ams OSRAM Phototransistor SFH 3710-3/4 120° Infrared Ultraviolet Visible Light Surface Mount 2-Pin SFH 3710-3/4

ams OSRAM SFH 3710-3/4 is a high-sensitivity phototransistor designed for detecting infrared, ultraviolet, and visible light within a 120° angle of half sensitivity. This surface-mount device features a 2-pin package suitable for compact PCB layouts in industrial and electronic applications.

With a maximum light current of 570μA and minimal dark current of 3nA, it supports precise ambient light sensing, exposure measurement, and control circuits for backlight dimming. Its wide temperature range (-40°C to 85°C) ensures stable operation in diverse environmental conditions.

The phototransistor complies with JEDEC J-STD-020D.01 standards and has compact dimensions (2.1mm length, 0.75mm width, 0.9mm height), making it ideal for integration into modern electronic devices. Its low emitter-collector voltage of 0.5V and collector-emitter voltage of 5.5V support efficient circuit design.

Common industrial and commercial uses include ambient light detection, exposure meters for daylight and artificial light, and sensor systems for display backlight control and drive circuits. This device is part of the SFH 3710 series, known for improved V lambda characteristics matching human eye sensitivity.

Detects infrared, ultraviolet, and visible light spectrums effectively. Wide 120° angle of half sensitivity ensures broad detection coverage. Compact surface mount 2-pin package for easy PCB integration. Operating temperature range from -40°C to 85°C for diverse environments.

High maximum light current of 570μA for precise sensing. Complies with JEDEC J-STD-020D.01 for reliability and quality. Small dimensions optimize space in electronic designs. Used in ambient light sensors, backlight dimming, and exposure measurement applications.
