Descriptions
The 15KPA-HR High Reliability Series is designed
specifically to protect sensitive electronic equipment from
voltage transients induced by lightning and other transient
voltage events.
Features
• 15 kW peak pulse
capability at 10/1000μs
waveform, repetition rate
(duty cycles):0.01%
• Glass passivated chip
junction in P600 package
• Fast response time:
typically less than 1.0ps
from 0 Volts to VBR 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)
• EFT protection of data
lines in accordance with
IEC 61000-4-4
• Low incremental surge
resistance
wTyhpeicnaVl IBRR
less than 2μA
min>36V
• High temperature
soldering guaranteed:
260C/10 seconds / 0.375”,
(9.5mm) lead length, 5
lbs., (2.3kg) tension
• Vx(αBR(1T@:+TαeTmJT=pxVeB(rTRa@Jtu-2r25e5°C))
Coefficient, typical value
is 0.1%)
• UL Recognized compound
meeting flammability
rating V-0
• Lead-free matte tin plated
package
• Halogen free and RoHS
compliant
• Pb-free E3 means 2nd
level interconnect is Pb-
free and the terminal finish
material is tin(Sn) (IPC/
JEDEC J-STD-609A.01)
