The DB31 from Diotec Semiconductor is a Diac that is ideal for trigger of triacs and thyristors, AC switches and controls, dimmer circuits, and commercial-grade applications. It has a break-over voltage of up to 34 V and a break-over current of less than 200 µA. This diac has a power dissipation of less than 150 mW. It can conduct in both the directions, thereby providing bidirectional switching operations and is protected against false triggers by light. This RoHS-compliant diac is available in a through-hole package that measures 62.5 x 3.9 mm.
