Automotive Rectifiers from Diodes Incorporated Provide up to Ten Times Greater Avalanche Capability


ir

PLANO, TX--July 24, 2013: Diodes Incorporated , a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today introduced a family of its Super Barrier Rectifiers (SBR) qualified to the AECQ101 high-reliability automotive standard and backed by PPAP level 3 documentation. The parts are 100% avalanche tested and proven to deliver a reverse-avalanche capability of between three to ten times greater than competing Schottky alternatives.

Due to the SBR's unique patented structure, its high-reverse avalanche performance ensures greater guardbanding against negative spikes and inductive load surges, thereby raising the ruggedness and reliability of automotive products. In a typical single-pulse avalanche test, avalanche energy measurements for Schottky and SBR devices were respectively 7mJ and 70mJ for the same circuit conditions.

Offering current ratings up to 60A and reverse voltage ratings up to 100V, the SBR 'Q' portfolio is also characterized by significantly lower reverse leakage current at higher temperatures, helping to minimize circuit losses and increasing protection against thermal runaway.

The SBR forward voltage drop is also lower than that of the Schottky, meaning conduction losses are less and overall efficiency is improved in common reverse-polarity protection and freewheeling diode circuits, for example.
