Product details

Clamping voltage and peak pulse rating

The SMBJ30A-13-F: Its 30V reverse standoff voltage (V_RWM) means it stays transparent below the protected line's normal operating voltage, only clamping when the surge exceeds the 33.3V minimum breakdown voltage (V_BR). The 600W figure is the product of clamp voltage and peak current at the specified pulse shape; for shorter pulses the peak power capability is higher per the TVS derating curve.

Package and board integration

The SMB package body is larger than the SMA variant, offering better thermal dissipation for the 600W pulse rating — the copper pad area on the PCB under the cathode tab directly influences the junction-to-ambient thermal resistance during the surge.

The part is rated for General Purpose applications, meaning it is not qualified to AEC-Q101 automotive stress standards. For designs requiring automotive-grade TVS, the AEC-Q101 version of the same die in the same package carries a different ordering suffix.

Frequently asked questions

What is the closest pin-compatible alternative to SMBJ30A-13-F in this Circuit Protection family?

Within the same SMBJ series, the SMBJ30A (without the -13-F suffix) is functionally identical — same 30V standoff, same 600W rating, same DO-214AA package. The difference is packaging: -13-F denotes a specific tape-and-reel reel size and lead-free finish. For a BOM that already specifies the -13-F suffix, confirm the reel quantity and finish requirement before substituting the base part number.
