PUMH4/ZLX

Overview

The PUMH4/ZLX is a dual NPN pre-biased transistor manufactured by Nexperia USA Inc., housed in a 6-TSSOP (SOT-363) surface-mount package. It integrates two NPN transistors with internal base resistors, each rated at 10 kΩ. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA, with a total power dissipation capability of 300 mW. Key electrical characteristics include a DC current gain (hFE) minimum of 200 at 1 mA and 5 V, and a saturation voltage of 150 mV at 500 µA base current and 10 mA collector current. The component is AEC-Q100 qualified for automotive applications.

Feature Summary

• Dual NPN configuration with integrated 10 kΩ base resistors simplifies circuit design by reducing external component count.
• Automotive-grade qualification ensures reliability and compliance with stringent industry standards for vehicle electronics.
• Compact SOT-363 packaging enables efficient space utilization on high-density printed circuit boards.

Applications

• Switching circuits in automotive electronic control units
• General-purpose digital logic interfacing
• Low-power signal switching in industrial equipment

Procurement Notes

Verify the specific suffix ZLX against official Nexperia documentation to confirm package marking and tape-and-reel specifications. Ensure compatibility with standard reflow soldering profiles defined for the TSSOP6 form factor. Confirm RoHS3 compliance status through the manufacturer's latest environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN switch with fixed base resistance is required. The 10 kΩ internal resistor value suits moderate drive currents. Compare hFE and saturation voltage requirements against load conditions. Verify that the 50 V breakdown voltage exceeds the maximum circuit voltage under all operating scenarios.

Part Context

The PUMH4 series belongs to Nexperia's portfolio of resistor-equipped transistors designed to replace discrete resistor-transistor networks. This family offers consistent performance across automotive and industrial segments. The ZLX suffix typically denotes a specific packaging or marking variant within the broader PUMH4 product line, requiring verification against the master datasheet for precise identification.

Replacement Considerations

Publicly confirmed substitutes include PEMH4,115 for NPN/NPN configurations in similar packages. Cross-reference pinouts and electrical parameters carefully. Verify that alternative components meet the same AEC-Q100 automotive qualification if required for the application.
