Overview
The onsemi MUN2215T1 is an NPN silicon Bias Resistor Transistor (BRT) housed in the SC-59 surface-mount package. It integrates a single transistor with a monolithic bias network consisting of a series base resistor and an open base-emitter connection. The device supports a maximum collector current of 100 mA and withstands collector-emitter voltages up to 50 Vdc. Electrical characteristics include a minimum DC current gain of 160, a typical input resistance of 10 kOhms, and a power dissipation rating of 230 mW at 25°C. The component operates within a temperature range of -55°C to +150°C.
Feature Summary
- Integrates a single NPN transistor with a monolithic bias network containing a series base resistor and an open base-emitter path.
- Designed to replace discrete devices and external resistor networks, reducing board space and component count.
- Features modified gull-wing leads in the SC-59 package to absorb thermal stress during wave or reflow soldering.
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 against official documentation to confirm package type and environmental compliance. Confirm that the SC-59 package variant matches the required footprint for the target PCB layout. Ensure the manufacturer designation aligns with the intended supply chain requirements before finalizing procurement orders.
Selection Notes
Select this component when a high-gain NPN switch with a fixed 10 kOhm base input is required without an emitter resistor. Verify that the 100 mA continuous collector current meets the load requirements. Ensure the design accommodates the specific thermal dissipation limits associated with the SC-59 package dimensions.
Part Context
This part belongs to the MUN2211T1 Series of preferred NPN Silicon Surface Mount Transistors with Monolithic Bias Resistor Networks. The series provides various resistor combinations to simplify circuit design across different logic families and voltage levels.
Replacement Considerations
MUN2215T1G serves as the lead-free equivalent within the same series. Cross-reference with other BRTs offering identical 10 kOhm input resistance and 50V ratings if pinout compatibility must be maintained.
