A curve tracer (parameter analyzer) is an important electronic measurement instrument that inspects and analyzes the characteristics of semiconductor devices. Curve tracers apply a swept voltage to a semiconductor device, such as a transistor or diode, and measure the resulting current to plot its current-voltage (I-V) characteristic curve.
The curve tracer can measure the following parameters
- Forward voltage of diode
- Reverse leakage current
- Saturation current
- Reverse breakdown voltage
- Transistor gain
- Threshold voltage for MOSFETs
- On-resistance for switches and MOSFETs
As power semiconductor devices are designed to handle higher voltages, the required voltage range for curve tracers is also expanding. Matsusada Precision manufactures and sells high-voltage power supplies that can be used as the sweep voltage source for curve tracers.
