1N8172US General 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.

Key Features

High surge current and peak pulse power unidirectional protection for sensitive circuits.
Very low capacitance for high frequency or high baud rate applications.
Bidirectional capability with two devices in anti-parallel (see Figure 5).
Triple-layer passivation.
Internal “Category 1” metallurgical bonds.
Voidless hermetically sealed glass package.
RoHS compliant versions are available.
