Space-Saving 100 V and 200 V Devices Feature Compact 3.85 mm by 2.03 mm Footprint With Low 1 mm Profile

MALVERN, Pa. — Vishay Intertechnology, Inc. expanded its offering of FRED Pt Ultrafast recovery rectifiers with eight new 100 V and 200 V devices in the eSMP series SMP (DO-220AA) package, including the industry's first to offer current ratings to 2 A. Measuring 3.85 mm by 2.03 mm with a low 1 mm profile, the Vishay Semiconductors diodes provide space-saving alternatives to devices in the SMA (DO-214AC).

The 1 A and 2 A rectifiers released today increase power density by providing the high current ratings typically reserved for the SMA package in the smaller SMP, which utilizes 24 % less PCB space. For excellent thermal performance, the devices feature an asymmetric design with a large metal pad for heat dissipation, while their FRED Pt technology enables ultrafast recovery times down to 14 ns at TJ = 25 °C, reduced Qrr to 10 nC, and soft recovery features over the entire working temperature range of -55 °C to +175 °C.

Available in AEC-Q101 qualified versions, the rectifiers feature low forward voltage drop down to 0.69 V, 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 devices offer an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of +260 °C. RoHS-compliant and halogen-free, the diodes are ideal 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 20 weeks for large orders. Pricing for U.S. delivery only starts at $0.07 per piece.
