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.)
