Teledyne LeCroy Develops the Most Accurate Measurement System for GaN and SiC Semiconductor Analysis

Teledyne LeCroy announced the launch of their new DL-ISO High Voltage Optically Isolated 1 GHz Probe and Power-Device test software, which when combined with their High Definition Oscilloscopes (HDO®) offer the most accurate electrical characterization of gallium nitride (GaN) and silicon carbide (SiC) power semiconductor devices.

For more than thirty years, engineers have used silicon (Si) metal-oxide-semiconductor field-effect transistor (MOSFET) and insulated-gate bipolar transistor (IGBT) power semiconductor devices to produce power supplies and power conversion systems. However, consumers are demanding smaller and lighter power supplies and systems, and governments are mandating higher efficiencies. Wide-bandgap (WBG) materials, such as GaN and SiC, switch more than ten times faster than Si in semiconductor devices, and reduce size and weight while increasing efficiency. However, many engineers are implementing WBG semiconductors for the first time, and they need more measurement bandwidth and more accurate and detailed analysis of the semiconductor devices. The new Teledyne LeCroy DL-ISO High Voltage Optically Isolated Probe provides design engineers with the highest-confidence GaN and SiC power semiconductor device measurements.

The new probe has the best signal fidelity, lowest overshoot and best accuracy — 1.5% when combined with Teledyne LeCroy’s industry-leading 12-bit resolution HDOs, nearly twice as good as the only competitor (more info).
