E.S.D NOISE CLIPPING DIODES
NNCD3.3C to NNCD12C
ELECTROSTATIC DISCHARGE NOISE CLIPPING DIODES
(150 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, thus making itself most suitable for
external interface circuit protection.
Type NNCD3.3C to NNCD12C Series are into 2PIN Ultra Super
Mini Mold Package having allowable power dissipation of 150 mW.

FEATURES
• Based on the electrostatic discharge immunity test (IEC1000-4-
2), the product assures the minimum endurance of 30 kV.
• Based on the reference supply of the set, the product achieves
a series over a wide range (15 product name lined up).
