PBLS4003V,115

Overview

The PBLS4003V,115 is a dual transistor array in an SOT666 package, integrating a PNP low VCEsat Breakthrough In Small Signal (BISS) transistor and an NPN Resistor-Equipped Transistor (RET). The PNP section supports a collector-emitter voltage of -40 V and a continuous collector current of -500 mA, with a typical saturation resistance of 440 mΩ. The NPN section handles up to 50 V collector-emitter voltage and 100 mA output current, featuring a 10 kΩ bias resistor. Total power dissipation is rated at 300 mW, with an operating temperature range 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 bias resistors directly into the transistor structure
• Offers low drive power requirements due to low threshold voltage characteristics

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm packaging details and manufacturing origin. Ensure the selected variant matches the required tape and reel pitch specifications for automated assembly processes. Cross-reference the marking code K3 on the device body to confirm authenticity and correct part identification before integration into production lines.

Selection Notes

Select this component when a compact solution is required that combines load switching capabilities with signal control functions. The integrated bias resistor simplifies circuit design by eliminating external base resistors for the NPN section. Consider the thermal resistance and total power dissipation limits when designing for high ambient temperatures or dense PCB layouts to ensure reliable operation within specified junction temperature constraints.

Part Context

This device belongs to the PBLS4003 series, which includes the PBLS4003Y variant housed in an SOT363 package. Both variants share identical electrical characteristics but differ in physical footprint and pinout configuration. The PBLS4003V utilizes the SOT666 package, offering a distinct mechanical profile suitable for applications where the SC-88 form factor is unsuitable while maintaining similar functional performance.

Replacement Considerations

The PBLS4003Y serves as a functional equivalent with identical electrical parameters but uses the SOT363 package. Direct substitution requires verifying PCB footprint compatibility between SOT666 and SOT363 packages.
