PBLS2024D,115

Overview

The PBLS2024D is a PNP low VCEsat Breakthrough In Small Signal (BISS) transistor and an NPN Resistor-Equipped Transistor (RET) housed in a SOT457 (SC-74) surface-mounted package. The PNP BISS loadswitch supports a collector current of -1.8 A with a maximum collector-emitter voltage of -20 V, featuring a typical saturation resistance of 78 mΩ at full load. The integrated NPN RET provides a bias resistor of 22 kΩ with a collector-emitter voltage rating of 50 V and an output current limit of 100 mA. This dual-component configuration enables space-saving circuit designs by reducing the overall component count.

Feature Summary

• Portable equipment

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as tape and reel pitch or quantity. Ensure that the device marking code matches the required identification for assembly processes. Confirm compliance with relevant environmental directives prior to final procurement decisions.

Selection Notes

Select this component when space constraints require integrating both a high-current load switch and a driver transistor into one footprint. Evaluate the thermal resistance characteristics relative to the intended PCB copper area and ambient temperature conditions. Ensure the input drive signals align with the specified base current limits for optimal saturation performance.
