PMBT3904RAZ

Overview

The PMBT3904RAZ is a double NPN switching transistor manufactured by Nexperia, housed in an ultra-small DFN1412-6 (SOT1268) leadless surface-mounted device plastic package. It features a low profile of 0.5 mm height and provides two independent NPN transistors within a single component to reduce board space and assembly costs. Key electrical parameters include a collector-emitter voltage (VCEO) of 40 V, a continuous collector current (IC) of 200 mA per transistor, and a DC current gain (hFE) ranging from 100 to 300 at IC = 10 mA. The transition frequency (fT) is specified at 300 MHz, with a total power dissipation of 480 mW for the device.

Feature Summary

• Leadless ultra-small SMD plastic package design
• Reduces component count and pick-and-place costs
• Low package height of 0.5 mm

Applications

• General-purpose switching
• Amplification

Procurement Notes

Verify the specific ordering suffix 'Z' against the manufacturer's official documentation to confirm reel packaging specifications. Ensure the DFN1412-6 footprint matches the PCB layout requirements. Confirm RoHS compliance status through the latest product data sheet before finalizing procurement orders.

Selection Notes

Select this component when dual NPN switching functionality is required in a minimal footprint. The DFN1412-6 package offers thermal enhancement compared to standard small outlines. Verify that the 40 V rating and 200 mA current limits meet the circuit requirements. Consider the 0.5 mm height constraint for thin-profile designs.

Part Context

This part belongs to the PMBT3904 series of general-purpose NPN switching transistors. The 'RA' designation specifically indicates the DFN1412-6 package variant, distinguishing it from other packages like SOT23 or SC-88 found in the broader family. The 'Z' suffix typically denotes tape and reel packaging for automated assembly.

Replacement Considerations

Direct pin-compatible replacements in the same package require checking the datasheet for identical pinout configurations. Other Nexperia parts in the PMBT3904 family may offer different package options but must be verified for electrical equivalence.
