SS29LHR3G

Single Diodes Overview

The SS29LHR3G is a Schottky barrier rectifier manufactured by Taiwan Semiconductor Corporation. It features a single diode configuration in a Sub SMA-2 (DO-219AB) surface-mount package. The device supports an average forward current of 2 A and a repetitive peak reverse voltage of 90 V. Key electrical parameters include a maximum forward voltage of 850 mV at 2 A, a surge forward current capability of 50 A, and a maximum reverse leakage current of 100 µA. It operates within a junction temperature range of -55°C to +150°C and holds AEC-Q101 automotive qualification.

Single Diodes Feature Summary

• Automotive-grade reliability certified under the AEC-Q101 standard for robust performance in demanding environments.
• Low forward voltage drop characteristic designed to minimize power loss and enhance overall system efficiency.
• Ultra-fast switching speed enabled by the Schottky barrier technology to reduce recovery losses.

Single Diodes Applications

• DC-DC converter circuits requiring high-efficiency rectification.
• Free-wheeling diodes in inductive load switching applications.
• Polarity protection circuits in automotive electronic modules.

Single Diodes Procurement Notes

Verify the specific suffix 'G' against the manufacturer's official documentation to confirm RoHS compliance status and lead time requirements. Confirm that the Sub SMA-2 package dimensions match the target PCB footprint. Ensure the selected component meets the required AEC-Q101 qualification level if used in automotive designs. Cross-reference the datasheet revision date to ensure parameter accuracy.

Single Diodes Selection Notes

Select this component when a 2 A current rating and 90 V blocking voltage are required in a compact surface-mount form factor. The Sub SMA-2 package offers a smaller footprint compared to standard SMA packages while maintaining similar thermal characteristics. Consider the 150°C maximum junction temperature for high-temperature operation scenarios. Verify that the 850 mV forward voltage aligns with the system's power budget constraints.

Single Diodes Part Context

This part belongs to the SS2xx series of Schottky barrier rectifiers from Taiwan Semiconductor. The series is characterized by low forward voltage and high surge current capability. The 'LHR' designation typically indicates a specific packaging variant or material composition optimized for surface-mount assembly. The 'G' suffix generally denotes environmental compliance, such as being halogen-free or RoHS compliant, subject to official verification.

Single Diodes Replacement Considerations

Direct replacements must match the 2 A current rating, 90 V reverse voltage, and Sub SMA-2 package. Verify pinout compatibility and thermal resistance values. Check for equivalent AEC-Q101 qualification if automotive use is intended. Consult the manufacturer's substitution guide for validated alternatives.
