PUMH9/ZLX

Overview

The PUMH9/ZLX is a dual NPN pre-biased transistor array manufactured by Nexperia USA Inc. It integrates two NPN transistors with built-in biasing resistors in a compact surface-mount package. The device features a maximum collector-emitter voltage (Vceo) of 50V and a continuous collector current (Ic) of 100mA. Internal resistor values include a base resistor (R1) of 10 kΩ and an emitter resistor (R2) of 47 kΩ. The component operates within a temperature range of -55°C to +150°C, with a maximum power dissipation of 300mW. It is housed in a 6-TSSOP (SOT-363) package.

Feature Summary

• Integrates two NPN transistors with fixed internal biasing resistors for simplified circuit design.
• Provides high DC current gain (hFE) of at least 100 under specified test conditions.
• Features low saturation voltage (Vce(sat)) of 100mV for efficient switching performance.
• Designed for surface-mount assembly in space-constrained applications.

Applications

• General-purpose switching circuits
• Driver stages for logic interfaces
• Level shifting applications

Procurement Notes

Verify the specific suffix ZLX against official Nexperia documentation to confirm tape-and-reel specifications or marking codes. Ensure compatibility with standard SMT processes. Check for RoHS compliance status as indicated in the latest datasheet revision. Confirm availability through authorized distributors given potential supply chain variations.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required. Compare R1 and R2 values against load requirements to ensure proper base drive. Consider the 6-TSSOP footprint for PCB layout constraints. Verify thermal management needs against the 300mW power dissipation limit in the intended enclosure.

Part Context

This part belongs to the Nexperia PUMH series of digital transistors. It shares the same core electrical characteristics and pinout as other variants like PUMH9,115 and PUMH9,135, differing primarily in packaging format or manufacturing batch identifiers. The ZLX suffix typically denotes a specific reel or labeling configuration rather than a change in electrical function.

Replacement Considerations

Direct substitutes include PUMH9,115 and PUMH9,135 from Nexperia, which share identical electrical parameters and pin configurations. Other compatible parts from different manufacturers must match the 50V Vceo, 100mA Ic, and 10kΩ/47kΩ resistor values.
