Transient Voltage Suppression Diodes
Axial Leaded – 1500W > LCE series
LCE Series
Description
RoHS
The LCE Series is designed specifically to protect sensitive
electronic equipment from voltage transients induced by
lightning and other transient voltage events.
Features
• Glass passivated chip
junction in DO-201
Package
• 1500W peak pulse power
capability at 10×1000μs
waveform, repetition rate
(duty cycles):0.01%
• Fast response time:
typically less than 1.0ps
from 0 Volts to BV min
• Excellent clamping
capability
• Typical failure mode is
short from over-specified
voltage or current
• Whisker test is conducted
based on JEDEC
JESD201A per its table 4a
and 4c
• IEC-61000-4-2 ESD
15kV(Air), 8kV (Contact)
• ESD protection of data
lines in accordance with
IEC 61000-4-2 (IEC801-2)
Applications
TVS devices are ideal for the protection of I/O interfaces,
V
CC
bus and other vulnerable circuits used in telecom,
computer, industrial and consumer electronic applications.
• EFT protection of data
lines in accordance with
IEC 61000-4-4 (IEC801-4)
• Low incremental surge
resistance
• High temperature
soldering guaranteed:
260°C/40 seconds /
0.375”
,(9.5mm) lead
length, 5 lbs., (2.3kg)
tension
• Plastic package has
underwriters laboratory
flammability classification
94V-O
• Matee tin lead–free
plated
• Ideal for data line
applications
• Halogen free and RoHS
compliant
