SMA6L12A Description

Short technical summary and product information.

The SMA6L12A is a 600W peak pulse power unidirectional TVS diode from Littelfuse. It is designed for general purpose transient voltage suppression. Key electrical characteristics include a reverse standoff voltage of 12V, a minimum breakdown voltage of 13.3V, and a maximum clamping voltage of 19.9V at 30.2A peak pulse current.

 

The device is housed in a DO-221AC (SMA Flat Leads) package, suitable for surface mount assembly. The operating temperature range is -65°C to 150°C. It is listed as RoHS3 compliant and has a moisture sensitivity level of 1 (unlimited).

 

This TVS diode is intended for general purpose use where circuit protection against transient voltage spikes is required. It is not designed for power line protection. The single unidirectional channel makes it appropriate for protecting DC lines and signal lines.
