PUMD9/ZLF

Overview

The Nexperia PUMD9/ZLF is a dual pre-biased transistor array housed in a 6-TSSOP (SOT-363) surface-mount package. It integrates one NPN and one PNP bipolar junction transistor, each with built-in bias resistors to simplify circuit design. The device supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. Internal resistor values are specified as 10 kΩ for the base (R1) and 47 kΩ for the emitter (R2). With a transition frequency ranging from 180MHz to 230MHz and a power dissipation capacity of 200mW, it is designed for high-speed digital switching applications.

Feature Summary

• Integrates complementary NPN and PNP transistors with embedded bias resistors to reduce external component count
• Qualified according to AEC-Q101 standards for automotive reliability requirements
• Optimized for cost-saving implementation in digital logic and signal processing circuits

Applications

• Digital input buffering for microcontrollers and logic gates
• Load switching in automotive control modules
• Interface circuits between different voltage domains in industrial equipment

Procurement Notes

Verify that the suffix /ZLF indicates lead-free compliance consistent with RoHS3 directives. Confirm the specific tape-and-reel quantity matches the manufacturing standard of 3,000 units per reel. Ensure the ordering code aligns with the exact pinout configuration required for the target PCB footprint to avoid assembly errors.

Selection Notes

Select this component when a compact solution requires both NPN and PNP switching capabilities within a single package. The integrated resistors eliminate the need for external biasing networks, saving board space. Verify that the 50V breakdown voltage and 100mA current rating exceed the maximum operational loads of the intended application circuit.

Part Context

This part belongs to the Nexperia PUMD9 family of resistor-equipped double transistors. The ZLF suffix denotes a lead-free finish, adhering to environmental regulations. It serves as a direct replacement for discrete resistor-transistor combinations, offering improved consistency and reduced assembly time compared to manual soldering of individual components.

Replacement Considerations

Direct functional equivalents include the PUMD9-QX and PUMD9,115 variants. These parts share identical electrical characteristics and pin configurations. Verify that any substitute maintains the same AEC-Q101 qualification status if automotive reliability is required.
