RB088T100NZC9

Overview

The RB088T100NZC9 is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for automotive applications under the AEC-Q101 standard. It features a dual anode common cathode configuration housed in a TO-220FN (3-pin) leaded package. Key electrical specifications include a maximum repetitive reverse voltage of 100V and an average rectified forward current of 10A. The device exhibits a maximum forward voltage of 0.87V at 5A and a maximum reverse current of 0.15mA at 100V. It supports a junction temperature up to 150°C and operates within a storage temperature range of -40°C to 150°C.

Feature Summary

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

Applications

• Automotive power supply circuits
• DC-DC converter output rectification
• Freewheeling diodes in motor control systems

Procurement Notes

Verify the complete part number including the suffix C9 against official ROHM documentation to ensure correct packaging and specification alignment. Confirm that the component status aligns with project requirements, as certain variants may be designated for existing customers only. Cross-reference the AEC-Q101 qualification data directly from the manufacturer's datasheet to validate automotive suitability before procurement.

Selection Notes

Select this component when a robust, leaded Schottky diode with high current handling is required for automotive environments. The dual anode configuration offers flexibility in bridge or synchronous rectifier topologies. Ensure the PCB layout accommodates the TO-220FN package dimensions and provides adequate thermal dissipation for the 10A continuous current rating. Verify that the 100V reverse voltage rating exceeds the peak inverse voltage in the target application circuit.

Part Context

This component belongs to the RB088 series of Schottky barrier diodes, which are specifically engineered for high-reliability automotive electronics. The series emphasizes low forward voltage drop and minimal reverse leakage to enhance system efficiency. The TO-220FN package variant provides a balance between high current capacity and ease of mounting on heatsinks, distinguishing it from surface-mount alternatives in the same family.

Replacement Considerations

Direct substitutes within the RB088 series include RB088T-60HZC9 and RB088T150HZC9, differing primarily in reverse voltage ratings. For equivalent performance in a TO-220FN package, verify compatibility with other automotive-grade Schottky diodes offering similar 10A current and low IR specifications.
