Product details

Transient protection window and what the ratings mean for the board

The SMBJ43A-13-F: Its 43 V reverse standoff voltage means the diode stays off below that level, so it does not leak into the protected circuit during normal operation. The unidirectional channel means it clamps only one polarity; for AC or bidirectional lines you would need two devices or a bidirectional part.

The general-purpose application tag means it fits across DC power inputs, I/O lines, and low-frequency signal ports where the 10/1000 µs waveform is representative.

Sourcing and lifecycle posture

No stock-holding claim; each RFQ is confirmed on the spot market or factory lead time.

Frequently asked questions

Where can I buy SMBJ43A-13-F and how do I get a price?

The SMBJ43A-13-F is available to order through independent and authorized distribution.

What is SMBJ43A-13-F's listed type on this Circuit Protection line?

The SMBJ43A-13-F is a Zener-type TVS diode. It uses the Zener avalanche breakdown mechanism to clamp overvoltage transients on a 43 V rail.
