PBSS5120T,215

Single Bipolar Transistors Overview

The PBSS5120T is a PNP low VCEsat transistor manufactured by Nexperia, housed in a small SOT23 surface-mounted device plastic package. It supports a collector-emitter voltage of -20 V and a continuous collector current of -1 A, with a peak pulse current capability of -2 A. The device features a maximum collector-emitter saturation resistance of 250 mΩ under specified pulsed conditions. Thermal performance includes a junction-to-ambient thermal resistance of 417 K/W in free air and 260 K/W when mounted on an FR4 PCB with a standard footprint. The component is qualified to the AEC-Q101 standard for automotive applications.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration before procurement. Confirm that the AEC-Q101 automotive qualification aligns with target application requirements. Ensure design parameters remain within the absolute maximum ratings defined in the datasheet to prevent device damage. Cross-reference the marking code %3K for manufacturing site identification during incoming inspection.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring efficient switching with minimal voltage drop across the collector-emitter junction. The low saturation resistance helps reduce power dissipation in high-current scenarios. Consider the SOT23 package constraints for thermal management and board space limitations. Verify compatibility with drive circuitry to ensure adequate base current for full saturation.

Single Bipolar Transistors Part Context

This part belongs to Nexperia's portfolio of low VCEsat transistors designed for general-purpose switching and muting applications. It serves as the PNP complement to the N-channel PBSS4120T. The series targets portable and consumer equipment where space efficiency and thermal performance are critical. It is widely used in battery-driven devices and mobile electronics.

Single Bipolar Transistors Replacement Considerations

The official NPN complement is the PBSS4120T. Direct pin-compatible replacements should be verified against the datasheet specifications for voltage, current, and saturation characteristics. Ensure any substitute maintains the same SOT23 package dimensions and thermal properties.
