Résumé :
A high power light triggered triac with novel gate structure is presented, which consists of two
thyristors connected in inverse parallel and one light emitting diode provided over a cone-shaped
groove light sensitive gate between the thyristors. The light trigger characteristics have been
studied, and some manufacturing techniques are also described. A 500-A, 1200-V, 40-mm diameter
light triggered triac has been developed.
This device has the characteristics of the minimum light triggering power of less than 15 mw, the
on-state voltage of less than 1.6 V, the commutating dV/dt capability of 100 V//spl mu/s, and the
commutating di/dt capability of 50 A//spl mu/s.
