SM6F18AY Description

Short technical summary and product information.

The SM6F18AY is a unidirectional Zener TVS diode from STMicroelectronics designed to protect sensitive electronics from voltage transients. It features an 18V reverse standoff voltage (Vrwm) and a maximum clamping voltage of 39.3V at a peak pulse current of 102A (8/20µs). The device can handle 600W of peak pulse power, making it suitable for moderate surge protection applications.

 

This TVS diode is housed in a compact SOD-128 surface mount package (SOD128Flat), enabling space-efficient PCB layouts. It operates over a wide junction temperature range of -55°C to 175°C, ensuring reliability in harsh environments. The component is rated for surface mount assembly and is compatible with standard reflow soldering processes.

 

Designed for automotive applications, the SM6F18AY meets the rigorous demands of vehicle electronics. It does not include power line protection, so it is best suited for signal or low-power rail protection. The unidirectional configuration provides precise clamping for positive transients. For complete design verification, refer to the official STMicroelectronics datasheet.
