PBLS2022D,115

Overview

The PBLS2022D,115 is a dual digital transistor in a SOT457 (SC-74) package. It integrates 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 -20 V and continuous current of -1.8 A, with a typical saturation resistance of 78 mΩ at -1.8 A. The NPN RET features a 4.7 kΩ bias resistor and a 50 V collector-emitter voltage rating. The device operates between -55 °C and +150 °C and is qualified to AEC-Q101 standards.

Feature Summary

• Combines a low saturation voltage PNP BISS transistor with an NPN resistor-equipped transistor in a single compact surface-mount package.
• Offers a space-saving solution that reduces component count compared to discrete implementations.
• Features a low threshold voltage below 1 V, requiring less drive power than comparable MOSFETs.
• Qualified for automotive applications under the AEC-Q101 stress test standard.

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 current catalog to confirm packaging details such as tape and reel pitch. Confirm the active status of the component through official Nexperia channels, as availability may vary by region. Ensure the requested quantity matches the minimum packing quantity defined in the official documentation before finalizing orders.

Selection Notes

Select this component when a design requires both high-current switching capability and integrated base drive logic within a limited footprint. The low VCEsat characteristic makes it suitable for applications where minimizing conduction loss is critical. Verify that the required input impedance aligns with the internal 4.7 kΩ bias resistor value to ensure proper logic level interfacing.

Part Context

This part belongs to the Nexperia PBLS series of loadswitch double transistors. These devices are designed to replace multiple discrete components, simplifying PCB layout. The SC-74 package provides a small outline for dense mounting. The series typically includes variants with different voltage and current ratings to suit various power management needs.

Replacement Considerations

Check for direct pin-compatible alternatives within the same PBLS family or other manufacturers' dual transistor offerings. Ensure any substitute maintains the same SOT457 package dimensions and electrical characteristics, particularly the saturation voltage and current ratings, to guarantee functional equivalence.
