600W bidirectional TVS for 22V rails
The SMBJ22CAE3/TR13: It clamps transients on a 22V nominal rail, with a breakdown voltage minimum of 24.4V and a maximum clamping voltage of 35.5V at the rated peak pulse current of 16.9A. The single bidirectional channel means it protects both polarities of a signal or supply line, making it suitable for AC-coupled or bipolar applications where the transient can swing positive or negative relative to ground.
The SMB footprint is a common industry standard; the same pad pattern is shared with other SMB-packaged TVS diodes, simplifying board layout if a different voltage rating is later substituted.
Microchip lists the SMBJ22CAE3/TR13 as Active.
