Diodes

The new series of hyperfast-recovery diodes with soft-recovery waveshape are designed to increase performance and power density in power factor correction (PFC) boost circuits for offline switch mode power supplies. The 8, 15, and 30A devices are suitable for power output levels to 1.5kW. The PFC diodes are especially well matched with International Rectifier's advanced planar HEXFET power MOSFETs for hard-switched converters and PFC boost circuit applications.

The 8ETH06, 15ETH06, 30ETH06, and 30EPH06 are 600 volt, hyperfast, very soft-recovery rectifiers with low forward voltage drop and reverse leakage, which are critical parameters needed to reduce conduction and switching losses. The optimized platinum diffusion manufacturing process helps ensure a gentle and spike-free reverse recovery waveshape over a wide temperature range, thus reducing radiated electrical noise. Additionally, the devices have a maximum junction temperature of 175°C, providing a large, safe operating range.

IR offers various combinations of PFC-specific diodes and MOSFETs to accommodate many power levels. The diodes come in TO-220, TO-262, TO-263, and TO-247 packages for easy design-in.
