SMMUN2211LT1G Description

Short technical summary and product information.

The SMMUN2211LT1G is a single, pre-biased NPN bipolar junction transistor (BJT) manufactured by ON Semiconductor. This device integrates a transistor with a monolithic bias resistor network, simplifying circuit design and reducing component count and board space. It features a maximum collector-emitter voltage (VCEO) of 50V and a continuous collector current (IC) of 100mA.

 

The transistor is housed in a surface-mount SOT-23-3 package. Key electrical characteristics include a typical DC current gain (hFE) of 35 at 5mA collector current and 10V Vce, and a maximum Vce saturation of 250mV at 300µA base current and 10mA collector current. The internal bias network includes resistors with nominal values of 10 kΩ for both the series base resistor (R1) and the base-emitter resistor (R2).

 

This series of digital transistors is designed to replace individual transistors and their external bias resistors. The device is Pb-free and halogen-free, complying with RoHS standards. Its integrated design makes it suitable for applications where space and component count reduction are critical.
