MUN2240T1

Overview

The MUN2240T1 is an NPN Silicon Bias Resistor Transistor (BRT) from the MUN2211T1 Series, manufactured by onsemi. It integrates a single transistor with a monolithic bias network consisting of a series base resistor and an open base-emitter connection within a surface-mount SC-59 package. The device features a collector-base voltage of 50 Vdc and a collector current rating of 100 mAdc. Electrical characteristics include a DC current gain ranging from 80 to 140 at VCE = 10 V and IC = 5.0 mA. The internal series base resistor (R1) has a nominal value of 47 kΩ, while the base-emitter resistor (R2) is open circuit. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

Integrates a single NPN transistor with a monolithic bias network to replace discrete components
Features an open base-emitter configuration for specific logic interface applications
Designed for low power surface mount applications using the SC-59 package

Applications

Level shifting between different voltage logic domains
Open collector inverter circuits for signal inversion
Unregulated current source implementations

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to confirm packaging specifications and compliance status. Confirm that the SC-59 package variant matches the required footprint for the target PCB design. Ensure that the Pb-Free designation aligns with environmental regulations applicable to the final assembly process.

Selection Notes

Select this component when a high input impedance is required due to the absence of a base-emitter resistor. Verify that the 47 kΩ series base resistor provides adequate drive current for the intended load. Ensure the operating voltage does not exceed the 50 Vdc breakdown limits specified for the collector-base and collector-emitter junctions.

Part Context

This component belongs to the MUN2211T1 Series of NPN Silicon Bias Resistor Transistors. These devices are engineered to simplify circuit design by consolidating a transistor and its external biasing resistors into a single surface-mount unit. The series offers various resistor combinations to accommodate different logic families and drive requirements.
