SP8K24FRATB

Overview

The SP8K24FRATB is a P-channel MOSFET manufactured by ROHM Semiconductor, designed for surface-mount applications in SOP-8 packages. It features a drain-source breakdown voltage (Vds) of 45 V and supports a continuous drain current (Id) of up to 6 A. The device exhibits a typical on-resistance (Rds(on)) of 36 mΩ at a gate-source voltage of -10 V, with a maximum gate-source voltage rating of ±20 V. Key switching parameters include a total gate charge (Qg) of 23 nC, a turn-on delay time of 10 ns, and rise/fall times of 28 ns. It operates within a temperature range of -55°C to +150°C junction temperature and has a power dissipation rating of 2 W.

Procurement Notes

Verify the specific ordering suffix 'TB' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Confirm that the component status remains acceptable for your production timeline, as availability may vary based on manufacturing lifecycle stages. Ensure all electrical parameters match your circuit requirements before finalizing procurement orders.

Selection Notes

Select this component when a 45 V P-channel MOSFET with low Rds(on) and automotive qualification is required. Compare the 6 A current rating and 2 W power dissipation against your thermal management capabilities. Consider the SOP-8 package dimensions for board space constraints. Verify compatibility with your drive voltage levels, specifically ensuring the -10 V gate drive aligns with the specified Rds(on) performance characteristics.

Part Context

This part belongs to ROHM's lineup of automotive-grade power MOSFETs. It shares similar electrical characteristics with other 45 V P-channel devices in the series but is distinguished by its specific packaging and automotive certification. It serves as a solution for applications requiring robust switching performance in automotive and industrial environments.

Replacement Considerations

Check for direct pin-compatible alternatives such as the SP8M24FRATB if sourcing issues arise, though verify differences in current ratings and on-resistance. Ensure any substitute maintains AEC-Q101 qualification if automotive use is intended. Cross-reference package dimensions and thermal characteristics to ensure mechanical fit.
