Instructions for Use:
- Power Supply: Ensure that the input voltage (VF) is within the specified range (1.2V to 1.6V) when applying current to the photodiode.
- Current Limiting: Use a current-limiting resistor to prevent the input current (IF) from exceeding 20mA.
- Output Load: The output can handle up to 50mA of collector current (IC). Ensure the load connected to the output does not exceed this limit.
- Isolation: The device provides electrical isolation up to 5000Vrms for 1 minute. Ensure that the input and output circuits are properly isolated to avoid damage.
- Temperature Considerations: Operate the device within the specified temperature range (-40°C to +105°C) to ensure reliable performance.
- Timing Parameters: The rise and fall times are 2μs maximum. Design your circuit to accommodate these timing characteristics.
- Pin Configuration: Connect the pins as follows: Anode (A) to the positive supply, Cathode (K) to ground, Emitter (E) to ground, and Collector (C) to the load.
- Storage: Store the device in a dry place within the storage temperature range (-40°C to +125°C) to maintain its integrity.
