MUN5114DW1T1

Overview

The MUN5114DW1T1 is a dual Bias Resistor Transistor (BRT) from onsemi, featuring two PNP silicon transistors integrated with monolithic bias resistor networks in an SOT-363 package. It replaces discrete devices and external resistors to simplify circuit design. Key electrical parameters include a collector-emitter voltage of -50 Vdc, continuous collector current of -100 mAdc, and total device power dissipation of 250 mW at 25°C. The internal resistors are R1 = 10 kΩ and R2 = 47 kΩ. DC current gain is specified as a minimum of 80 at -5.0 mA collector current.

Feature Summary

• Integrates two PNP transistors with built-in series base and base-emitter resistors into a single surface-mount device.
• Reduces printed circuit board space and component count by eliminating the need for external biasing components.

Applications

• Low-power surface mount applications requiring compact transistor arrays.
• Circuit designs where board space is limited and simplified biasing is required.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm shipping format and compliance status. Confirm RoHS status and lead times directly with authorized distributors or the manufacturer before placing orders. Ensure the part number matches the exact configuration required for the application.

Selection Notes

Select this component when a dual PNP digital transistor with a 10 kΩ series base resistor and 47 kΩ base-emitter resistor is needed. Verify that the -50 V collector-emitter voltage and -100 mA current ratings meet the circuit requirements. Consider the SOT-363 package dimensions for PCB layout constraints.
