Description
The TLP281GB is an optoisolator (or optocoupler) from Toshiba, designed for signal isolation in electronic circuits. It features a GaAs infrared LED paired with a phototransistor, providing electrical isolation between input and output (up to 5kVrms).
### Key Features:
- High isolation voltage (5kVrms)
- Compact 4-pin DIP package
- Low power consumption
- Fast response time (3μs max)
- Wide operating temperature range (-55°C to +110°C)
### Applications:
- Industrial control systems
- Power supply feedback
- Digital logic isolation
- Noise suppression in circuits
The TLP281GB is RoHS-compliant and offers reliable performance in harsh environments. Its high CTR (Current Transfer Ratio) ensures efficient signal transmission.
For detailed specs, refer to Toshiba’s datasheet.

Pinout
The TLP281GB is a 4-pin photocoupler (optoisolator) with the following functions:
1. Pin 1 (Anode) – Input LED anode (+).
2. Pin 2 (Cathode) – Input LED cathode (-).
3. Pin 3 (Emitter) – Phototransistor emitter (output ground).
4. Pin 4 (Collector) – Phototransistor collector (output signal).
It provides electrical isolation (up to 5kVrms) and transfers digital signals between circuits while blocking noise. Common applications include logic level shifting, PLCs, and industrial control systems.
