PBSS5240X-QX is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Nexperia USA Inc.. Its product description is PBSS5240X-Q/SOT89/MPT3. Review the specifications below when checking this part for your BOM.
The PBSS5240X-QX is a PNP bipolar junction transistor (BJT) manufactured by Nexperia USA Inc. It is housed in an SOT-89 surface-mount package and operates with a maximum collector current of 2 A. The device features a collector-emitter breakdown voltage (VCEO) of 40 V and a collector-base voltage (VCBO) of 40 V, with an emitter-base voltage (VEBO) rating of 5 V. Key electrical parameters include a DC current gain (hFE) minimum of 300 and a transition frequency (fT) of 150 MHz. Power dissipation is rated at 1.35 W, and the unit supports an operating temperature range from -65 °C to +150 °C.
Verify the specific suffix 'QX' against official Nexperia documentation to confirm it denotes the AEC-Q101 qualified automotive grade variant. Ensure the ordering part number matches the exact tape and reel specifications required for your assembly line. Cross-reference the datasheet revision date to guarantee compliance with current RoHS and REACH directives before finalizing procurement orders.
Select this component when a high-current PNP switch is required in space-constrained designs. The SOT-89 package offers superior thermal performance compared to smaller alternatives like SOT-23. Consider the low saturation voltage to minimize power loss in battery-operated applications. Verify that the 40 V voltage rating aligns with the system's maximum supply rails.
This component belongs to the PBSS5240 series of low VCesat PNP transistors designed for general-purpose switching. The series includes variants with different packaging and qualification levels. The PBSS5240X-QX specifically targets automotive and high-reliability consumer electronics markets requiring robust performance under varying thermal conditions.
