Description
The Tektronix 371B Curve Tracer offer power and versatility to test the DC characteristics of semiconductor devices. The Tektronix 371B curve tracer combine a simple-to-use front panel, digital acquisition and display, and programmability to serve a variety of application needs.
In the R&D lab, Tektronix curve tracers are used for characterization of new designs, extraction of SPICE parameters, failure analysis and data sheet generation. In manufacturing test, Tektronix curve tracers are used to verify device quality and process monitoring. They are also used for incoming inspection to verify device performance, perform failure analysis and match components.
The Tektronix 371B Curve Tracer, the industry leader in high-power curve tracers, performs DC parametric characterization on a wide variety of power semiconductors including thyristors, SCRs, IGBTs and power MOSFETs. The high-voltage collector mode permits testing the Off-Characteristics of a device up to 3,000 volts. The pulsed high-current collector mode provides output current pulses greater than 400 amps peak to test On-Characteristics and permits high-power testing up to 3,000 watts. In the sweep measurement mode, the Tektronix 371B Curve Tracer automatically constructs a family of curves while stimulating the device with low-duty-cycle pulses. With this capability, power curves can be displayed without excessive heating of the device.
