- Product Introduction
Overview and Features
The Tektronix 371A Curve Tracer is the world standard for high resolution curve tracers and is used in a wide variety of applications. This Curve Tracer performs DC parametric characterization of thyristors, SCRs 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 for testing On-characteristics. It also permits high power testing up to 3,000 watts. In the R&D lab, the Tektronix 371A Curve Trace is used for characterization of new designs, extraction of SPICE parameters, failure analysis and data sheet generation. In manufacturing test, it is used to verify device quality and process monitoring. The Tektronix 371A Curve Tracer is used for incoming inspection to verify device performance, perform failure analysis and to match components.
