BSO303PHXUMA1

Overview

The BSO303PHXUMA1 is an OptiMOS-P small-signal transistor featuring a dual P-channel configuration in a PG-DSO-8 package. It operates with a drain-source voltage of -30 V and continuous drain current up to -8.2 A at 25 °C. The device exhibits a maximum on-state resistance of 21 mΩ at VGS=-4.5V. It supports logic level switching, handles pulsed currents of -32.8 A, and functions within a temperature range of -55 °C to 150 °C.

Feature Summary

• Dual P-channel enhancement mode architecture integrated into a single surface-mount package
• Logic level gate drive capability for direct interface with standard digital control circuits
• Robust thermal performance supporting operation up to 150 °C junction temperature
• Integrated reverse diode with defined forward characteristics and recovery parameters

Applications

• Low-side switching in automotive power distribution modules
• Motor control bridge configurations requiring complementary channel pairs
• Industrial load switching applications with high surge current demands

Procurement Notes

Verify the specific ordering suffix XUMA1 corresponds to the required tape-and-reel packaging format before finalizing procurement orders. Confirm that the component meets RoHS compliance standards and halogen-free requirements as specified by IEC61249-2-21 for your manufacturing environment. Ensure the PG-DSO-8 footprint matches your PCB design guidelines.

Selection Notes

Select this component when a compact dual P-channel solution is required for low-voltage switching tasks. The 21 mΩ on-resistance at -4.5 V gate drive makes it suitable for logic-level interfacing without additional level shifters. Consider the -30 V rating and -8.2 A continuous current capacity against your peak load requirements and thermal dissipation constraints.

Part Context

This part belongs to Infineon's OptiMOS-P family of small-signal transistors. These devices are engineered for high efficiency and reliability in automotive and industrial markets. The BSO303P specifically provides a matched pair of P-channel MOSFETs, simplifying circuit design for half-bridge or synchronous rectification topologies compared to using discrete single-channel components.
