I damaged a BMS board by briefly shorting some connector leads. The only chips I see that appear physically damaged at the two marked by the red box in the image below. I can't seem to find those components in my usual places. Anyone have ideas that could point me in the right direction?

Thanks for your help. Any suggestions would be welcome.

They are 18V unidirectional TVS diodes: SMBJ18A.

Their marking code is LT, not P636.
