MUN5213T1

Overview

The onsemi MUN5213T1 is an NPN Silicon Bias Resistor Transistor (BRT) housed in the SC-70/SOT-323 package. It integrates a single transistor with a monolithic bias network consisting of two resistors: a series base resistor and a base-emitter resistor. The device features a maximum collector current of 100 mAdc, a collector-base voltage of 50 Vdc, and a collector-emitter voltage of 50 Vdc. Total device dissipation is rated at 202 mW at 25°C ambient temperature. The internal resistors are both 47 kOhms, providing a typical input resistance of 47 kOhms.

Feature Summary

• Integrates a single NPN transistor with a monolithic bias network to replace discrete components
• Reduces board space and component count by eliminating external bias resistors
• SC-70/SOT-323 package designed for low power surface mount applications

Applications

• Level shifting between 12 or 24 Volt 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 requested part number matches the exact electrical characteristics required for the design. Ensure compatibility with standard wave or reflow soldering processes specified for the SC-70/SOT-323 package.

Selection Notes

Select this component when a compact NPN digital transistor solution is needed with a 47 kOhm base-to-base and base-to-emitter resistor configuration. Verify that the 50 Vdc voltage rating and 100 mA current capacity meet the circuit requirements. Consider the thermal dissipation limits relative to the expected operating ambient temperature.

Part Context

This device belongs to the MUN5211T1 Series of preferred devices from onsemi. The series includes various BRT configurations with different resistor values to suit diverse circuit needs while maintaining the same physical footprint and general electrical ratings.
