STMicroelectronics SMA4F11A is a 1-Element Uni-Directional Transient Voltage Suppressor (TVS) Diode with a peak pulse power dissipation of 400 W (10/1000 μs) and a 2-pin SMA flat surface mount package. It is engineered to protect sensitive electronic circuits from transient surges and electrostatic discharges, thereby enhancing circuit robustness and longevity.
This device features a uni-directional diode configuration with a minimum breakdown voltage of 12.3 V and a maximum reverse stand-off voltage of 11 V. The diode offers a low leakage current of 0.2 μA at 25 °C, rising slightly to 1 μA at 85 °C, which helps in maintaining circuit efficiency and reducing power loss.
The SMA4F11A is housed in a compact, flat package with dimensions of 4.6 mm length, 2.9 mm width, and a low profile height of 1.05 mm, making it suitable for high-density surface mount assembly processes.
It supports a peak pulse current of 96 A and has a maximum operating temperature of 175 °C, ensuring high reliability even in demanding thermal environments. The matte tin plating on the leads improves solderability while enhancing corrosion resistance for long-term stability.
This TVS diode series is widely used in industrial electronics, telecommunications, automotive circuits, power supply units, and other applications requiring robust ESD protection and transient voltage suppression.
Uni-directional diode for transient voltage suppression. 400 W peak pulse power dissipation protects against high surge events. Compact SMA flat surface mount package for space-saving designs. Low leakage current minimizes impact on circuit performance.
