RBQ10T45ANZC9

Overview

The RBQ10T45ANZC9 is a silicon Schottky barrier diode manufactured by ROHM Semiconductor, designed for general rectification applications. It features a dual anode common cathode configuration housed in a TO-220FN (3-pin) leaded package. The device supports a maximum repetitive reverse voltage of 45 V and an average rectified forward current of 10 A. Key electrical characteristics include a maximum forward voltage of 0.65 V at 5 A, a maximum reverse current of 0.15 mA at 45 V, and a maximum junction temperature of 150 °C. It complies with the AEC-Q101 automotive grade standard.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q101 standards
• Low reverse leakage current design for enhanced efficiency
• Dual anode common cathode topology for flexible circuit integration

Applications

• General-purpose rectification in automotive electronic systems
• DC power supply output stages
• Freewheeling diodes in motor control circuits

Procurement Notes

Verify the complete part number RBQ10T45ANZC9 against official ROHM documentation to confirm the specific tube packaging and suffix designation. Ensure compatibility with existing thermal management designs due to the TO-220FN package constraints. Confirm that the component status aligns with project requirements, as this variant may be designated for supporting existing customers rather than new designs.

Selection Notes

Select this component when a robust, leaded Schottky diode with high current capacity is required for automotive or industrial environments. The TO-220FN package offers superior heat dissipation compared to surface-mount alternatives. Consider the 45 V rating and 10 A continuous current capability to ensure adequate headroom for load variations. Verify that the common cathode configuration matches the schematic requirements for the intended application.

Part Context

This component belongs to the RBQ series of Schottky barrier diodes from ROHM Semiconductor, specifically engineered for high-reliability applications. The series emphasizes low reverse current and high thermal stability, making it suitable for demanding environments. The RBQ10T45ANZC9 variant utilizes a through-hole mounting style, distinguishing it from the SMD variants within the same product family.
