UMC5NQ-7

Overview

The UMC5NQ-7 is a dual complementary pre-biased transistor array from Diodes Incorporated, featuring one NPN and one PNP bipolar junction transistor within an SOT-353 surface-mount package. It integrates internal base resistors (R1: 47 kΩ for NPN, 4.7 kΩ for PNP) to simplify circuit design. The device supports a maximum collector current of 100 mA and operates up to a transition frequency of 250 MHz. Qualified to AEC-Q101 standards, it functions across a temperature range of -55°C to +150°C with a power dissipation rating of 290 mW.

Feature Summary

• Dual complementary configuration integrating one NPN and one PNP pre-biased transistor in a single ultra-small surface mount package.
• Internal biasing network simplifies circuit design by reducing external component count and board space requirements.
• Qualified to AEC-Q101 automotive standards and capable of PPAP submission for high-reliability applications.
• Totally lead-free and fully RoHS compliant, manufactured using halogen and antimony-free green molding compounds.

Applications

• Automotive electronic systems requiring AEC-Q101 qualified components
• General-purpose switching circuits utilizing complementary logic levels
• Driver stages for low-power loads where board space is constrained

Procurement Notes

Verify the specific ordering suffix matches the required reel size and quantity per reel. Confirm that the marking code corresponds to the intended production date code. Ensure compliance with RoHS 2 and REACH directives if applicable to the target market. Check for PPAP capability requirements if sourcing for automotive assembly lines.

Selection Notes

Select this component when a complementary pair of pre-biased transistors is needed in a minimal footprint. Verify that the integrated resistor values (47 kΩ and 4.7 kΩ) align with the input drive requirements. Ensure the operating voltage and current limits accommodate the specific load conditions without exceeding the 290 mW power dissipation rating.

Part Context

This part belongs to the UMC5 series of dual complementary pre-biased transistors produced by Diodes Incorporated. It utilizes the SOT-353 case style, which is standardized for small surface-mount applications. The product line is designed to replace discrete resistor-transistor combinations in digital logic interfaces.

Replacement Considerations

Direct substitutes must match the SOT-353 package and contain both NPN and PNP pre-biased elements. Verify that any alternative part meets the same AEC-Q101 qualification level and maintains comparable electrical characteristics for transition frequency and saturation voltage.
