RB098BM-30TL

Overview

The RB098BM-30TL is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for surface mount applications in the TO-252AA (D-Pak) package. It features a common cathode configuration with three terminals. Key electrical specifications include a maximum repetitive reverse voltage of 35 V and a standard reverse voltage rating of 30 V. The device supports an average rectified forward current of 6 A and a surge forward current of 50 A. Forward voltage is limited to 0.72 V at 3 A, while reverse current remains below 1.5 mA at 30 V. The junction temperature reaches 175 °C, with a storage range from -55 °C to 175 °C.

Feature Summary

• Ultra-low reverse leakage current characteristics suitable for high-efficiency power conversion
• Automotive-grade reliability certified under AEC-Q101 standards
• Surface-mount construction in a compact D-Pak package for automated assembly

Applications

• Switching power supply circuits
• Automotive electronic systems requiring high reliability
• General-purpose rectification in low-voltage DC-DC converters

Procurement Notes

Verify the specific suffix TL indicates tape-and-reel packaging containing 2500 units per reel. Confirm RoHS compliance status matches current regulatory requirements. Ensure the component meets automotive qualification standards if deployed in vehicle electronics. Cross-reference the datasheet revision date to confirm technical parameters have not changed. Validate that the ordering part number aligns with the required package code JEITA SC-63.

Selection Notes

Select this component when low reverse leakage is critical for standby power efficiency. The 30 V rating suits low-voltage output stages where standard silicon diodes exhibit higher losses. The 175 °C junction capability allows operation in thermally constrained environments without derating. Consider the TO-252AA footprint for PCB layout compatibility with existing D-Pak designs. Evaluate thermal resistance requirements against the expected average forward current load.

Part Context

This part belongs to the RB098 series of ultra-low IR Schottky barrier diodes. It shares the same pinout and package dimensions as related variants like the RB098BM-30FHH but differs in automotive qualification and thermal ratings. The series targets applications demanding improved efficiency over standard rectifiers. Competing parts in this segment typically offer similar voltage ratings but may lack the specific automotive certification or leakage performance metrics defined here.

Replacement Considerations

The RB098BM-30FHH serves as a direct substitute with identical pinout and package. Both share the 30 V reverse voltage and 6 A forward current ratings. Verify thermal management requirements, as the FHH variant supports a higher junction temperature of 175 °C compared to standard industrial grades. Ensure the replacement maintains the required AEC-Q101 qualification if used in automotive contexts.
