ELECTROSTATIC DISCHARGE NOISE CLIPPING DIODES
(QUARTO TYPE : COMMON ANODE)
5 PIN MINI MOLD
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.
With four elements mounted in the 5 PIN Mini Mold Package, the
product can cope with high density and automatic packaging.

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 (11 product name lined up).
• With 4 elements mounted (common anode) mounted in the 5 PIN
automatic packaging.
MINI MOLD package, the product can achieve a high density and
