CAPZero Family  
Zero1 Loss Automatic X Capacitor Discharge IC  
Product Highlights  
R1  
Blocks current through X capacitor discharge resistors when AC  
voltage is connected  
D1  
Automatically discharges X capacitors through discharge resistors  
when AC is disconnected  
Simplifies EMI filter design – larger X capacitor allows smaller  
inductive components with no change in consumption  
Only two terminals – meets safety standards for use before or after  
system input fuse

When AC voltage is applied, CAPZero™ blocks current flow in the X  
capacitor safety discharge resistors, reducing the power loss to less  
than 5 mW, or essentially zero1 at 230 VAC. When AC voltage is  
disconnected, CAPZero automatically discharges the X capacitor by  
connecting the series discharge resistors. This operation allows total  
flexibility in the choice of the X capacitor to optimize differential mode  
EMI filtering and reduce inductor costs, with no change in power  
consumption.

Designing with CAPZero is simply a matter of selecting the appropriate  
CAPZero device and external resistor values in Table 1 for the  
X capacitor value being used. This design choice will provide a worst  
case RC time constant, when the AC supply is disconnected, of less  
than 1 second as required by international safety standards.

The simplicity and ruggedness of the two terminal CAPZero IC makes it  
an ideal choice in systems designed to meet EuP Lot 6 requirements.

The CAPZero family has two voltage grades: 825 V and 1000 V. The  
voltage rating required depends on surge requirement and circuit  
configuration of the application. See Key Applications Considerations  
section for details.

Notes:  
1. IEC 62301 clause 4.5 rounds standby power use below 5 mW to zero.  
2. Values are nominal. RC time constant is <1 second with ±20% X capacitor  
and ±5% resistance from these nominal values.  
3. Lowest value of discharge resistor that can be used.  
4. Packages: D: SO-8.
