4 / 15 page 1-236 Regulatory Information The HCPL-7820/7825 has been approved by the following organizations: UL Recognized under UL 1577, Component Recognition Program, FILE E55361. CSA Approved under CSA Component Acceptance Notice #5, File CA 88324. VDE 0884 (06.92) Insulation Characteristics Description Symbol Characteristic Unit Installation classification per DIN VDE 0110, Table 1 for rated mains voltage ≤ 300 V rms I-IV for rated mains voltage ≤ 600 V rms I-III Climatic Classification 40/100/21 Pollution Degree (DIN VDE 0110, Table 1)* 2 Maximum Working Insulation Voltage VIORM 848 V peak Input to Output Test Voltage, Method b** VPR 1591 V peak VPR = 1.875 x VIORM, Production test with tp = 1 sec, Partial discharge < 5 pC Input to Output Test Voltage, Method a** VPR 1273 V peak VPR = 1.5 x VIORM, Type and sample test with tp = 60 sec, Partial discharge < 5 pC Highest Allowable Overvoltage** VTR 6000 V peak (Transient Overvoltage tTR = 10 sec) Safety-limiting values (Maximum values allowed in the event of a failure, also see Figure 22) Case Temperature TS 175 °C Input Power PS,Input 80 mW Output Power PS,Output 250 mW Insulation Resistance at T S, VIO = 500 V R S ≥ 1x1012 Ω *This part may also be used in Pollution Degree 3 environments where the rated mains voltage is ≤ 300 V rms (per DIN VDE 0110). **Refer to the front of the optocoupler section of the current catalog for a more detailed description of VDE 0884 and other product safety requirements. Note: Optocouplers providing safe electrical separation per VDE 0884 do so only within the safety-limiting values to which they are qualified. Protective cut-out switches must be used to ensure that the safety limits are not exceeded. Insulation and Safety Related Specifications Parameter Symbol Value Units Conditions Min. External Air Gap L(IO1) 7.4 mm Measured from input terminals to output (External Clearance) terminals, shortest distance through air Min. External Tracking Path L(IO2) 8.0 mm Measured from input terminals to output (External Creepage) terminals, shortest distance path along body Min. Internal Plastic Gap 0.5 mm Through insulation distance, conductor to (Internal Clearance) conductor, usually the direct distance between the photoemitter and photodetector inside the optocoupler cavity Tracking Resistance CTI 175 V DIN IEC 112/VDE 0303 Part 1 (Comparative Tracking Index) Isolation Group III a Material Group (DIN VDE 0110, 1/89, Table 1) Option 300 – surface mount classification is Class A in accordance with CECC 00802.
