1N6461 1N6468 Qualified Levels: Voidless Hermetically Sealed Unidirectional JAN, JANTX, and Available on Transient Voltage Suppressors JANTXV commercial versions Qualified per MIL-PRF-19500/551 DESCRIPTION This series of 500 watt voidless hermetically sealed unidirectional Transient Voltage Suppressors (TVS) are military qualified to MIL-PRF-19500/551 and are ideal for high-reliability applications where a failure cannot be tolerated. Working peak standoff voltages are available from 5.0 to 51.6 volts. They are very robust, using a hard glass casing and internal Category 1 metallurgical bonds. These devices are also available in a surface mount MELF package configuration.

V Breakdown Voltage: The voltage across the device at a specified current I in the breakdown region. (BR) (BR) Rated working standoff voltage: The maximum-rated value of dc or repetitive peak positive cathode-to-anode voltage V WM that may be continuously applied over the standard operating temperature. I Standby Current: The current through the device at rated stand-off voltage. D Peak Impulse Current: The maximum rated random recurring peak impulse current or nonrepetitive peak impulse I current that may be applied to a device. A random recurring or nonrepetitive transient current is usually due to an PP 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 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 .
