Bourns Announces the Release of New Silicon Carbide (SiC)Schottky Barrier Diodes (SBDs)Model BSD S

Riverside, California – June 26, 2023 – Bourns is pleased to debut its Model BSD Series Silicon Carbide (SiC) Schottky Barrier Diodes (SBDs) that are designed for today’s more demanding high frequency and high current applications that require increased peak forward surge capability, low forward voltage drop, reduced thermal resistance and low power loss. These advanced wide band gap components are ideal power conversion solutions to help increase reliability, switching performance and efficiency in applications such as DC-DC and AC-DC converters, Switched-Mode Power Supplies (SMPS), photovoltaic inverters, motor drives and other rectification applications. In addition to offering 650 V to 1200 V voltage operation with currents in the 6-10 A range, the new BSD models feature no reverse recovery current to reduce EMI, enabling these SiC SBDs to significantly lower energy losses further increasing efficiency. Providing excellent thermal performance and high power density along with various forward voltage, current and package options that include TO220-2, TO247-3, TO252 and DFN8x8, the six new BSD models give designers the higher power density necessary to match their application specifications while helping them develop smaller, state-of-the-art power electronics.
