MUN5212DW1T1G

Overview

The MUN5212DW1T1G is a dual NPN digital transistor manufactured by onsemi, housed in a SOT-363 (SC-88) surface-mount package with six pins. It integrates two isolated NPN transistors with built-in bias resistors, featuring a typical input resistance of 22 kOhms and a resistor ratio of 1. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current of 100 mA, and a power dissipation of 187 mW. The device operates within a temperature range of -55°C to +150°C and guarantees a minimum DC current gain (hFE) of 60.

Feature Summary

• Integrates dual NPN transistors with built-in bias resistors to replace discrete components and external resistor networks.
• Provides a compact surface-mount solution in a six-pin SOT-363 package for space-constrained designs.
• Offers high current gain and low saturation voltage for efficient switching applications.

Applications

• General-purpose switching circuits
• Driver stages for relays and solenoids
• Logic level shifting and buffer interfaces

Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives and check for automotive qualification status if required for the target application environment.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is needed to simplify schematic design and reduce board space. Compare the 22 kOhm base resistance and 50 V voltage rating against circuit requirements to ensure adequate drive capability and voltage headroom.

Part Context

This part belongs to the MUN5212DW1 series of pre-biased transistors from onsemi. It shares the SOT-363 footprint with other variants in the family but differs in internal resistor values and transistor characteristics. It serves as a direct replacement for similar dual NPN BRTs from other manufacturers offering equivalent pinouts and electrical ratings.

Replacement Considerations

Verify pinout compatibility and electrical limits before substituting with parts like SMBT3904DW1T1G or SMUN5213DW1T1G. Confirm that alternative devices meet the 50 V VCEO and 100 mA IC requirements while maintaining the dual NPN configuration.
