Vishay B240A-E3/61T General Description

The Vishay B240A-E3/61T is a Schottky barrier rectifier designed for applications requiring fast switching, low forward voltage drop, and high efficiency in surface-mount power supplies, reverse polarity protection, and voltage clamping environments. Housed in a DO-214AC (SMA) package, this device combines a compact footprint with high performance parameters suitable for densely populated electronic assemblies. With its robust construction and proven manufacturing quality from Vishay General Semiconductor, the B240A-E3/61T is widely adopted in a range of automotive, consumer, and industrial designs.

Vishay B240A-E3/61T Main Electrical Specifications

The B240A-E3/61T is characterized by the following electrical parameters:

Maximum reverse voltage: 40 V

Continuous forward current: 2 A

These values make the part ideally suited for low-voltage, medium-current applications such as DC-DC converters, polarity protection modules, and secondary rectification stages in switched-mode power supplies. The Schottky technology further ensures fast recovery time and low forward voltage drop, resulting in reduced power losses and enhanced circuit efficiency. When designing for thermal constraints, engineers should reference Vishay's characterization data and verify operation within specified limits to prevent device deterioration.

Vishay B240A-E3/61T Package Information and Physical Dimensions

The B240A-E3/61T comes in a surface-mount DO-214AC (SMA) package, supporting streamlined assembly in automated PCB manufacturing lines. The SMA package provides a balance between current-carrying capability and minimal footprint, supporting applications where PCB area is at a premium yet device ruggedness is necessary. Vishay’s patented folded-frame construction, indicated by the “T” suffix in the device code, adds mechanical reliability and enhances thermal performance—a key consideration for high-density boards and environments subject to mechanical or thermal stress.

Vishay B240A-E3/61T Tape and Reel Packaging Requirements

Engineers and procurement teams selecting the B240A-E3/61T benefit from Vishay’s adherence to industry-standard tape-and-reel packaging for surface-mount products. Specifically, the device is supplied in accordance with EIA standard 481-E, supporting fully automated pick-and-place systems. Vishay determines precise tape cavity dimensions (A₀, B₀, K₀) based on the maximum component size to ensure reliable feeding and placement accuracy. The clearance between device and cavity is tightly controlled, promoting reliable handling and minimizing risk of mispick in high-speed assembly environments.

Vishay B240A-E3/61T Possible Alternative or Replacement Models

When considering the B240A-E3/61T, engineers may need to identify alternatives for design flexibility, sourcing, or cross-referencing. Potential equivalent or replacement models should offer comparable reverse voltage, forward current ratings, and package type. To ensure safe interchangeability, focus on identical or closely matching electrical specifications and packaging requirements, as deviations in thermal characteristics or mechanical dimensions can affect system reliability. Reference Vishay's comprehensive General Semiconductor portfolio and consult specific datasheets when evaluating cross-compatibility for the target application.
