STMicroelectronics SMA4F31A is a unidirectional TVS diode from the SMA4F, TRANSIL™ series, designed for robust transient voltage suppression. This component offers a 31V reverse standoff voltage and a 34.2V minimum breakdown voltage, ensuring effective protection against voltage spikes. With a 65V maximum clamping voltage at 8A peak pulse current (Ipp), it provides a 400W peak pulse power dissipation. The device is housed in a space-saving SMAflat (DO-221AC, SMA Flat Leads) surface mount package, suitable for automated assembly. Its wide operating temperature range of -55°C to 175°C makes it reliable in demanding environments. Applications include general purpose protection in automotive, industrial, and consumer electronics sectors. The component is supplied in tape and reel packaging.
