MUN5233DW1T1

Overview

The MUN5233DW1T1 is a dual Bias Resistor Transistor (BRT) from onsemi, featuring two NPN silicon transistors integrated with monolithic bias resistor networks in an SOT-363 package. It replaces discrete components and external biasing resistors to simplify circuit design. Key electrical parameters include a maximum collector-emitter voltage of 50 Vdc, a continuous collector current of 100 mAdc, and a total device power dissipation of 187 mW at 25°C. The internal network consists of a series base resistor (R1) of 4.7 kOhms and a base-emitter resistor (R2) of 47 kOhms.

Feature Summary

• Integrates two NPN transistors with monolithic bias resistor networks into a single surface-mount device.
• Eliminates the need for individual external biasing resistors, reducing component count and board space.
• Designed for low-power applications where minimizing footprint is critical.

Applications

• Low-power surface mount applications requiring simplified circuit design.
• Circuit designs prioritizing reduced board space and component count.
• Digital switching circuits utilizing pre-biased transistor arrays.

Procurement Notes
