The SMA6T18AY is a 600W unidirectional TVS diode manufactured by STMicroelectronics. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge.
Key electrical specifications include a reverse standoff voltage of 15.3V, a clamping voltage of 32.3V at a peak pulse current of 123A (8/20µs waveform), and a peak pulse power rating of 600W. The device uses Zener technology and is not intended for power line protection.
The SMA6T18AY is housed in a DO-214AC (SMA) surface-mount package and supports an operating junction temperature range of -40°C to +150°C. It is suitable for automotive applications and is RoHS3 compliant, REACH unaffected, with an MSL of 1 (unlimited).
