DESCRIPTION

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 TO-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. (See Packaging

Information.)
