The Silicon Carbide (SiC) UV APD has many of the properties of other APDs in that it is extremely sensitive and has high signal gain, but is only sensitive to UV (see wavelength response curve above). Because the substrate is tougher SiC, the bias voltage is higher than silicon based devices, around 180 VDC. These SiC UV APDs are a solid state replacement for UV PMTs (Photo Multiplier Tubes). Besides responding only to the UV, the tough silicon carbide (SiC) provides:
Stability in high energy UV applications
Higher temperature stability than silicon
The general specifications are:
Sensitivity: 1 nW/cm2
Gain: 105 – 106
Bias Voltage: ̴180 VDC
APD Chip Size: 1.2mm2
Active Area: 0.0044 mm2
Package: QFN-16 (4mm x 4mm); Pin 11 + Positive, Pin 2 – Negative
The SiC UV APD is ideal for a variety of low UV light applications including:
Flame detection
UV photon counting
Low level UV monitoring
