CAP200DG CAPZero™-2
Zero1 Loss Automatic X Capacitor Discharge IC
Product Highlights
• One part to cover X capacitor values from 100 nF to 6 mF • Blocks current through X capacitor discharge resistors when AC
voltage is connected • 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 • >4 mm creepage on package and PCB • Self supplied – no external bias required • High common mode surge immunity – no external ground connection • High differential surge withstand – 1000 V internal MOSFETs • NEMKO and CB certification (issued by UL and NEMKO)
