DB6 Trigger Diode 2A 70V - Low Leakage Rectifier from China Suppliers and Factory for Lighting Electronics
Function
Thyristor Triggering
When the AC voltage exceeds the threshold of 60V (typical value, 56–70V), the DB6 conducts instantly, providing trigger pulses to the gate of TRIAC/SCR.
It controls the conduction angle to realize power regulation such as dimming, speed regulation, and temperature control.
AC Phase Control
Cooperating with RC timing circuits, it accurately controls the starting point of conduction in each AC half-cycle to achieve smooth power regulation without DC bias.
This characteristic makes it ideal for 110V/220V AC applications.
Startup & Protection
It is used for startup triggering in fluorescent lamp/LED ballasts, heaters, motor drive circuits, etc.
It can also serve as a simple overvoltage protection component to trigger the protection circuit before the voltage exceeds the limit.

FAQ
A1: Their core electrical functions are identical; the plastic-encapsulated version only changes the package type. Compared with glass-encapsulated DB6, the plastic-encapsulated one is moisture-proof, mechanical shock-resistant and vibration-resistant.
It supports tape-and-reel packaging and automated processes like reflow/wave soldering, making it more suitable for industrial mass production and complex environments such as humidity and vibration.
