1. 1.2mm x 1.2mm Silicon PIN Photodiode for Optical Measurement and Laser Monitoring
This 1.2mm x 1.2mm silicon PIN photodiode is supplied in a hermetic TO-46 can for optical measurement, laser monitoring and OEM sensing development. The source specification identifies a 1.2mm x 1.2mm active area and a 400-1100nm spectral response range.
It is a component for optical-system design. The response of a finished instrument depends on the incident wavelength, reverse bias, front-end circuit, optical geometry, ambient conditions and system-level calibration.
2. 400-1100nm Spectral Response and Wavelength-Specific Responsivity
At VR = 5V, the source lists typical responsivity of 0.07mA/mW at 405nm, 0.35mA/mW at 650nm, 0.50mA/mW at 850nm and 0.20mA/mW at 1064nm.
Use these as source-specific reference points rather than assuming identical response across the full spectral range. Wavelength, optical coupling and the intended readout circuit should be evaluated together.
3. Active Area, Response Time and Electrical Conditions
The source lists 15ns typical response time at RL = 50Ω and VR = 5V. It also lists 0.5pA typical dark current at VR = 0V, 150pA typical dark current at VR = 5V, 500pF typical capacitance at VR = 0V and 6pF typical capacitance at VR = 5V, measured at 1MHz.
The specified operating reverse-voltage range is 0-10V, with 15V maximum reverse voltage. The source lists 5mW saturation optical input at VR = 0V and 15mW at VR = 5V; final operating limits must be validated in the intended circuit and optical system.
4. Hermetic TO-46 Package and Configuration Planning
The source describes a standard hermetic TO-46 can. Pin configuration, lead arrangement and any optional receptacle or fiber-coupling requirement must be confirmed for the individual project rather than assumed from the package name alone.
Confirm the required active-area alignment, bias condition, package interface, circuit input impedance and mechanical envelope before selecting the photodiode for production evaluation.
5. Optical Measurement, Laser Monitoring and Industrial Sensing Applications
This silicon PIN photodiode can be evaluated for optical power measurement, laser monitoring, industrial photoelectric sensing and fluorescence-detection research where the source-specified spectral response and package configuration fit the intended design.
The final system designer is responsible for optical coupling, electrical noise, saturation margin, calibration, safety and application-specific validation.
6. Evaluation, Documentation and Custom Development Support
For early-stage electrical and optical evaluation, a 10 pcs / KIT evaluation quantity can be requested with the intended wavelength, reverse-bias condition and readout-circuit information.
For pin configuration, package interface, active-area alignment, optical coupling or project-specific documentation requirements, submit the application conditions and target operating parameters for engineering review.
7. Frequently Asked Questions
FAQ 1. What wavelength range is specified for this silicon PIN photodiode?
The source specification lists a 400-1100nm spectral response range, with typical responsivity reference points at 405nm, 650nm, 850nm and 1064nm under VR = 5V.
FAQ 2. How should I use the listed responsivity values?
Use them as source-specific values under the stated test condition. The final signal depends on wavelength, optical coupling, bias, front-end circuitry and system calibration.
FAQ 3. Is the TO-46 package supplied in one fixed pin configuration?
The hermetic TO-46 can is the package form. Pin arrangement and optional interface requirements must be confirmed for the individual project.
