Reduces 30% of R_ON and achieves reverse recovery time of one-third of existing products

TOKYO — (BUSINESS WIRE) — April 3, 2013 — Toshiba Corporation (TOKYO: 6502) has launched high-speed diodes based on the 4th generation 600V system super junction MOSFET "DTMOSIV" series. Using the latest single epitaxial process, the new series has reduced the R_ON•A (On-resistance per area) by approximately 30%^(Note1) compared to existing products, to achieve the leading level in the industry. ^(Note2) Also, high-speed parasitic diodes achieve a reverse recovery time of approximately one-third that of existing products^(Note3), reducing loss and contributing to improved power efficiency.
