Design a Custom BoardAbout This Component
Single-channel optocoupler with phototransistor output and integrated gallium arsenide LED, rated for 3750 VRMS AC isolation. Features low coupling capacitance (0.3 pF typical), adjustable current transfer ratio (CTR) from 50-600%, and wide temperature range operation. Commonly used in PLCs, modems, and isolated signal transmission applications requiring high safety compliance.
Package: SOIC-4-6 (4.4×3.6mm) · 4 pins
Why does this need a breakout?
This Toshiba optocoupler's 1.27mm pitch and compact 4.4×3.6mm footprint make hand-soldering impractical and breadboard use impossible. A breakout board converts the SMD package to through-hole pins or larger pads, enabling rapid prototyping and reliable connections in isolation and control circuits without reflow equipment.
