Instructions for Use:
Mounting:
- Ensure the device is mounted securely on the PCB, maintaining proper alignment of the pins.
- Avoid excessive mechanical stress on the leads during soldering.
Soldering:
- Use a soldering iron with a temperature not exceeding 300°C.
- Solder each pin for no more than 3 seconds to prevent thermal damage to the device.
Electrical Connections:
- Connect the collector (C) to the positive supply or load.
- Connect the emitter (E) to ground or the return path of the load.
- The base (B) is typically left unconnected unless external biasing is required.
Handling:
- Handle the device with care to avoid static discharge, which can damage the phototransistor.
- Use an ESD wrist strap when handling the device.
Testing:
- Test the device under controlled conditions to ensure it meets the specified parameters.
- Use a light source with known intensity to measure the photocurrent accurately.
Storage:
- Store the device in a dry, cool place away from direct sunlight and sources of heat.
- Keep the device in its original packaging until ready for use to protect against moisture and static damage.
