MUN5236T1

Overview

The onsemi MUN5236T1 is an NPN 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 collector-emitter voltage rating of 50 Vdc, a continuous collector current of 100 mAdc, and a total power dissipation of 202 mW at 25°C. Typical internal resistance values are 100 kOhms for both R1 and R2, yielding a ratio of 1. The minimum DC current gain (hFE) is specified as 80.

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 logic circuits and higher voltage loads
• 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 status. Confirm that the requested part number matches the exact electrical characteristics required for the design. Ensure compatibility with standard SMD assembly processes such as wave or reflow soldering.

Selection Notes

Select this component when circuit design requires simplification through integrated biasing. The fixed 100 kOhm resistor values suit applications needing moderate input impedance. Verify that the 50V voltage rating and 100mA current capacity align with the target load requirements.

Part Context

This device belongs to the MUN5211T1 Series of digital transistors manufactured by onsemi. The series is engineered to consolidate discrete transistor and resistor networks into a single surface-mount package. This integration supports cost reduction and space optimization in electronic designs.

Replacement Considerations

MUN5236T1G serves as the lead-free equivalent within the same series.
