SMA4122 Datasheet, PDF (1/6 Pages) Solid State Optronic – DC MOSFET Output Solid State Relay

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.
Applications
 Reed Relay / EMR Replacement
 Meter reading systems
