Tektronix 371B High Power Curve Tracer

High Power Curve Tracer


The 371B, 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 371B 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.
