FEATURES
DESCRIPTION
High OFF Isolation. . . . . . . . . . . . . . . . . 1 pA max DPAD1
Excellent Isolation between diodes. . . . . . Typical 20 fA
Matched Capacitance
Calogic’s ultra low leakage dual pico amp diodes out perform
conventional diodes for applications where reverse current
(leakage) is critical and must be kept at a minimum. The
devices have very low capacitance and are also fast
switching. Housed in a compact dual hermetic package and a
plastic surface mount SO-8 this product is also available in
chip form for hybrid uses.
