Overview
TIGER ELECTRONIC CO.
,LTD DB3/DB4 Silicon Bidirectional Diacs VOLTAGE RANGE: 28-45 V DO-35 Features The three layer,two termnal,axial lead,hermetically 1111sealed diacs are designed specifically for triggering 1111thyristors.
They demonstrate low breakover current at 1111breakover voltage as they withstand peak pulse 1111current,The breakover symmetry is within three 1111volts(DB3,DB4).
These diacs are intended for use in CCCthyrisitors phase control,circuits for lamp dimming, FFFI universal motor speed control,and heat control.
ABSOLUTE RATINGS Parameters Symbols Dimensions in inches and (millimeters) DB3,DB4 UNITS Power dissipation on printed TA=50oC circuit (L=10mm) Pc Repetitive peak on-state current tp=20 S f=120Hz ITRM Operating junction temperature TJ Storage temperature TSTG ELECTRICAL CHARACTERISTICS 150.
