Description
The TLP280 consists of a gallium arsenide infrared LED and a phototransistor within a single package. When the LED is activated by an input current, it emits infrared light detected by the phototransistor, allowing it to conduct and transmit the signal across the isolation barrier.
With a compact SOP (Small Outline Package) design, the TLP280 offers a high level of insulation, typically rated at 2500 Vrms, making it suitable for applications such as power supply units, industrial equipment, and communication devices. Its low input current requirement and fast response time make it efficient for digital signal isolation in various electronic applications.
Equivalent
1. PC817 by Sharp or other manufacturers
2. LTV-817 by Lite-On
3. EL817 by Everlight
4. H11A817 by Fairchild/ON Semiconductor
5. SFH617A by Vishay
These alternatives typically offer similar functionality with variations in input-output isolation voltage, response time, and packaging, so it's important to check the datasheet specifications to ensure compatibility for your specific application.
Features
1. Compact Package: It is housed in a small 4-pin SO6 package, making it suitable for high-density circuit designs.
2. High Isolation Voltage: The device typically offers a high isolation voltage of 3750 Vrms, ensuring robust protection against electrical interference.
3. LED and Phototransistor: It consists of a GaAs infrared LED and an integrated phototransistor, enabling efficient signal transmission with low input current.
4. Wide Operating Range: The operating temperature range is from -55°C to 110°C, which makes it versatile for various environmental conditions.
5. Low Input Current: The low input current requirement allows for energy-efficient operation.
6. Fast Switching Speed: It provides a fast response time, beneficial for high-speed signal applications.
These features make the TLP280 ideal for applications like power supply isolation, signal transmission across different voltage potentials, and noise reduction in electronic devices.
Pinout
1. Pin 1 (Anode): This pin is connected to the positive side of the input LED. It is used to forward-bias the LED, allowing it to emit light.
2. Pin 2 (Cathode): This pin is connected to the negative side of the input LED. It completes the circuit for the LED when connected to ground or a negative voltage.
3. Pin 3 (Emitter): This is the emitter of the phototransistor. It is usually connected to ground or a low-voltage point as part of the output circuit.
4. Pin 4 (Collector): This is the collector of the phototransistor. It is typically connected to the load or a positive voltage. When the input LED is activated, the phototransistor allows current to flow from collector to emitter.
The TLP280 provides electrical isolation by using light to transmit signals between input and output, making it ideal for interfacing different voltage levels or noisy environments.
