Its minimum breakdown voltage is 56.7V, and the clamping voltage at peak pulse current reaches 82.4V max — which means the protected circuitry must tolerate that ceiling during a surge event.
Microchip lists the SMBJ51CAE3/TR13 as Active.
Yes, it is a bidirectional single-channel TVS diode, meaning it clamps transients of either polarity on the same line.
No, the product status is Active. Microchip has not issued an end-of-life notice for this part.
No — the reverse standoff voltage is 51V, and the breakdown starts at 56.7V. It is designed for 51V nominal rails, not 5V circuits.
