MUN2214T3G

Overview

The MUN2214T3G is an NPN Digital Transistor (BRT) manufactured by onsemi, designed to replace a single device and its external resistor bias network. It integrates a single transistor with a monolithic bias network consisting of a series base resistor and a base-emitter resistor. Key electrical parameters include a maximum collector current (IC) of 0.1 A, a collector-emitter voltage (VCEO) of 50 V, and a minimum DC current gain (hFE) of 80. The built-in bias resistor ratio is specified as 4.7, with typical values of R1 = 10 kΩ and R2 = 47 kΩ. The component is housed in a SC-59 package (R-PDSO-G3) with three pins.

Feature Summary

• Integrates a single NPN transistor with a monolithic bias network comprising two resistors to eliminate individual external components.
• Simplifies circuit design by reducing board space and component count compared to discrete solutions.
• Compliant with RoHS standards and is lead-free.

Applications

• General-purpose switching applications requiring simplified bias networks.
• Replacement for discrete transistor and resistor combinations in digital logic circuits.
• Applications where reduced board space and lower system cost are critical.

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging configuration matches the production requirements. Confirm that the component meets all necessary environmental compliance standards for the intended application region. Cross-reference the manufacturer part number with official distributor catalogs to ensure authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required. Ensure the 50 V collector-emitter voltage and 100 mA collector current ratings exceed the maximum operational limits of the target circuit. Verify that the internal resistor ratio aligns with the desired input impedance and drive characteristics for the specific interface being designed.

Part Context

The MUN2214T3G belongs to the MUN2214 series of Digital Transistors from onsemi. This series is engineered to simplify circuit designs by integrating bias resistors directly onto the silicon die. It serves as a direct replacement for various other manufacturers' BRT parts with similar electrical characteristics and pin configurations, facilitating easier sourcing and design standardization across different platforms.

Replacement Considerations

Potential substitutes include the MMUN2214LT1G and other NPN BRTs with identical 10k/47k resistor ratios and SC-59 packaging. Verify pinout compatibility and thermal performance before substitution.
