PBLS1502Y,115

Overview

The PBLS1502Y is a 15 V PNP BISS loadswitch integrating a low VCEsat PNP transistor and an NPN resistor-equipped transistor in a single SOT363 package. The PNP section (TR1) supports a collector current of -500 mA with a maximum on-resistance of 500 mΩ at -500 mA. The NPN section (TR2) features a 50 V collector-emitter voltage rating, 100 mA output current, and a typical bias resistor of 4.7 kΩ. Total power dissipation is limited to 300 mW per device.

Feature Summary

• Combines a low saturation voltage PNP transistor and an NPN transistor with integrated bias resistors into one compact component.
• Offers reduced drive power requirements compared to MOSFETs due to lower threshold voltage characteristics.
• Provides space-saving integration that reduces overall component count in circuit designs.

Applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current database to confirm availability status. The datasheet indicates this product may be subject to change or end-of-life notices. Confirm the package type matches the required PCB footprint before procurement. Ensure compliance with the absolute maximum ratings during design validation.

Selection Notes

Select this component when space constraints require combining switching and control functions. The integrated NPN transistor simplifies drive circuits by eliminating external base resistors. Verify that the 15 V rating for the PNP side and 50 V rating for the NPN side meet the application voltage requirements. Consider the thermal resistance of the SOT363 package for heat dissipation calculations.
