Latham, NY & Simi Valley, CA — November 21, 2025 — 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.”
MTD3910GC-F3 & MTD3910G-F3 — NIR 940 nm SiPDs with Minimal/No Visible Sensitivity
MTD5052D3 — Blue-Green Optimized SiPD (Peak at 525 nm)
