00 — Overview

What the LTR-323DB does

The LTR-323DB is an infrared emitter and detector featuring fast switching time and high sensitivity. It operates with a reverse voltage of 30 V, a rise time of 50 nsec, and a peak sensitivity wavelength of 900 nm. The device supports an operating temperature range from -40°C to +85°C and handles a power dissipation of 150 mW. With low junction capacitance and high cut-off frequency, it is typically used in applications requiring precise optical signal detection and rapid response times within industrial or consumer electronic systems.
