SMA4124 - Solid State Relay

General 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.

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.
