The TLP1033A is a high-withstanding-voltage photo-interrupter for digital output. The device combines a high-optical-output Ga As infrared LED with a high-sensitivity, high-gain Si photo-IC. The photo-IC, which supports a wide range of systems (3.3 V to 12 V), enables the device to consume less power than conventional devices. The device also features a narrow slit width and high resolution. The short lead package allows automatic mounting.
Designed for direct mounting on printed circuit boards (positioning pins included)

Frequently Asked Questions
What type of environments can the TLP1033A be used in?
It is suitable for domestic appliances, office equipment (printers, copiers), vending machines, and bank ATMs.
How does the device stabilize after power-on?
The output fluctuates for 100 µs after power-on; a bypass capacitor of up to 0.01 µF should be inserted between V and GND.
What are the operating limitations regarding mounting or use?
It must be mounted on a level surface, and users must ensure chemicals used for cleaning only touch the soldered part of the leads.
Does the TLP1033A output require any external components?
No. It provides a digital output (open-collector) that allows direct connection to logic ICs.
