RB088BM100TL

Overview

The RB088BM100TL is a silicon Schottky barrier diode manufactured by ROHM Semiconductor, housed in a TO-252-3 (DPAK) surface-mount package. It features a dual anode common cathode configuration with a maximum repetitive reverse voltage of 100 V and an average forward current rating of 10 A per diode. The device exhibits a maximum forward voltage of 870 mV at 5 A and a maximum reverse leakage current of 5 µA at 100 V. It supports a non-repetitive peak forward surge current of 100 A and operates at junction temperatures up to +150 °C. This component holds AEC-Q101 automotive qualification.

Feature Summary

• Dual anode common cathode configuration for efficient power management
• Automotive-grade reliability certified under AEC-Q101 standards
• Super low reverse leakage current characteristics
• High thermal stability with a maximum junction temperature of 150 °C

Applications

• Switching power supplies
• DC-DC converters
• Automotive electronic systems

Procurement Notes

Verify the specific ordering suffix TL against the required tape-and-reel quantity of 2500 units. Confirm that the TO-252-3 package dimensions match the target PCB footprint. Ensure the design accounts for the 10 A continuous current rating and the 100 V reverse voltage limit under all operating conditions. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a dual-diode arrangement is required within a single compact SMD package. The TO-252-3 form factor provides robust thermal dissipation capabilities suitable for high-current applications. The AEC-Q101 certification makes it appropriate for automotive environments where long-term reliability is critical. Compare the 870 mV forward voltage drop against system efficiency requirements.

Part Context

This part belongs to the RB088 series of super low IR Schottky barrier diodes designed for switching power supply applications. The series includes various voltage ratings and package options, such as the RB088BM200TL and RB088NS100TL. The RB088BM100TL specifically targets 100 V applications requiring automotive-grade durability and low conduction losses in a DPAK-style housing.

Replacement Considerations

The RB088BM100FHTL is listed as a similar level replacement with the same pinout and package. Verify that the FHTL suffix does not alter the electrical parameters or packaging specifications before substitution.
