RB218NS150TL

Overview

The RB218NS150TL is a silicon Schottky barrier diode manufactured by ROHM Semiconductor, designed for high-reliability applications. It features a dual anode common cathode configuration housed in a TO-263S (D2PAK) surface-mount package. The device supports an average rectified forward current of 20 A and withstands a repetitive peak reverse voltage of 150 V. Key electrical parameters include a maximum forward voltage of 0.88 V at 10 A, a surge forward current rating of 100 A, and a maximum reverse leakage current of 20 mA at 150 V. It operates within a junction temperature range up to +150 °C and meets AEC-Q101 automotive qualification standards.

Feature Summary

• Dual anode common cathode configuration for efficient power conversion circuits
• Automotive-grade reliability certified under AEC-Q101 standards
• Super low reverse leakage current characteristics for improved efficiency
• High thermal stability with a maximum operating junction temperature of +150 °C

Applications

• Switching power supplies requiring high reliability
• Automotive electronic systems
• DC-DC converter circuits

Procurement Notes

Verify the specific suffix against official documentation, as ordering codes may indicate variations in packaging or tape-and-reel specifications that do not alter the electrical function. Confirm RoHS compliance status through the manufacturer's latest specification sheet. Ensure the component matches the required TO-263S footprint for PCB layout compatibility. Cross-reference the part number with authorized distributors to confirm current production status and availability.

Selection Notes

Select this component when a dual Schottky diode with a 150 V reverse voltage rating and 20 A continuous current capacity is required. The TO-263S package offers a balance of thermal performance and surface-mount convenience. Consider the AEC-Q101 qualification if the application involves automotive environments. Evaluate the forward voltage drop of 0.88 V against system efficiency requirements compared to alternative voltage ratings within the same series.

Part Context

This part belongs to the RB218NSFH series of Schottky barrier diodes from ROHM Semiconductor. The series is characterized by its use in switching power supplies and its adherence to automotive quality standards. Similar parts in the lineup include variants with different reverse voltage ratings, such as the RB218NS100FHTL and RB218NS200FHTL, which share the same package and current capabilities but differ in blocking voltage.

Replacement Considerations

Direct substitutes within the same family include RB218NS150FH. Verify pinout compatibility and thermal resistance values before substitution.
