Product Overview

The XL-4543PDC is a XINGLIGHT infrared receiver phototransistor in the LED category. Its package outline is specified as 4.8 x 4.4 x 8.7 x 1.5 mm, using an infrared receiver tube structure with black colloid. The package drawing notes a general dimension tolerance of ±0.25 mm, while belt and disk packaging dimensions use ±0.1 mm tolerance.

Optical and electrical parameters are centered on 940 nm infrared reception. At Ta=25°C, the device has a 700 nm to 1100 nm spectral bandwidth, 940 nm typical peak wavelength, and ±60° typical view angle. Light current is 25 uA minimum, 35 uA typical, and 45 uA maximum at VR=5 V, E=1.0 mW/cm², and λ=940 nm. Dark current is specified at 30 nA maximum with VR=10 V and E=0 mW/cm².

For circuit and assembly planning, maximum ratings include 30 V collector-emitter voltage, 5 V emitter-collector voltage, -20°C to +85°C operating temperature, and -40°C to +85°C storage temperature. The datasheet also specifies MSL 3 handling, RoHS compliance, 260°C for 6 s reflow maximum rating, 300°C for 3 s manual soldering maximum rating, and a recommended 240±5°C for 6 s maximum welding temperature.
