MUN5234T1

Overview

The onsemi MUN5234T1 is an NPN Bias Resistor Transistor (BRT) housed in a SC-70/SOT-323 package. It integrates a single transistor with a monolithic bias network consisting of a series base resistor and a base-emitter resistor. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 Vdc, a continuous collector current (IC) of 100 mAdc, and a total device power dissipation (PD) of 202 mW at 25°C. The internal resistors are R1 = 22 kOhms and R2 = 47 kOhms.

Feature Summary

Integrates a single NPN transistor with a monolithic bias resistor network to replace discrete components
Reduces board space and component count by eliminating external biasing 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 applications

Procurement Notes

Verify the specific ordering suffix when purchasing. The provided datasheet lists the MUN5234T1G variant as Pb-Free. Confirm whether the exact part number requested includes the G suffix for lead-free compliance or if it refers to the standard version. Ensure the supplier documentation matches the required environmental specifications.

Selection Notes

Select this component when a compact NPN digital transistor solution is required for low-power surface mount designs. The integrated 22k/47k resistor network simplifies circuit design compared to using discrete transistors and resistors. Verify that the 50V collector-emitter voltage rating meets the system requirements.

Part Context

This component belongs to the MUN5211T1 Series of NPN Silicon Surface Mount Transistors with Monolithic Bias Resistor Networks. The series is designed to simplify circuit design by integrating bias resistors directly with the transistor die, offering a space-saving alternative to traditional discrete bias networks.
