PUMB18-QX

Single Bipolar Transistors Overview

The PUMB18-QX is a dual digital transistor from Nexperia, featuring integrated resistors for simplified circuit design. It combines one NPN and one PNP bipolar junction transistor within a single SOT363 (SC-88) surface-mount package. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 300 mW, with an operating temperature range spanning from -65 °C to +150 °C. This configuration provides high integration density for space-constrained applications.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm packaging details and compliance status. Ensure that the ordering code matches the required tape-and-reel specifications for automated assembly processes. Cross-reference the part number with the latest datasheet revision to confirm pinout compatibility and electrical characteristics before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a mixed NPN/PNP digital transistor solution is required in a small outline package. The integrated resistor network reduces board space and assembly costs compared to discrete solutions. Verify that the 50 V voltage rating and 100 mA current capacity meet the specific load requirements of the target application circuit.

Single Bipolar Transistors Part Context

This part belongs to Nexperia's portfolio of digital transistors, which integrate transistors and resistors to simplify circuit design. The PUMB series specifically offers complementary configurations. The QX suffix typically denotes specific packaging or handling variations within the manufacturer's product line, distinct from standard commercial variants.

Single Bipolar Transistors Replacement Considerations

Direct replacements must match the SOT363 package and contain both NPN and PNP structures with similar voltage and current ratings. Verify resistor values and hFE characteristics to ensure functional equivalence in existing designs.
