Présentation
Description
The TLP283 is an optocoupler (or photocoupler) 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.
### Key Specifications:
- Isolation Voltage: 5 kV (RMS)
- Current Transfer Ratio (CTR): 50% (min)
- Switching Speed: 3 μs (typical)
- Package: SOP-4 (small outline package)
### Applications:
- Digital signal isolation (e.g., in PLCs, microcontrollers)
- Noise suppression in industrial controls
- Power supply feedback circuits
### Advantages:
- Compact, surface-mount design
- High-speed switching
- Reliable isolation for noise-sensitive systems
The TLP283 is ideal for applications requiring safe signal transfer while preventing ground loops or voltage spikes.

Pinout
The TLP283 is a 4-pin photocoupler (optoisolator) with the following functions:
1. Pin 1 (Anode): Input-side LED anode (+).
2. Pin 2 (Cathode): Input-side LED cathode (-).
3. Pin 3 (Emitter): Output-side phototransistor emitter (ground in common-emitter mode).
4. Pin 4 (Collector): Output-side phototransistor collector (output signal).
It provides electrical isolation between input and output, with a typical current transfer ratio (CTR) of 50–600%. Used for signal isolation in digital circuits, I/O interfacing, and noise suppression.
