1N6461 Thru QPL 1N6468 500 Watt Axial Leaded TVS TEL:805-498-2111 FAX:805-498-3804 DESCRIPTION FEATURES: The 1N64xx series of transient voltage suppressors are 500 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 are High surge capacity constructed using a p-n junction TVS diode in a Unidirectional hermetically sealed, voidless glass package. The Available in JTX, and JTXV versions per hermetically sealed package provides high reliability in MIL-S-19500/551 harsh environmental conditions. TVS diodes are further characterized by their high surge capability, low operating MECHANICAL CHARACTERISTICS: and clamping voltages, and a theoretically instantaneous Hermetically sealed glass package response time. This makes them ideal for use as board Tinned copper leads level protection for sensitive semiconductor components. Marking : P/N, date code, logo, & cathode band These devices are DESC QPL qualified to MIL-S-19500/551.
