InGaAs PIN Photodiodes

Active Area Diameter 0.8-3 mm; Responsivity 25-36 A/W; Capacitance 2-10 pF; NEP 14-20 fW/√Hz; Dark Current 50, 100 nA; Package TO-5, TO-8Excelitas’ 1064 nm long-wavelength enhanced Silicon Avalanche Photodiodes (APDs) C30954EH, C30955EH and C30956EH are made using a double-diffused “reach-through” structure. The design of these photodiodes is such that their long-wave response (i.e. >900 nm) has been enhanced without introducing any undesirable properties.The C30954EH, C30955EH and C30956EH long-wavelength enhanced APDs have quantum efficiency of up to 40 % at 1060 nm. At the same time, the diodes retain the low-noise, low-capacitance, and fast rise and fall times characteristics.To help simplify many design needs, these APDs are also available in Excelitas’ high-performance hybrid preamplifier module type C30659 series, as well as the preamplifier and TE cooler incorporated module type LLAM series. In addition, these APDs are also available with built-in thermo-electric cooler for easier temperature control.The C30954EH long-wavelength enhanced silicon avalanche photodiode (Si APD) provides a 0.8 mm active area diameter in a TO-5 package.The C30955EH long-wavelength enhanced silicon avalanche photodiode (Si APD) provides a 1.5 mm active area diameter in a TO-5 package.The C30956EH large-area, long-wavelength enhanced silicon avalanche Photodiode (Si APD) provides a 3 mm active area diameter in a TO-8 package.Key Features:Active Area Diameter: 0.8, 1.5, 3 mmHigh Quantum Efficiency at 1060 nm: ≤40%Enhanced Long-wave Response: >900 nmFast Response Time: 2 nsWide Operating Temperature RangeLow Capacitance @100 kHz: 2 to 10 pFResponsivity @1060 nm: 25 to 36 A/WDark Current: 50, 100 nASpectral Noise Current: 0.5 pA/√HzNEP @1060 nm: 14 to 20 fW/√HzVop Range: 275 to 425 VHermetically Sealed Packages: TO-5, TO-8RoHS CompliantTEC Option AvailableCustomization Available Upon RequestApplications: Range Finding; LiDAR (Light Detection and Ranging); YAG Laser DetectionPlease note that Excelitas products are available from us only in Denmark, Finland, Iceland, Norway, and Sweden.

All VTD Series silicon photodiodes exhibit low dark current under reverse bias, fast speed of response and a wide field of view.These photodiodes have been commonly used in many applications as a replacement for competitive devices.The VTD34 series in plastic packages (partly surface-mount) are BPW34(F) industry equivalents and provide excellent sensitivity at low light level. These photodiodes with 7.45 mm² active area are designed for a spectral response between 400 nm and 1100 nm or 725 nm and 1150 nm. Suitable for direct mounting to a printed circuit board (PCB), arrays can be formed by positioning these devices side by side.The VTD31AAH is a silicon photodiode on ceramic substrate coated with clear epoxy, and a CLD31AA industry equivalent. This photodiode provides a low dark current, fast response and wide field-of-view. This silicon photodiode provides a 16.73 mm² active area designed for spectral response between 400 nm and 1150 nm.The VTD205 series are silicon photodiodes in TO-92 side-looker package, clear (VTD205KH) or with visible blocking (VTD205H), and an SFH205(K) industry equivalent. This photodiode series provides a 7.41 mm2 active area, low dark current, fast response, and a wide field-of-view. The devices are designed for spectral response between 800 nm and 1100 nm (VTD205H) or between 400 nm and 1100 nm (VTD205KH).The VTD206 series are silicon photodiodes in TO-92 side-looker package, clear (VTD206KH) or with visible blocking (VTD206H), and an SFH206(K) industry equivalent. This photodiode series provides a 7.41 mm2 active area, low dark current, fast response, and a wide field-of-view. The devices are designed for spectral response between 750 nm and 1100 nm (VTD206H) or between 400 nm and 1100 nm (VTD206KH).Applications: Pulse Oximetry; Automotive; Surface-mount Assembly ProcessPlease note that Excelitas products are available from us only in Denmark, Finland, Iceland, Norway, and Sweden.
