Frequently Asked Questions

What is the spectral response of the PT0603AC-LB1-S ambient light sensor?

The PT0603AC-LB1-S sensor features a spectral sensitivity curve that is closely matched to the human eye's photopic response (CIE standard). It includes infrared filtering to minimize the impact of IR light, ensuring measurements are accurate for visible light conditions relevant to display brightness and user perception.

What is the operating voltage and output signal of this sensor?

As a basic photodiode component, the PT0603AC-LB1-S requires an external circuit (such as a transimpedance amplifier) to generate a usable voltage or current signal proportional to light intensity. The specific operating voltage and output scaling depend on the design of the external conditioning circuit implemented on your PCB.

How do I solder and integrate this 0603 sensor onto my PCB?

This sensor is supplied in a standard 0603 surface-mount device (SMD) package. It is designed for reflow soldering processes common in PCB assembly. Ensure your PCB layout includes appropriate pad geometry for a 2-pin 0603 component and follow standard ESD handling procedures during placement to prevent damage to the sensitive photodiode element.
