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.)
