2. Gate Triggering: TRIACs can be activated by applying a small current to the gate terminal. This feature allows for precise control over the timing of when the TRIAC turns on, enabling applications such as phase control in dimmers and motor speed controllers. The ability to trigger the TRIAC at specific points in the AC cycle enhances the efficiency and performance of the circuit.

3. Zero-Crossing Detection: Many TRIAC applications incorporate zero-crossing detection to minimize electrical noise and reduce stress on the device. By ensuring that the TRIAC is turned on at the moment the AC voltage crosses zero, this technique helps to limit inrush current and prolong the life of the TRIAC.

4. Snubber Circuits: To protect TRIACs from voltage spikes and transients, snubber circuits—typically composed of resistors and capacitors—are employed. These circuits absorb excess energy and safeguard the TRIAC from potential damage, ensuring reliable operation in various environments.

5. Thermal Management: TRIACs generate heat during operation, necessitating effective thermal management strategies. Utilizing heat sinks, thermal pads, or other cooling methods is crucial to maintain the TRIAC's performance and longevity, especially in high-power applications.
