Pinout
The TLP290GB is a 4-pin photocoupler (optoisolator) with the following functions:
1. Pin 1 (Anode) – LED anode (input side).
2. Pin 2 (Cathode) – LED cathode (input side).
3. Pin 3 (Emitter) – Phototransistor emitter (output side).
4. Pin 4 (Collector) – Phototransistor collector (output side).
It provides electrical isolation (up to 3750Vrms) and transfers signals via an infrared LED and a phototransistor. Common applications include signal isolation in power supplies, industrial controls, and digital circuits.
Key features:
- Compact DIP-4 package
- High isolation voltage
- Low power consumption
