M221

1 Form A

Solid State Relay

The M221 is a bi-directional, single-pole, single-throw, normally open multipurpose solid-state relay in a miniature 4-pin small outline

package. It is designed to replace electromechanical relays in general purpose switching applications. The relay consists of an integrated

circuit that drives two rugged source-to-source enhancement type DMOS transistors - optically coupled to a light emitting diode. The output

MOS transistors are protected with free-wheeling diodes that can handle up to 5A of inrush current, making the relay ideal for switching

lamps and highly inductive loads.
