PUMH7HX

Overview

The PUMH7HX is a dual NPN pre-biased transistor array manufactured by Nexperia USA Inc. It integrates two NPN bipolar junction transistors with internal biasing resistors in a compact surface-mount package. The device features a collector-emitter breakdown voltage of 50V and a maximum continuous collector current of 100mA. Each transistor includes an integrated base resistor, typically valued at 4.7 kΩ, simplifying circuit design by reducing component count. The unit operates within a temperature range of -55°C to +150°C and is housed in a 6-TSSOP (SC-88/SOT-363) package. It is qualified for automotive applications under the AEC-Q100 standard.

Feature Summary

• Integrated dual NPN configuration with built-in biasing resistors for simplified drive circuits
• Automotive-grade qualification ensuring reliability in demanding environments
• Compact surface-mount packaging suitable for high-density board layouts

Applications

• General-purpose switching applications in consumer electronics
• Driver circuits for low-power loads in automotive systems
• Logic level translation and buffering in digital interfaces

Procurement Notes

Verify the specific suffix 'HX' against official Nexperia documentation to confirm exact tape-and-reel specifications or marking codes. Confirm AEC-Q100 compliance status directly with the manufacturer for critical automotive designs. Ensure the 6-TSSOP footprint matches the target PCB layout constraints. Check for any recent PCN updates regarding assembly sites or material changes before finalizing procurement.

Selection Notes

Select this component when a dual NPN solution with integrated biasing is required to save board space and reduce assembly costs. Compare the 4.7 kΩ internal resistance value against the driving source capabilities to ensure adequate base current. Consider the 50V voltage rating relative to the maximum operating voltage. Evaluate the thermal performance within the 6-TSSOP package for the expected power dissipation levels.

Part Context

The PUMH7 series represents a family of pre-biased transistors designed to replace discrete resistor-transistor networks. The PUMH7HX variant specifically denotes the dual NPN configuration within this lineup. These devices are part of Nexperia's broader portfolio of small-signal transistors aimed at minimizing external component requirements in modern electronic designs.

Replacement Considerations

Consult official Nexperia substitution guides for verified equivalents. Generic replacements may differ in internal resistor tolerance or hFE characteristics. Verify pinout compatibility and thermal resistance values before implementing any alternative components.
