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.
