Features
1. Phototransistor Output: The TLP126 uses a phototransistor as the output component, which responds to the infrared light emitted by the input LED.
2. Isolation Voltage: It offers a high isolation voltage, typically around 5000 Vrms, ensuring effective separation between input and output sections.
3. Compact Package: The device is available in a compact 4-pin DIP (Dual Inline Package), making it suitable for space-constrained applications.
4. High-Speed Performance: It is designed for fast switching applications, with a typical propagation delay time in the microsecond range.
5. Wide Operating Temperature Range: The TLP126 operates efficiently over a wide temperature range, typically from -55°C to +100°C.
6. Low Input Current: It features low input current requirements, enhancing energy efficiency.
These features make the TLP126 suitable for applications like signal isolation in communication devices, power supply feedback loop isolation, and interfacing with microcontrollers.
Pinout
1. Pin 1: Anode - This is connected to the positive side of the input signal or power source to activate the internal LED.
2. Pin 2: Cathode - This is connected to the negative side of the input signal, completing the LED circuit.
3. Pin 3: Emitter - This is the output pin connected to the emitter of the phototransistor, which is activated by the light from the LED.
4. Pin 4: Collector - This is the output pin connected to the collector of the phototransistor. It provides the isolated output signal.
The TLP126 is commonly used in applications like signal isolation, interfacing different voltage levels, and protecting sensitive components from high voltages and surges.
