Overview
SMA4123 1 Form A 60V / 200mΩ MOSFET Output Solid State Relay Description The SMA4123 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 low on resistance enhancement type DMOS transistors on the output.
The SMA4123 has a low on resistance of 160mΩ (TYP) and a high continuous load current rating of up to 2.
2 amps.
The SMA4123 comes standard in a 4 pin SIP package.
Applications • Reed Relay Replacement • Mechanical Relay Replacement • Medical Equipment • Battery Monitoring • Multiplexers • Test Equipment Schematic Diagram - LED 1 + LED 2 ...
