DB3/DC34/DB4/DB6

SILICON BIDIRECTIONAL DIAC

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
