Product Description

Vishay TEFT4300 is a silicon NPN infrared phototransistor housed in a 3mm (T-1) through-hole package with a daylight filter that blocks visible light to enhance infrared detection precision.

This 2-pin phototransistor offers a wide viewing angle of 60 ° and supports fast switching with typical rise and fall times of 2 μs and 2.3 μs respectively, enabling accurate optical sensing in diverse environments.

The device operates efficiently over an extended temperature range from -40 °C to +100 °C, ensuring robustness for industrial, laboratory, and manufacturing uses. Its electrical limits include a collector current of up to 50 mA and collector-emitter voltage up to 70 V, supporting reliable performance in optoelectronic circuits.

Typical applications include optical switches, counters, sorters, encoders, and position sensing in automated machinery and instrumentation systems. The black plastic T-1 package blocks ambient visible light using a daylight filtering technology.

High radiant sensitivity enhances its detection capabilities in infrared light spectrums. Compact size: diameter 3 mm, height 4.5 mm, width 3.9 mm, length 3.2 mm. Bipolar NPN transistor in through-hole format facilitates easy PCB integration.
