Rectifier Diodes

The Ultra Low-IR Schottky-Barrier Diode (SBD) guarantees junction temperature of 175°C. Compared with the conventional low IR series, it offers equivalent VF while IR is reduced to 1/10 or less, enabling a reduced risk of thermal runaway and enhanced reliability at higher temperatures. The Super Low Loss Diode (LLD) series for PFC circuits is an […]

Power Supply Control ICs

The Green Mode PWM-ICs have internal start-up circuits with a 500V/750V rating; low EMI noise by frequency diffusion; linearly reduced switching frequency at light load for low standby power with protection functions. The Green Mode Quasi-Resonant ICs have internal start-up circuits with a 500V rating; intermittent or linearly reduced switching frequency; and protection functions. The […]


Fuji Electric offers a high performance and easy-to-use, easy-to-design planer type power MOSFET achieved by the 2nd generation “Quasi-Plane-Junction” technology. It maintains both low power loss and noise, lower RDS(on) characteristics, more controllable switching dv/dt by gate resistance, smaller VGS ringing waveform during switching, narrow band of the gate threshold voltage, and high avalanche durability.
