1N6461US – 1N6468US Voidless Hermetically Sealed Unidirectional Transient Voltage Suppressors Qualified per MIL-PRF-19500/551 Qualified Levels: JAN, JANTX, and JANTXV Available on commercial versions DESCRIPTION This surface mount 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 axial-leaded packages for thru-hole mounting. Important: For the latest information, visit our website http://www.microsemi.com. “B” SQ-MELF Package FEATURES • • • • • • • • Surface mount equivalent of JEDEC registered 1N6461 thru 1N6468 series. Available as 500 watt peak pulse power (P PP ). Working peak “standoff” voltage (V WM ) from 5.0 to 51.6 volt. High surge current and peak pulse power provides transient voltage protection for sensitive circuits. Triple-layer passivation. Internal “Category 1” metallurgical bonds. Voidless hermetically sealed glass package. JAN, JANTX, and JANTXV qualifications available per MIL-PRF-19500/551. Other screening in reference to MIL-PRF-19500 is also available. (See part nomenclature for all available options.) • RoHS compliant versions available (commercial grade only). Also available in: “B” Package (axial –leaded) 1N6461 - 1N6468 APPLICATIONS / BENEFITS • • • • • • • Military and other high-reliability applications. Extremely robust construction. ESD and EFT protection per IEC61000-4-2 and IEC61000-4-4 respectively. Protection from secondary effects of lightning per select levels in IEC61000-4-5. Square-end-cap terminals for easy placement. Nonsensitive to ESD per MIL-STD-750 method 1020. Inherently radiation hard as described in Microsemi “MicroNote 050”.

Breakdown Voltage: The voltage across the device at a specified current I (BR) in the breakdown region. Rated 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. 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 (I PP ) 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 I PP and V C .
