The STE221 Series Power Device Analyzer is a comprehensive solution for circuit design, enabling power electronics engineers to select the power devices best suited to their specific applications, thereby maximizing the value of their power electronics products. It is capable of characterizing all relevant device parameters under various operating conditions—including IV parameters (breakdown voltage and on-resistance), FET terminal capacitance, gate charge, and power loss. Designed specifically for circuit design applications, the STE221 Series Power Device Analyzer features full curve-tracer capabilities alongside a host of other functions.
STE221 Series Power Device Analyzer
Key Features
Standard Features of the STE221
A wide operating range of up to 3.5 kV / 1800 A
Fully Automated Rapid Thermal Testing from -50°C to +250°C
Technology for Automatically Generating Technical Documentation for Power Devices (Semiconductors and Components)
The automatic recording function prevents data loss.
AI-Assisted Python Test Script Writing
STE221 IV Kit Features
Enables fully automated, high-speed IV measurements (Ron, BV, leakage, Vth, Vsat, etc.) on packaged devices and wafers
A narrow IV pulse width (as narrow as 10 μs) prevents device self-heating, enabling more accurate testing of the device's actual performance
The Oscilloscope View (Time-Domain View) allows for the monitoring of actual voltage and current pulse waveforms, enabling accurate measurements
Configuration options are flexible (current ranges can be flexibly selected from 20 A up to 200 A, 600 A, or 1800 A), with CV and Qg available as optional features
