MUN5213DW1T1

Overview

The onsemi MUN5213DW1T1 is a dual Bias Resistor Transistor (BRT) housed in an SOT-363 package. It integrates two NPN silicon transistors with monolithic bias networks, each comprising a series base resistor and a base-emitter resistor. Key electrical parameters include a collector-base voltage of 50 Vdc, a collector-emitter voltage of 50 Vdc, and a maximum collector current of 100 mAdc. The device features a typical input resistance of 47 kOhms for both resistors. Thermal characteristics specify a total device dissipation of 187 mW when one junction is heated and 250 mW when both are heated at 25°C ambient temperature.

Feature Summary

• Integrates two NPN transistors with monolithic bias networks to replace discrete devices and external resistor biasing.
• Designed for low power surface mount applications where board space is limited.

Applications

• Low power surface mount circuit designs requiring simplified biasing.
• Applications prioritizing reduced component count and minimized board space.

Procurement Notes
