3. Performance Specifications
The PA200 Si PIN detector is characterized by a set of well-defined performance parameters that enable engineers to predict its behavior in various operating conditions with confidence. The device typically achieves a dark current of less than 1 nA at a reverse bias of 20 V, which is exceptionally low for a silicon PIN photodiode of its active area. Its rise time is rated at approximately 10 nanoseconds, allowing the detector to respond to fast optical pulses with minimal lag, a critical attribute for time-resolved spectroscopy and LIDAR systems. The spectral responsivity of the PA200 peaks around 900 nm, with a typical value of 0.6 A/W, ensuring efficient conversion of near-infrared light into electrical current. The device also boasts a shatter resistance greater than 100 MΩ, which contributes to its low noise performance and stable baseline during long-duration measurements. The active area of the PA200 is optimized to balance sensitivity with capacitance, resulting in a total capacitance of roughly 10 pF at 20 V reverse bias, which supports high-speed operation without sacrificing signal strength. These specifications are verified through comprehensive testing at Nuchip’s manufacturing facility, and each unit is accompanied by a data sheet detailing its measured performance.
In addition to the core electrical and optical parameters, the PA200 exhibits excellent thermal stability, with minimal drift in dark current and responsivity across a temperature range of −40 °C to +85 °C. This makes the detector suitable for deployment in environments where temperature variations are unavoidable, such as outdoor monitoring stations or industrial process lines. The device also features a high breakdown voltage, typically exceeding 100 V, which provides a generous operating margin and protects against accidental overvoltage conditions. The linear dynamic range of the PA200 extends over several decades of incident power, from nanowatts to milliwatts, allowing it to function effectively in both low‑light and high‑light scenarios without additional attenuation. The noise equivalent power (NEP) is on the order of 10⁻¹⁴ W/√Hz, placing the PA200 among the most sensitive silicon photodiodes available for its class. These performance metrics ensure that the detector can meet the demanding requirements of applications such as X‑ray fluorescence (XRF) analysis, medical imaging, and nuclear physics experiments. For system designers, the availability of detailed SPICE models for the PA200 facilitates accurate simulation of circuit behavior, reducing development time and risk. The combination of low noise, high speed, and broad spectral coverage makes the PA200 a versatile building block for advanced optical systems.
