Instructions:

1. Mounting: Ensure the PDTC143ET,215 is mounted on a PCB with appropriate soldering techniques to avoid damage.
2. Current Limitation: Do not exceed the peak forward current (Ifm) of 100mA for more than 1ms to prevent overheating and potential failure.
3. Operating Environment: Operate within the specified temperature range (-40°C to 85°C) to ensure reliable performance.
4. Storage Conditions: Store in a dry place within the storage temperature range (-40°C to 100°C).
5. Electrical Connections: Connect the device ensuring correct polarity; observe the forward voltage (Vf) and reverse current (Ir) ratings.
6. Optical Considerations: For optimal light emission, operate at the typical forward current (If = 20mA) and within the viewing angle (20° to 40°).
