eSMP® Avalanche Rectifiers

Vishay introduces nine 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 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 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.
