M272
1 Form B
Solid State Relay
DESCRIPTION
The M272 is a bi-directional, single-pole, single-throw, normally closed multipurpose solid-state relay in a miniature 4-pin small outline
package. It is designed to be a cost-effective replacement of reed relays in low voltage applications. The relay consists of an integrated
circuit that drives two rugged source-to-source depletion 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 1.5A of inrush current, making the relay ideal for switching
lamps and highly inductive loads.
