• Automotive-grade reliability certified under the AEC-Q101 standard, ensuring suitability for demanding vehicle electronic environments.
• Enhancement-mode operation optimized for low-voltage switching applications with fast transition speeds.

Applications

• Low-side load switching circuits
• General-purpose signal switching in automotive electronics
• Battery protection modules

Procurement Notes

Verify the specific suffix HE3-TP against the manufacturer's official datasheet to confirm the exact tape-and-reel quantity and packaging variant. Ensure the component meets the required AEC-Q101 qualification level for your target application. Cross-reference the pinout diagram in the official documentation to prevent orientation errors during assembly. Confirm RoHS compliance status through the manufacturer's latest certification documents before finalizing procurement orders.

Selection Notes

Select this component when a dual N-channel solution is required in a minimal footprint. The 50V rating provides adequate headroom for 12V or 24V automotive systems. Consider the 1.6 Ohm on-resistance for power loss calculations in continuous conduction modes. The AEC-Q101 certification makes it appropriate for automotive sectors where standard commercial parts are insufficient. Evaluate thermal management requirements based on the 320 mW power dissipation limit.

Part Context

This part belongs to the BSS138AKDW series from Micro Commercial Components. It represents an automotive-grade variant of the standard BSS138 small-signal MOSFET family. The dual configuration distinguishes it from single-channel counterparts like the BSS138WT106. The HE3-TP suffix indicates specific manufacturing and packaging attributes defined by MCC.

Replacement Considerations

Direct substitutes include other dual N-channel MOSFETs in SOT-363 packages such as the BSS138AKDWS-TP from the same manufacturer. Verify electrical parameters match the 50V Vds and 220mA Id ratings. Check if alternative parts hold equivalent AEC-Q101 automotive qualifications for direct replacement in validated designs.
