Photo Diode, 850nm, 75°, T-1 3/4 Package, 2-Pin

The SFH 203 P is a radial T1 3/4 silicon PIN photodiode engineered for precision light detection. Its 850nm peak sensitivity makes it ideal for infrared applications, offering reliable performance in a compact 5mm plastic LED-style package. This component features a remarkably short switching time, typically just 5ns, enabling fast response in critical circuits. It delivers a typical photocurrent of 9.5µA under standard illumination conditions, ensuring efficient signal generation.

Built to operate reliably across a broad temperature spectrum from -40°C to 100°C, this photodiode is suited for demanding environments. It is rated for a maximum reverse voltage of 50V and has a total power dissipation of up to 150mW. An integrated ESD protection of 2kV (HBM, Class 2) safeguards the device against electrostatic discharge, enhancing its durability and lifespan in real-world applications.
