Product details

75V bidirectional TVS – 500W surge rating in SMA

Its 500W peak pulse power rating means it can absorb moderate surges typical of industrial control I/O, telecom line cards, or DC power inputs without sacrificing board space.

Reverse standoff is 75V, meaning the diode draws negligible leakage below that voltage. Breakdown starts at a minimum of 83.3V, giving a 8.3V guard band before the TVS begins conducting.

Active production – DO-214AC (SMA) package

Package is DO-214AC (SMA), a surface-mount footprint that reflows with standard lead-free profiles. Operating temperature range is -65°C to 150°C junction, covering industrial and some automotive under-hood environments, though this part is not listed as AEC-Q101 qualified.

Frequently asked questions

Is SMAJ75CE3/TR13 bidirectional?

Yes, it is a single bidirectional channel. It clamps transients of either polarity, so you do not need to worry about orientation on AC or bipolar rails.
