Description
™ CAPZero Family
Zero1 Loss Automatic X Capacitor Discharge IC
Product Highlights
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
