ON Semiconductor’s SiC Diodes Offer Higher Efficiency, Power Density and Lower System Costs

650 V silicon carbide Schottky diodes feature superior switching performance and higher reliability

SAN ANTONIO — (BUSINESS WIRE) — February 28, 2018 — ON Semiconductor (Nasdaq: ON), driving energy efficient innovations, has extended its SiC diode portfolio by introducing its newest family of 650 V silicon carbide (SiC) Schottky diodes. The diodes’ cutting edge, silicon carbide technology provides higher switching capabilities with lower power losses and effortless paralleling of devices.

ON Semiconductor’s newly released family of 650 V SiC diodes includes surface mount and through hole packages ranging from 6 Amperes to 50 Amperes (A). All of the diodes provide zero reverse recovery, low forward voltage, temperature independent current stability, high surge capacity and positive temperature coefficient.

The new diodes are aimed at engineers designing PFC and boost converters for various applications including solar PV inverters, EV/HEV chargers, telecom power and data center power supplies while facing challenges to deliver smaller footprints at higher efficiencies.

The 650 V devices offer the combined system benefits of higher efficiency, higher power density, smaller footprints and enhanced reliability. They exhibit a reduced power loss due to the inherent low forward voltage (VF) and no reverse recovery charge of SiC diodes, and hence improved efficiency. The faster recovery of SiC diodes allows for higher switching speeds and therefore reduces the size of magnetics and other passive components, enabling greater power density and smaller overall circuit designs. In addition, the SiC diodes can withstand higher surge currents and deliver stability over their -55 to +175 degrees C operating temperature range.

ON Semiconductor’s SiC Schottky diodes feature a unique, patented termination structure that reinforces reliability and enhances stability and ruggedness. Additionally, the diodes offer higher avalanche energy, the industry’s highest unclamped inductive switching (UIS) capability and lowest leakage currents.

“ON Semiconductor’s new 650 V family of SiC diodes complement the company’s existing 1200 V SiC devices, bringing a broader product range to our customers,” said Simon Keeton, Senior Vice President and General Manager, MOSFET Business Unit, ON Semiconductor. “Utilizing the unique characteristics of wide band gap materials, SiC technology offers tangible benefits over silicon, and their robust construction provides a dependable solution in applications in challenging environments. Our customers will benefit from simplified, better performing, smaller footprint designs as a result of these new devices.”

Packaging and Pricing

The 650 V SiC diode devices are offered in DPAK, TO-220, and TO-247 packages and priced from $1.30 to $14.39 per unit in 1,000 unit quantities.
