Overview

The LAA110 is a dual single-pole, normally open (1-Form-A) Solid State Relay (SSR) from IXYS Integrated Circuits Division. It utilizes optocoupled MOSFET technology to provide 3750Vrms of input-to-output isolation in a compact 8-pin package. This device is capable of switching both AC and DC loads up to 350V and 120mA.

Why Choose This Part

The LAA110 offers high reliability with no moving parts, eliminating contact bounce and mechanical wear common in electromechanical relays. Its low drive current requirements make it directly compatible with TTL and CMOS logic levels, while the dual-channel design saves board space in dense designs.

Applications

Telecommunications Switching
Ideal for hook switch, dial pulsing, and ground start applications due to its high isolation and FCC compatibility.
Instrumentation and Multiplexing
Used in data acquisition systems where low-noise switching and high-speed multiplexing are required without EMI/RFI generation.
Industrial Control Systems
Suitable for driving small solenoid valves or interfacing between low-voltage logic circuits and high-voltage AC/DC industrial peripherals.
Security and Alarm Systems
Provides reliable, bounce-free switching for sensor loops and alarm notification circuits.

Getting Started

To use the LAA110, design an input circuit with a current-limiting resistor to provide approximately 5mA to 10mA to the input LEDs. Ensure the load current does not exceed the 120mA rating and that the load voltage remains within the 0V to 350V range. For prototyping, the 8-pin DIP package is breadboard compatible, and the device is machine insertable for production wave soldering.
