SP8M6TB

Overview

The SP8M6TB is a complementary power MOSFET manufactured by ROHM Semiconductor, designed for low-voltage switching applications. It integrates an N-channel and a P-channel device within a single SOP-8 package. The component supports a drain-source voltage (V_DSS) of 30V. Typical on-resistance (R_DS(on)) values are specified at various gate drive voltages, including 4V, 4.5V, and 10V. The device features a total gate charge (Q_G) suitable for efficient driving. Power dissipation (P_D) is rated at 2W under standard conditions. The unit operates within a storage temperature range of -55°C to +150°C and utilizes surface-mount technology for PCB integration.

Feature Summary

• Complementary N+P channel configuration in a compact SOP-8 package
• Low voltage operation with 30V drain-source breakdown capability
• Optimized for simplified driver circuit requirements due to integrated pair design

Applications

• DC-DC converter synchronous rectification stages
• Motor driver output stages for low-voltage systems
• Power management IC external switch implementations

Procurement Notes

Verify the specific ordering suffix (e.g., TB1) against the manufacturer's current database to confirm tape-and-reel packaging details. Confirm RoHS compliance status directly with the supplier documentation. Ensure the part number matches the exact pinout and electrical specifications required for the target circuit design before procurement.

Selection Notes

Select this component when a matched N-P pair is required for half-bridge or synchronous rectifier topologies. Evaluate the R_DS(on) values at the intended gate drive voltage to ensure conduction losses meet system efficiency targets. Consider the SOP-8 thermal performance relative to the expected continuous current load and ambient operating conditions.

Part Context

This part belongs to ROHM's series of complementary MOSFETs designed for space-constrained power applications. It serves as an alternative to discrete N-channel and P-channel MOSFETs, reducing board area and assembly complexity. The SOP-8 package provides a balance between thermal dissipation capabilities and footprint size for consumer and industrial electronics.

Replacement Considerations

Check for direct replacements such as the SP8M6HZG if availability is an issue. Verify that substitute parts maintain identical pin configurations and electrical parameters, particularly V_DSS and R_DS(on), to ensure circuit compatibility without redesign.
