The TLP126 is typically packaged in a 6-pin DIP (Dual In-line Package) format. It is also available in surface mount options like SO-6.

The TLP126 is an optoisolator (optocoupler) with a total of 4 pins. Its pin configuration is as follows:
1. Anode (A): Connects to the input side (LED).
2. Cathode (K): Connects to the ground side of the input LED.
3. Collector (C): Connects to the output side (phototransistor).
4. Emitter (E): Connects to the ground side of the output phototransistor.
Function: The TLP126 provides electrical isolation between the input and output while allowing signals to be transmitted. When a current flows through the input LED (between pins 1 and 2), it activates the phototransistor on the output side (between pins 3 and 4), allowing current to flow from the collector to the emitter. This isolation enhances safety and protects sensitive components in various applications, such as switching power supplies, signal isolation, and data communication.
