Marktech Optoelectronics, Inc. (“Marktech”) today announced a new family of silicon photodiodes (SiPDs) produced in the United States at Marktech’s Simi Valley, California facility and final-packaged in Japan in collaboration with Optrans Corporation. The devices combine fast response time, high photosensitivity, and low junction capacitance in cost-effective, molded-through-hole plastic packages - bringing precision spectral performance to compact, price-sensitive optical designs.

“Engineers need photodiodes that are tuned for their sensing band and still deliver speed, low noise, and value,” said Barry Jones, Silicon Detector Business Manager at Marktech. “Our latest SiPDs provide tightly targeted spectral behavior - either minimal to no visible response for clean NIR detection at 940 nm or a precise 525 nm peak for blue-green sensing - together with low junction capacitance and fast response that strengthen performance in demanding optical sensing applications.”
Product Highlights
MTD3910GC-F3 & MTD3910G-F3 - NIR 940 nm SiPDs with Minimal/No Visible Sensitivity
- 940 nm Spectral Focus: Peak responsivity at 940 nm with strong suppression of visible light
- Visible-Light Suppression Options:
- MTD3910G-F3: Enhanced filtering; virtually zero sensitivity below 775 nm
- MTD3910GC-F3: No responsiveness below 675 nm and only minute sensitivity between 675–775 nm
- Package: Molded through-hole plastic; small active area for fast response and low junction capacitance
- Applications: Short-run plastic-fiber communications, security sensors, IR camera light sensing, oximetry/PPG, barcode scanners, rangefinders, and IR laser monitoring
- Datasheets:
MTD5052D3 - Blue-Green Optimized SiPD (Peak at 525 nm)
Manufacturing & Quality
- Production Flow: Die fabrication and test in Simi Valley, California (U.S.A.) followed by final packaging in Japan with Optrans Corporation, a partner Marktech considers as the world’s leader in optoelectronic packaging and IR detector production.
- Performance You Can Measure: Each device benefits from Marktech’s comprehensive optical and electrical characterization, ensuring consistent speed, sensitivity, and spectral fidelity across builds
