bidirectional trigger diode,
db3 diac diode
Throught Hole Silicon Bidirectional Diac Trigger Diode DB3 DB4 DB6
The three-layer, two-terminal, axial-lead, hermetically sealed diacs are designed specifically for
triggering thyristors. They demonstrate low breakover current at breakover voltage as they
withstand peak pulse current. The breakover symmetry is within three volts(DB3,DC34,DB4) or
four volts(DB6). These diacs are intended for use in thyrisitors phase control , circuits for lamp
dimming, universal motor speed control and heat control.
DB3/DC34/DB4/DB6 are bi-directional triggered diode designed to operate in conjunction with
Triacs and SCR's.
High temperature soldering guaranteed:260 /10 seconds at terminals
· Terminals: Plated axial leads
· Polarity: Color band denotes cathode end
· Mounting Position: Any

Q1: Do you have a test room?
Yes, we have professional staff to take various detection and life test for every batch of diodes, and
special simulation testing equipment aimed at the lighting industry.
Q2: What is your Lead Time?
For general diode and standard printing and packaging request, shipment in 3 days.
For special printing or packaging the first time, normal lead time would be 15 days.
If the order quantity is large, we hope customers place order 15 days in advance for safety.
Q3: Can customers provide logo by themselves?
We can print according to the samples provided by customers if they need special requirement,
but delivery time would be longer because of the extra producing time for printing mold and
Q4: Why choose cooperation with us?
Monthly production capacity up to 300 million pieces and short delivery time.
Factory and products pass ISO9001:2008 certification, all products are conformed to RoHS.
Foreign trade team with more than 10 years of professional export experience can meet various
