Transient Voltage Suppressor s (TVS) are military qualified to MIL – PRF – 19500/551 and are ideal for high – reliability applications where a failure cannot be tolerated. W orking peak “s tandoff” v oltage s are available from 5.0 to 51.6 v olts. They are very robust, using a hard glass casing and internal Category 1 metallurgical bonds. These devices are also available in a surface mount MELF package configuration.

Features, Applications
The 1N64xx series of transient voltage suppressors are designed to protect military and commercial electronic equipment from overvoltages caused by lightning, ESD, EFT, inductive load switching, and EMP. These devices are constructed using a p-n junction TVS diode in a hermetically sealed, voidless glass package. The hermetically sealed package provides high reliability in harsh environmental conditions. TVS diodes are further characterized by their high surge capability, low operating and clamping voltages, and a theoretically instantaneous response time. This makes them ideal for use as board level protection for sensitive semiconductor components. These devices are DESC QPL qualified to MIL-S-19500/551.
