Frequently Asked Questions
Q: What is an optocoupler IC and what is it used for?
A: An optocoupler (also called a photocoupler) is an electronic component that transfers electrical signals between two isolated circuits using light. It protects sensitive components such as microcontrollers and logic circuits from high voltages, noise, and transients. Common applications include switching power supplies, motor driver boards, PLC input modules, and microcontroller interface circuits.
Q: Which models are included in this optocoupler assortment?
A: This pack includes: 6N137, PC817, TLP250, TLP559, TLP627, 4N35, 4N25, 6N136, 6N138, MOC3041, MOC3020, MOC3021, HCPL3120, MOC3083, PC817B, and PC817C — covering general-purpose, high-speed, triac-driver, and gate-driver optocoupler types.
Q: Are these optocouplers compatible with standard breadboards and PCBs?
A: Yes. All models in this assortment come in standard DIP (Dual In-line Package) through-hole packages, making them fully compatible with breadboards, perfboards, and custom PCBs for easy prototyping and repair work.
Q: Where are these optocoupler ICs made?
A: These components are made in Mainland China.
