MUN5311DW1T1G

Overview

The MUN5311DW1T1G is a dual digital transistor from onsemi, integrating an NPN and a PNP Bias Resistor Transistor (BRT) within a single SOT-363 package. It features a monolithic bias network with typical input resistors of 10 kOhms and a resistor ratio of 1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 35 and a power dissipation rating of 187 mW. It operates across a temperature range of -55°C to +150°C and is AEC-Q100 qualified for automotive applications.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in bias resistors to simplify circuit design.
• Reduces printed circuit board space requirements by replacing discrete components with a single surface-mount device.
• AEC-Q100 qualified for robust performance in automotive environments.

Applications

• Automotive electronic systems requiring qualified semiconductor components
• Low-power surface mount applications where board space is limited
• General-purpose switching circuits utilizing integrated bias networks

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct packaging and qualification status. Confirm that the component meets all required environmental standards, such as RoHS compliance, prior to integration into final assemblies. Cross-reference datasheet revisions to ensure compatibility with existing design specifications.

Selection Notes

Select this component when a compact solution for both NPN and PNP switching is required. The 10 kOhm input resistance suits standard logic interface levels. Ensure the thermal management strategy accounts for the 187 mW power dissipation limit in the SOT-363 package under expected operating conditions.
