PUMD3/ZL,165

Overview

The PUMD3/ZL,165 is a digital transistor array manufactured by Nexperia USA Inc., housed in a 6-TSSOP surface-mount package. It integrates one NPN and one PNP pre-biased bipolar junction transistor (BJT) within a single compact component. The device features a maximum collector-emitter voltage of 50V and a continuous collector current rating of 100mA. Internal base resistors are specified at 10 kΩ for both the NPN and PNP sections. The unit operates with a maximum power dissipation of 300mW and maintains a minimum DC current gain of 30 at 5mA and 5V conditions.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in biasing resistors to reduce external component count.
• Utilizes a low-profile 6-TSSOP surface-mount package suitable for space-constrained printed circuit board designs.
• Provides standardized internal resistance values to simplify driver interface circuits and ensure consistent switching performance.

Applications

• General-purpose signal switching and level shifting in consumer electronics.
• Driver interfaces for logic gates and microcontroller output expansion.
• Complementary switching stages in portable battery-powered devices.

Procurement Notes

Verify the specific suffix designation against official Nexperia documentation to confirm exact manufacturing lot specifications and regional compliance markings. Ensure that the ordering part number matches the required tape-and-reel quantity or cut-tape configuration for automated assembly processes. Cross-reference the datasheet revision history to confirm compatibility with current environmental regulations and material declarations before finalizing procurement orders.

Selection Notes

Select this component when a matched pair of NPN and PNP switches is required in a minimal footprint application. The integrated 10 kΩ base resistors eliminate the need for external biasing components, simplifying schematic design. Verify that the 50V voltage rating and 100mA current capacity align with the target circuit requirements. Consider the thermal limitations imposed by the 300mW power dissipation rating under expected operating conditions.

Part Context

This part belongs to the PUMD3 family of dual pre-biased transistors from Nexperia. The ZL suffix typically denotes specific packaging or reel configuration details rather than altering the fundamental electrical characteristics of the semiconductor die. It serves as a direct replacement for discrete resistor-transistor networks in legacy designs requiring complementary switching capabilities.

Replacement Considerations

Direct substitutes include other Nexperia dual pre-biased transistors in the SOT-363 package such as the PUMD2 or PUMD4 series, provided the polarity configurations match the circuit requirements. Verify pinout compatibility and internal resistor values when considering cross-brand alternatives to ensure functional equivalence without redesigning the surrounding circuitry.
