STMicroelectronics Uni-Directional TVS Diode 1.5 kW, 2-Pin Surface Mount SMC Package SM15T39A

STMicroelectronics SM15T39A is a high-performance Uni-Directional Transient Voltage Suppressor (TVS) diode designed to protect electronic circuits from voltage transients such as electrical fast transients and lightning surges. This device features a single diode configuration optimized for surface mount PCB assembly in a compact SMC package.

The SM15T39A withstands a peak pulse power of 1.5 kW, making it suitable for use in automotive electronics, industrial controls, telecommunications equipment, and consumer electronics where transient overvoltage protection is critical.

It offers a minimum breakdown voltage of 37.1 V and a maximum reverse standoff voltage of 33.3 V, ensuring fast response to transient events. The clamping voltage of 69.7 V limits spike voltages to safe levels, thereby protecting downstream components.

Physical dimensions of 7.15 mm length, 6.25 mm width, and 2.45 mm height facilitate compact PCB design and space-saving assembly. Its operating temperature range from -55°C to 150°C makes it suitable for demanding environments and temperature variations.

The device has a very low reverse leakage current of 1 μA, which contributes to energy efficiency and reliability of circuits in which it is used. It includes 2 pins and features a standard footprint package type SMC, which is widely supported in manufacturing.
