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.
FEATURES
• Surface mount equivalent of JEDEC registered 1N6461 thru 1N6468 series.
• Available as 500 watt peak pulse power (PPP).
• Working peak “standoff” voltage (VWM) 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).
