Kingbright AP3025PD2BT Surface Mount Photodiode

Kingbright AP3025PD2BT Surface Mount Photodiode delivers superior light-collection efficiency and high-sensitivity infrared detection in a compact 3mm x 2.5mm x 1.1mm package. This photodiode maximizes photocurrent output and optical coupling efficiency. The AP3025PD2BT photodiode features an integrated black diffused lens and a daylight filter, and effectively blocks ambient visible light interference. This photodiode offers a significantly larger die and expanded active area compared to standard 0805 photodiode packages. The AP3025PD2BT photodiode operates across a spectral bandwidth of 670nm to 1070nm with peak sensitivity at 940nm. Typical applications include machine vision and Automated Optical Inspection (AOI) systems, high-sensitivity infrared sensing systems, industrial optoelectronic switches, and optical touch sensors.

The AP3025PD2BT photodiode is designed to seamlessly pair with IR emitter series including APD3224SF7C (850nm), AM2520SF6C09 (860nm), APD3224SF4C (880nm), APTD1608F3C (940nm), and APD3224F3C (940nm). This photodiode provides high-signal reliability for dense, precision-sensing applications. The AP3025PD2BT photodiode is optimized for high-speed automated assembly and carries a Moisture Sensitivity Level (MSL) 3 rating.
