PUMB1,115

Overview

The PUMB1,115 is a dual pre-biased NPN transistor array manufactured by Nexperia USA Inc. It integrates two NPN transistors with built-in biasing resistors in a compact SOT-363 (SC-88) surface-mount package. The device features a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 100 mA. Each transistor includes an internal base resistor of 22 kΩ and an emitter resistor of 22 kΩ. The unit dissipates up to 300 mW of power and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Integrates dual NPN transistors with fixed biasing resistors to simplify circuit design
• Provides low saturation voltage for efficient switching performance
• Utilizes a compact SOT-363 package suitable for space-constrained applications

Applications

• General-purpose switching circuits
• Driver stages for logic interfaces
• Level shifting applications

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm packaging configuration and compliance status. Ensure the component meets RoHS3 requirements for the intended market. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required. Compare the 22 kΩ internal resistance values against external resistor alternatives to determine if the integrated solution reduces board space and assembly costs. Verify that the 50 V rating and 100 mA current capacity meet the load requirements.

Part Context

This part belongs to the PUMB series of pre-biased bipolar transistors from Nexperia. These devices are designed to replace multiple discrete components, reducing footprint and simplifying PCB layout. The PUMB1 variant specifically offers dual NPN configurations with standardized resistor values for common digital switching tasks.

Replacement Considerations

Check for direct substitutes such as the PUMB16 or similar Nexperia dual NPN arrays. Verify pin compatibility and electrical parameters before substitution. Ensure any replacement maintains the same package type and thermal characteristics.
