SP8K33FRATB

Overview

The SP8K33FRATB is a dual N-channel MOSFET manufactured by ROHM Semiconductor, designed for automotive applications with AEC-Q101 qualification. It features a SOP-8 package and operates with a drain-source voltage of 60V and a continuous drain current of 5.0A. The device exhibits a typical on-resistance of 40 mΩ at a 4.5V drive voltage. It supports surface mount installation and functions within a temperature range of -55°C to +150°C.

Feature Summary

• Dual N-channel configuration in a compact SOP-8 package
• Qualified for automotive use under AEC-Q101 standards
• Low on-resistance optimized for 4.5V drive voltages

Applications

• Automotive power switching circuits
• Load management systems requiring AEC-Q101 compliance
• Low-side switching applications in vehicle electronics

Procurement Notes

Verify the specific ordering suffix FRATB against official documentation to confirm tape and reel packaging details. Confirm supply status as the base model SP8K33FR is marked not recommended for new designs. Ensure compatibility with existing automotive design constraints before procurement.

Selection Notes

Select this component for dual-channel applications requiring 60V blocking capability and low conduction losses at 4.5V gate drive. Compare thermal performance and package dimensions against alternatives if space is constrained. Verify that the 5.0A current rating meets the specific load requirements of the target circuit design.

Part Context

This part belongs to ROHM's automotive-grade MOSFET portfolio, specifically engineered for reliability in harsh environments. The SOP-8 package provides a balance between thermal dissipation and board space efficiency. It serves as a variant of the SP8K33 series, tailored for specific manufacturing or distribution channels.

Replacement Considerations

The SP8K33HZG is listed as a similar level replacement with the same pinout and package. Verify electrical parameter equivalence and automotive qualification status when substituting.
