PBLS4003Y,115

Overview

The PBLS4003Y,115 is a digital transistor in an SOT363 (SC-88) package containing a PNP low VCEsat Breakthrough In Small Signal (BISS) transistor and an NPN Resistor-Equipped Transistor (RET). The PNP section provides a collector-emitter voltage of -40 V and continuous current of -500 mA with a typical saturation resistance of 440 mΩ. The NPN section offers a collector-emitter voltage of 50 V, output current of 100 mA, and a bias resistor of 10 kΩ.

Feature Summary

• Combines a low VCEsat BISS transistor and an NPN RET in one space-saving package
• Features a low threshold voltage compared to MOSFETs for reduced drive power requirements
• Reduces component count through integrated resistor-equipped transistor functionality

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required packing method, as the datasheet indicates different suffixes correspond to distinct tape and reel configurations. Confirm the manufacturer origin code on the marking aligns with supply chain requirements. Ensure the component status is current by consulting the latest product data sheet before initiating design or procurement processes.

Selection Notes

Select this component when a compact solution integrating both a high-current PNP load switch and a logic-compatible NPN switch is required. The low saturation resistance of the PNP device supports efficient power handling, while the integrated bias resistor simplifies interface with microcontrollers. Verify that the thermal resistance and power dissipation limits suit the intended PCB footprint and ambient temperature conditions.

Part Context

This part belongs to the Nexperia PBLS series of digital transistors, specifically designed as load switches. It is functionally related to the PBLS4003V, which utilizes an SOT666 package instead of the SOT363 used here. Both variants share identical electrical characteristics but differ in physical dimensions and pinout compatibility for surface-mount assembly.

Replacement Considerations

The PBLS4003V is a direct functional equivalent with identical electrical specifications but uses an SOT666 package. Substitution requires verifying mechanical fit and pin alignment due to the package difference. Other PBLS series members may offer different voltage ratings or resistor values.
