TLP1031A is a high-withstanding-voltage photo-interrupter for digital output. It is suitable for domestic electrical appliances, office equipment, trackballs, and position detectors. The device combines a high-optical-output GaAs infrared LED with a high-sensitivity, high-gain Si photo-IC. The photo-IC supports a wide range of systems (3.3 V to 12 V), enabling the device to consume less power than conventional devices. The device also features a narrow slit width and high resolution.
The TLP1031A is a high‑withstanding‑voltage photointerrupter with a GaAs infrared LED and a high‑sensitivity Si photo‑IC. It offers digital open‑collector output, low power consumption, and a narrow 0.15 mm slit for high resolution.
The device is supplied in a compact 7.4 mm × 4.5 mm package, designed for direct PCB mounting with positioning pins. Detailed electrical ratings, recommended operating conditions, and handling precautions are provided for reliable integration into VTRs, printers, scanners, and other electronic equipment.
