Overview
The RBQ20T45ANZC9 is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for automotive applications in compliance with the AEC-Q101 standard. 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 45V and an average rectified forward current of 20A. Key electrical parameters include a maximum forward voltage of 0.65V at 10A and a maximum reverse current of 0.3mA at 45V. It withstands a forward surge current of 100A and operates within a junction temperature range up to 150°C.
Feature Summary
- Automotive-grade reliability certified under the AEC-Q101 standard
- Low reverse leakage current design for enhanced efficiency
- Dual anode common cathode topology for flexible circuit integration
Applications
- Automotive power supply circuits
- DC-DC converter freewheeling paths

Procurement Notes
Verify the specific suffix C9 against official documentation to confirm package and tape/reel specifications. Confirm RoHS compliance status as required by your manufacturing standards. Ensure the component meets the AEC-Q101 qualification requirements for your target application environment. Cross-reference the part number with the manufacturer's latest datasheet to validate availability and design recommendations.
Selection Notes
Select this component when a robust, automotive-certified Schottky diode is required for low-voltage, high-current applications. The TO-220FN package facilitates through-hole mounting and effective heat dissipation. Consider the 45V rating and 20A continuous current capacity to ensure adequate headroom for your system's operational peaks and thermal conditions.
Part Context
This part belongs to the RBQ series of Schottky barrier diodes from ROHM Semiconductor, specifically engineered for automotive use. The series emphasizes low reverse current and high reliability. The RBQ20T45ANZC9 variant utilizes a leaded TO-220FN package, distinguishing it from surface-mount counterparts like the NS series. It serves as a specialized solution for automotive-grade power management requiring proven durability.
Replacement Considerations
Consult official substitution guides for equivalent automotive-grade Schottky diodes with matching voltage and current ratings. Verify pinout compatibility and thermal characteristics before replacing. Generic industrial diodes may not meet the AEC-Q101 reliability standards required for this application.
