200V Ultrafast Rectifiers in MicroSMP Increase Density and EfficiencySeptember 23, 2019 by Paul Shepard
Vishay Intertechnology, Inc. today introduced new 200V FRED Pt® ultrafast recovery rectifiers in the eSMP® series MicroSMP (DO-219AD) package, including the industry's first such device to offer a current rating to 2A. Measuring 2.5mm by 1.3mm with a low 0.65mm profile, the 1A VS-1EQH02HM3 and 2A VS-2EQH02HM3 provide space-saving alternatives to rectifiers in the SMA. Also available are commercial versions, the 1A VS-1EQH02-M3 and 2A VS-2EQH02-M3.
The devices released today increase power density by providing the high current ratings typically reserved for the SMA package in the smaller MicroSMP, which utilizes 57% less PCB space. For excellent thermal performance, the VS-1EQH02HM3 and VS-2EQH02HM3 feature an asymmetric design with a large metal pad for heat dissipation, while their FRED Pt technology enables ultrafast recovery times down to 13 ns, reduced Qrr to 11nC, and soft recovery features over the entire working temperature range of -55°C to +175°C.
The AEC-Q101 qualified devices feature low forward voltage drop down to 0.72V at 1A, which reduces power losses and improves efficiency in high frequency inverters, dc-dc converters, freewheeling diodes, and power factor correction in automotive engine control units (ECU), anti-lock braking systems (ABS), and HID and LED lighting, and telecom and industrial power supplies.

The VS-1EQH02HM3 and VS-2EQH02HM3 offer an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of +260°C. RoHS-compliant and halogen-free, the devices are suited for automated placement and allow for automated optical inspection (AOI) in automotive systems.
Samples and production quantities of the new Ultrafast rectifiers are available now, with lead times of eight weeks for large orders. Pricing for U.S. delivery only starts at $0.06 per piece.
