STMicroelectronics SMA4F12A is a unidirectional TRANSIL™ TVS diode designed for robust transient voltage suppression. Featuring a 12V reverse standoff voltage, this device offers a 13.3V minimum breakdown voltage and a 25.3V maximum clamping voltage at a peak pulse current of 20.1A. The SMA4F series component delivers 400W of peak pulse power. Its SMAflat (DO-221AC, SMA Flat Leads) surface mount package is suitable for applications requiring efficient thermal management and minimal board space. Operating across an extended temperature range of -55°C to 175°C, the SMA4F12A is utilized in general purpose protection schemes across various industrial and consumer electronics sectors. The component is supplied in Tape & Reel (TR) packaging.
