PUMB2F

Overview

The PUMB2F is a pre-biased dual bipolar junction transistor (BJT) array manufactured by Nexperia USA Inc. It integrates two PNP transistors with built-in biasing resistors in a compact surface-mount package. Key electrical parameters include a collector-emitter breakdown voltage of 50V, a maximum collector current of 100mA, and a transition frequency of 180MHz. The device dissipates up to 300mW of power and features an integrated base resistor of 47kOhms. It is housed in a 6-TSSOP package designed for automated assembly processes.

Feature Summary

• Integrates dual PNP transistors with pre-biased resistors to simplify circuit design
• Optimized for high-speed switching applications with specified transition frequency
• Compact surface-mount packaging facilitates efficient PCB layout

Applications

• Logic level shifting circuits
• Switching applications in consumer electronics
• Interface drivers for microcontroller outputs

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct pinout and electrical characteristics. Confirm that the 6-TSSOP package variant matches the design requirements. Cross-reference the datasheet revision date to ensure compliance with current manufacturing standards. Validate thermal performance constraints relative to the intended operating environment before finalizing procurement decisions.

Selection Notes

Select this component when space-saving integration of dual PNP switches is required. The pre-biased configuration reduces external component count compared to discrete solutions. Ensure the 50V voltage rating and 100mA current limit align with the load requirements. Consider the 180MHz frequency specification for signal integrity in high-speed digital interfaces.
