SMA6T30AY Description

Short technical summary and product information.

The SMA6T30AY is a 600W peak pulse power Zener TVS diode designed for automotive applications. It features a reverse standoff voltage of 25.6V and a maximum clamping voltage of 53.5V at 75A peak pulse current (8/20µs waveform). This unidirectional device is surface mount packaged in a DO-214AC (SMA) case, making it suitable for automated assembly.

 

With an operating temperature range of -40°C to 150°C, the SMA6T30AY is built to withstand harsh automotive environments. It does not include power line protection, indicating it is intended for signal line or low-voltage bus protection rather than main power rail clamping.

 

The part is RoHS3 compliant and has an MSL of 1 (unlimited), simplifying handling and storage. Its compact SMA footprint allows for space-efficient PCB layouts in automotive electronic control units, sensors, and infotainment systems.
