Description

The SDM4102 is a DC, single-pole, single-throw, normally

closed 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

depletion type DMOS transistor. The SDM4102 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 SDM4102 a

unique, unparalleled solid state relay.

The SDM4102 comes standard in a 4 pin SIP package.
