SMD photo sensor PO170


The PO170 is a photoelectric integrated sensor with a built-in dual-sensitive receiver that is highly sensitive in the visible range and the output current varies linearly with illumination. It is suitable for energy-saving control, automatic sensitization and adaptive control in many fields such as TV sets, security cameras, LCD backlights, digital products, instrumentation, industrial equipment, etc.

PO170 patch, disk mounted. Commonly used package 0603 0805.


1 The dark current is small, the low illumination response, the sensitivity is high, and the current changes linearly with the increase of the illumination;

2 Built-in dual sensitive element, automatic attenuation of near infrared, spectral response close to the human eye function curve;

3 Built-in micro-signal CMOS amplifier, high-precision voltage source and correction circuit, large output current, wide operating voltage range and good temperature stability;

4 Conforms to EU RoHS Directive, lead-free and cadmium free;

typical application:

1 backlight adjustment: TV, computer monitor, LCD backlight, mobile phone, digital camera, MP4, PDA, GPS;

2 energy-saving control: outdoor advertising machine, induction lighting equipment, toys;

3 instruments: instruments for measuring illuminance and industrial control;

4 environmentally friendly alternative: replace traditional photoresistor, photodiode, phototransistor;
