PUMD2/DG/B4X

Overview

The PUMD2/DG/B4X is a dual resistor-equipped transistor (RET) array manufactured by Nexperia USA Inc. It integrates one NPN and one PNP bipolar junction transistor within a single surface-mount package. The device features integrated base resistors to simplify circuit design and reduce component count. It is housed in the SOT-363 (SC-88) plastic package, designed for low-power applications requiring compact footprints. The unit operates with a maximum collector current of 100mA and supports a collector-emitter voltage of 50V. This configuration allows for efficient switching and logic interfacing in space-constrained electronic systems.

Feature Summary

• Integrates complementary NPN and PNP transistors with pre-biased resistors in a single compact package
• Utilizes SOT-363 (SC-88) surface-mount technology for minimal board space consumption
• Provides simplified circuit design through built-in base resistance for both transistor types

Applications

• General-purpose switching circuits
• Logic level translation interfaces
• Driver stages for low-current loads

Procurement Notes

Verify the specific suffix /DG/B4X against official Nexperia documentation to confirm packaging details and availability status. Ensure the ordering part number matches the required tape-and-reel specifications for automated assembly processes. Cross-reference the manufacturer's latest datasheet for any potential product discontinuation notices or alternative package options.

Selection Notes

Select this component when a complementary pair of pre-biased transistors is required in a minimal footprint. Compare the integrated resistor values against the target circuit biasing requirements. Consider the thermal dissipation capabilities of the SOT-363 package relative to the expected power load in the application environment.

Part Context

This part belongs to the PUMD series of resistor-equipped transistors from Nexperia. The series offers various combinations of NPN/PNP configurations with different resistor values. The PUMD2 variant specifically provides a matched pair for differential or push-pull applications where symmetry and compactness are critical design factors.

Replacement Considerations

Check for direct pin-compatible alternatives such as the PUMD2 from other manufacturers if supply constraints exist. Verify that substitute parts maintain identical resistor tolerances and transistor gain characteristics to ensure circuit performance stability.
