Tiandian optocoupler TD817 belongs to the optotransistor type optocoupler, with an isolation voltage of 5000VRMS and a collector emitter voltage of 35V. The size is 6.5 * 4.58 * 3.5MM, and the working temperature is -55 ℃ to 110 ℃. It can completely replace the conventional PC817/120 in terms of performance, and has advantages in price, stable quality, complete certification, and packaging types of SOP4 and DIP4. The CTR value is 80-160% in A level, 130-260% in B level, 200-400% in C level, and 300-600% in D level
Widely used in power equipment to isolate high and low voltages. The related terminal product applications include home appliances, temperature control, air conditioning (HVAC), vending machines, lighting control devices, chargers, and swappable power supplies. The signal transmission between circuits to completely isolate the front-end from the load is aimed at increasing safety, reducing circuit interference, and simplifying circuit design.
