Bourns BSD series silicon carbide schottky barrier diode

Bourns is pleased to expand its model BSD Series Silicon Carbide (SiC) Schottky Barrier Diode (SBD) product family. These new BSD models 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. The 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 650V and 1200V voltage operation with currents in the from 5A to 10A 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, TO263 and TO247-2, the ten 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.
