2CW035XXXYQ-PX
2CW035XXXYQ-PX SERIES ZENER DIODE CHIPS FOR GLASS SEAL WITH
ASYMMETRY LIMITS
DESCRIPTION
Ø
2CW035XXXYQ-PX series are low-power zener diode chips
for glass seal that fabricated in silicon epitaxial planar
technology.
Ø
The series is asymmetrical regulator voltage chips, that is
the upper limit and lower limit is asymmetrical, e.g. Vz=3.0V
chips: the upper limit is 3.25V, the lower limit Is 2.95V ,the
specification is better suitable for customer’ using habit
s
Ø
For customer convenient selecting regulator voltage in
narrow limit. The series divided into 4 types for given
regulator voltage and named PA, PB, PC and PD
respectively.
Ø
The chip thickness is 140µm. The top electrode material is
Ag bump, and the backside electrode material is Ag.
Ø
Chip size: 0.35 X 0.35 (mm)
