Visão Geral
Description
The TLP280-4GB is a photocoupler (optoisolator) from Toshiba, designed for signal isolation in electronic circuits. It features a GaAs infrared LED paired with a phototransistor, providing 4 kV AC isolation (1 min) to protect sensitive components from high-voltage transients.
Key specifications:
- Current Transfer Ratio (CTR): 50–600% (min. 50% at 5 mA input).
- Isolation Voltage: 4 kV (AC, 1 min).
- Switching Speed: 3 μs (turn-on) / 2.3 μs (turn-off).
- Package: 4-pin DIP.
Applications include power supply feedback, industrial controls, and digital logic isolation. The "GB" suffix indicates lead-free compliance (RoHS).
For exact details, refer to Toshiba’s datasheet.
