SMA4124 Datasheet, PDF (1/6 Pages) Solid State Optronic – High Load Current (1A MAX Continuous)
SMA4124
1 Form A
600V / 1A
MOSFET Output Solid State Relay
Description
The SMA4124 is a single-pole, single-throw, normally open
multipurpose solid state relay. The circuit is composed of
an infra-red LED on the input side optically coupled to a
Photo Diode Array which drives back-to-back high voltage
enhancement type DMOS transistors on the output. The
SMA4124 has a high blocking voltage (600V) and is rated
for a continuous load current of 1A. The combination of
high blocking voltage, high load current, and small form
factor make the SMA4124 ideal for electromechanical and
reed relay replacement.
The SMA4124 comes standard in a 4 pin SIP package.
Applications
