SI-8120S Description

Short technical summary and product information.

The Sanken SI-8120S is a DC-DC switching regulator designed for step-down (buck) conversion applications. It features a fixed 12V output voltage and can supply up to 3A of current. The device accepts an input voltage range from 15V to 40V, making it suitable for various power supply designs.

 

With a switching frequency of 60kHz and a non-synchronous rectifier topology, the SI-8120S is designed for efficiency and reliability. It operates within a wide temperature range of -30°C to 125°C (TJ), ensuring performance in demanding environments. The regulator is housed in a TO-220F-5 package, suitable for through-hole mounting.

 

This component is part of the broader category of Power Management Integrated Circuits (PMICs) and specifically falls under Voltage Regulators. Its fixed output and robust operating parameters make it a practical choice for applications requiring a stable, regulated voltage from a higher input source.
