SMA4115

1 Form A

60V / 75mΩ

DC MOSFET Output Solid State Relay

Description

The SMA4115 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 one low on-resistance, rugged source-to-source

enhancement type DMOS transistor. The SMA4115 has

an extremely low on resistance of 50m

 (TYP) and a very

high continuous load current rating of up to 3.4A. The

combination of low on-resistance, small package outline

and high load current capabilities make the SMA4115 a

unique, unparalleled solid state relay.

The SMA4115 comes standard in a 4 pin SIP package.
