PUMH9-QZ

Overview

The PUMH9-QZ is a dual NPN resistor-equipped transistor (RET) manufactured by Nexperia USA Inc. It integrates two NPN transistors with built-in bias resistors in a compact SOT363-3 (SC-88) surface-mount package. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Internal resistance values are specified as R1 = 10 kΩ and R2 = 47 kΩ. The component is qualified under the AEC-Q101 standard for automotive applications, ensuring reliability in demanding environments. Power dissipation is rated at 300 mW, making it suitable for space-constrained digital switching and logic interface circuits.

Feature Summary

• AEC-Q101 qualified for automotive electronic applications
• Integrated dual NPN configuration with fixed bias resistors
• Compact SOT363-3 surface-mount packaging

Applications

• Automotive digital switching circuits
• Logic level translation interfaces
• General-purpose amplification in constrained spaces

Procurement Notes

Verify the specific suffix 'QZ' against official Nexperia documentation to confirm exact tape-and-reel specifications and manufacturing origin. Ensure compliance with AEC-Q101 requirements if used in automotive designs. Cross-reference datasheet revision levels to confirm parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN pre-biased solution is required in an ultra-small footprint. The integrated resistors simplify circuit design by reducing external component count. Verify that the 10 kΩ base resistor value aligns with the target drive current and logic family voltage levels for proper saturation performance.

Part Context

The PUMH9-QZ belongs to Nexperia's Q-series of components designed specifically for automotive electronics. This series adheres to strict quality and reliability standards defined by AEC-Q101. The part serves as the NPN variant within a broader family that includes PNP/PNP (PUMB9-Q) and NPN/PNP (PUMD9-Q) complements, offering standardized solutions for differential or complementary switching needs.

Replacement Considerations

Direct functional substitutes include the PUMH9-Q and PUMH9,135. These parts share identical electrical characteristics and pinout configurations. Verify package compatibility and automotive qualification status when substituting non-Q series parts into existing designs.
