Product Overview
XL-PD438C from XINGLIGHT is an LED-category infrared receiver diode supplied in a through-hole transparent colloid/package. The outline dimensions are 6.6 x 4.8 x 3.8 mm, with a general dimensional tolerance of ±0.30 mm unless otherwise specified. The device function is infrared reception, with peak sensitivity specified at 940 nm and a spectral bandwidth range from 400 nm to 1100 nm at 25°C.
Electrical and optical ratings include 150 mW maximum power consumption, 32 V maximum reverse voltage, 0.35 V typical open-circuit voltage, 18 µA typical short-circuit current, and reverse light current of 15 µA minimum and 25 µA typical under the stated 940 nm irradiance condition. Reverse dark current is 5 nA typical and 30 nA maximum at VR=10 V with no irradiance.
Assembly and handling data include MSL 3 classification, RoHS directive compliance, 260°C maximum welding for no more than 6 seconds, and a recommended wave peak welding condition of 240°C for 6 seconds. Manual soldering is specified below 300°C for no more than 3 seconds per terminal using a soldering iron below 25 W.
