PUMH10-QX

Overview

The Nexperia PUMH10-QX is an NPN/NPN Resistor-Equipped Transistor (RET) housed in a TSSOP6 (SOT363-3) surface-mount package. It integrates two NPN transistors with built-in bias resistors, specifically R1 at 2.2 kΩ and R2 at 47 kΩ per transistor. The device supports a collector-emitter voltage of 50 V and an output current of 100 mA per transistor. Total power dissipation is rated at 300 mW at 25 °C ambient temperature. It is qualified according to AEC-Q101 standards for automotive applications.

Feature Summary

• Integrates dual NPN transistors with fixed internal bias resistors to simplify circuit design.
• AEC-Q101 qualified for reliability in automotive environments.
• Compact SOT363-3 package reduces component count and pick-and-place costs.

Applications

• Low current peripheral driver
• Control of IC inputs
• Replacement for general-purpose transistors in digital applications

Procurement Notes

Verify the specific suffix 'QX' against the manufacturer's official ordering information to confirm packaging details such as reel size or tape width. Ensure the procurement source provides the complete part number including the '-Q' designation to guarantee AEC-Q101 qualification status. Cross-reference the marking code H%0 with manufacturing site codes if traceability is required for production integration.

Selection Notes

Select this component when designing circuits requiring dual NPN switching with integrated base biasing. The built-in resistors eliminate external components, reducing board space. Verify that the required input impedance matches the 2.2 kΩ R1 value. Ensure the application current does not exceed 100 mA per transistor and that the total power dissipation remains within the 300 mW limit under expected thermal conditions.

Part Context

The PUMH10-Q belongs to Nexperia's family of resistor-equipped double transistors (RETs). It serves as the NPN/NPN variant, complemented by the PNP/PNP PUMB10-Q and NPN/PNP PUMD10-Q. These devices are designed to replace multiple discrete components in digital logic and interface circuits, offering a standardized solution for signal conditioning and level shifting in compact electronic assemblies.

Replacement Considerations

Direct functional equivalents include the PUMB10-Q (PNP/PNP) and PUMD10-Q (NPN/PNP) from the same series. For pin-compatible replacements, verify the complementary transistor types match the circuit requirements. Ensure any substitute maintains the AEC-Q101 qualification if used in automotive contexts.
