Introduction to Components
- PC817C is an optically isolated linear feedback control device, which is a commonly used model in the PC817 series.
- On the left (pin 1, 2: input terminal, control terminal) is a light emitting diode.
- The right side (pins 3 and 4: output terminal, controlled terminal) is a triode (CE pole).
- The control end and the controlled end are isolated.
Main technical parameters of PC817C
- Control terminal: maximum voltage 5V, maximum current 50mA. The maximum reverse voltage is 6V.
- Controlled terminal: maximum voltage 35V, maximum current 50mA.
- Isolation voltage: 5000V.
- Working temperature: -30℃ ~ +100℃.
CRT (current ratio): 200% to 400%.
[Optimal voltage and current range]
The best voltage of the control terminal is 0.3V~1.4V, and the best current does not exceed 20mA.
- The optimal voltage of the controlled terminal does not exceed 30V, and the optimal current does not exceed 30mA.
