DB3 Diac
The DB3 DIAC is a bidirectional semiconductor device that conducts current only after its breakdown voltage (typically 28V to 36V) is exceeded. It has no polarity and is mainly used to trigger TRIACs and SCRs in AC phase control circuits
Breakover voltage: ~32V
Peak current: 2A
Operating temp: -40°C to 125°C
Used for triggering TRIACs in AC control circuits.
#Applications of the DB3 DIAC include:
Light dimmers
Motor speed controls
Phase control circuits
Heat controls
Inrush current limiting
