Instructions for Use:

1. Power Supply:

   • Ensure the forward current (IF) through the LED does not exceed 20 mA continuously.
   • The reverse voltage (VR) across the LED should not exceed 5 V.

2. Output Circuit:

   • The collector-emitter voltage (VCE) should not exceed 70 V.
   • The continuous collector current (IC) should not exceed 50 mA.

3. Current Transfer Ratio (CTR):

   • The CTR can vary from 20% to 400% at IF = 5 mA and VCE = 5 V. Design your circuit to accommodate this range for reliable operation.

4. Timing Parameters:

   • The rise time (tr) and fall time (tf) are both 2 μs under typical conditions (IF = 5 mA, RL = 1 kΩ). Consider these values when designing high-speed circuits.

5. Temperature Considerations:

   • Operate the device within the junction temperature range of -40°C to 100°C.
   • Store the device within the storage temperature range of -40°C to 125°C.

6. Mounting and Handling:

   • Handle the device with care to avoid mechanical damage.
   • Follow standard ESD (Electrostatic Discharge) precautions to prevent damage to the sensitive components.

7. Soldering:

   • Solder the device at a temperature not exceeding 260°C for a duration not exceeding 10 seconds.
   • Allow the device to cool naturally after soldering to avoid thermal shock.

8. Testing:

   • Test the device under controlled conditions to ensure it meets the specified parameters.
   • Verify the CTR and timing parameters to confirm proper operation.

By following these guidelines, you can ensure optimal performance and reliability of the H11A2 photocoupler in your application.
