Niu Hang Electronic Co. Ltd Production Data Sheet LLDB3,LLDC34,LLDB4,LLDB6 SILICON BIDIRECTIONAL DIAC VOLTAGE LL-34 150mWatts DISSIPATION 28-56Volts Unit:Inch(mm) 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 MECHANICAL DATA Case: MiniMELF glass case(SOD-80) Weight: Approx. 0.05 gram Ƶ ABSOLUTE MAXIMUM RATINGS Value Parameters Symbols Units LLDB3 PC Power Dissipation on Printed Circuit(L=10mm) TA=50 C ITRM Repetitive Peak on-state Current tp=10ms f=100Hz TSTG/TJ Ƶ LLDB4 LLDC34 LLDB6 mW 150 Storage and Operating Junction Temperature A 1.6 2.0 C -40 to+125 ELECTRICAL CHARACTERISTICS (Tj=25℃ unless otherwise specified) Value Symbols Parameters Units Test Condition LLDB3 VBO │+VBO││-VBO│ │+ V│ Breakover Voltage (Note 2 ) C=22nF(Note 2) See diagram 1 Min Typ Max Breakover Voltage Symmetry C=22nF(Note 2) See diagram 1 Max I=(IBO to IF=10mA) See Diagram 1 Dynamic Breakover Voltage (Note1) 28 32 36 LLDC34 LLDB4 35 40 45 LLDB6 56 60 70 V +3 +4 V Min 5 10 V V 30 34 38 VO Output Voltage (Note 1 ) See Diagram 2 Min 5 IBO Breakover Current (Note1) C=22nF(Note 2) Max 100 mA See Diagram 3 Typ 1.5 ms VB=0.5 VBO max see diagram 1 Max 10 mA tr IB Rise Time (Note1) Leakage Current (Note1) Notes: 1.Electrical characteristics applicable in both forward and reverse directions. 2.Connected in parallel with the devices. http://www.dgniuhang.com Date:2014/10/20 Rev.:AA Page: 1 of 5 Niu Hang Electronic Co.
