Long Xin Da PN66MQ Silicon Photodiode Datasheet

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.
