SMA4123

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.
