New series of low-profile ultrafast avalanche rectifiers feature 20-mJ EAS avalanche capability
April 18, 2011 // Paul Buckley
Vishay Intertechnology, Inc., has introduced nine new series of low-profile, surface-mount standard, fast, and ultrafast avalanche rectifiers with 20 mJ EAS avalanche capability and industry-high forward currents up to 4 A in compact, space-saving SMP and SMPC packages.
The AS1Px standard, AR1Px fast, and AU1Px ultrafast rectifiers released today in SMP packages offer a low profile of 1.0 mm. Featuring a profile of 1.1, devices in SMPC packages include the AS3Px and AS4Px standard, AR3Px and AR4Px fast, and AU2Px and AU3Px ultrafast rectifiers. The devices save space in secondary rectifiers and freewheeling diodes for very fast switching of AC/DC and DC/DC converters in high-temperature conditions for consumer, lighting, and automotive applications.
Providing high current density, the AEC-Q101-qualified devices combine their compact packages with high average forward currents. In the SMPC package, the AS4Px and AR4Px are the industry's first standard and fast devices to offer a 4 A forward current, while the AU3Px is the industry's first ultra-fast 3 A device. The AS3Px and AR3Px also feature forward currents up to 3 A, while the AU2Px offers currents up to 2 A. Currents in the SMP package range from 1.0 A for the AR1Px and AU1Px to 1.5 A for the AS1Px.
All nine series offer designers a choice of 200 V, 400 V, 600 V, 800 V, or 1,000 V reverse voltage ratings. The rectifiers feature low forward voltage drop, reverse recovery times as low as 75 ns, leakage current down to 0.3 μA, and very low junction-to-mount thermal resistance of 5 °C/W for the SMPC rectifiers and 15 °C/W for the SMP rectifiers. The devices offer a glass passivated chip junction and are ideal for automated placement.
The new rectifiers feature a rugged maximum operation junction temperature of + 175 °C and an MSL moisture sensitivity level of 1, per J-STD-020. The devices are compliant to RoHS directive 2002/95/EC and WEEE 2002/96/EC, and are halogen-free according to IEC 61249-2-21.
Samples and production quantities of the new rectifiers are available now with lead times of 15 weeks for larger orders.
