SMA4120 - Solid State Relay
The SMA4120 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 SMA4120 has a h
