MMUN2240LT1G

The MMUN2240LT1G is a digital transistor from On Semiconductor, part of the Bias Resistor Transistor (BRT) series. This device integrates a single transistor with a monolithic bias network, consisting of a series base resistor and a base-emitter resistor, simplifying circuit design and reducing board space. It is designed to replace a single device and its external resistor bias network.

Key electrical specifications include a maximum collector-emitter voltage of 50Vdc and a continuous collector current of 100mAdc. The transistor type is NPN with pre-bias, and it has a nominal base resistor value of 47 kΩ. The DC current gain (hFE) is a minimum of 120 at 5mA collector current and 10V Vce. The saturation voltage (Vce Sat) is a maximum of 250mV at 1mA base current and 10mA collector current. The maximum power dissipation is rated at 246mW at 25°C ambient temperature.

This transistor is supplied in a SOT-23-3 (TO-236) surface mount package. It is Pb-free and Halogen-free, complying with RoHS standards. The device is suitable for applications requiring simplified circuitry and reduced component count.
