BB914E6327HTSA1

Overview

The BB914E6327HTSA1 is a small-signal switching diode manufactured by Infineon Technologies. It features a single diode configuration housed in a surface-mount SOT-23 (SC-59) package with three pins. The device supports a maximum repetitive reverse voltage of 100 V and an average forward rectified current of 250 mA. Key electrical parameters include a peak forward surge current of 4.5 A, a typical reverse recovery time of 4 ns, and a maximum forward voltage drop of 1.25 V at 150 mA. The component operates within a junction temperature range of -65°C to +150°C and is qualified under the AEC-Q100 automotive standard.

Feature Summary

• High-speed switching capability with a short reverse recovery time for efficient signal processing.
• Automotive-grade reliability compliant with AEC-Q100 standards for harsh environment operation.
• Compact surface-mount packaging suitable for space-constrained printed circuit board designs.

Applications

• General-purpose signal switching in electronic circuits.
• Clamping and protection applications in automotive electronics systems.
• High-frequency rectification tasks requiring fast response times.

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm tape-and-reel quantities and packaging specifications. Ensure that the AEC-Q100 qualification status aligns with project requirements before finalizing procurement orders. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability.

Selection Notes

Select this component when a robust, high-speed silicon switching diode is required for automotive or industrial applications. The 100 V reverse voltage rating provides adequate headroom for low-voltage signal lines. Consider the SOT-23 footprint compatibility during layout design to ensure proper thermal dissipation and mechanical stability within the assembly process.

Part Context

This part belongs to the SMBD914 series of small-signal switching diodes produced by Infineon Technologies. The E6327HTSA1 suffix indicates specific manufacturing and packaging details consistent with Infineon's standard product coding system. It serves as a reliable alternative for general-purpose switching roles where speed and automotive durability are prioritized over power handling capacity.

Replacement Considerations

Direct substitutes include other AEC-Q100 qualified small-signal diodes in SOT-23 packages with similar 100 V ratings and fast recovery characteristics. Verify pinout compatibility and thermal performance metrics before implementing any cross-brand replacements in existing designs.
