Overview
The MUN2215T1G is a single NPN Digital Transistor (BRT) from onsemi, designed to replace discrete transistor and resistor networks. It integrates a monolithic bias network consisting of a series base resistor and a base-emitter resistor within an SOT-23 package. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 Vdc, a continuous collector current (IC) of 100 mA, and a typical input resistance of 10 kOhms. The device features a minimum DC current gain (hFE) of 60 at IC=10mA, VCE=10V, and operates within a temperature range of -55°C to +150°C.
Feature Summary
- Integrates a single NPN transistor with a monolithic bias resistor network to simplify circuit design.
- Reduces board space and component count by eliminating external biasing resistors.
- Provides high DC current gain for efficient switching applications.
Applications
- General-purpose switching circuits
- Driver circuits for relays and solenoids
- Logic level translation
Procurement Notes
Verify the specific suffix 'T1G' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target application. Cross-reference with authorized distributors to confirm availability and authenticity.
Selection Notes
Select this component when a compact solution for driving loads or interfacing logic levels is required. The integrated 10k Ohm base resistor simplifies drive requirements compared to discrete setups. Consider thermal dissipation limits in high-density PCB layouts due to the small SOT-23 footprint.
Part Context
This component belongs to the MUN22xx series of Bias Resistor Transistors (BRTs). These devices are engineered to streamline digital switching designs by combining active and passive elements into a single surface-mount package, offering a cost-effective alternative to traditional discrete resistor-transistor combinations.
Replacement Considerations
Compatible substitutes include other NPN BRTs with similar 50V/100mA ratings and 10k Ohm input resistance, such as the MMUN2215LT1G or NSVMUN2215LT1G. Verify pin compatibility and electrical tolerances before substitution.
