PS2501 in-line package DIP4
PS2501-1 is an optocoupler switch circuit, whose function is to add forward voltage to pins 1 and 2, and conduction between output pins 3 and 4, which is equivalent to a short circuit.
PS2801C SMD package SOP16
The PS2801-4 optocoupler isolator contains a gallium arsenide light-emitting diode and an NPN silicon phototransistor. PS2801-4 is integrated in plastic SSOP for high-density applications. This package has a shielding effect to prevent the influence of ambient light.
PC817C DIP4
PC817 photoelectric couplers are widely used in computer terminals, SCR system equipment, measuring instruments, photocopiers, automatic ticketing, household appliances, such as fans, heaters and other circuits for signal transmission, so that the front end is completely isolated from the load. The purpose is to increase safety, reduce circuit interference, and simplify circuit design. PC817 is a commonly used linear optocoupler and is often used as a coupling device in various functional circuits that require more precision. It has the function of completely isolating the upper and lower circuits, and does not affect each other.
