1. What precautions should be taken when using TRIACs with inductive loads?
Inductive loads can cause dv/dt turn-on issues. Adding a snubber circuit or using a zero-crossing detection mechanism can prevent premature triggering.
-
2. Why are TRIACs preferred in household electronics?
TRIACs are compact, cost-effective, and capable of handling bidirectional current, making them ideal for small, lightweight, and reliable household devices.
-
3. How does dv/dt affect TRIAC performance?
A high rate of voltage change (dv/dt) across the TRIAC can unintentionally trigger it. Snubber circuits are used to limit dv/dt and ensure reliable operation.
-
4. What are the key parameters to consider when selecting a TRIAC?
Important factors include voltage and current ratings, dv/dt capability, gate sensitivity, and application-specific requirements like power dissipation and thermal management.
