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 50mohm (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.
