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
