1SMA18AT3G Description

Short technical summary and product information.

The 1SMA18AT3G is a unidirectional TVS diode from On Semiconductor designed for general purpose circuit protection. It features a reverse standoff voltage of 18V and a clamping voltage of 29.2V at a peak pulse current of 13.7A. With a peak pulse power rating of 400W, it provides robust protection against transient voltage spikes. The device has a capacitance of 645pF at 1MHz and is not intended for power line protection. It is housed in a 6-WDFN exposed pad package (6-TDFN-EP 3x3mm) for surface mount assembly. The operating temperature range is -65°C to 150°C. This diode is suitable for general purpose applications requiring reliable ESD and surge protection.
