PUMD6/ZLF

Overview

The PUMD6/ZLF is a dual pre-biased NPN transistor array manufactured by Nexperia USA Inc. in a 6-TSSOP surface-mount package. It integrates two NPN bipolar junction transistors with built-in biasing resistors to simplify circuit design and reduce component count. The device features a collector-emitter breakdown voltage of 50V and a maximum continuous collector current of 100mA per channel. Internal resistor values are typically 10 kΩ for the base resistor (R1) and 47 kΩ for the emitter resistor (R2). With a maximum power dissipation of 300mW, it is suitable for compact digital logic interfacing and switching applications requiring minimal external components.

Feature Summary

• Integrates dual NPN transistors with fixed biasing resistors to minimize board space and assembly steps
• Provides consistent DC current gain characteristics through internal resistance networks
• Utilizes a leadless 6-terminal TSSOP package optimized for high-density surface-mount layouts

Applications

• Digital logic level shifting and interface circuits
• General-purpose switching applications in consumer electronics
• Driver stages for low-current loads in embedded systems

Procurement Notes

Verify the ZLF suffix indicates lead-free compliance when sourcing. Confirm the 6-TSSOP package variant matches your PCB footprint requirements. Ensure the 50V rating aligns with your circuit's maximum operating voltage. Check for RoHS3 certification status if required by your manufacturing standards. Validate supplier documentation against the official Nexperia datasheet for the PUMD6 series.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required to save space. Compare the 10kΩ/47kΩ internal resistor values against your specific drive requirements. Consider the 300mW power dissipation limit for thermal management in dense assemblies. Evaluate the 6-TSSOP package dimensions against available board real estate. Ensure the 50V breakdown voltage exceeds your peak circuit voltages.

Part Context

The PUMD6 belongs to Nexperia's family of pre-biased resistor-equipped transistors designed to replace discrete BJT and resistor combinations. These arrays streamline the design of switching and logic interface circuits by reducing part count. The ZLF designation typically denotes lead-free construction, adhering to environmental directives. This component serves as a direct replacement for similar dual NPN pre-bias devices from other manufacturers offering equivalent electrical specifications and pinouts.

Replacement Considerations

Compatible substitutes include the PUMH9 for NPN configurations or PUMB6 for PNP equivalents within the same Nexperia portfolio. Verify that alternative parts match the 6-TSSOP package and 50V/100mA ratings. Cross-reference internal resistor values to ensure circuit functionality remains unchanged.
