The S15415-05 is a gain-stabilized silicon avalanche photodiode with a built-in temperature compensation function, designed for laser monitoring in optical rangefinders without requiring external temperature adjustment. It features a photosensitive area of φ0.5 mm, a peak sensitivity wavelength of 840 nm at M=50, and a typical cutoff frequency of 500 MHz at λ=905 nm and M=50. The device is packaged in a compact glass epoxy housing measuring 2.0 × 1.8 × 0.85 mm. Operating reverse voltage varies with temperature at a coefficient of 1.1 V/°C, with gain stable between 30 and 100. Dark current is up to 400 pA at M=50, and terminal capacitance is up to 1.1 pF at 1 MHz. It operates from -30 to +105 °C and supports reflow soldering per JEDEC J-STD-020 MSL 2a.
High-speed, compact Si APD that does not require temperature adjustment
The S15415 series is a gain-stabilized APD (GS APD) with a built-in temperature compensation function inside the sensor. This realizes constant gain without the need for temperature adjustment. It is suitable for laser monitors of optical rangefinders used in a wide range of applications, from consumer to industrial.
