RB088T-30NZC9

Overview

The RB088T-30NZC9 is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for high-reliability applications including automotive electronics. It features a cathode-common dual configuration within a TO-220FN (3PIN) leaded package. Key electrical specifications include a reverse voltage of 30V, an average rectified forward current of 30A, and a maximum forward voltage of 0.72V at 15A. The device supports a peak forward surge current of 50A and operates with a junction temperature up to 150°C.

Feature Summary

• Cathode common dual type configuration
• High reliability construction
• Super low reverse leakage current

Applications

• Automotive power supply circuits
• General-purpose rectification in industrial equipment
• DC-DC converter output stages

Procurement Notes

Verify the complete part number RB088T-30NZC9 against official ROHM documentation to ensure correct suffix identification. Confirm that the component status aligns with project requirements, as this specific variant may be designated for existing customers rather than new designs. Cross-reference the TO-220FN package dimensions and thermal characteristics with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a dual Schottky diode with a 30A continuous current rating is required in a through-hole package. The cathode-common topology simplifies circuit design for synchronous rectification or freewheeling applications. Ensure the system can accommodate the 150°C maximum junction temperature and verify that the super low reverse leakage current meets the efficiency standards of the target application environment.

Part Context

This device belongs to ROHM's RB088 series of Schottky barrier diodes, which are engineered for robust performance in demanding environments. The series emphasizes high reliability and low forward voltage drop to minimize power loss. The TO-220FN package provides efficient heat dissipation capabilities suitable for medium-to-high current applications, distinguishing it from surface-mount alternatives in the same family.

Replacement Considerations

Check for direct pin-compatible substitutes such as the RB088T-60NZC9 if higher voltage ratings are acceptable. Verify that any replacement maintains the cathode-common dual configuration and similar thermal resistance characteristics to ensure seamless integration without redesigning the heatsinking infrastructure.
