STMicroelectronics 1-Element Uni-Directional TVS Diode 2-Pin SMA Flat Package 400 W SMA4F10A

STMicroelectronics SMA4F10A 1-Element Uni-Directional TVS Diode in a 2-pin SMA flat package delivers high-performance transient voltage suppression with a peak pulse power rating of 400 W (10/1000 μs) and enhanced capability of 2.5 kW (8/20 μs). Designed specifically to protect sensitive electronic circuits from voltage spikes and surges, this TVS diode is suitable for industrial, automotive, power supply, and consumer electronic applications.

The diode features a unidirectional configuration with a low leakage current of 0.2 μA at 25°C, ensuring efficient standby operation with negligible power drain. Its compact, flat SMA package measures 4.6 mm by 2.9 mm with a height of only 1.05 mm, enabling easy integration onto surface-mounted circuit boards. The device is built with matte tin plated leads to optimize solderability and reliability in manufacturing.

Reliable operation is assured across a wide temperature range from -55°C to 175°C, with the diode maintaining high power capability at junction temperature maximums. With a maximum reverse stand-off voltage of 10 V and a breakdown voltage of 11.1 V, it effectively clamps voltage surges to protect downstream components. The maximum peak pulse current of 106 A provides strong protection against electrostatic discharge (ESD) events, making this diode suitable for demanding environments.

Key features include robust surge protection, low leakage, and compact design, making it ideal for integration in automotive electronics, industrial controls, telecommunications, and general-purpose transient voltage suppression.
