SMA4122 1 Form A 100V / 30mΩ DC MOSFET Output Solid State Relay Description The SMA4122 is a DC, single-pole, single-throw, normally open solid-state relay in a 4 pin single inline package. The relay consists of an AlGaAs LED, optically coupled to a high performance Photo Diode Array (PDA), which in turn drives a low on-resistance, rugged source-to-source enhancement type DMOS transistor output. The SMA4122 has an extremely low on resistance of 15m (TYP) and a very high continuous load current rating of up to 6 amps. The combination of low on-resistance, small package outline and high load current capabilities make the SMA4122 a unique, unparalleled solid state relay. The SMA4122 comes standard in a 4 pin SIP package.
