Product catalog summary

Overview: The document provides technical specifications and details for the S13955-01, S13956-01, and S13957-01 back-illuminated photodiodes with a Chip Scale Package (CSP) structure. These photodiodes are designed for easy coupling with scintillators, making them suitable for non-destructive X-ray inspection equipment.

Features:

Spectral response range: 400 to 1100 nm.
Package sizes: 7.52 × 7.52 mm (S13955-01), 3 × 3 mm (S13956-01), 5 × 5 mm (S13957-01).
Designed with minimal dead space for side-by-side arrangement.

Applications:

General industrial measurement.
X-ray test equipment.

Specifications:

Maximum reverse voltage: 10 V.
Operating temperature: -20 to +60 °C.
Storage temperature: -20 to +80 °C.
Reflow soldering conditions: Peak temperature of 260 °C.

Electrical and Optical Characteristics:

Spectral response range: 400 to 1100 nm with peak sensitivity at 960 nm.
Photosensitivity at 540 nm: 0.38 to 0.42 A/W.
Short circuit current: Varies by model, e.g., 36 to 46 μA for S13955-01.
Dark current: Varies by model, e.g., 50 to 1000 pA for S13955-01.
Rise time: 15 μs.
Terminal capacitance: Varies by model, e.g., 300 to 700 pF for S13955-01.

Design and Structure:

Photosensitive area dimensions vary by model, e.g., 7.05 × 7.05 mm for S13955-01.
Includes dimensional outlines and recommended land patterns for each model.

Precautions:

Ensure usage within absolute maximum ratings to prevent quality degradation.
Store in environments below 30 °C and 60% humidity, and solder within 24 hours after unpacking.

Disclaimer: Product specifications are subject to change, and the warranty is limited to one year for defects reported within that period. Liability for losses due to natural disasters or improper use is not accepted.

Catalog excerpts

Back-illuminated photodiodes with CSP structure A scintillator can be coupled directly on the chip by using a back-illuminated photodiode. It is designed with minimal dead space around the product. This makes it possible to arrange multiple products side by side. Spectral response range: 400 to 1100 nm General industrial measurement X-ray test equipment Easy coupling with a scintillator Because there are no wires in the photosensitive area and the optical coupling eﬃciency with an scintillator can be maximized, it suitable for non-destructive X-ray inspection equipment.
