This document describes the Toshiba TLP1000A and TLP1001A infrared photo‑interrupters, which combine a GaAs LED with a high‑gain Si photo‑IC. The devices are suitable for home electronics, office equipment, and automatic service equipment such as vending machines. Key features include TTL‑compatible digital output, built‑in Schmitt‑trigger, and a low‑level or high‑level output option.
The datasheet lists maximum ratings, recommended operating conditions, opto‑electrical characteristics, mechanical precautions, and positioning guidelines for the shutter and sensor. It also provides graphs of relative output voltage versus distance for both models.
| Maximum Forward Current (Ip) | 50 mA |
|---|---|
| Reverse Voltage (VR) | 5 V |
| Output Current (Io) | 50 mA |
| Power Dissipation (Po) | 250 mW |
| Operating Temperature Range | -25 ~ 85 °C |
| Peak Emission Wavelength | 940 nm |
| Weight (typical) | 0.97 g |
| Threshold Input Current (max) | 2.5 mA |
The devices are rated for a maximum forward current of 50 mA.
They operate from –25 °C to +85 °C.
Soldering should be performed after lead forming, and cleaning chemicals must be used only on the soldered surface.
