RB088NS150FHTL

Overview

The RB088NS150FHTL is a silicon Schottky barrier diode manufactured by ROHM Semiconductor, housed in a TO-263S (D2PAK) surface-mount package. It features a dual anode common cathode configuration with a maximum repetitive reverse voltage of 150 V and an average rectified forward current rating of 10 A. The device exhibits a maximum forward voltage of 780 mV at 5 A and a maximum reverse current of 15 uA at 150 V. It supports a forward surge current of 50 A and operates within a junction temperature range up to +150 °C. This component holds AEC-Q101 qualification for automotive reliability standards.

Feature Summary

• Utilizes a blocking metal structure to suppress reverse leakage current degradation at elevated temperatures, mitigating thermal runaway risks in high-temperature environments.
• Features ultra-low reverse leakage current characteristics compared to general fast recovery diodes, contributing to reduced power consumption and improved efficiency in switching applications.
• Incorporates a dual anode common cathode configuration within a compact surface-mount package, facilitating efficient circuit layout and heat dissipation.

Applications

• Automotive electronic systems requiring AEC-Q101 qualified components
• Switching power supply circuits demanding low forward voltage drop
• High-temperature industrial equipment power management

Procurement Notes

Verify the specific ordering suffix against official ROHM documentation to confirm packaging type and reel specifications. Ensure the procurement channel sources genuine components with traceable manufacturing data. Confirm that the delivered parts match the exact part number including all alphanumeric characters to avoid functional mismatches due to minor variant differences.

Selection Notes

Select this component when designing circuits that require robust performance under high-temperature conditions where standard Schottky diodes might suffer from excessive leakage current. The dual anode common cathode arrangement allows for bridge rectifier or freewheeling configurations without additional discrete components. Consider the TO-263S package dimensions for PCB footprint compatibility and thermal management requirements relative to the 10 A current rating.

Part Context

This device belongs to the RBxx8 series of Schottky barrier diodes designed specifically for automotive and industrial applications. The series addresses the inherent limitation of traditional Schottky diodes regarding reverse leakage current increase at high temperatures. By employing specialized blocking metal technology, the RBxx8 series maintains stable electrical characteristics, ensuring reliable operation in demanding thermal environments typical of modern vehicle electronics and power conversion systems.
