MUN5211DW1T1G

Overview

The MUN5211DW1T1G is a dual NPN digital transistor manufactured by onsemi, housed in a surface-mount SOT-363 (SC-88) package with six pins. It integrates two isolated NPN transistors with built-in bias resistors to simplify circuit design. Key electrical parameters include a maximum DC collector current of 100 mA and a collector-emitter voltage rating of 50 V DC. The device features a minimum DC current gain (hFE) of 160 and operates within a temperature range of -55°C to +150°C. Power dissipation is rated at 385 mW, with a typical input resistance configuration supporting efficient switching applications.

Feature Summary

• Integrates dual NPN transistors with pre-biased resistors to replace discrete components
• Provides high current gain for effective signal switching and logic interfacing
• Designed for surface-mount assembly in compact electronic layouts

Applications

• Logic level shifting and interface circuits
• Switching applications in consumer electronics
• Driver circuits for low-power loads

Procurement Notes

Verify the specific ordering suffix and tape-and-reel quantity against official distributor catalogs before purchase. Confirm that the component meets required automotive or industrial qualification standards if applicable to the end application. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet to prevent package damage during soldering processes.

Selection Notes

Select this component when space constraints require integrating both transistor and bias resistor functions into a single package. Compare input resistance values with other MUN52xx series variants to match specific drive requirements. Ensure the 50V voltage rating and 100mA current capacity exceed the maximum operational stresses of the target circuit design.

Part Context

This part belongs to the MUN5211DW1 series of pre-biased bipolar junction transistors. It is designed as a compact alternative to discrete resistor-transistor networks, reducing board space and assembly complexity. The SOT-363 package allows for high-density mounting in portable devices and modern consumer electronics where minimal footprint is critical.

Replacement Considerations

Direct substitutes include other MUN5211DW1 variants from onsemi or equivalent dual NPN digital transistors from manufacturers like NXP or Rohm, provided pinouts and electrical ratings match.
