E.S.D NOISE CLIPPING DIODES
NNCD3.3A to NNCD12A
ELECTROSTATIC DISCHARGE NOISE CLIPPING DIODES
(400 mW TYPE)
This product series is a diode developed for E.S.D (Electrostatic
Discharge) noise protection. Based on the IEC1000-4-2 test on
electromagnetic interference (EMI), the diode assures an endur-
ance of no less than 30 kV.
Type NNCD2.0A to NNCD12A Series is into DO-34 Package
(Body length 2.4 mm MAX.) with DHD (Double Heatsink Diode)
construction having allowable power dissipation of 400 mW.
