B340A-13-G

Overview

The B340A-13-G is a surface mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single diode configuration in an SMA (DO-214AC) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 3 A. The device exhibits a typical forward voltage of 450 mV at rated current and a maximum reverse leakage current of 2 mA. It supports a non-repetitive peak forward surge current of 80 A and operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Utilizes Schottky barrier technology for low forward voltage drop and high efficiency
• Features a molded plastic outline with UL94V-0 flammability rating
• Designed for automatic assembly with tin-plated terminals conforming to MIL-STD-208 standards

Applications

• General purpose rectification in consumer electronics
• Power supply input rectification
• Free-wheeling diodes in DC-DC converters

Procurement Notes

Verify the specific suffix 'G' against the manufacturer's official datasheet to confirm compliance with RoHS directives and halogen-free status, as suffixes often denote environmental or material variations. Ensure the SMA package footprint matches the design layout. Cross-reference the part number with authorized distributors to confirm current production status and availability, as component markings may vary by manufacturing lot.

Selection Notes

Select this component when a 3 A current rating and 40 V blocking voltage are required in a compact SMD form factor. The SMA package offers a balance between thermal performance and board space efficiency compared to larger packages. Consider the 450 mV forward voltage for power loss calculations in low-voltage applications. Verify that the operating environment does not exceed the specified junction temperature limits.

Part Context

This part belongs to the B340 series of Schottky rectifiers from Diodes Incorporated, designed for general-purpose switching and rectification. The series includes variants with different voltage ratings and package options. The B340A specifically denotes the 40 V, 3 A configuration in the SMA case. This series is widely used in portable devices and battery-powered applications due to its low profile and efficient switching characteristics.

Replacement Considerations

Compatible substitutes include B340A-13-F and B340AE-13, provided the package type and electrical specifications match the original design requirements. Verify pinout compatibility and thermal resistance values before substitution.
