Tool/software:
Hello, I am Makoto.
Datasheet says,
The SMBJ33CA TVS diode can be used for 12-V battery protection application. The breakdown voltage of 36.7
V meets the jump start, load dump requirements on the positive side and 16-V reverse battery connection on the
negative side. During ISO 7637-2 pulse 1 test, the SMBJ33CA clamps at –44 V with 12 A of peak surge current
and it meets the clamping voltage ≤ 44 V.
I cannot understand how to select TVS SMBJ33CA. It clamps at -44V with 12A peak surge current.
Where the 12A comes from?
SMBJ33CA is 11.3A of Ip-p.
