Renesas REXFET-1 process means better MOSFETs
Renesas Electronics has introduced new 100V high-power N-Channel MOSFETs that are said to deliver industry-leading high-current switching performance for applications such as motor control, battery management systems, power management and charging.
The devices are built using a new MOSFET wafer manufacturing process (REXFET-1) that enables the new devices to reduce on-resistance by 30 percent. The REXFET-1 process also enables the new MOSFETs to offer a 10 percent reduction in Qg characteristics (the amount of charge needed to apply voltage to a gate), and a 40 percent reduction in Qgd (the amount of charge that needs to be injected into the gate during the 'Miller Plateau' phase).
In addition to superior electrical characteristics, Renesas’ new RBA300N10EANS and RBA300N10EHPF MOSFETs are available in industry-standard TOLL and TOLG packages that are pin-compatible with devices from other manufacturers, and 50 percent smaller than traditional TO-263 packages. The TOLL package also offers wettable flanks for optical inspection.
“Renesas has been a leader in the MOSFET market for many years,” said Avi Kashyap, VP of Discrete Power Solutions BU at Renesas. “As we apply our manufacturing muscle to this market, we can provide customers with superior technical products, as well as assurance of supply from multiple high-volume facilities.”
Renesas has combined the new MOSFETs with other compatible devices from its portfolio to offer combinations such as a 48V Mobility Platform and 3-in-1 Electric Vehicle Unit: Inverter, Onboard Charger, DC/DC Converter. These designs are technically vetted system architectures from mutually compatible devices that work together in an optimised, low-risk design for faster time to market.
Renesas offers more than 400 'Winning Combinations' to enable customers to speed up the design process and bring their products to market more quickly.
The RBA300N10EANS and RBA300N10EHPF MOSFETs are available in production volumes now. Renesas is also offering a reference design with application note to help customers shorten design cycles.
