This HCPL-817 opto-isolator provides a single isolated channel for letting a simple microcontroller switch an external load. It is useful when you want to separate low-voltage control electronics from circuits driving relays, small motors or similar loads.
The device comes in a 4-pin DIP through-hole package, making it straightforward to use on a breadboard, prototyping board or custom PCB. It can switch up to 50mA on its output channel.
Sold as an individual unit. A datasheet and example schematic are available from the supplier documentation.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- through-hole
- A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
