Vishay Intertechnology releases 34 new 600-V rectifiers in six power packages
June 30, 2011 // Paul Buckley
Vishay Intertechnology has launched 34 new 600 V FRED Pt Hyperfast and Ultrafast rectifiers in six power packages. The devices combine fast and soft recovery time with low forward voltage drop and reverse recovery charge, the new devices reduce switching and conduction losses in high-efficiency PFC in SMPS applications.
The devices are offered with 8 A, 15 A, and 30 A forward currents for 200 W to 3 kW power supplies in a wide range of applications, including DCM, CRM, and CCM PFC in SMPS applications, input booster circuits, high-frequency output rectification, freewheeling diodes, and adapters. Typical end products will include desktop PCs, servers, telecom equipment, air conditioners, UPS, industrial motor drivers, and solar inverter systems.
Available in the power TO-220AC, TO-220 FULLPAK, TO-263AB (D2PAK), TO-262 (I2PAK), TO-247AC, and modified TO-247AC packages (in addition to bare die/wafers), the rectifiers feature five forward voltage classes from 1.07 V to 3.40 V at 8 A and 15 A, and 2.0 V to 2.65 V for 30 A devices.
Reverse recovery time at room temperature starts at 17 ns (at IF =8 A, di/dt = 200 A/µs, VR = 390 V), while reverse recovery charge at +125°C starts at 77 nC (at IF = 8 A, di/dt = 200 A/µs, VR = 390 V).
The new rectifiers are part of Vishay's Hyperfast “H” and “X” series and Ultrafast “L” series. In addition, the new “U” series was specifically developed for ultrafast soft recovery time. The devices feature an improved chip design for increased reliability exceeding standard requirements for resistance to moisture and IR stability over time.
The rectifiers offer a max. operating junction temperature of +175°C for a more robust and cost-effective design, and low leakage. Compliant to RoHS Directive 2002/95/EC (the TO-247AC package is completely lead [Pb]-free), the devices are halogen- free according to the IEC 61249-2-21 definition, and designed and qualified according to JEDEC-JESD47.
Samples and production quantities of the new rectifiers are available now, with lead times of 12 weeks for larger orders.
