BSO203PHXUMA1

Overview

The BSO203PHXUMA1 is a dual P-channel MOSFET array from Infineon’s OptiMOS™ family, housed in an 8-lead SOIC package. It supports a drain-source voltage of 20V and continuous current of 7A. Key electrical parameters include a maximum on-resistance of 21 milliohms at 4.5V gate drive and a gate charge of 39nC. The device operates within a temperature range of -55°C to 150°C and features logic-level gating for efficient control.

Feature Summary

• Dual P-channel configuration integrated into a single surface-mount package
• OptiMOS™ technology optimized for low conduction losses
• Logic-level gate compatibility for direct interface with standard drivers

Applications

• High-side switching in automotive power distribution units
• Load management in construction and agricultural vehicles
• Relay driver circuits requiring compact form factors

Procurement Notes

Verify the specific suffix XUMA1 against the manufacturer's latest documentation to confirm reel specifications and moisture sensitivity level. Ensure the design accounts for the component's thermal dissipation limits within the PG-DSO-8 package. Cross-reference the AEC-Q100 qualification status if the application requires strict automotive reliability standards.

Selection Notes

Select this component when a dual high-side switch solution is required in a small footprint. The 20V rating suits 12V nominal systems, while the 7A current capacity handles moderate loads. Consider the 21 milliohm on-resistance for efficiency calculations and verify that the logic-level gate threshold aligns with the available control signal voltages.

Part Context

This part belongs to the OptiMOS™ P series, designed for robust performance in automotive environments. It complements other high-side switches by offering a dual-channel option, reducing board space compared to discrete solutions. The integration aids in simplifying schematic designs for complex power distribution networks.

Replacement Considerations

Check for BSO203P variants with different suffixes for packaging changes. Verify pinout compatibility before substituting with other dual P-channel MOSFETs from different manufacturers.
