| BL GALAXY ELECTRICAL SURFACE MOUNT RECTIFIER SODDB3 VBO: 28 -- 45 V SODDB4 FEATURES oThe 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.These diacs are intended for use in thyrisitors phase control, circuits for lamp dimming,universal motor speed control,and heat control. 5 SOD-123FL 1.8 0.1 1.0 0.2 5a 2.8 0.1 0.05 0.30 0.98 0.1 0.60 0.25 MECHANICAL DATA o Case:JEDEC SOD-123FL,molded plastic over passivated chip o Weight: 0.006 ounces, 0.02 gram 3.7 0.2 ABSOLUTE RATINGS Parameters Device marking code Power dissipation on printed circuit (L=10mm) T A= 50 ae Repetitive peak on-state current tp=20s, f=120Hz Operating junction temperature Storage temperature Pc ITRM Tj TSTG SODDB3 DB 150 2.0 - 40 --- + 125 SODDB4 DC UNITS mW A ae ae - 40 --- + 125 ELECTRICAL CHARACTERISTICS Parameters Test Conditions C=22nF** See FIG.1 C=22nF** See FIG.1 I =(IBOu IF=10mA) See FIG.1 See FIG.2 C=22nF** See FIG.3 VR=0.5VBO Min Typ Max Max SODDB3 SODDB4 28 32 36 3.0 35 40 45 UNITS Breakover voltage * VBO |+VBO||-VBO| |V| VO IBO tr IR V Breakover voltage symmetry V Dynamic breakover voltage * Output voltage * Breakover current * Rise time* Leakage current NOTE: * Min Min Max Typ Max 5.0 5.0 100 1.5 10 V V A s A www.galaxycn.com * Electrical characteristics applicable in both forward and reverse directions. ** Connected in parallel with the devices.
