1N6469US THRU 1N6476US QPL 1500 Watt Surface Mount TVS POWER DISCRETES Features Description The 1N64xx series of transient voltage suppressors are 1500 Watts peak pulse power (tp = 10/1000s) designed to protect military and commercial electronic Voidless hermetically sealed glass package equipment from overvoltages caused by lightning, ESD, Metallurgically bonded EFT, inductive load switching, and EMP. These devices High surge capacity are constructed using a p-n junction TVS diode in a Unidirectional hermetically sealed, voidless glass package. The Available in JAN, JTX, and JTXV versions per hermetically sealed package provides high reliability in MIL-PRF-19500/552 harsh environmental conditions. TVS diodes are further characterized by their high surge capability, low operating Applications and clamping voltages, and a theoretically instantaneous Aerospace and industrial electronics response time. This makes them ideal for use as board Board level protection level protection for sensitive semiconductor components. Airborne systems These devices are DSCC QPL qualified to MIL-PRF- Shipboard systems 19500/552.
