M201

1 Form A

600V / 20Ω

MOSFET Output Solid State Relay

Description

The M201 is a bi-directional, single-pole, single-throw,

normally open multipurpose solid-state relay in a miniature

4-pin small outline package. With a high blocking voltage

(600V) and low on-resistance, it is ideally suited to high

voltage applications requiring higher load currents. 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 1.5A of inrush current

The M201 comes standard in a 4 pin SOP package.
