PUMX2,125

Overview

The PUMX2 is an NPN/NPN general-purpose double transistor housed in a TSSOP6 (SOT363-3) surface-mounted device package. It contains two independent transistors within a single component, offering a collector-emitter voltage of 50 V and a continuous collector current of 150 mA per transistor. The DC current gain ranges from 120 to 560 at 1 mA. Total power dissipation is limited to 300 mW for the device and 180 mW per transistor at 25 °C ambient temperature. The transition frequency is specified at 100 MHz.

Feature Summary

• Integrates two NPN transistors into a compact SMD plastic package to reduce component count
• Simplifies circuit design by consolidating dual transistor functions
• Reduces pick and place costs through small footprint implementation

Applications

• General-purpose switching
• Amplification circuits

Procurement Notes

Verify that the specific order suffix matches the required packaging format before procurement. Confirm that the application does not require automotive qualification, as this product version is non-automotive qualified. Ensure thermal management aligns with the specified junction-to-ambient resistance limits during operation.

Selection Notes

Select this component when space constraints necessitate a dual-transistor solution in a TSSOP6 package. Verify that the required collector-emitter voltage does not exceed 50 V and that the operating current remains within the 150 mA limit. Consider the 300 mW total power dissipation capability relative to the expected thermal environment.

Part Context

This component belongs to Nexperia's portfolio of general-purpose discrete semiconductors designed for surface-mount assembly.
