MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) this week introduced 10 new FRED Pt® Gen 5 600 V Hyperfast and Ultrafast rectifiers. Offering the best reverse recovery performance for devices in their class, the 15 A, 30 A, 60 A, and 75 A Vishay Semiconductors rectifiers are designed to increase the efficiency of AC/DC and DC/DC converters and of hard- and soft-switched or resonant designs.
The devices released today offer 30% lower reverse recovery losses than the closest competing rectifiers and 48% lower than previous-generation FRED Pt solutions while maintaining low conduction and switching losses. The result is improved light- and full-load efficiency in high-speed LLC output rectification stages for EV/HEV battery charging stations and high frequency stages for UPS applications.
The rectifiers are available in TO-220AC and TO-247AD packages and X-type Hyperfast and H-type Ultrafast speed classes. X-type devices offer the advantage of lower QRR, while H-type rectifiers feature lower forward voltage. RoHS-compliant and halogen-free, the components offer high-temperature operation to +175°C.
Device Specification Table:
|Part #||VR (V)||IF(AV) (A)||VF typ. (V)||QRR typ. (nC)²||Speed class||trr typ. (ns)³||Package|
¹IF = rated current, TJ = 125°C
²TJ = 125°C, IF = rated current A, VR = 400 V, dIF/dt = 1000 A/μs
³TJ = 25°C IF = 1 A dIF/dt = 100 A/μs, VR = 30 V
The Company states samples and production quantities of the new FRED Pt rectifiers are available now, with lead times of 12 weeks.
