Design a Custom BoardAbout This Component
Single-channel optoisolator with 3.75kV isolation rating and transistor output in 4-pin SSOP package. Provides galvanic isolation between input and output circuits using LED/phototransistor coupling. Suitable for gate drive circuits, digital signal isolation, and noise-sensitive applications requiring compact surface-mount form factor.
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.
