High efficiency + Low noise

Overview

ROHM high efficiency fast recovery diodes feature low noise and minimal loss. Ideal for free-wheel PFCs and IGBTs.

Features

  • Low heat generation and noise during normal operation
  • Low VF, high-speed trr, and soft recovery characteristics ensure high efficiency operation with low loss
