PUMD6H-QF

Overview

The PUMD6H-QF is a dual NPN pre-biased transistor in a SOT323 (SC-70) surface-mount package. It integrates two NPN transistors with built-in base resistors, eliminating the need for external components and reducing printed circuit board area. The device features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 100 mA. Internal biasing resistors are typically configured to provide a base-to-emitter resistance ratio that facilitates direct logic interface compatibility. The component operates within a junction temperature range of -55 °C to +150 °C and is qualified to AEC-Q101 standards for automotive reliability.

Procurement Notes

Verify the specific ordering code suffix to confirm the exact resistor values and tolerance specifications required for the design. Confirm compliance with RoHS and REACH regulations through official Nexperia documentation before finalizing procurement. Ensure the selected package orientation matches the PCB footprint guidelines provided in the datasheet.

Selection Notes

Select this component when space constraints require integrated biasing solutions for dual NPN switching tasks. Verify that the internal base resistor values align with the driving logic voltage levels to ensure proper saturation. Consider the thermal dissipation capabilities of the SOT323 package relative to the expected duty cycle and ambient temperature conditions.

Part Context

This part belongs to Nexperia's portfolio of pre-biased transistors designed to simplify circuit design by combining multiple discrete functions into single packages. The PUMD series specifically targets applications requiring compact, reliable switching elements with reduced bill-of-materials complexity. These devices are widely utilized in consumer electronics and automotive modules where board real estate is limited.

Replacement Considerations

Direct replacements must match the SOT323 package, dual NPN topology, and 50V/100A ratings. Verify equivalent internal resistor values to maintain signal integrity. Cross-reference with other manufacturers' SC-70 dual NPN pre-biased transistors ensuring identical pinout and electrical characteristics.
