The DB3TG is a bi-directional trigger diode (DIAC) from ON Semiconductor, designed for use in AC phase control and triac triggering circuits. It features a break-over voltage of 30V minimum, 32V typical, and 34V maximum, with a symmetry of ±2V. The device conducts a maximum break-over current of 15μA and has a leakage current of 10μA at half the maximum break-over voltage.
This through-hole component is supplied in the JEDEC DO-35 glass package (DO-204AH) with axial leads. The hermetically sealed glass construction and compression bonded assembly deliver high reliability, while the pure tin-plated, lead-free terminals are resistant to corrosion and solderable per MIL-STD-202, Method 208. The device can be soldered at up to 260°C for 10 seconds.
The DB3TG dissipates a maximum of 150mW and can handle repetitive peak forward currents up to 2A (20μs pulse width). It operates over a junction and storage temperature range of -40°C to +125°C, with a typical thermal resistance of 400°C/W junction-to-ambient. These characteristics make it suitable for solid-state switching applications such as lamp dimming and motor speed control.
