Product Description
STMicroelectronics SMA4F13A is a single-element uni-directional Transient Voltage Suppressor (TVS) diode designed to safeguard sensitive circuits against high-energy transient surges. Featuring planar technology, it delivers low leakage current and high junction temperature capability, ensuring reliability and long-term stability in demanding environments.
This diode supports a peak pulse power dissipation of 400 W (10/1000 μs) and an even higher 2.5 kW (8/20 μs) rating, packaged in a flat, thin SMA surface mount package measuring 4.6 mm by 2.9 mm with a height of 1.05 mm. Its minimum breakdown voltage is 14.4 V, while the maximum reverse stand-off voltage is 13 V, providing robust protection for diverse circuits.
With a clamping voltage of 27.2 V and a maximum peak pulse current of 85 A, the SMA4F13A efficiently clamps voltage spikes, preventing damage from electrostatic discharges, inductive load switching, and lightning transients. It operates effectively in a wide temperature range from -55°C to 175°C, making it suitable for various industrial, automotive, and consumer electronic applications.
The device incorporates matte tin plating on leads to enhance solderability and corrosion resistance. Its low leakage current - 0.2 μA at 25 °C and 1 μA at 85 °C - minimizes power loss and maintains energy efficiency within protected circuits.
