PUMB20,115

Overview

The PUMB20,115 is a dual pre-biased NPN digital transistor manufactured by Nexperia USA Inc. It integrates two NPN transistors with internal biasing resistors within a compact SOT-363 (TSSOP6) surface-mount package. The device supports a maximum continuous collector current of 100 mA and withstands a collector-emitter voltage of 50 V. Key electrical characteristics include a typical input resistance (R1) of 47 kΩ and an output resistance (R2) of 47 kΩ. The component operates reliably across a temperature range from -65°C to +150°C, ensuring stability in diverse electronic environments.

Feature Summary

• Integrates dual NPN transistors with built-in biasing resistors to simplify circuit design
• Provides high DC current gain for efficient signal switching applications
• Features low saturation voltage to minimize power dissipation during operation

Applications

• General-purpose switching circuits
• Driver stages for logic interfaces
• Level shifting between different voltage domains

Procurement Notes

Verify the specific ordering code PUMB20,115 against official Nexperia documentation to confirm package type and electrical tolerances. Ensure compatibility with standard SMT reflow profiles for the TSSOP6 housing. Cross-reference datasheet parameters such as thermal resistance and maximum power dissipation with system requirements before finalizing procurement decisions.

Selection Notes

Select this component when a dual NPN configuration with integrated base resistors is required to reduce board space and assembly steps. Compare the 47 kΩ resistor values against target drive currents to ensure adequate base drive. Verify that the 50 V breakdown voltage exceeds the maximum operating voltage of the application circuit.

Part Context

This part belongs to the Nexperia PUMB series of pre-biased bipolar junction transistors. These devices are designed to replace discrete resistor-transistor networks, offering a compact solution for digital switching tasks. The series is widely used in consumer electronics and industrial control systems where space efficiency and simplified schematics are prioritized.

Replacement Considerations

Compatible substitutes include other dual NPN pre-biased transistors in SOT-363 packages, such as the PUMH20 or PUMD20 series, provided pin configurations and electrical ratings match the original design requirements.
