TDA1024 DIP-8 Mains-Zero Triac-Triggering Circuit

The TDA1024 is a monolithic integrated circuit intended for use in ON/OFF control of triacs in static switching applications. It incorporates zero voltage point triggering to minimize radio interference. The TDA1024 is mainly intended for applications such as switching resistive loads and replacing mechanical thermostats in, for example:
- central heating installations,
- washing machine heaters,
- water heaters,
- smoothing irons.
