Overview

The VEMT2023X01 is a high-speed silicon NPN epitaxial planar phototransistor featuring a daylight blocking filter and AEC-Q101 automotive qualification. It is designed in a miniature 2-SMD gull wing package with a 70-degree viewing angle, optimized for detecting infrared radiation in the 830 nm to 950 nm range while filtering out visible light.

Why Choose This Part

This component offers a very low dark current of 1 nA and a collector-emitter breakdown voltage of 20 V, ensuring high signal-to-noise ratios. Its compact 2.3mm x 2.3mm footprint and gull wing leads make it ideal for high-density surface mount PCBs requiring AEC-Q101 reliability.

Applications

Infrared Remote Control Receivers
Utilizes the integrated daylight filter to detect IR signals in environments with high ambient visible light.
Automotive Optical Sensors
AEC-Q101 qualified for use in steering wheel position sensing, rain sensors, and cabin comfort controls.
Industrial Light Barriers
Acts as the receiver in short-range optoelectronic switches and proximity detection systems.
Optical Encoders
Provides high radiant sensitivity for speed and position monitoring in small DC motor assemblies.

Getting Started

To integrate this part, pair it with a matched Vishay IR emitter like the VSMB2943RGX01. Ensure the load resistor (RL) is calculated based on the expected 1 mW/cm2 sensitivity to keep the 50 mA maximum collector current within limits during saturation.
