PUMD6/ZLX

Overview

The Nexperia PUMD6/ZLX is a dual NPN pre-biased resistor transistor (NPN+NPN) in a US SOT323 package. It integrates two NPN transistors with base resistors for simplified circuit design. Key electrical parameters include a maximum collector-emitter voltage (Vceo) of 50 V, a maximum collector-base voltage (VCBO) of 50 V, and a maximum emitter-base voltage (VEBO) of 10 V. The device supports a maximum DC collector current (Idc) of 100 mA and has a minimum DC current gain (hFE) of 100. Power dissipation is rated at 200 mW, with an operating temperature range from -65°C to +150°C.

Feature Summary

• Integrated dual NPN configuration with built-in base resistors reduces component count and board space.
• High switching speed capability suitable for digital logic applications.
• Automotive qualified under AEC-Q101 standards for enhanced reliability.

Applications

• Digital logic level shifting
• Switching circuits in consumer electronics
• General-purpose amplification

Procurement Notes

Verify the specific suffix ZLX against official Nexperia documentation to confirm tape and reel specifications. Ensure compatibility with automated pick-and-place equipment by checking reel dimensions and leader/trailer requirements. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before procurement.

Selection Notes

Select this component when a compact dual NPN solution with integrated biasing is required. Compare hFE ranges and base resistance values against alternative pre-biased transistor pairs. Consider the SOT323 footprint constraints and thermal performance limits relative to the application's power dissipation needs.

Part Context

This part belongs to the PUMD series of pre-biased transistors from Nexperia. These devices are designed to replace multiple discrete components, simplifying assembly. The US package refers to the SOT323 surface-mount form factor, widely used in portable and space-constrained electronic designs.

Replacement Considerations

Check for direct equivalents such as the PUMD6 or similar NPN+NPN pre-biased transistors in SOT323 packages. Verify pinout compatibility and electrical parameter overlaps before substitution. Consult Nexperia's cross-reference tools for validated alternatives.
