C30724EH-2
Stable Gain Silicon Avalanche Photodiode (APD) for High Volume Range Finding
Excelitas’ C30724 series avalanche photodiode is designed for operation at gains in the range 10 to 20. The operating voltage range is 120 to 200 Volts, and in many applications, the APD can be operated at a fixed bias voltage, without the need for temperature compensation.
The C30724 series APDs provide high responsivity in the wavelength range 800 to 950 nm, and rise and fall times of about 5 ns, with no "tail" in the fall time characteristic. They are particularly suited for high volume applications such as Laser Range Finding, Optical Communication Systems and other applications requiring high speed and low noise.
These APDs come in three different packages, designed to meet the needs of high volume and low cost applications.
The C30724EH is in a hermetically sealed TO-18 can. The C30724EH-2 is a modified TO-18 with a built in 905 nm narrow band pass filter. The C30724PH is in a TO-18 plastic encapsulated package.
As the C30724 series intended use is for large volume applications, it is often offered in pair with Excelitas’ high volume plastic encapsulated 905 nm pulsed laser diodes PGEW, DPGEW and TPGEW series. Please inquire about our large volume APD and Pulse Laser pair pricing for your specific application.
