Peak power: 3000 W Peak voltage: 3000 V Peak current: 400 A The Tektronix 371 is the industry leader in high power curve tracers is used for testing a wide variety of power semiconductors. The Tektronix 371 performs DC parametric characterization of 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 for testing On-Characteristics.
