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.
NH'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
Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC
