Yep, 1.5KE220CA is the exact part number you need. (The 'CA' at the end of the part number means bidirectional, if it were just 'A' then it would be uni-directional)
Be aware though that the two TVS diodes you need are different part numbers!
VR4 - 1.5KE220CA
VR5 - 1.5KE250CA
Be sure to get one of each type and install them in the correct locations! :)
