Product details

What the ratings mean for your board

The SMBJ30CA-13-F: The 30 V reverse standoff voltage is the DC or peak-AC voltage the diode lets pass without conducting — your rail must stay below this in normal operation. A single bidirectional channel means one device protects a signal pair against both polarities — no need for two unidirectional parts back-to-back. The DO-214AA (SMB) package is a standard surface-mount footprint with a low profile — it reflows cleanly with a typical 260 °C peak solder profile. The -55 °C to 150 °C junction range covers automotive under-hood and industrial enclosure ambient without derating the power curve at the high end.

Frequently asked questions

What is the clamping performance of SMBJ30CA-13-F?

At the rated 12.4 A peak pulse current (10/1000 µs waveform), the maximum clamping voltage is 48.4 V. The minimum breakdown voltage is 33.3 V, so the device starts conducting between those points.

Is SMBJ30CA-13-F a bidirectional or unidirectional TVS?

It is a single bidirectional channel — one device clamps transients of either polarity on a signal pair.

What package does SMBJ30CA-13-F use?

The DO-214AA (SMB) surface-mount package. The supplier device package is also designated SMB.
