The STMicroelectronics SMA4F30A is a TVS (Transient Voltage Suppressor) Diode from the SMA4F Transil series, engineered to safeguard sensitive electronic circuits from transient surges. Utilizing planar technology, this diode is suitable for high-end applications requiring low leakage current and high junction temperature stability for long-term reliability.
Key electrical characteristics include a peak pulse power dissipation of 400 W (10/1000 µs) and 2.5 kW (8/20 µs). It features a stand-off voltage range from 5 V to 188 V, with this specific part, the SMA4F30A, having a nominal stand-off voltage of 30V and a clamping voltage of 64.3V at 8.3A. The operating junction temperature range is -55°C to 175°C, ensuring robust performance under various thermal conditions.
This device is designed for unidirectional operation and comes in a surface-mount DO-221AC, SMA Flat Leads package, also known as SMAflat. The lead finishing is matte tin plating. It complies with standards such as UL94 V0 and IEC 61000-4-2, offering protection against electrostatic discharge up to 25 kV contact and 30 kV air discharge.
