Developing circuits for advanced inverters, converters, or automotive systems? Given the growing customer demands for ever-smaller products, it’s important to consider component size during the design process. New DFN3820A-sized rectifiers and diodes from Vishay Intertechnology make this process a bit easier, thanks to their extremely low profile and compact size. This article explores the new lineup and how they can help you create smaller solutions.

Standard Rectifiers

Industry-first 2 A to 4 A, up to 600 V standard rectifiers in an extremely low-profile DFN3820A size.

Powerful DFN design offers high current density and high-efficiency capability with small and extremely low-profile solutions.

Key Product Features

  • Industry-first Power DFN3820A low profile package with wettable flanks - small dimensions of 3.8 mm x 2.0 mm with typical height of 0.88 mm
  • High current 2 A to 4 A standard rectifiers with high efficiency
  • Compared to the SMP (DO-220AA) package, the DFN3820A more than doubles the performance under thermal equilibrium conditions
  • Oxide planar chip junction design
  • Reverse voltage up to 600 V with typical reverse leakage current less than 0.1 μA and a wide temperature range from -55 °C to +175 °C

Vishay Intertechnology introduces three new series of automotive-grade surface-mount standard rectifiers that are the industry’s first devices in the Power DFN Series DFN3820A package with wettable flanks. Providing space-saving, high-efficiency solutions, the 2 A SE20Nx, 3 A SE30Nx, and 4 A SE40Nx are each available with reverse voltages of 200 V, 400 V, and 600 V.

The first package in Vishay’s new Power DFN family, the DFN3820A’s compact footprint and low profile allow the SE20Nx, SE30Nx, and SE40Nx to make more efficient use of PCB space.

  • The devices’ optimized copper mass design and advanced die placement technology allow for superior thermal performance that enables operation at higher current ratings.
  • Compared to devices in the SMP (DO-220AA) package with the same footprint, the SE20Nx, SE30Nx, and SE40Nx offer a 12% lower profile and double the current rating.
  • The rectifiers offer equivalent or higher current ratings to larger devices in the conventional SMB (DO-214AA) and SMC (DO-214AB) packages, as well as the eSMP® series SlimSMA (DO-221AC), SlimSMAW (DO-221AD), SMPA (DO-221BC), and SMPC (TO-2778).

TMBS® Rectifiers

60 V, 100 V, and 150 V TMBS® rectifiers provide improved thermal performance and efficiency.

Key Product Features

  • Industry-first Schottky rectifiers in extremely low profile (0.88 mm) power DFN3820A with wettable flanks offer best-in-class power density in a 3.8 mm x 2.0 mm footprint.
  • Wettable flanks allow for automatic optical inspection (AOI), eliminating the need for X-ray inspection.
  • A high current rating of up to 7 A is double the power density of other solutions of the same size.

Additional Benefits

  • Current density is 50% higher than conventional SMA (DO-214AC), and 12% higher than SMF (DO-219AB).
  • More efficient use of space on the PCB: an 85% reduction compared to the conventional SMB (DO-214AA) and a 42% reduction compared to the eSMP® Series - SlimSMAW (DO-221AD), and a higher current rating (double), compared to the SMP (DO-220AA).
  • Optimized inner structure design offers superior thermal performance, enabling much higher operating current compared to the SMP (DO-220AA) package in the same footprint, and outperforms conventional Schottky rectifiers in the SMA (DO-214AC) and SMB (DO-214AA) packages.


FRED Pt® Ultrafast Rectifiers in DFN3820A Package with Wettable Flanks

1 A to 5 A, 200 V FRED Pt® rectifiers offer space savings, improved thermal performance and efficiency.

Vishay Intertechnology introduces four new series of 200 V FRED Pt® ultrafast rectifiers in the low profile DFN3820A package with wettable flanks. Providing space-saving, high-efficiency solutions for commercial, industrial, and automotive applications, the 1 A VS-1EAH02xM3, 2 A VS-2EAH02xM3, 3 A VS-3EAH02xM3, and 5 A VS-5EAH02xM3 are each available in automotive grade, AEC-Q101 qualified versions.

  • The first package in Vishay’s new Power DFN family, the DFN3820A’s compact footprint and low profile allow the VS-1EAH02xM3, VS-2EAH02xM3, VS-3EAH02xM3, and VS-5EAH02xM3 to make more efficient use of PCB space.
  • Compared to devices in the SMP (DO-220AA) package with the same footprint, the VS-1EAH02xM3, VS-2EAH02xM3, VS-3EAH02xM3, and VS-5EAH02xM3 offer a 12 % lower profile and more than double the current rating.
  • The devices’ optimized copper mass design and advanced die placement technology allow for superior thermal performance that enables operation at higher current ratings.
  • The rectifiers offer equivalent or higher current ratings to larger devices in the conventional SMB (DO-214AA) and SMC (DO-214AB) packages, as well as the eSMP® series SlimSMA (DO-221AC), SlimSMAW (DO-221AD), and SMPC (TO-2778A).
