RB218T-40NZC9

Overview

The RB218T-40NZC9 is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for high-reliability applications. It features a dual common cathode configuration housed in a TO-220FN (3-pin) leaded package. The device supports an average rectified forward current of 20 A and a repetitive reverse voltage of 40 V. Key electrical parameters include a maximum forward voltage of 0.77 V at 10 A and a maximum reverse current of 5 mA at 40 V. The component operates within a junction temperature range up to 150°C and is compliant with RoHS standards.

Feature Summary

• Dual common cathode configuration for efficient circuit design
• Super low reverse leakage current for improved efficiency
• High reliability construction suitable for demanding environments

Applications

• Power supply circuits requiring high reliability
• Automotive electronics systems
• General purpose rectification in industrial equipment

Procurement Notes

Verify the specific suffix 'NZ' against official ROHM documentation to confirm exact manufacturing lot or variant details, as suffixes can indicate specific packaging or quality certifications. Confirm that the component status remains appropriate for your project lifecycle, as some variants may be designated for existing customers only. Ensure the TO-220FN package dimensions match your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a dual common cathode Schottky diode is required with a 40 V rating and 20 A current capacity. The TO-220FN package provides robust thermal performance for through-hole mounting. Consider the super low reverse current feature if minimizing leakage in high-temperature environments is critical. Verify that the 0.77 V forward voltage drop meets the efficiency targets of the target power stage.

Part Context

This part belongs to the RB218T series of Schottky barrier diodes from ROHM Semiconductor. The series is characterized by high reliability and low reverse current, making it suitable for automotive and industrial applications. The TO-220FN package offers a balance of thermal dissipation and mechanical stability for through-hole assembly.

Replacement Considerations

The RB218T-40HZC9 is a similar variant within the same series, also featuring a dual common cathode configuration and 40 V rating. Both parts share the TO-220FN package and similar electrical characteristics. Verify specific parameter tolerances and availability status before substitution.
