Parameter Symbol Min Typ Max Unit Test Conditions/Comments Resistance (Input to Output)1 RI-O 1012 Ω Capacitance (Input to Output)1 CI-O 2.2 pF f = 1 MHz IC Junction to Ambient Thermal Resistance θJA 105 °C/W Thermocouple located at center of package underside, test conducted on 4-layer board with thin traces 1 The device is considered a 2-terminal device: Pin 1 to Pin 4 are shorted together, and Pin 5 to Pin 8 are shorted together. INSULATION AND SAFETY-RELATED SPECIFICATIONS Table 4. Parameter Symbol Value Unit Test Conditions/Comments Input-to-Output Momentary Withstand Voltage VISO 5000 min V 1-minute duration Minimum External Air Gap (Clearance) L(I01) 8.1 min1, 2 mm Measured from input terminals to output terminals, shortest distance through air Minimum External Tracking (Creepage) L(I02) 8.1 min1 mm Measured from input terminals to output terminals, shortest distance path along body Minimum Internal Gap (Internal Clearance) 0.034 min mm Insulation distance through insulation Tracking Resistance (Comparative Tracking Index) CTI >400 V DIN IEC 112/VDE 0303 Part 1 Isolation Group II Material Group (DIN VDE 0110, 1/89, Table I) 1 In accordance with IEC 60950-1 guidelines for the measurement of creepage and clearance distances for a pollution degree of 2 and altitudes ≤2000 meters. 2 Consideration must be given to pad layout to ensure the minimum required distance for clearance is maintained. REGULATORY INFORMATION Table 5. UL1 CSA VDE2 Recognized under 1577 Component Recognition Program1 Approved under CSA Component Acceptance Notice 5A Certified according to DIN V VDE V 0884-10 (VDE V 0884-10):2006-122 5000 V rms Isolation Voltage Single Protection Basic insulation per CSA 60950-1-07 and IEC 60950-1, 810 V rms (1145 VPEAK) maximum working voltage3 Reinforced insulation per DIN V VDE V 0884-10 (VDE V 0884-10):2006-12, 1250 VPEAK Reinforced insulation per CSA 60950-1-07 and IEC 60950-1, 405 V rms (583 VPEAK) maximum working voltage3 Reinforced insulation per IEC 60601-1, 250 V rms (353 VPEAK) maximum working voltage File E214100 File 205078 File 2471900-4880-0001 1 In accordance with UL 1577, each AD7402-8 is proof tested by applying an insulation test voltage ≥ 6000 V rms for 1 second (current leakage detection limit = 15 µA). 2 In accordance with DIN V VDE V 0884-10, each AD7402-8 is proof tested by applying an insulation test voltage ≥ 2344 VPEAK for 1 second (partial discharge detection limit = 5 pC). 3 Rating is calculated for a pollution degree of 2 and a Material Group III. The AD7402 RI-8-1 package material is rated by CSA to a CTI of >400 V and therefore Material Group II. |
