PUMH7HF

Overview

The PUMH7HF is a dual NPN pre-biased transistor array manufactured by Nexperia USA Inc. It integrates two NPN transistors with built-in bias resistors in a compact surface-mount package. The device features a collector-emitter voltage rating of 50V and a maximum continuous collector current of 100mA per element. Internal resistor values are specified as R1 (base) at 47 kΩ and R2 (emitter) at 22 kΩ. The component is designed for low-power switching applications, offering a maximum power dissipation of 300mW and a DC current gain (hFE) of at least 60 at 5mA and 5V. It is housed in a 6-TSSOP package.

Feature Summary

• Integrates dual NPN transistors with fixed internal bias resistors to simplify circuit design.
• Provides high-density packaging suitable for space-constrained surface-mount applications.
• Offers stable switching performance with defined saturation voltage characteristics.

Applications

• General-purpose switching circuits
• Driver stages for logic interfaces
• Level shifting applications

Procurement Notes

Verify the specific suffix 'HF' against the official Nexperia datasheet to confirm pinout compatibility and electrical tolerances. Ensure the ordering code matches the required tape-and-reel or cut-tape configuration. Confirm RoHS compliance status for the specific batch prior to integration into regulated assemblies.

Selection Notes

Select this component when dual NPN switching with integrated biasing is required in a small footprint. Compare the 47kΩ/22kΩ resistor ratio against alternative models if different base drive currents are needed. Verify that the 50V breakdown voltage meets the system's peak transient requirements.

Part Context

The PUMH7HF belongs to the PUMH series of pre-biased transistor arrays from Nexperia. This series consolidates discrete transistors and resistors into single packages to reduce board space and assembly costs. The 'PUMH' designation typically indicates NPN-NPN configurations with specific resistor values optimized for standard logic interface applications.

Replacement Considerations

Check for direct cross-reference part numbers from Nexperia or other manufacturers offering identical 50V, 100mA dual NPN pre-biased arrays in 6-TSSOP packages. Verify that substitute components maintain the same R1/R2 ratios and hFE minimums to ensure circuit functionality remains unchanged.
