Industry-Leading Forward Voltage vs Temperature

Wolfspeed’s new 6th-generation (C6D) Silicon Carbide Schottky diode family offers best-in-class forward voltage drop (VF = 1.27V @ 25°C and 1.35 V @ 125°C) across the entire operating temperature range, significantly reducing conduction losses and enabling extremely high system level efficiency. Based on our industry-leading 150mm wafer technology, the C6D diode family increases power density in the most demanding power conversion applications, such as Power Factor Correction (PFC) and High Voltage DC/DC Converters.

Highest Efficiency in Real-World Applications

In high power applications like this boost converter, every fraction of a percent matters.

Instant Upgrade From 3rd Generation (C3D)

Low Forward Voltage (VF) with Improved Thermal Stability

Improved System Level Efficiency (PFC Boost Applications)
