PUMH9,115

Overview

The Nexperia PUMH9,115 is a dual NPN Resistor-Equipped Transistor (RET) housed in a SOT363-3 (SC-88/TSSOP6) surface-mount package. It integrates two independent NPN transistors with built-in bias resistors: R1 = 10 kΩ and R2 = 47 kΩ. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, an output current capability of 100 mA per transistor, and a DC current gain (hFE) minimum of 100 at IC = 5 mA. The device features a transition frequency (fT) of 230 MHz and operates within a junction temperature range up to 150 °C.

Feature Summary

• Integrates dual NPN transistors with fixed internal bias resistors to simplify circuit design
• Reduces component count and pick-and-place costs by replacing discrete resistor-transistor combinations
• Provides high DC current gain and low saturation voltage for efficient digital switching

Applications

• Digital applications in automotive and industrial segments
• Cost-saving alternative for BC847 series in digital logic circuits
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix '115' corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the SOT363-3 footprint matches your PCB design guidelines. Ensure compliance with RoHS and REACH directives as stated in the product data sheet before finalizing procurement specifications.

Selection Notes

Select this component when space constraints require a dual NPN solution with integrated biasing. The 10 kΩ input resistor suits standard logic levels, while the 47 kΩ pull-down resistor ensures defined off-states. Verify thermal dissipation requirements against the 200 mW per transistor limit on FR4 PCBs to ensure reliable operation under continuous load conditions.

Part Context

The PUMH9 belongs to Nexperia's family of Resistor-Equipped Transistors (RETs). It serves as the NPN/NPN complement to the PUMB9 (PNP/PNP) and PUMD9 (NPN/PNP). This series is designed to replace multiple discrete components, offering a compact alternative for general-purpose digital switching and signal conditioning tasks in consumer and industrial electronics.

Replacement Considerations

Direct functional equivalents include the PUMH9,115 from other manufacturers if pinout and electrical characteristics match. For complementary polarity needs, consider the PUMB9 or PUMD9 variants. Verify that any substitute maintains the same SOT363-3 package dimensions and bias resistor values to ensure board compatibility.
