1. 1.2mm x 1.2mm Silicon PIN Photodiode for Optical Measurement and Laser Monitoring
The 1.2mm x 1.2mm Silicon PIN Photodiode is a hermetic TO-46 detector for component-level optical measurement, laser-power monitoring and industrial optical-sensing projects. Its specified 400-1100nm spectral response and wavelength-specific responsivity values give engineers a practical starting point for matching detector response to a selected source wavelength and reverse-bias condition.
2. 400-1100nm Spectral Response and Wavelength-Specific Responsivity
The device has a specified 400-1100nm spectral response range. The responsivity values below are typical at Vr=5V and are intended for wavelength-specific detector selection, not as a substitute for system-level optical calibration.
405nm: 0.07mA/mW typ.; 650nm: 0.35mA/mW typ.; 850nm: 0.50mA/mW typ.; 1064nm: 0.20mA/mW typ. All listed values are at Vr=5V.
3. Active Area, Response Time and Electrical Conditions
The 1.2mm x 1.2mm active area is paired with a typical 15ns response time at RL=50Ω and Vr=5V. Typical dark current is 0.5pA at Vr=0V and 150pA at Vr=5V. The recommended reverse operating-voltage range is 0-10V; the 15V reverse-voltage figure is an absolute maximum rating, not a recommended continuous operating condition.
4. Hermetic TO-46 Package and Configuration Planning
The standard product uses a hermetic TO-46 can package. A 2-pin or 3-pin configuration, window selection and other project-specific mechanical details should be confirmed before final system integration. This keeps the detector-package selection aligned with the intended electrical connection, optical path and assembly process.
5. Optical Measurement, Laser Monitoring and Industrial Sensing Applications
This silicon PIN photodiode is intended for component-level integration in optical power meters, laser monitoring and industrial automation or control equipment. Engineers should evaluate responsivity, reverse bias, optical coupling and the final system's dynamic range under their own source wavelength and measurement conditions.
6. Evaluation, Documentation and Custom Development Support
For early component-level feasibility work, an Evaluation Kit with 10 pcs / KIT can be arranged with the datasheet and source-backed test conditions needed for initial optical and electrical review. Project-specific package configuration and integration requirements can be discussed before a final production configuration is selected.
FAQ 1. What Wavelength Range Can This Silicon PIN Photodiode Measure?
The specified spectral response range is 400-1100nm. Detector selection should still use the responsivity value and reverse-bias condition relevant to the actual source wavelength.
FAQ 2. How Should I Use The Listed Responsivity Values?
The 405nm, 650nm, 850nm and 1064nm values are typical responsivity figures at Vr=5V. They support initial wavelength selection and optical-power estimation; the final system should be verified with the intended source, optical path and electronics.
FAQ 3. Is The TO-46 Package Supplied In One Fixed Pin Configuration?
The standard product uses a hermetic TO-46 can. The 2-pin or 3-pin configuration is confirmed according to project requirements before final integration.
