PUMD48,115

Overview

The PUMD48,115 is a dual Resistor-Equipped Transistor (RET) containing one NPN and one PNP transistor in a SOT363-3 package. It features built-in bias resistors: TR1 (NPN) has R1=47 kΩ and R2=47 kΩ; TR2 (PNP) has R1=2.2 kΩ and R2=47 kΩ. Key electrical parameters include a collector-emitter voltage of 50 V, output current of 100 mA, and total power dissipation of 300 mW at 25 °C. The NPN transistor offers a DC current gain of 80 at 5 mA, while the PNP provides 100 at 10 mA. Transition frequencies are 230 MHz for NPN and 180 MHz for PNP.

Feature Summary

• Integrates NPN/PNP transistors with specific internal bias resistors to simplify circuit design.
• Reduces component count and pick-and-place costs through a compact surface-mount package.
• Provides high output current capability suitable for driving peripheral loads.

Applications

• Low current peripheral driver
• Control of IC inputs
• Replaces general-purpose transistors in digital applications

Procurement Notes

Verify the ordering suffix matches the required packaging format before purchase. Confirm that the device meets RoHS compliance standards for your region. Ensure the PCB footprint aligns with the SOT363-3 outline dimensions provided in the datasheet. Check for any specific marking code requirements related to manufacturing site codes.

Selection Notes

Select this component when space constraints require a dual transistor solution with integrated base resistors. Compare the specific resistor values (47 kΩ/2.2 kΩ input) against circuit requirements. Consider the thermal resistance characteristics if operating near ambient temperature limits. Verify compatibility with standard SMD reflow soldering profiles.

Part Context

The PUMD48 belongs to Nexperia's family of NPN/PNP resistor-equipped double transistors. It serves as a compact alternative to discrete transistor pairs, offering reduced board space and assembly complexity. The SOT363-3 package allows for high-density mounting on printed-circuit boards, making it suitable for portable and consumer electronics designs.

Replacement Considerations

Check for direct cross-references within the PUMDxx series. Verify pinout compatibility if substituting with other RET devices. Ensure equivalent electrical ratings for voltage, current, and power dissipation are met by potential alternatives.
