Overview
The B240A-M3/5AT is a high-current density surface-mount Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes the SMA (DO-214AC) package and features a single circuit configuration with a maximum repetitive peak reverse voltage of 40 V. The device supports a maximum average forward rectified current of 2.0 A and a peak forward surge current of 50 A. Electrical characteristics include a maximum instantaneous forward voltage of 0.55 V at 2.0 A and a maximum reverse current of 0.5 mA at rated VR. The component operates within a junction temperature range of -65 to +150 °C.
Feature Summary
- Guardring structure provides overvoltage protection
- Low profile package ideal for automated placement
- Halogen-free, RoHS-compliant, and commercial grade construction
Applications
- Low voltage, high frequency inverters
- Freewheeling applications
- DC/DC converters
- Polarity protection circuits
Procurement Notes
Verify that the ordering suffix /5AT corresponds to the 7500-unit base quantity in 13-inch diameter plastic tape and reel packaging. Confirm compliance with JESD 201 class 2 whisker test requirements associated with the M3 suffix. Ensure the specific revision of document number 89413 matches the required specifications for the production run.
Selection Notes
Select this component for designs requiring low forward voltage drop and high efficiency in compact surface-mount layouts. The SMA (DO-214AC) case offers a balance of current handling and thermal performance. Verify that the 40 V reverse voltage rating aligns with the peak inverse voltage present in the target circuit application.
Part Context
This part belongs to the B230LA-M3 and B240A-M3 series of high-current density surface-mount Schottky rectifiers. The series shares identical mechanical dimensions and thermal characteristics, differing primarily in their maximum repetitive peak reverse voltage ratings. The M3 suffix indicates halogen-free and RoHS-compliant manufacturing standards.
