PUMH2,115

Overview

The PUMH2,115 is a dual NPN digital transistor manufactured by Nexperia USA Inc. It integrates two NPN transistors with built-in biasing resistors within a compact SOT-363 (SC-88) surface-mount package. The device features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 100 mA. Each transistor includes an input resistor of 4.7 kΩ and a base-emitter shunt resistor of 47 kΩ. The component operates reliably across a temperature range from -55 °C to +150 °C, with a total power dissipation capability of 225 mW.

Feature Summary

• Dual NPN configuration with integrated biasing resistors for simplified circuit design
• Compact SOT-363 surface-mount package optimized for space-constrained applications
• High thermal stability supporting operation up to 150 °C junction temperature

Applications

• General-purpose switching in portable consumer electronics
• Logic level translation between microcontrollers and peripheral devices
• Driver circuits for low-power loads such as LEDs or relays

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and reel specifications. Ensure compliance with RoHS directives and check for AEC-Q101 automotive qualification status if required for the target application environment.

Selection Notes

Select this component when a dual NPN switch with fixed internal biasing is required. Compare the 4.7 kΩ input resistance against other variants like PUMH1 or PUMH20 if different drive currents are needed. Confirm that the 50 V voltage rating meets the system's maximum operating conditions.

Part Context

This part belongs to the PUMH series of pre-biased NPN digital transistors. It serves as a functional alternative to discrete transistor-resistor networks, reducing board space and assembly complexity. The SOT-363 package is standard for low-pin-count dual transistor arrays in modern electronics.

Replacement Considerations

Direct substitutes include PUMH1,115 and PUMH20,115, which share the same package but differ in internal resistor values. Verify pinout compatibility before swapping.
