B330LA-M3/5AT

Overview

The B330LA-M3/5AT is a high-current density surface-mount Schottky rectifier manufactured by Vishay General Semiconductor. It features a single diode configuration in an SMA (DO-214AC) package. The device supports a maximum average forward rectified current of 3.0 A and a maximum repetitive peak reverse voltage of 30 V. Key electrical parameters include a peak forward surge current of 65 A, a maximum instantaneous forward voltage of 0.50 V at 3.0 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 enhanced overvoltage protection capabilities
• Low forward voltage drop contributes to reduced power losses and high efficiency
• Halogen-free, RoHS compliant construction with matte tin plated leads
• Meets MSL level 1 per J-STD-020 standards for automated placement

Applications

• Low voltage, high frequency inverters
• Freewheeling applications
• DC/DC converters
• Polarity protection circuits

Procurement Notes

Verify the specific ordering suffix /5AT corresponds to the 7500-unit base quantity on a 13-inch diameter plastic tape and reel. Confirm that the M3 suffix indicates halogen-free, RoHS compliant material categorization and compliance with the JESD 201 class 1A whisker test. Ensure the requested part number matches the B330LA variant with a 30 V rating rather than the B340A variant.

Selection Notes

Select this component for designs requiring a 3 A continuous current capability in a compact SMA surface-mount footprint. The low forward voltage characteristic makes it suitable for improving efficiency in low-voltage power conversion stages. Verify that the 30 V reverse voltage rating aligns with the circuit's peak inverse voltage requirements and that the thermal resistance characteristics fit the system's heat dissipation constraints.

Part Context

This component belongs to the B330LA-M3 series of high-current density surface-mount Schottky rectifiers from Vishay General Semiconductor. It shares the same physical SMA (DO-214AC) package and mechanical dimensions as other variants in the family, such as the B340A-M3, which offers a higher 40 V reverse voltage rating while maintaining identical current handling and thermal properties.
