Overview
The MUN2213T1 is an NPN Bias Resistor Transistor (BRT) from onsemi, designed to replace a single device and its external resistor bias network. It integrates a monolithic bias network consisting of two resistors: a series base resistor (R1) and a base-emitter resistor (R2). Both resistors are nominally 47 kOhms. The device features a maximum collector current of 100 mA and a collector-emitter voltage rating of 50 Vdc. It is housed in the SC-59 surface mount package with a total power dissipation of 230 mW at 25°C ambient temperature.
Feature Summary
- Integrates a monolithic bias network with a series base resistor and a base-emitter resistor to eliminate external components.
- Designed for low power surface mount applications using the SC-59 package.
- Supports wave or reflow soldering processes.
Applications
- Level shifting between 12V/24V circuits and logic levels
- Open collector inverter configurations
- Unregulated current source implementations
Procurement Notes
Verify the specific ordering suffix when purchasing. The 'T1' suffix indicates tape and reel packaging containing 3000 units. Confirm RoHS compliance status by checking for the 'G' suffix if lead-free packages are required for the assembly process.
Selection Notes
Select this component when a fixed 47k/47k resistor ratio is appropriate for the biasing requirements. Ensure the application operates within the 50V collector-emitter voltage limit and 100mA continuous current constraints. Verify thermal management capabilities given the 230mW power dissipation rating in the SC-59 package.
Part Context
This part belongs to the MUN2211T1 Series of NPN Silicon Surface Mount Transistors with Monolithic Bias Resistor Networks. The series includes various models differentiated by their internal resistor values, allowing designers to choose specific bias ratios without adding discrete components to the circuit board.
Replacement Considerations
MUN2213T1G serves as the lead-free equivalent within the same series. Cross-reference with other BRT manufacturers such as NXP or Rohm, ensuring matching R1/R2 values and hFE characteristics for direct substitution.
