Special reminder: This series of products are phototransistors. Please pay attention to the difference from photodiodes.

Comparison of the differences between photodiodes and phototransistors:

Abbreviation: Photodiode -PD Phototransistor -PT.

2. Pin Names: The two pins of a photodiode are the positive and negative terminals, while the two pins of a phototransistor are the collector and the emitter.

3. Chip structure: The photodiode is PN, and the phototransistor is NPN or PNP.

4. Response speed: Photodiodes have a fast response, at the nanosecond level, while phototransistors have a slow response, at the microsecond level.

5. Internal amplification characteristics of devices: Photodiodes do not have internal amplification, while phototransistors do, ranging from hundreds of times to hundreds of thousands of times. Different products have different amplification factors.

6. Output linearity: The output linearity of a photodiode is good, while that of a phototransistor is poor.

7. Photodiodes are generally used in reverse, that is, the negative terminal is connected to the high-level terminal and the positive terminal to the low-level terminal. The flow direction of the photosensitive current is from the negative terminal to the positive terminal. NPN type phototransistors typically have the collector connected to the high-level terminal and the emitter connected to the low-level terminal.
