When AC voltage is CAP013DG 1000 V disconnected, CAPZero automatically discharges the X capacitor by CAP004DG 825 V connecting the series discharge resistors.

Measurements of peak voltage across CAPZero during surge tests should be made with oscilloscope probes having appropriate voltage rating and using an isolated supply to the oscilloscope to avoid ground currents influencing measurement results. When making such measurements, it is recommended that 50 V engineer- D Package (SO-8) ing margin is allowed below the breakdown voltage specification (for example 950 V with the 1000 V CAPZero). 1 8 NC NC If the measured peak Drain voltage exceeds 950 V, an external 1 kV D1 2 7 D2 ceramic capacitor can be placed between D1 and D2 terminals to attenuate the voltage applied between the CAPZero terminals during 3 6 D1 D2 surge. Please refer to the Application Note AN-48 for the details. 4 5 This optional external capacitor placement is shown as C in Figure NC NC EXT 3. It should be noted that use of an external capacitor in this way will increase power consumption slightly due to the C charge/discharge EXT currents flowing in R1 and R2 while AC is connected.

CAPZero If lower dissipation or lower voltage across each resistor is required during fault tests, the total external resistance can be divided into more discrete resistors, however the total resistance must be equal to that specified in Table 1. Safety CAPZero meets safety requirements even if placed before the system X Capacitor input fuse. If a short-circuit is placed between D1 and D2 terminals R1 of CAPZero, the system is identical to existing systems where CAPZero is not used. With regard to open circuit tests, it is not possible to create a fault condition through a single pin fault (for example lifted pin test) since there are two pins connected to each of D1 and D2. If several pins are lifted to create an open circuit, the condition is identical to an open circuit X capacitor discharge resistor in existing systems where CAPZero is not used. If redundancy against open circuit faults is required, two CAPZero and R1 / R2 configurations can be placed in R2 (cid:31)≥4 mm parallel. Discharge Operation To meet the safety regulations, when the AC supply is disconnected, CAPZero will discharge the X capacitor to the safety extra low voltage (SELV) levels according to the above functional description. Although there are no specific safety requirements below SELV, CAPZero still PI-5610-041310 continues the discharge until the X capacitor is fully discharged. As such CAPZero can be safely used at low input voltages such as the Figure 4.
