1N8182 [Microchip]

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 5.0V to 170V with 150-watt ratings. They are very robust in hard-glass construction and use an internal metallurgical bond identified as Category 1 for high reliability applications. These devices are also available in axial leaded packages for surface mounting.
