Overview
The SP8M21FRATB is a complementary MOSFET pair manufactured by ROHM Semiconductor, designed for automotive applications with AEC-Q101 qualification. It integrates an N-channel and a P-channel enhancement-mode transistor in a single SOP-8 package. The N-channel device features a drain-source voltage of 30V and a typical on-resistance of 0.017Ω at 4.5V gate drive. The P-channel counterpart offers a 30V breakdown voltage and a typical on-resistance of 0.022Ω under the same conditions. This configuration supports low-voltage driving requirements while maintaining high current capabilities suitable for power management circuits.
Feature Summary
- Integrated complementary N-channel and P-channel MOSFETs in a compact SOP-8 package
- Qualified for automotive environments under AEC-Q101 standards
- Optimized for low-voltage gate drive operation at 4V and 4.5V
- Designed to minimize switching losses through optimized gate charge characteristics
Applications
- Automotive power management systems
- Low-side and high-side switching circuits
- DC-DC converter output stages
- Motor driver interfaces
Procurement Notes
Verify the specific ordering suffix FRATB to ensure correct tape-and-reel packaging and quantity. Confirm that the AEC-Q101 qualification status meets your project's reliability requirements. Check for any end-of-life notices or last-time-buy recommendations from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a matched complementary pair is required for synchronous rectification or bridge configurations. Ensure the 30V voltage rating aligns with the system's maximum operating voltage. Verify that the 4V/4.5V drive voltage compatibility matches the available control logic levels in the design.
Part Context
This part belongs to ROHM's series of 4V-drive complementary MOSFETs. It is specifically engineered to replace older discrete solutions by providing better thermal performance and reduced board space. The SOP-8 package allows for efficient heat dissipation compared to smaller surface-mount options.
Replacement Considerations
Consult ROHM documentation for direct pin-compatible replacements if this part becomes obsolete. Ensure any substitute maintains the same AEC-Q101 qualification and complementary structure.
