SP8J66FRATB

Overview

The SP8J66FRATB is a dual P-channel power MOSFET array manufactured by ROHM Semiconductor, designed for surface-mount applications. It features a drain-source breakdown voltage (VDSS) of -30V and supports a continuous drain current (ID) of ±9.0A at ambient temperature. The device exhibits a maximum on-resistance (RDS(on)) of 18.5mΩ, ensuring efficient power handling with minimal conduction losses. Packaged in an SOP-8 format, it offers a power dissipation rating of 2.0W. Key switching parameters include a typical turn-on delay time of 20ns, a rise time of 60ns, and a typical turn-off delay time of 170ns, facilitating responsive control in high-frequency circuits.

Feature Summary

• Dual P-channel configuration integrated into a single compact package
• Low on-resistance design for enhanced power efficiency
• Automotive-grade reliability through AEC-Q101 qualification
• Compliant with RoHS standards and featuring lead-free plating

Applications

• DC-DC converter circuits requiring synchronous rectification
• Motor driver interfaces for low-voltage systems
• Power management units in automotive electronics
• Load switch applications in portable devices

Procurement Notes

Verify the specific ordering suffix to ensure compliance with packaging requirements and environmental standards. Confirm that the received components match the AEC-Q101 qualification status if intended for automotive use. Check datasheet revisions for any updates to thermal characteristics or pin configurations before finalizing integration into production designs.

Selection Notes

Select this component when a dual P-channel solution is required within a limited footprint. The 18.5mΩ on-resistance makes it suitable for applications prioritizing efficiency over extreme current capacity. Ensure the operating voltage remains within the -30V limit and consider the 2.0W power dissipation capability alongside adequate PCB thermal relief strategies for reliable long-term operation.

Part Context

This part belongs to ROHM's series of dual-channel power MOSFET arrays optimized for space-constrained designs. The SOP-8 package provides a balance between thermal performance and board area efficiency. It serves as a specialized alternative to discrete dual-MOSFET setups, simplifying layout and reducing assembly complexity in multi-channel power management architectures.

Replacement Considerations

Direct substitutes must maintain the -30V/9A specification and SOP-8 footprint. Verify pinout compatibility and RDS(on) values to ensure equivalent performance. Cross-reference with other ROHM dual P-channel variants for potential drop-in replacements if supply constraints exist.
