Overview
The B340A-E3/5AT is a Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum average forward rectified current of 3 A and a maximum repetitive peak reverse voltage of 40 V. The device utilizes the DO-214AC (SMA) surface-mount package. Key electrical parameters include a maximum DC blocking voltage of 40 V, a peak forward surge current of 80 A, and a maximum non-repetitive peak forward surge current of 75 A. The forward voltage drop is specified at 500 mV when conducting 3 A. The component operates within a junction temperature range of -65°C to +150°C.
Feature Summary
- Guardring structure provides overvoltage protection for enhanced reliability
- Extremely fast switching characteristics enable high-frequency operation
- Low forward voltage drop minimizes conduction losses
Applications
- Primary circuits in low voltage high frequency inverters
- Freewheeling diode applications in power supplies
- DC-to-DC converter output rectification
- Polarity protection circuits
Procurement Notes
Verify the complete part number including suffixes such as /5AT or /61T against official datasheets to ensure correct packaging configuration. Confirm RoHS compliance status and specific moisture sensitivity level requirements prior to procurement. Cross-reference manufacturer documentation for any recent product change notices that may affect assembly or sourcing specifications.
Selection Notes
Select this component for designs requiring efficient rectification in compact surface-mount layouts. The DO-214AC package suits automated assembly processes. Ensure thermal management strategies account for the 150°C maximum junction temperature limit during continuous operation. Validate that the 40 V reverse voltage rating exceeds the circuit's peak inverse voltage under all operating conditions.
Part Context
This component belongs to the B340 series of Schottky barrier rectifiers from Vishay. The series offers various voltage ratings and package options tailored for different power and space constraints. The B340A variant specifically denotes the 40 V version housed in the SMA package, providing a balance between current handling capability and physical footprint for general-purpose power electronics.
Replacement Considerations
Official substitutes include B340A-E3/61T and B340A-M3/5AT. Verify pinout compatibility and thermal performance characteristics before substitution. Ensure alternative packages meet the same mechanical mounting requirements.
