Rectifier Diodes

Fuji Electric's rectifier diodes have features such as low VF characteristics and low IR, and are compatible with PFC circuits of power supplies and secondary-side rectification circuits.

Include maintenance models Include discontinued models


Fuji Electric's rectifier diodes are used in a wide variety of fields including vehicle-mounted applications and public welfare and industrial equipment applications.

SBD (Schottky Barrier Diode):

High temperature operation is possible via a Tj=175°C guarantee, and we have a line-up that includes the "Low IR Schottky Series" capable of reducing the risk of thermal runaway.

LLD (Low Loss Diode):

These diodes are characterized by their low noise as a result of soft recovery and low loss via low VF characteristics.
Our line-up includes: - Super LLD2 Series (for criticality mode PFC)
- Super LLD3 Series (for continuous mode PFC)
These products contribute to the high efficiency operation of power supplies.
