AD2C112

1 Form B

400V / 35Ω

MOSFET Output Solid State Relay

Description

The AD2C112 is a bi-directional, single-pole, single-throw,

normally closed multipurpose relay. It is designed to

replace electro-mechanical relays in general purpose

switching applications. The relay consists of an integrated

circuit that drives two rugged drain-to-drain depletion type

DMOS transistors - optically coupled to a light emitting

diode. The device comes with up to 5kV input to output

isolation.

The AD2C112 comes standard in a miniature 4 pin DIP

package making it ideal for high-density board applications.
