DB3

DB3 / DB4 Features The three layer, two terminal, axial lead, hermetically sealed diacs are designed specifically for triggering thyristors. www.DataSheet4U.com They demonstrate low breakover current at breakover voltage as they withstand peak pulse current. The breakover symmetry is within three volts. These diacs are intended for use in thyristors phase control, circuits for lamp dimming, universal motor speed control, and heat control DEC's DB3/DB4 are bi-directional trigged diode designed to operate in conjunction with Triacs and SCR's SIGNAL BIDIRECTIONAL DIAC DO-35(GLASS) 0.075(1.9) MAX.
