Silicon Bidirectional Diac TO-DO35 Transient Voltage Suppressor Diode
Features
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.
JF's 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
