Fast Recovery Epitaxial Diode Module Littelfuse IXYS MEE250-12DA with Isolation Voltage up to 3600 Volts
Product Overview
This series of Fast Recovery Epitaxial Diode (FRED) Modules, including models MEA 250-12DA, MEK 250-12DA, and MEE 250-12DA, offers high reliability circuit operation with a repetitive peak reverse voltage (VRRM) of 1200 V and an average forward current (IFAVM) of 260 A. Designed with a DCB ceramic base plate and planar passivated chips, these modules feature short recovery times, low switching losses, and soft recovery behavior. They are suitable for applications such as antiparallel diodes for high-frequency switching devices, free-wheeling diodes in converters and motor control circuits, inductive heating and melting, uninterruptible power supplies (UPS), and ultrasonic cleaners and welders. The design contributes to low voltage peaks for reduced protection circuits, low noise switching, and low losses.
