1N8170

1N8149 – 1N8182 Available 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 hardglass 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. Important: For the latest information, visit our website http://www.microsemi.com. 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.

Breakdown Voltage: The voltage across the device at a specified current I(BR) in the breakdown region. Working Standoff Voltage: The maximum-rated value of dc or repetitive peak positive cathode-to-anode voltage that may be continuously applied over the standard operating temperature. Standby Current: The current through the device at rated stand-off voltage. Breakdown Current: The current used for measuring Breakdown Voltage V(BR) Peak Impulse Current: The maximum rated random recurring peak impulse current or nonrepetitive peak impulse current that may be applied to a device. A random recurring or nonrepetitive transient current is usually due to an external cause, and it is assumed that its effect will have completely disappeared before the next transient arrives. Clamping Voltage: The voltage across the device in a region of low differential resistance during the application of an impulse current (IPP) for a specified waveform. Peak Pulse Power. The rated random recurring peak impulse power or rated nonrepetitive peak impulse power. The impulse power is the maximum-rated value of the product of IPP and VC. Total Capacitance: The total small signal capacitance between the diode terminals of a complete device. Inverse Blocking Voltage: The maximum-rated value of dc or peak blocking voltage in the inverse direction. Blocking Leakage Current: The current through the device at the rated inverse blocking voltage (VWIB).
