Overview

The VEMT2023SLX01 is an NPN silicon phototransistor in a miniature side-view surface-mount package. It features a daylight blocking filter matched with 830 nm to 950 nm infrared emitters, making it ideal for proximity and position sensing in high-ambient light environments. This AEC-Q101 qualified component is specifically designed to pair with the VSMB2943SLX01 series emitters.

Why Choose This Part

This sensor offers a high radiant sensitivity and a low dark current of only 1 nA, ensuring a high signal-to-noise ratio. Its side-view, right-angle surface mount package enables a compact 2.3mm height profile for space-constrained PCBs. The daylight blocking filter and wide 70-degree viewing angle make it robust against alignment tolerances while maintaining selective IR detection.

Applications

Automotive Optical Sensors
Used as a detector for steering wheel position, rain sensors, or cabin control interfaces due to AEC-Q101 qualification.
Industrial Encoders
High radiant sensitivity and fast response times enable precise RPM and position tracking in motor feedback systems.
Photo Interrupters
The side-view orientation allows for low-profile mounting in miniature switches and paper detection sensors.
Object Counting
Integrated daylight filter prevents false triggering from visible light in factory automation environments.

Getting Started

When designing with this phototransistor, ensure the collector-emitter voltage does not exceed the 20V maximum breakdown. For optimal performance, align the optical axis with a compatible 860nm or 940nm IR LED, such as the VSMB2943SLX01. Use a standard reflow soldering profile as the package is designed for lead-free processing.
