SP8K1TB

Overview

The SP8K1TB is a dual N-channel power MOSFET manufactured by ROHM Semiconductor, designed for general-purpose switching applications. It features a 30V drain-source voltage rating and a continuous drain current of 5.0A. The device incorporates a built-in gate-source protection diode to enhance reliability against electrostatic discharge. Packaged in an 8-pin SOP format, it offers low on-resistance characteristics suitable for compact surface-mount designs. Key electrical parameters include a typical Rds(on) optimized for efficient power handling in DC/DC converters and power switching circuits.

Feature Summary

• Dual N-channel configuration within a single package
• Integrated gate-source protection diode
• Low on-resistance for efficient switching
• Compact surface-mount SOP8 packaging

Applications

• Power switching circuits
• DC/DC converter modules
• General-purpose electronic equipment

Procurement Notes

Verify the specific ordering suffix to confirm tape-and-reel packaging quantities and RoHS compliance status. Ensure the component matches the required SOP8 footprint dimensions and pinout configuration for your PCB layout. Cross-reference the manufacturer's latest datasheet for any potential product change notices or end-of-life announcements before finalizing procurement plans.

Selection Notes

Select this component when a dual N-channel MOSFET with 30V capability and 5A current handling is required in a small form factor. Consider the thermal performance of the SOP8 package relative to your application's power dissipation needs. Verify that the drive voltage requirements align with the specified Rds(on) conditions for optimal efficiency in your target circuit design.

Part Context

The SP8K1TB belongs to ROHM's series of silicon N-channel MOSFETs intended for middle-power applications. It shares functional similarities with other devices in the SP8K family but is distinguished by its specific voltage and current ratings. This part is commonly used in consumer electronics and industrial control systems where space constraints and switching efficiency are critical design factors.

Replacement Considerations

Direct substitutes include the SP8K1 and SP8K1FU6TB from ROHM, which share identical electrical specifications and pinouts. Alternative manufacturers may offer compatible dual N-channel MOSFETs with matching 30V/5A ratings, provided the package dimensions and thermal characteristics are verified for compatibility.
