| 1N6469 thru 1N6476 Voidless-Hermetically-Sealed Unidirectional Transient Suppressors SCOTTSDALE DIVISION DESCRIPTION This series of industry recognized voidless-hermetically-sealed Unidirectional Transient Voltage Suppressor (TVS) designs is military qualified to MIL-PRF19500/552 and are ideal for high-reliability applications where a failure cannot be tolerated. They provide a Working Peak "Standoff" Voltage selection from 5.0 to 51.6 Volts with 1500 W ratings. They are very robust in hard-glass construction and also use an internal metallurgical bond identified as Category I for high reliability applications. The 1500 W series is military qualified to MIL-PRF-19500/552. These devices are also available in a surface mount MELF package configuration by adding a "US" suffix (see separate data sheet for 1N6469US thru 1N6476AUS). Microsemi also offers numerous other TVS products to meet higher and lower peak pulse power and voltage ratings in both through-hole and surface-mount packages. IMPORTANT: For the most current data, consult MICROSEMI's website: http://www.microsemi.com APPEARANCE WWW .

Working Peak Voltage: The maximum peak voltage that can be applied over the operating temperature range. This is also referred to as Standoff Voltage. Maximum Standoff Current: The maximum current that will flow at the specified voltage and temperature. Maximum clamping voltage at specified IPP (Peak Pulse Current) at the specified pulse conditions. Peak Pulse Power: The peak power dissipation resulting from the peak impulse current IPP. GRAPHS Pulse current (IP) in percent of IPP Peak Value IPP 1N6461 - 1N6468 1N6469 - 1N6476 Pulse time duration (tp) is defined as that point where IP decays to 50% of peak value (IPP).
