The STMicroelectronics SMA4F30AY is a unidirectional TVS diode designed for robust transient voltage suppression. Featuring a 30V reverse standoff voltage and a low 48.4V clamping voltage at a peak pulse current of 8.3A, this component offers significant protection. It demonstrates a peak pulse power rating of 400W and a wide operating temperature range of -55°C to 175°C. The device is qualified to AEC-Q101 standards, making it suitable for automotive applications. Supplied in a compact SMAflat (DO-221AC, SMA Flat Leads) package on tape and reel, the SMA4F30AY is engineered for surface mounting. This technology is commonly employed in automotive electronics, industrial control systems, and consumer electronics to safeguard sensitive circuitry from electrostatic discharge and other transient overvoltage events.
