The STMicroelectronics SMA4F22A is a TRANSIL™ TVS diode designed for robust transient voltage suppression. This surface mount component, housed in a SMAflat package (DO-221AC), offers a reverse standoff voltage of 22V and a breakdown voltage of 24.4V minimum. It provides a maximum clamping voltage of 48.3V at a peak pulse current of 11.2A, with a peak pulse power rating of 400W. Operating across a wide temperature range from -55°C to 175°C, this unidirectional device is suitable for general-purpose applications, including automotive and industrial electronics, where protection against voltage transients is critical. The component is supplied in Tape & Reel packaging.
