1N8172 Low-Capacitance Transient Voltage Suppressors

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.

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. APPLICATIONS / BENEFITS
 High reliability transient protection.
 Extremely robust construction.
 Working peak “standoff” voltage (VWM) from 6.8 to 170 volts.
 Available as 150 W peak pulse powe.
