The SG01L-E5D is a specialised erythema-weighted UV photodiode optimised to match the human skin response curve to ultraviolet exposure. With its large 10.0 mm² active area, it produces strong photocurrents for accurate solar UV index monitoring and sunburn risk evaluation. The “D” version enhances spectral selectivity, improving measurement precision in safety-critical applications. Featuring ultra-low dark current (0.1 fA) and high capacitance (1000 pF), it provides stable, noise-free signals suitable for real-time monitoring. Silicon Carbide design ensures complete visible blindness, eliminating interference from non-UV wavelengths. Rugged and durable, the SG01L-E5D operates reliably across −55 °C to +170 °C, ensuring long-term stability.
