M250
1 Form A
Solid State Relay
The M250 is a bi-directional, single-pole, single-throw, normally open multipurpose solid-state relay in a 4-pin miniature small outline
package. It is designed to replace electromechanical and reed relays in special applications that call for very fast switching rates. The relay
consists of an integrated circuit that drives two special source-to-source enhancement type DMOS transistors with extremely low output
capacitance and leakage current. The IC is optically coupled to a light emitting diode which controls its switching. The design of the circuit
makes it ideal for switching high frequency signals.
