The TLP1029 is a digital output photointerrupter that combines an infrared LED with a high‑gain Si photodiode. It offers a fast switching time, large output current and a built‑in Schmitt trigger, making it suitable for direct connection to microcontrollers or logic ICs.
The document lists maximum ratings, recommended operating conditions, detailed electrical characteristics, and handling precautions such as soldering guidelines and chemical compatibility for the device package.
| Supply Voltage (Vcc) | 4.5 V – 17 V |
|---|---|
| Forward Current (Ip) | 50 mA |
| Reverse Voltage (VR) | 5 V |
| Switching Time (tpLH / tpHL) | tpLH = 6 µs, tpHL = 3 µs (typ.) |
| Operating Temperature Range | -25 °C – 85 °C |
| LED Forward Current (recommended) | 21 mA – 25 mA |
| Threshold Input Current | ≤ 6 mA |
The device operates with a supply voltage between 4.5 V and 17 V.
Typical switching times are tpLH = 6 µs and tpHL = 3 µs.
A forward current of 21 mA to 25 mA is recommended.
Soldering should be performed after lead forming.
