PUMH7H-QX

Overview

The PUMH7H-QX is an NPN pre-biased transistor array manufactured by Nexperia USA Inc. It integrates two NPN transistors with base resistors into a single surface-mount package. The device features a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Each transistor includes a typical base resistor value of 4.7 kΩ. The component is housed in a 6-TSSOP (SC-88, SOT-363) package with dimensions of 2.2 x 1.35 x 1.1 mm. It supports a maximum power dissipation of 300 mW and operates at temperatures up to +150 °C. The part is qualified under the AEC-Q100 standard for automotive applications.

Feature Summary

• Integrated dual NPN configuration with built-in base resistors simplifies circuit design by reducing external component count.
• Automotive-grade qualification ensures reliability and performance consistency in demanding vehicle environments.
• Compact surface-mount packaging facilitates high-density PCB layout and automated assembly processes.

Applications

• General-purpose switching in automotive electronic control units
• Driver circuits for low-power loads in vehicle interior systems
• Signal level translation and buffering in automotive communication interfaces

Procurement Notes

Verify the specific suffix '-QX' against official Nexperia documentation to confirm it denotes the correct tape-and-reel packaging format and any distinct marking or quality certifications. Ensure the ordering part number matches the exact electrical specifications required for the target application, as suffixes can indicate variations in reel size or handling instructions.

Selection Notes

Select this component when a dual NPN pre-biased solution is required for space-constrained automotive designs. The 4.7 kΩ base resistor value suits moderate drive currents. Compare the 50 V rating and 100 mA current limit against load requirements. Consider the 6-TSSOP footprint compatibility during PCB layout phase to ensure mechanical fit and thermal performance meet system constraints.
