TVS Diode & Diacs

Trigger Diode

Trigger Diode Bi-directional Trigger Diodes (also known as Diac) is a diode that conducts current only after its breakover voltage has been reached momentarily. Functioning as a trigger diode with a fixed voltage reference, the DB3/DB4/LLDB3 series can be used in conjunction with triacs for simplified gate control circuits or as a starting element in fluorenscent lamp ballasts.

TVS Diode

The Transient Voltage Suppressor diode (also known as a TVS Diode) is a protection diode designed to protect electronic circuits against transients and overvoltage threats such as EFT (electrically fast transients) and ESD (electro-static discharge). TVS Diodes are silicon avalanche devices typically chosen for their fast response time (low clamping voltage), lower capacitance and low leakage current. Topdiode offer below TVS diodes:
