DB3 DIAC

DB3 DIAC

Used in conjunction with triacs for simplified gate control circuits or as a starting element in fluorescent lamp ballasts.DIAC is a semiconductor device that has three layers and two junctions. The word DIAC consists of two parts, DI and AC. The DI stands for the diode (or two. Like Di, Tri, Quad, Penta, etc.) and AC stands for Alternating Current. DIAC is the acronym of the diode for alternating current. The DIAC is a combination of two diodes in parallel, one in forward bias and the other one is in reverse bias condition with respect to both sides. DIAC is a specially constructed diode, which allows current to pass in both directions when certain conditions are met.

Features: 

• Bidirectional Triggering: Enables conduction in both AC directions, ideal for symmetrical signal control.
• Consistent Switching Behavior: Provides reliable and repeatable triggering, improving circuit stability.
• Compact and Lightweight Design: Easily fits into space-constrained circuits without adding bulk.
• Ideal for Phase Control: Works seamlessly in dimmers and motor speed controllers to manage power delivery smoothly.
• Noise-Free Operation: Helps maintain clean switching without introducing electrical noise into the system.
• Highly Reliable for Long-Term Use: Solid-state construction ensures dependable operation over time.
• Well-Suited for TRIAC Triggering: Specifically designed to trigger TRIACs efficiently in AC control circuits.
