This document introduces the optical and electrical parameters of the silicon solar cell PN66MQ, as well as its wide range of applications in measurement instruments, optical instruments, medical instruments, etc. Silicon solar cells have characteristics such as wide spectrum response range, good linearity, high mechanical strength, and good stability.
The PN66MQ is a silicon photodiode produced by Long Xin Da. It features a wide spectral response (250‑1100 nm) with a peak wavelength of 760 nm, high linearity, and a durable metal encapsulation. Key electrical parameters include an open‑circuit voltage of 300 V under illumination, a short‑circuit current of 16 A (E=100 lx), a shunt resistance of about 2.8 × 10¹⁰ Ω, and a junction capacitance of 4300 pF. The device operates from –20 °C to +75 °C and can be stored between –40 °C and +120 °C.
Typical applications cover measurement and optical instruments, medical devices, textile and paper machinery, grain sorting, counterfeit detection, and optical encoders. During soldering the temperature should not exceed 260 °C, and mechanical stress on the pins must be avoided to prevent damage. The photodiode is supplied in metal‑packaged units with a quartz‑glass window and a photosensitive area of 5.7 mm × 5.7 mm. This manual is written in Chinese.
