PUMB4,115

Overview

The PUMB4,115 is a dual PNP digital transistor array manufactured by Nexperia USA Inc., housed in a compact 6-TSSOP surface-mount package. It integrates two independent PNP transistors with built-in biasing resistors to simplify circuit design and reduce component count. The device supports a maximum collector current of 100 mA and withstands a collector-emitter voltage of -50 V. Each transistor includes an internal base resistor of 10 kOhms, providing a DC current gain (hFE) of at least 200 under specified test conditions. With a power dissipation rating of 200 mW and an operating temperature range from -65°C to +150°C, it is suitable for high-density PCB layouts requiring reliable switching performance.

Feature Summary

• Dual integrated PNP transistors with pre-biased resistors for simplified logic interfacing
• Compact 6-pin TSSOP footprint designed for space-constrained surface-mount applications
• High DC current gain ensures efficient switching with minimal drive current requirements

Applications

• Logic level shifting and voltage translation between different signal domains
• General-purpose switching in embedded control circuits
• Driver stages for low-current loads in consumer electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout compatibility and packaging type. Ensure that the procurement source provides valid RoHS compliance documentation consistent with REACH regulations. Cross-reference the part number with official Nexperia distribution channels to avoid counterfeit components and ensure traceability for quality assurance purposes.

Selection Notes

Select this component when a dual PNP configuration with fixed biasing is required to minimize external passive components. Compare the 10 kOhm internal resistance against application drive capabilities to ensure adequate base current. Evaluate the thermal constraints within the 6-TSSOP package to maintain junction temperatures within the specified operational limits during continuous duty cycles.

Part Context

This component belongs to the PUMB series of dual PNP digital transistors offered by Nexperia. It shares the same functional architecture as other members in the family but differs in internal resistor values and polarity specifications. The series is engineered to replace discrete resistor-transistor combinations, offering a standardized solution for logic interface and switching tasks across various industrial and consumer electronic platforms.

Replacement Considerations

Direct substitutes include other dual PNP digital arrays with identical pinouts and similar electrical ratings, such as the PUMH4 or PUMH11 if NPN configurations are adaptable. Verify that any replacement maintains the 10 kOhm base resistance and -50 V voltage rating to ensure circuit compatibility without redesign.
