DB3TG Diac; Ifmax: 2A; DO35; 30÷34V STM

The DB3TG is a high-performance bidirectional trigger diode, commonly known as a DIAC, designed for triggering thyristors and triacs in a variety of AC control applications. Encased in a compact DO35 package, this DIAC boasts a maximum forward current (Ifmax) of 2A and a breakover voltage range of 30 to 34V, making it an ideal choice for precise and reliable triggering. Manufactured by STM, the DB3TG ensures consistent performance and long-term stability. Its symmetrical switching characteristics and low switching voltage make it a crucial component in phase control circuits, light dimmers, motor speed controllers, and other AC power control systems. The DB3TG offers a cost-effective and efficient solution for achieving accurate and dependable triggering in demanding applications.

The DB3TG operates as a bidirectional switch, remaining in a high-impedance state until the voltage across it reaches its breakover voltage (typically between 30 and 34V). Once the breakover voltage is reached, the DIAC rapidly switches to a low-impedance state, allowing current to flow and triggering the connected thyristor or triac. This rapid switching action ensures precise and reliable triggering, minimizing jitter and improving the overall performance of the control circuit. The DB3TG's symmetrical switching characteristics ensure consistent performance regardless of the polarity of the applied voltage.

The DB3TG offers numerous benefits for electronic designers. Its precise breakover voltage ensures accurate triggering of thyristors and triacs. The high maximum forward current allows it to handle significant current loads. The compact DO35 package saves valuable board space. The symmetrical switching characteristics ensure consistent performance. Its low cost and widespread availability make it an attractive option for budget-conscious designs. The DB3TG is a reliable and versatile component that can be used in a wide range of AC control applications.
