Press Release Summary:
Rated 600 V, 60APU06 and 60EPU06 recovery epitaxial diodes have soft recovery current waveshape to reduce or eliminate need for snubber components. Platinum diffusion process controls charge carrier lifetime, and product includes ability to set or adjust diode recovery characteristics. Thermal resistance of 0.63 k/W max, combined with 175°C max allowable junction temperature and 1.42 V forward voltage, results in 60 A current rating at 116°C case temperature.

International Rectifier Introduces Platinum-Diffused Diodes with High Blocking Voltage Characteristics to Enhance Efficiency and Performance
EL SEGUNDO, CA., April 2004 - International Rectifier, IR® (NYSE: IRF) today introduces the 600V-rated 60APU06 and 60EPU06 platinum (Pt) diffused Ultrafast recovery epitaxial diodes. The platinum diffusion process accurately controls charge carrier lifetime. The ability to set or adjust diode recovery (speed) characteristics enables optimized performance and efficiency. Applications for the new diodes include output rectification in industrial switch mode power supplies such as high frequency and AC TIG (tungsten inert gas) welding machines in the 80A to 200A DC output range, where 600V devices are recommended due to voltage spikes. Multiple diodes can be placed in parallel for higher current ratings.
"The new diodes are ideal for high-frequency welding machines. In addition, the high blocking voltage characteristics expand the applications beyond welding, to include power factor correction circuits, uninterruptible power supplies, induction heaters, anti-parallel diodes in motor control and general purpose diodes in any high frequency switching circuit," said Massimo Carbone, Product Manager, Consumer and Industrial Sector Business.
The new diodes expand the IR discrete FRED Pt portfolio, and now include devices with 200V, 300V, 400V and 600V blocking voltages, and 8A to 60A average current ratings at various speeds. The new platinum devices have a 600V rating and a "soft" recovery current waveshape to reduce or eliminate the need for snubber components. Forward voltage and recovery charge characteristics (trr = 34ns) are optimized to allow high current operation at switching frequency above 50kHz. Low forward voltage drop reduces conduction losses and low reverse recovery energy reduces switching losses. All features combine to reduce power dissipation, operating temperature, size and weight, while increasing power supply efficiency and reliability.
The low thermal resistance (0.63K/W max.) combined with a high allowable junction temperature (175°C max.) and a forward voltage of 1.42V results in a 60A current rating at 116°C case temperature.
