The SMBJ20CA-13: It clamps a 20V nominal rail at 32.4V maximum, with a breakdown voltage starting at 22.2V. The 18.5A peak pulse current handling means it can absorb a substantial surge without letting the protected line exceed the clamping ceiling.
The SMB footprint is forgiving under hot air: the body is large enough to grip with tweezers, and the solder joints are visible for inspection.
The SMBJ20CA-13 is a Zener TVS diode in the SMBJ series, bidirectional, with a single channel.
