OptoMOS Relay
INTEGRATED CIRCUITS DIVISION
Parameter Ratings Units Description
Blocking Voltage 250 V
The LCA120 is a single-pole, normally open
P
(1-Form-A) solid state relay that uses optically coupled
Load Current 170 mA & mA
rms DC
MOSFET technology to provide 3750V of input to
On-Resistance (max) 20
rms
output isolation.
Its optically coupled outputs, which use the patented
Features
OptoMOS architecture, are controlled by a highly
3750V Input/Output Isolation
rms efficient GaAIAs infrared LED.
Low Drive Power Requirements (TTL/CMOS
Compatible)
LCA120 can be used to replace mechanical relays,
High Reliability
and offers the superior reliability associated with
Arc-Free With No Snubbing Circuits
semiconductor devices. Because it has no moving
No EMI/RFI Generation
parts, it can offer faster, bounce-free switching in a
Small 6-Pin Package
more compact surface mount or thru-hole package.
Machine Insertable, Wave Solderable
Surface Mount Tape & Reel Version Available
