RB238T-30HZC9

Overview

The RB238T-30HZC9 is a cathode common dual Schottky barrier diode designed for automotive applications, complying with the AEC-Q101 standard. It features a TO-220FN (3PIN) leaded package with dimensions of 15.0x10.0 mm and a thickness of 4.8 mm. Key electrical specifications include a maximum repetitive reverse voltage of 35V and a continuous forward current rating of 40A. The device exhibits a maximum forward voltage of 0.75V at 20A and a maximum reverse leakage current of 0.012mA at 30V. It supports a junction temperature up to 150°C and operates within a storage temperature range of -55°C to 150°C.

Feature Summary

• Cathode common dual configuration for efficient circuit design
• High reliability construction suitable for automotive environments
• Super low reverse leakage current characteristics

Applications

• Automotive power supply circuits
• Switching power supplies requiring AEC-Q101 compliance
• General rectification in high-current automotive systems

Procurement Notes

Verify that the specific suffix C9 matches the required packaging format, as this variant is designated for existing customers only and is not recommended for new designs. Confirm RoHS compliance status and ensure the TO-220FN package fits the thermal and mechanical constraints of the target assembly before finalizing procurement plans.

Selection Notes

Select this component when an automotive-grade Schottky diode with a cathode common dual structure is required. Ensure the 30V reverse voltage rating aligns with the system's peak inverse voltage requirements. Consider the 40A current capacity and the thermal management capabilities of the TO-220FN package for the intended application load.

Part Context

This part belongs to the RB238T series of Schottky barrier diodes manufactured by Rohm Semiconductor. The series is characterized by its high reliability and low forward voltage drop, making it suitable for demanding power conversion applications. The HZ suffix typically indicates AEC-Q101 qualification, distinguishing it from non-automotive variants within the same family.

Replacement Considerations

Check for direct substitutes within the RB238T series that may have different voltage ratings or package options. Verify compatibility with any alternative parts regarding pinout configuration, thermal resistance, and maximum current ratings to ensure seamless integration without redesigning the PCB layout.
