UMC5N-7

Overview

The UMC5N-7 is a dual complementary pre-biased transistor array manufactured by Diodes Incorporated, housed in an SOT353 surface-mount package. It integrates one NPN and one PNP bipolar junction transistor with internal biasing resistors to simplify circuit design. The NPN transistor (Q1) features a maximum collector current of 100 mA, a supply voltage rating of 50 V, and a typical input resistance of 47 kΩ. The PNP transistor (Q2) also supports a 100 mA collector current with a -50 V supply rating and a typical input resistance of 4.7 kΩ. Both transistors exhibit a gain-bandwidth product of 250 MHz and a maximum power dissipation of 150 mW at 25°C ambient temperature.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in biasing resistors to reduce component count and board space.
• Utilizes epitaxial planar die construction for reliable performance in automated assembly processes.
• Complies with AEC-Q101 standards to ensure high reliability suitable for automotive applications.

Applications

• Automotive electronic systems requiring high-reliability switching components.
• General-purpose digital logic interface circuits where board space is limited.
• Driver stages for low-power loads utilizing complementary output configurations.

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details, as standard quantities may vary. Confirm RoHS compliance status and halogen-free classification requirements prior to procurement. Ensure that the selected variant matches the required thermal and electrical specifications for the intended operating environment.

Selection Notes

Select this component when a compact solution for complementary switching is required within a single package. Evaluate the 150 mW power dissipation limit relative to the expected thermal conditions on the PCB. Consider the 47 kΩ and 4.7 kΩ base resistor values to determine compatibility with the driving logic levels and required switching speeds.

Part Context

This device belongs to the UMC5 series of dual complementary pre-biased transistors produced by Diodes Incorporated. The series is designed to replace multiple discrete components, offering a simplified alternative for designs needing both NPN and PNP switching capabilities in a minimal footprint.

Replacement Considerations

Check for direct equivalents such as the UMC5NQ-7 or UMC5NTR from other manufacturers if pinout and electrical parameters match. Verify that any substitute maintains the same SOT353 package dimensions and AEC-Q101 qualification if automotive reliability is required.
