1N6138A 1N6173A Qualified Levels: Voidless Hermetically Sealed Bidirectional JAN, JANTX, JANTXV Available on Transient Voltage Suppressors and JANS commercial Qualified to MIL-PRF-19500/516 versions DESCRIPTION This series of industry recognized voidless, hermetically sealed bidirectional Transient Voltage Suppressors (TVS) are military qualified to MIL-PRF-19500/516 and are ideal for high-reliability applications where a failure cannot be tolerated. They provide a working peak standoff voltage selection from 5.2 to 152 Volts with a 1500 W rating for a 10/1000 s pulse. They are very robust in hard-glass construction and use internal Category 1 metallurgical bonds for high reliability. These devices are available as both a non-suffix part and an A version part involving different voltage tolerances as described in the nomenclature section. These devices are also available in a surface mount MELF package configuration.

V and 5% lower I (BR) PP table SYMBOLS & DEFINITIONS Symbol Definition Temperature Coefficient of Breakdown Voltage: The change in breakdown voltage divided by the change in V(BR) temperature that caused it expressed in %/C or mV/C. V Breakdown Voltage: The voltage across the device at a specified current I in the breakdown region. (BR) (BR) Working Standoff Voltage: The maximum-rated value of dc or repetitive peak positive cathode-to-anode voltage that V WM may be continuously applied over the standard operating temperature. I Standby Current: The current through the device at rated stand-off voltage. D Clamping Voltage: The voltage across the device in a region of low differential resistance during the application of an V C impulse current (I ) for a specified waveform. PP Peak Pulse Power. The rated random recurring peak impulse power or rated nonrepetitive peak impulse power. The P PP impulse power is the maximum-rated value of the product of I and V .
