Instructions for Use:

1. Handling and Storage:

   • Store the TEPT4400 in a dry, cool place within the specified storage temperature range (-40°C to 85°C).
   • Handle with care to avoid damage to the leads or body.

2. Electrical Connections:

   • Ensure that the forward current (IF) does not exceed 20 mA to prevent damage.
   • Apply reverse voltage carefully, ensuring it does not exceed the reverse breakdown voltage of 5V.

3. Optical Alignment:

   • For optimal performance, align the device so that the target is within the viewing angle of 10° to 20°.

4. Thermal Management:

   • Keep the operating temperature between -40°C and 85°C. Consider heat dissipation methods if operating near the upper limit.

5. Mounting:

   • Follow standard surface mount technology (SMT) procedures for mounting on PCBs. Ensure proper soldering to maintain electrical and thermal integrity.

6. Testing:

   • When testing the device, use the typical parameters as reference points. Measure the forward voltage at 20 mA and check the radiant intensity for expected values.

7. Applications:

   • Suitable for applications requiring infrared detection such as proximity sensors, reflective object detection, and other similar uses.
