Broadband UV Photodiode – SG01D-5ISO90
Dual-Lead Compact UV Photodiode with ISO90 Encapsulation for Rugged Industrial, Aerospace, and Scientific Applications
The SG01D-5ISO90 is a Silicon Carbide (SiC) broadband UV photodiode designed in a dual-lead package with ISO90 encapsulation, combining compact size with enhanced environmental resistance. With a responsivity peak of 0.13 A/W at 280 nm and a responsivity range from 221–358 nm, it ensures precise ultraviolet-only detection while completely rejecting visible and infrared interference. Its compact 0.03 mm² active area, paired with an integrated ISO90 protective layer, improves stability in harsh conditions. Ultra-low dark current of 0.1 fA and capacitance of 7 pF ensure low-noise, fast-response operation with excellent signal-to-noise ratios. Operating across −55 °C to +170 °C, the SG01D-5ISO90 is engineered for demanding environments. Applications include flame detection, UV curing process monitoring, solar and ozone research, sterilisation validation, and aerospace sensing. Rugged dual-lead packaging combined with ISO90 encapsulation makes this photodiode a reliable choice for long-term, mission-critical ultraviolet detection across industries.
Understanding Broadband UV Photodiode - SG01D-5ISO90
