1N6461US THRU 1N6468US QPL 500 Watt Surface Mount TVS POWER DISCRETES Description The 1N64xx series of transient voltage suppressors are designed to protect military and commercial electronic equipment from overvoltages caused by lightning, ESD, EFT, inductive load switching, and EMP. These devices are constructed using a p-n junction TVS diode in a hermetically sealed, voidless glass package. The hermetically sealed package provides high reliability in harsh environmental conditions. TVS diodes are further characterized by their high surge capability, low operating and clamping voltages, and a theoretically instantaneous response time. This makes them ideal for use as board level protection for sensitive semiconductor components. These devices are DESC QPL qualified to MIL-S-19500/ 551. Features 500 Watts peak pulse power (tp = 10/1000µs) Voidless hermetically sealed glass package Metallurgically bonded High surge capacity Unidirectional Available in JTX, and JTXV versions per MIL-S-19500/551 Applications Aerospace and industrial electronics Board level protection Airborne systems Shipboard systems Ground systems Mechanical Characteristics Hermetically sealed glass package Absolute Maximum Ratings Rating Peak Pulse Power (tp = 10 x 1000µs) Storage Temperature Range Steady-State Power Dissipation @ TL = 75°C (3/8") Symbol P pk TSTG PD Value 500 -65 to +175 3 Units Watts °C Watts Revision: August 8, 2007 1 www.semtech.com 1N6461US THRU 1N6468US POWER DISCRETES Electrical Characteristics Electrical specifications @ TA = 25°C unless otherwise specified.
