Instructions:

1. Handling and Storage: Store in a dry environment. Avoid exposure to high humidity and direct sunlight.
2. Mounting: Ensure proper heat sinking if operating at high currents. Follow recommended PCB layout guidelines for optimal performance.
3. Electrical Connections: Connect the anode to the positive terminal and the cathode to the negative terminal. Verify polarity before applying power.
4. Pulse Operation: For applications requiring pulse operation, ensure that the peak forward current does not exceed 1.5 A for pulses of ≤ 1 ms and repetition rates ≤ 100 Hz.
5. Reverse Bias: Do not exceed the maximum reverse voltage of 5V to prevent damage.
6. Thermal Considerations: Monitor temperature during operation. High ambient temperatures can reduce the maximum allowable forward current.
7. Optical Alignment: For best performance, align the photodiode with the light source according to the manufacturer's specifications.
