ultralow leakage: pad1 <1 pa ultralow capacitance: pad1 <0.8 pf two-leaded package negligible circuit leakage contribution circuit ?transparent? except to shunt high-frequency spikes simplicity of operation op amp input protection multiplexer overvoltage protection the pad/jpad/sstpad series of extremely low-leakage diodes provides a superior alternative to conventional diode technology when reverse current (leakage) must be minimized. they feature leakage currents ranging from ?1 pa (pad1) to ?100 pa (sstpad100) to support a wide range of applications. these devices are well suited for use in applications such as input protection for operational amplifiers. the hermetically sealed to-206af (to-72) package allows full military processing per mil-s-19500 (see military information). the t o-226a (to-92) plastic package provides a low-cost option. the to-236 (sot-23) package provides surface-mount capability. both j and sst series are available in tape-and-reel for automated assembly.
