From this triac there are no datasheet. Maybe a custom made version - go to the attached images.
This triac was in use in a motor speed controller for large drilling machine without integrated speed control unit.
According datasheet on page 6/12 under
https://4donline.ihs.com/images/Vip...2-1.pdf?hkey=6D3A4C79FDBF58556ACFDE234799DDF0
there are only "B", "BW" and "CW" versions but not "IV" version as you will find in the attached images (except the last image - this shows a BW version).
Thanks for an advice for getting this data sheet.

The IV indicates units selected for operation in quadrants 1 and 4 as would be found in a simple phase controlled trigger used for speed control. The requirement is to have the trigger angle identical for the positive and negative half cycles (otherwise considerable DC component is created)
