Care must be taken to maintain the creepage and clearance distance of a board design to ensure that the mounting pads of the isolator on the printed circuit board (PCB) do not reduce this distance. Creepage and clearance on a PCB become equal in certain cases. Techniques such as inserting grooves or ribs on the PCB are used to help increase these specifications. (2) This coupler is suitable for safe electrical insulation only within the safety ratings. Compliance with the safety ratings shall be ensured by means of suitable protective circuits. (3) Testing is carried out in air or oil to determine the intrinsic surge immunity of the isolation barrier. (4) Apparent charge is electrical discharge caused by a partial discharge (pd). (5) All pins on each side of the barrier are tied together, creating a two-pin device. 7.6 Insulation Specifications PARAMETER TEST CONDITIONS VALUE UNIT GENERAL CLR Minimum air gap (clearance)(1) Shortest pin-to-pin distance through air ≥ 8 mm CPG Minimum external tracking (creepage)(1) Shortest pin-to-pin distance across the package surface ≥ 8 mm DTI Distance through insulation Minimum internal gap (internal clearance) of the double insulation (2 × 0.0135 mm) 0.027 mm CTI Comparative tracking index DIN EN 60112 (VDE 0303-11); IEC 60112 ≥ 600 V Material group According to IEC 60664-1 I Overvoltage category per IEC 60664-1 Rated mains voltage ≤ 300 VRMS I-IV Rated mains voltage ≤ 600 VRMS I-III Rated mains voltage ≤ 1000 VRMS I-II DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12(2) VIORM Maximum repetitive peak isolation voltage At ac voltage (bipolar or unipolar) 1414 VPK VIOWM Maximum-rated isolation working voltage At ac voltage (sine wave) 1000 VRMS At dc voltage 1500 VDC VIOTM Maximum transient isolation voltage VTEST = VIOTM, t = 60 s (qualification test) 7000 VPK VTEST = 1.2 x VIOTM, t = 1 s (100% production test) 8400 VIOSM Maximum surge isolation voltage(3) Test method per IEC 60065, 1.2/50-μs waveform, VTEST = 1.6 x VIOSM = 10000 VPK (qualification) 6250 VPK qpd Apparent charge(4) Method a, after input/output safety test subgroup 2 / 3, Vini = VIOTM, tini = 60 s, Vpd(m) = 1.2 x VIORM = 1697 VPK, tm = 10 s ≤ 5 pC Method a, after environmental tests subgroup 1, Vini = VIOTM, tini = 60 s, Vpd(m) = 1.6 x VIORM = 2263 VPK, tm = 10 s ≤ 5 pC Method b1, at routine test (100% production) and preconditioning (type test), Vini = VIOTM, tini = 1 s, Vpd(m) = 1.875 x VIORM = 2652 VPK, tm = 1 s ≤ 5 pC CIO Barrier capacitance, input to output(5) VIO = 0.5 VPP at 1 MHz 1.2 pF RIO Insulation resistance, input to output(5) VIO = 500 V at TS = 150°C > 109 Ω Pollution degree 2 Climatic category 40/125/21 UL1577 VISO Withstand isolation voltage VTEST = VISO = 5000 VRMS or 7000 VDC, t = 60 s (qualification test), VTEST = 1.2 x VISO = 6000 VRMS, t = 1 s (100% production test) 5000 VRMS |
