MOC256-M

DESCRIPTION

The MOC256-M is an AC input phototransistor optocoupler. The device consists of two infra-

red emitters connected in anti-parallel and coupled to a silicon NPN phototransistor detector.

It is designed for applications requiring the detection or monitoring of AC signals. The device

is constructed with a standard SOIC-8 footprint.

FEATURES

• UL Recognized File (#E90700, Volume 2)

• VDE recognized (File #136616)

- Ordering option V (i.e. MOC256V-M)

• Industry Standard SOIC-8 Surface Mountable Package, with 0.050" lead spacing

•Available in Tape and Reel Option

• Bidirectional AC Input (Protection Against Reversed DC Bias)

• Guaranteed CTR Symmetry of 2:1 Maximum

• High Input-Output Isolation of 2500 Vac (rms) Guaranteed
