PUMD6H-QX

Overview

The PUMD6H-QX is a digital transistor array manufactured by Nexperia USA Inc., featuring two NPN transistors with integrated biasing resistors in a compact surface-mount package. This component is designed to simplify circuit design by reducing the number of external components required for switching applications. It operates with a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA, making it suitable for low-power signal switching and logic interface tasks. The device includes internal base and emitter resistors to facilitate direct connection to logic outputs.

Feature Summary

• Integrated dual NPN configuration with built-in biasing resistors
• Automotive-grade qualification ensuring reliability under varying conditions
• Compact SOT-363 packaging for efficient PCB space utilization

Applications

• Logic level shifting between different voltage domains
• Switching applications in automotive control modules
• Interface circuits for microcontroller GPIO expansion

Procurement Notes

Verify the specific suffix -QX indicates AEC-Q101 automotive qualification when sourcing. Confirm the manufacturer is Nexperia USA Inc. or an authorized distributor. Check RoHS compliance status as per latest datasheet revisions. Ensure the package type matches the design footprint requirements before ordering.

Selection Notes

Select this part when a dual NPN digital transistor solution is needed for automotive or high-reliability industrial applications. Compare internal resistor values against the target logic voltage levels to ensure proper biasing. Consider the thermal dissipation capabilities within the SOT-363 package for the expected duty cycle.

Part Context

The PUMD6H-QX belongs to Nexperia's portfolio of pre-biased digital transistors, specifically tailored for automotive electronics. It is part of the PUM series which offers various configurations of NPN and PNP pairs. The -QX suffix denotes automotive grade qualification, distinguishing it from standard commercial variants like the PUMD6H.

Replacement Considerations

Direct substitutes include other AEC-Q101 qualified dual NPN digital transistors in SOT-363 packages from Nexperia or competitors. Verify pinout compatibility and internal resistor values (typically 10kΩ base, 47kΩ emitter) before swapping. Ensure the replacement meets the same 50V Vceo and 100mA Ic ratings.
