Dual 1 Form A Solid State Relay (Low Capacitance)
LH1544AAC, LH1544AACTR, LH1544AB
Vishay Semiconductors
DESCRIPTION
These dual SSRs (LH1544, dual 1 form A) are SPST normally
open switches which can replace electromechanical relays
in many applications. The relays provide a low-capacitance,
high-voltage switch contact with high off-resistance and low
switch-offset voltage. These characteristics, combined with
high-speed actuation, result in an SSR which is ideal for
small signal and DC instrumentation applications.
The relays are constructed by using a GaAlAs LED for
actuation control and an integrated monolithic die for the
switch output. The die is comprised of a photodiode array,
switch-control circuity, and low-capacitance MOSFET
switches.
