PBLS2003S,115

Overview

The PBLS2003S is a PNP low VCEsat Breakthrough In Small Signal (BISS) transistor and an NPN Resistor-Equipped Transistor (RET) integrated in a single SOT96-1 (SO8) surface-mount package. The PNP section provides a collector-emitter voltage of -20 V, a continuous collector current of -3 A, and a saturation resistance of 75 mΩ at -2 A. The NPN section features a collector-emitter voltage of 50 V, an output current of 100 mA, and an internal bias resistor of 10 kΩ. This dual-component configuration enables space-saving designs for load switching applications.

Feature Summary

• Combines a low saturation voltage BISS transistor with a resistor-equipped transistor in one compact package to reduce component count.
• Offers a low threshold voltage compared to MOSFETs, requiring minimal drive power for operation.
• Provides a space-saving solution suitable for portable equipment and high-side switching applications.

Applications

• Supply line switches
• Battery charger switches
• High-side switches for LEDs, drivers, and backlights
• Portable equipment

Procurement Notes

Verify the manufacturer status as Nexperia handles former NXP Standard Product business. Confirm the specific ordering suffix matches the required packing method, such as tape and reel quantities. Ensure the data sheet revision aligns with current production specifications before finalizing procurement orders.

Selection Notes

Select this component when space constraints require integrating both a high-current switch and a control transistor. The PNP BISS transistor is suitable for loads up to 3 A with low on-resistance. The integrated NPN RET simplifies gate drive circuits by eliminating external base resistors, reducing design complexity and board area.

Part Context

This device belongs to the BISS (Breakthrough In Small Signal) transistor family from NXP Semiconductors, now managed by Nexperia. It represents a specialized integration strategy combining discrete power switching capabilities with control logic components in a standard SO8 footprint to optimize PCB real estate.

Replacement Considerations

Check for direct pin-compatible alternatives within the Nexperia BISS portfolio. Verify that any substitute maintains the -20 V PNP and 50 V NPN voltage ratings along with the 3 A current capacity. Ensure the replacement package remains SOT96-1 (SO8) for mechanical compatibility.
