Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the specified range of 4.5 V to 30 V.
   • Connect the positive terminal of the power supply to pin 4 (VCC) and the negative terminal to pin 3 (GND).

2. LED Forward Current:

   • Limit the forward current (IF) through the LED to a maximum of 60 mA to avoid damage.
   • Use a current-limiting resistor to control the LED current.

3. Collector-Emitter Voltage:

   • Do not exceed the maximum collector-emitter voltage (VCE) of 70 V.

4. Collector Current:

   • Ensure the collector current (IC) does not exceed 50 mA to prevent overheating or damage.

5. Isolation:

   • The device provides an isolation voltage (VIORM) of 5000 Vrms for 1 minute. Ensure proper insulation and spacing in your design to maintain this isolation.

6. Temperature Considerations:

   • Operate the device within the ambient temperature range of -40掳C to +110掳C.
   • Store the device in an environment with temperatures ranging from -40掳C to +125掳C.

7. Timing Parameters:

   • The rise time (tr) and fall time (tf) are both 2 渭s (maximum). These parameters are important for high-speed applications.

8. Current Transfer Ratio (CTR):

   • The CTR can vary from 20% to 500% depending on the forward current and collector-emitter voltage. Use this information to design appropriate circuits.

9. Mounting:

   • Mount the device on a PCB with proper spacing to ensure good heat dissipation and mechanical stability.
   • Follow the recommended soldering profile to avoid thermal stress during assembly.

10. Handling:

    • Handle the device with care to avoid static discharge and physical damage.
    • Use appropriate ESD protection when handling the device.

By following these parameters and instructions, you can ensure reliable and efficient operation of the PS2801C-4 optocoupler in your application.
