High current triac heating

Webwhere high static and dynamic dV/dt and high dI/dt can occur. This triac will commutate the full RMS current at the maximum rated junction temperature (T j(max) = 150 °C). It is used in applications where "high junction operating temperature capability" is required. 2. Features and benefits • High current TRIAC • Low thermal resistance Web11 de ago. de 2015 · Triac fails unusually. The circuit is a MCU triggered, capacitor based fan speed controller. The circuit works fine when a single triac is connected but when both triacs are wired and triggered alternately, any of the triac fails randomly by shorting. Initial load is a 60W incandescent bulb. The triac gate takes close to 50mA through optocoupler.
