Overview
The B340A-13-F-81 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 a continuous forward current of 3 A. The device exhibits a low forward voltage drop, typically 500 mV at 3 A, with a maximum reverse leakage current of 500 µA. It supports a non-repetitive peak forward surge current of 100 A and operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Low forward voltage drop for high efficiency
- Guard ring structure for transient protection
- Molded plastic case suitable for automated assembly
Applications
- Low voltage high frequency inverters
- Free wheeling diodes
- Polarity protection applications
Procurement Notes
Verify the specific suffix '-81' against official Diodes Incorporated documentation to confirm if it denotes a unique packaging variant or tape-and-reel specification distinct from the standard 'B340A-13-F'. Ensure the component matches the SMA (DO-214AC) footprint and lead finish requirements for your PCB design. Cross-reference the manufacturer's latest datasheet to validate any changes in mechanical dimensions or marking codes associated with this specific ordering code.
Selection Notes
Select this component for circuits requiring efficient rectification at low voltages where minimizing power loss is critical. The 3 A current rating and 40 V breakdown voltage make it suitable for DC-DC converters and power supply outputs. Consider the thermal management capabilities of the SMA package and the operating temperature range when designing for industrial or automotive environments.
Part Context
This part belongs to the B340 series of Schottky rectifiers from Diodes Incorporated, designed for surface mount technology. The series offers various voltage ratings and current capacities within compact packages like SMA and SMC. The B340A-13-F variant specifically targets general-purpose rectification needs in consumer electronics and industrial equipment, balancing performance with cost-effectiveness.
Replacement Considerations
Compatible substitutes include the B340Q-13-F (SMC package) for higher current density needs, or the B340LA-13-F (SMA package) which shares similar electrical characteristics but may differ in specific thermal or mechanical tolerances. Verify pinout compatibility and package dimensions before substitution.
