Si PIN photodiode S13993

Product catalog summary

Overview: The S13993 is a large-area Si PIN photodiode designed for direct radiation detection, particularly effective for X-rays, gamma-rays, beta-rays, and charged particles. It features high quantum efficiency, high energy resolution, and low capacitance.

Specifications:

Photosensitive area: 10 × 10 mm
Depletion layer thickness: 0.3 mm
Package: Ceramic
Window material: None

Absolute Maximum Ratings (at 25°C):

Reverse voltage (VR): 100 V
Operating temperature (Topr): -20 to +60 °C
Storage temperature (Tstg): -20 to +80 °C

Note: Exceeding these ratings may degrade product quality.

Electrical and Optical Characteristics (at 25°C):

X-ray energy: 50 keV
Dark current (ID) at VR=70 V: 2 to 6 nA
Temperature coefficient of ID: 1.12 times/°C
Cutoff frequency (fc) at VR=70 V, RL=50 Ω, λ=780 nm: 40 MHz
Terminal capacitance (Ct) at VR=70 V, f=10 kHz: 40 to 60 pF

Features:

High quantum efficiency
High energy resolution
Low capacitance

Applications:

Direct X-ray detection
Radiation detection (gamma-rays, beta-rays, charged particles)

Graphs and Data:

Dark current vs. reverse voltage: Illustrates the relationship between dark current and reverse voltage.
Photosensitivity vs. X-ray energy: Shows theoretical and simulated values of photosensitivity across different X-ray energies.
Terminal capacitance vs. reverse voltage: Displays how terminal capacitance varies with reverse voltage.

Precautions: Ensure no dew condensation occurs on the product surface to prevent deterioration in characteristics and reliability.

Warranty: Valid for one year post-delivery, limited to repair or replacement for defects reported within this period. Liability is not accepted for losses due to natural disasters or improper use.

Catalog excerpts

Large-area Si PIN photodiode for direct radiation detection The S13993 is an unsealed type large-area Si PIN photodiode for direct radiation detection. Since the photosensitive area is coated with Al, there is no sensitivity in the ultraviolet to near infrared region. High quantum efficiency Direct X-ray detection High energy resolution R adiation detection (gamma-rays, beta-rays, charged particles, etc.) Structure Parameter Photosensitive area Depletion layer thickness Package Window material Specification 10 × 10 0.3 Ceramic None Absolute maximum ratings (Ta=25 °C) Parameter Reverse voltage Operating temperature Storage temperature Symbol VR Topr Tstg *1: hen there is a temperature difference between a product and the surounding area in high humidity environments, dew condensation W may occur on the product surface. Dew condensation on the product may cause deterioration in charactaristics and relaiablity. Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings.
