PQMD3Z

Overview

The PQMD3Z is a dual NPN transistor in an SOT23 (TO-236AB) plastic surface-mounted device package. It features a common emitter configuration with the emitters connected internally, functioning as two separate NPN transistors within a single component. The device is designed for general-purpose switching and amplification applications. It operates with a collector-emitter voltage of -50 V and a collector current of -100 mA. The unit is Pb-free, RoHS compliant, and halogen-free.

Feature Summary

• Dual NPN transistor structure in a compact SOT23 package
• Common emitter configuration for simplified circuit design
• General-purpose switching and amplification capabilities

Applications

• General-purpose switching circuits
• Signal amplification stages
• Logic level translation interfaces

Procurement Notes

Verify the specific suffix codes against official Nexperia documentation to ensure correct binning and tape-and-reel specifications. Confirm that the ordering part number matches the required electrical tolerance and packaging format for your production line requirements.

Selection Notes

Select this component when space-constrained designs require two NPN transistors with common emitters. Ensure the application voltage does not exceed the -50 V collector-emitter rating and that the total current remains within the -100 mA limit per transistor.

Part Context

This component belongs to Nexperia's portfolio of small-signal bipolar junction transistors. It is part of the PQM series, which provides dual transistor solutions in standard surface-mount packages to reduce board space and assembly costs compared to discrete single transistors.

Replacement Considerations

Check for direct equivalents such as the BC847D or similar dual NPN SOT23 devices from other manufacturers. Verify pinout compatibility and electrical parameter alignment before substitution.
