SMUN5111DW1T1G

Overview

The SMUN5111DW1T1G is a digital transistor from onsemi, featuring an NPN transistor integrated with a built-in bias resistor network. It is housed in a compact SOT-363 (SC-88) surface-mount package with six terminals. The device supports a maximum collector-emitter voltage of 50 V and a continuous DC collector current of 100 mA. It includes a typical input resistance of 10 kΩ and a standard resistor ratio of 1:2. The component operates within a temperature range of -55°C to +150°C and has a power dissipation rating of 250 mW. It is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Integrates an NPN bipolar junction transistor with a dual-resistor bias network to simplify circuit design.
• Utilizes a small SOT-363 surface-mount footprint to maximize board space efficiency.
• Engineered for high thermal stability with an extended operating temperature range up to 150°C.
• Meets AEC-Q100 qualification requirements for robust performance in automotive environments.

Applications

• Automotive electronic systems requiring qualified digital switching components.
• General-purpose logic level shifting and interface circuits.
• High-density printed circuit board layouts where space conservation is critical.

Procurement Notes

Verify the specific ordering suffix DW1T1G to ensure correct packaging and tape-and-reel specifications. Confirm that the AEC-Q100 qualification aligns with target application reliability standards. Check manufacturer documentation for updated moisture sensitivity levels and handling precautions during assembly processes.

Selection Notes

Select this component when a pre-biased NPN solution is required to reduce external passive component count. Ensure the 10 kΩ input resistance matches the driving source impedance requirements. Verify that the 50 V collector-emitter voltage rating exceeds the maximum circuit operating voltage under all conditions.

Part Context

This part belongs to the MUN5111 series of digital transistors manufactured by onsemi. It shares the same internal schematic as the non-automotive grade MUN5111DW1T1G but carries additional automotive qualification certifications. The SOT-363 package is common across various dual-transistor arrays in this product family.

Replacement Considerations

Direct functional substitutes include the MUN5111DW1T1G for non-automotive contexts. Cross-brand equivalents in the SOT-363 package with identical NPN+Resistor configurations should be evaluated for pin compatibility and electrical parameter matching.
