PBLS4001V,115

Overview

The PBLS4001V,115 is a dual digital transistor in a SOT666 package, combining 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 up to -500 mA. The NPN section supports 50 V collector-emitter voltage and 100 mA output current. It features a typical bias resistor of 2.2 kΩ with a ratio of 1. Operating temperature ranges from -65 °C to +150 °C.

Feature Summary

• Combines a low saturation voltage PNP BISS transistor with an NPN RET for space-saving integration.
• Reduces component count by integrating internal bias resistors directly into the transistor structure.
• Offers low drive power requirements due to low threshold voltage characteristics compared to MOSFETs.

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 packaging configuration before purchase. Confirm that the SOT666 package variant aligns with the target PCB footprint design. Ensure compatibility with reflow soldering processes as specified in the thermal characteristics. Cross-reference the marking code K1 to validate the device identity upon receipt.

Selection Notes

Select this component when a combined load switch and logic interface is required within a compact form factor. The integrated bias resistor simplifies circuit design by eliminating external base resistors. Consider the thermal resistance limits when determining heat dissipation requirements for high-current applications.

Part Context

This part belongs to the PBLS4001 series, which includes variants like the PBLS4001Y in the SOT363 package. Both share identical electrical characteristics but differ in physical dimensions and pinout configurations. The series is designed for general-purpose switching and amplification tasks requiring minimal board space.

Replacement Considerations

The PBLS4001Y serves as a functional equivalent with identical electrical specifications. Verify that the SOT363 package dimensions are compatible with the existing PCB layout before substitution.
