MUN5214DW1T1G

Overview

The MUN5214DW1T1G is a dual NPN digital transistor manufactured by onsemi, housed in a surface-mount SOT-363 (SC-88) package with six terminals. It integrates two independent NPN transistors with built-in bias resistors to simplify circuit design. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 10 kOhms and a resistor ratio of 0.21. Minimum DC current gain (hFE) is specified at 80. Power dissipation is rated at 256 mW, with an operating temperature range spanning from -55°C to +150°C.

Feature Summary

• Integrates dual NPN transistors with internal biasing networks to reduce component count and board space.
• Designed for high-speed switching applications with simplified drive requirements.
• Operates within an extended industrial temperature range suitable for diverse environmental conditions.

Applications

• General-purpose switching circuits
• Driver stages for logic interfaces
• Level shifting between different voltage domains

Procurement Notes

Verify the complete part number including suffixes against official onsemi documentation to ensure correct packaging and variant selection. Confirm RoHS compliance status through manufacturer declarations. Cross-reference datasheet revisions to validate parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required in a compact SOT-363 footprint. Ensure the 50 V voltage rating and 100 mA current capacity meet the specific load requirements. Verify that the 10 kOhm input resistance aligns with the driving source capabilities.

Part Context

This component belongs to the MUN5214DW1 series of pre-biased transistors. It shares the same physical package and general topology as related variants like the MUN5212 and MUN5213, differing primarily in internal resistor values and gain characteristics. The series is designed to replace discrete resistor-transistor combinations.

Replacement Considerations

Direct substitutes within the same family include MUN5212DW1T1G and MUN5213DW1T1G, provided their specific resistor ratios and gain levels match the circuit requirements. Verify pin compatibility and thermal performance when considering alternative manufacturers' equivalents.
