Photosensor with front-end IC S14137-01CR Compact 16-element APD array suitable for various light level detection (parallel output) The S14137-01CR is a compact optical device that integrates a 16-element APD array and a preamp. The incident light pulse is converted into a voltage pulse, and then the converted pulse is output. It has a built-in DC feedback circuit for reducing the effects of background light. The parallel output 16-element array enables simultaneous measurement of all pixels. Distance measurement (e.g., LiDAR) High-speed response: 180 MHz Reduced background light effects Small waveform distortion when excessive light is incident Structure Parameter Detector Photosensitive area (per element) Element pitch Number of elements Number of output Package Specification Si APD array 0.15 × 0.43 0.5 16 16 Plastic Absolute maximum ratings Parameter Supply voltage (for preamp) Reverse voltage (for APD) Photocurrent (DC) Incident pulse light level Operating temperature Storage temperature Soldering temperature*2 Symbol Condition Vcc max V_APD IL max Ppulse Topr No dew condensation*1 Tstg No dew condensation*1 Tsol *1: When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability. *2: Reflow soldering, JEDEC J-STD-020 MSL 3, see P.8 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.

Photosensor with front-end IC Handling of the temperature characteristics of the APD gain The gain of the APD built into the photosensor with front-end IC varies depending on the temperature. The following two methods are available for handling this issue in using the sensor over a wide temperature range. Temperature compensation method that controls reverse voltage according to temperature changes Place temperature sensor such as a thermistor near the APD to measure the temperature of the APD. The reverse voltage after APD temperature correction is expressed by the following equation using temperature...
