Notes:
1. Package contour optional within dimensions A and C. Slugs, if any, shall be included
within this cylinger but shall not be subject to
the minimum limit of Dimention A.
2. Lead diameter is not controlled in this zone to allow for flash, lead finish build-up and
minor irregularities other than slugs.
Careful selection of the correct device for the application’s
operating parameters and environment will go a long
way toward extending the operating life of the Thyristor.
Overheating and surge currents are the main killers of
DIACs. Correct mounting, soldering, and forming of the
leads also help protect against component damage.
