e3
The 15KPA Series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Bi-directional
Features
• Glass passivated chip
junction in P600 package
• 15000W peak pulse
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
30kV(Air), 30kV (Contact)
• ESD protection of data
lines in accordance with
IEC 61000-4-2
• EFT protection of data
lines in accordance with
IEC 61000-4-4
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.
Additional Infomarion
• Low incremental surge
resistance
• Typical I
