SFH 2240 A01

SFH 2240 A01

ams OSRAM AG
Photodiode 620nm 90ns 120° 2-SMD, No Lead
Active1,217 in stock

Overview

The SFH 2240 A01 is an AEC-Q102 qualified silicon photodiode designed with a spectral sensitivity specifically adapted to match the human eye (V-lambda). It features a wide spectral range from 400nm to 690nm and provides high linearity with a fast 90ns response time. This sensor is ideal for ambient light sensing and display brightness control in demanding environments.

Why Choose This Part

This photodiode offers a high responsivity of 0.37 A/W at 550nm and a low dark current of 1nA, ensuring high signal-to-noise ratios even in low-light conditions. Its surface-mount package supports high-temperature operation up to 125 degrees Celsius and features a very low temperature coefficient of spectral sensitivity.

Applications

Automotive Interior Lighting
Adjusting dashboard and infotainment brightness based on ambient cabin light levels using its AEC-Q102 qualification.
Smart Lighting Control
Daylight harvesting and automatic dimming in industrial or commercial luminaires to maintain constant lux levels.
Rain and Light Sensors
Integrated windshield sensor modules for automatic wiper and headlamp activation.
Display Backlight Dimming
Optimizing power consumption and readability for outdoor displays and handheld instrumentation.

Getting Started

To evaluate this photodiode, integrate it with a transimpedance amplifier (TIA) circuit to convert the nano-ampere level photocurrent into a measurable voltage. Ensure the use of low-leakage PCB design techniques and consider a reverse bias up to 16V to minimize junction capacitance for high-speed switching applications.
