SP8J5FRATB

Overview

The SP8J5FRATB is a dual P-channel power MOSFET manufactured by ROHM Semiconductor, housed in an SOP-8 surface-mount package. It features a drain-source voltage of -30 V and a continuous drain current of -7 A. The device exhibits a typical on-resistance of 0.03 Ω at a gate-source voltage of 4 V, with reduced values of 0.025 Ω at 4.5 V and 0.02 Ω at 10 V. Total gate charge is typically 25 nC, supporting fast switching capabilities. Power dissipation is rated at 2 W, with an operating temperature range from -55°C to +150°C. The component is qualified under the AEC-Q101 automotive standard.

Feature Summary

• Dual P-channel configuration integrated into a single compact SOP-8 package for space-efficient circuit design.
• Optimized for 4 V drive voltages, enabling simplified driver circuit requirements compared to traditional logic-level devices.
• AEC-Q101 qualification ensures reliability and performance consistency suitable for demanding automotive electronic applications.

Applications

• Automotive load switching circuits requiring high reliability and low on-resistance.
• Power management modules utilizing 4 V logic-compatible control signals.
• Motor driver interfaces where dual complementary or independent P-channel control is necessary.

Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel packaging format, as indicated by the ATB designation. Confirm that the AEC-Q101 qualification aligns with your target automotive application's thermal and electrical stress requirements. Ensure the SOP-8 footprint matches your PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component when a dual P-channel solution is required within a small SOP-8 footprint. The 4 V drive characteristic makes it suitable for systems where the control logic operates at lower voltages than standard 10 V gate thresholds. Consider the 2 W power dissipation limit and thermal resistance of the SOP-8 package when designing heat management strategies for high-current loads.

Part Context

This part belongs to ROHM's series of automotive-grade power MOSFETs designed for robust performance in vehicle electronics. The SOP-8 package provides a balance between current handling capability and board space efficiency. As a dual device, it simplifies bill-of-materials and assembly processes for applications requiring multiple P-channel switches.

Replacement Considerations

The SP8M10FRA is listed as a similar level replacement with the same pinout and package, though it offers different electrical characteristics including higher current capacity and lower on-resistance at specific drive voltages. Verify compatibility with existing thermal and electrical designs before substitution.
