Keithley SMU optimized for testing SiC, GaN power devices

The Keithley 2470 SourceMeter Source Measure Unit can test materials and devices up to 1,100 V and measure low current with 10 fA resolution. It includes a 5-in. capacitive touch display with the full touch experience to make testing intuitive and minimize the learning curve.

The 2470 is optimized for characterizing and testing a broad range of high-voltage, low-leakage devices, materials, and modules. In addition to SiC and GaN, it’s well suited for use with power MOSFETs, transient suppression devices, circuit protection devices, power modules, batteries, and more. These new capabilities make the 2470 the “go-to instrument” for high-voltage source and low-current measurement applications in the lab and in the manufacturing test rack.

The 2470 represents Keithley’s fourth generation of SourceMeter SMUs and offers a highly flexible, four-quadrant voltage and current source/load coupled with precision voltage and current measurements. This all-in-one instrument has the capabilities of a:
• Precision power supply with V and I readback
• True current source
• Digital multimeter (DCV, DCI, ohms, and power with 6½-digit resolution)
• Precision electronic load
• Trigger controller

Like other members of Keithley’s 2400 family, the new 2470 benefits from the Touch, Test Invent

user interface. As shown below, its simple icon-based menu structure reduces the number of steps required to configure a test by as much as 50% and eliminates cumbersome multi-layer menu structures. Built-in, context-sensitive help supports intuitive operation and minimizes the need to review a separate manual. These capabilities, combined with the 2470’s high versatility, simplify its operation in both basic and advanced measurement applications, regardless of the user’s previous experience in working with SMU instruments.
