SP8M51TB1

Overview

The SP8M51TB1 is a complementary power MOSFET manufactured by ROHM Semiconductor, featuring one N-channel and one P-channel transistor in an SOP-8 surface-mount package. It supports a drain-source voltage (Vds) of 100 V with continuous drain currents of 3 A for both channels. The device exhibits low on-resistance values of 0.135 Ω at Vgs = 4 V and 0.12 Ω at Vgs = 10 V. Key electrical parameters include a total gate charge (Qg) of 8.5 nC, a maximum power dissipation (Pd) of 2 W, and a drive voltage rating of 4 V. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Complementary N-channel and P-channel configuration within a single compact package
• Low on-resistance optimized for efficient switching performance
• Surface-mount SOP-8 footprint suitable for space-constrained designs

Applications

• Switching applications in power supplies
• DC/DC converter circuits
• Motor driver interfaces

Procurement Notes

Verify the specific suffix TB1 against the manufacturer's current datasheet to confirm packaging details such as tape-and-reel specifications. Ensure compatibility with standard SOP-8 footprints during PCB layout. Cross-reference RoHS compliance status directly with official documentation before finalizing procurement plans.

Selection Notes

Select this component when a dual-channel solution is required for 100 V applications with moderate current demands around 3 A. The low gate charge facilitates faster switching speeds compared to higher-capacitance alternatives. Consider the 2 W power dissipation limit and thermal management requirements for the SOP-8 package in high-duty-cycle scenarios.

Part Context

This part belongs to ROHM's complementary MOSFET lineup designed for general-purpose switching. It serves as an alternative to discrete N and P-channel pairs, reducing board space and assembly complexity. The SOP-8 package provides a balance between thermal performance and miniaturization for consumer and industrial electronics.

Replacement Considerations

Evaluate HP8M51TB1 or similar ROHM complementary MOSFETs with matching 100 V ratings and comparable Rds(on) characteristics. Verify pinout compatibility and thermal resistance values before substitution to ensure circuit integrity.
