STMicroelectronics SMA4F18AY is a unidirectional TVS diode designed for robust transient voltage suppression. This component, part of the SMA4F series, offers an 18V reverse standoff voltage and a 29.2V maximum clamping voltage at a peak pulse current (Ipp) of 13.7A, corresponding to 400W peak pulse power. Its surface mount SMAflat package (DO-221AC) facilitates integration into compact designs, operating across a wide temperature range from -55°C to 175°C. Qualified to AEC-Q101 standards for automotive applications, this device is suitable for protecting sensitive circuitry against voltage surges in automotive and industrial environments.
