This quad monolithic silicon voltage suppressor from On Semiconductor, part number MMQA18VT1G, is designed for applications requiring transient overvoltage protection. It is intended for use in voltage and ESD sensitive equipment such as computers, printers, business machines, communication systems, and medical equipment.
The device utilizes a common anode design, protecting four separate lines with a single SC-74 package, making it ideal for space-constrained applications. Key electrical specifications include a nominal standoff voltage of 14V and a clamping voltage of 26V at a peak pulse current of 923mA (8/20µs waveform).
It offers a peak power dissipation of 24W at 1.0 ms and 150W at 20/109s. The operating temperature range is -55°C to 150°C. The MMQA18VT1G is supplied in an SC-74, SOT-457 surface mount package.
Environmental compliance includes Pb-Free status, verified by the datasheet. The device also has an ESD rating of Class 3B, exceeding 16 kV per the Human Body Model.
