600V FREDs enhance thermal performance
Taiwan Semiconductor has expanded its line of Fast Recovery Epitaxial Diodes (FREDs).
The new PUUPxJ Seriesare SMPC4.6U-packaged wettable flank devices providing best-in-class efficiency and power density. The series offers a maximum repetitive reverse-voltage (VRRM) rating of 600V with selectable device current ratings (IF) of 3A/600V, 6A/600V, 8A/600V, 10A/600V and 12A/600V. Designed for a range of high-performance applications, the 600V FREDs exceed stringent AEC-Q100 automotive requirements for reliability and manufacturability.
Applications for the PUUPxJ series include switching power supplies and power conversion, DC/DC converters, battery charging systems and off-line LED lighting power supplies, snubbers and freewheeling diodes.
Key features include:
- Fast Switching and Reverse-Recovery Times – Planar FRED technology provides lower junction capacitance and faster trr.
- Low Reverse Leakage – Improves efficiency and offers a more controlled switching response between forward and reverse conduction modes.
- Low Reverse-Recovery Charge – Lowers parasitic ringing and EMC, reduces the need for snubbers; increases switching speed and lowers losses.
- Wettable Flank SMPC4.6U (TO-227A) Package – Ideal for automated placement, meeting automotive board mount testing and AEC-Q qualification testing. High yield manufacturability.
- Excellent Thermal Performance– Low-profile packaging with heat-spreader contacts provides excellent thermal management.
- Global Materials Compliance – RoHS compliant, halogen-free (per IEC-61249-2-21), WEEE, REACH, California Prop. 65, JESD-201 Class 2 Whisker Test and others.
“Our new 600V FRED devices deliver exceptional performance built upon Taiwan Semiconductor’s advanced topology and automotive-quality fabrication processes,” said Vice President, TSC Products, Sam Wang. “With the addition of the PUUPxJseries, TSC now offers the industry’s widest portfolio of FRED devices – all with competitive lead times.”
Design resources include comprehensive datasheets, 3D drawings, PCB layout footprint and spice models for each component in the series. AEC-Q100 qualification is in process.
Prices are $0.25 in OEM quantities. The devices are in stock at distributors Digi-Key and Mouser Electronics.
