Revolutionary SiC Photodiodes for Superior Deep UVC Detection
Marktech’s new SiC photodiodes are engineered to provide high sensitivity for accurately detecting deep UVC wavelengths. Their wavelength sensitivity range is 220 nm to 358 nm, ideal for applications requiring stringent monitoring and control of UVC light sources. Their visible light or solar blind properties ensure they are unaffected by ambient light, allowing precise UVC measurements without interference.

These new UVC detectors are available in two hermetic package types:

• TO-46 metal can – part number MT12-001
• ATLAS hermetic surface mount (SMD) package - MTSM1057SMF2-046

The hermetic characteristics of TO-can and our proprietary ATLAS package protect the compound semiconductor photodiode chip from the damaging effects of moisture, oxygen, gases, and other vapors – ensuring consistent performance over a long lifetime.

Key Features and Benefits of the New SiC Photodiodes

• Solar Blind Characteristics: These photodiodes are insensitive to visible and solar light, ensuring accurate detection of UVC light in diverse environmental conditions.
• High Sensitivity and Precision: The SiC material enables exceptional sensitivity and precision in detecting deep UVC wavelengths, enhancing the effectiveness of UVC monitoring systems.
• Broad Application Range: Ideal for use in air and surface sterilization, water purification, and analytical instrumentation, these photodiodes support various critical applications that require reliable UVC detection.
• Durability and Reliability: Designed for long-term use, Marktech’s SiC photodiodes offer robust performance with high resistance to environmental degradation.
