Transient Voltage Suppression Diodes
Surface Mount – 1500W > SMCG-HR series
SMCG-HR Series
Description
RoHS
Pb
e3
The SMCG-HR series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Features
• High-Reliability up-
screened for critical
applications require higher
reliability performance
and low infant mortality
failures.
• Excellent clamping
capability
• Low incremental surge
resistance
• Typical I
R
less than 1µA
above 12V
• For surface mounted
applications to optimize
board space
• L bend lead forming gives
best solderbility for Hi
reliability application
• ypical failure mode is
T
short from over-specified
voltage or current
• hisker test is conducted
W
based on JEDEC
JESD201A per its table 4a
and 4c
• EC-61000-4-2 ESD
I
15kV(Air), 8kV (Contact)
• SD protection of data
E
lines in accordance with
IEC 61000-4-2 (IEC801-2)
• FT protection of data
E
lines in accordance with
IEC 61000-4-4 (IEC801-4)
• Built-in strain relief
• Fast response time:
typically less than 1.0ps
from 0V to BV min
• 1500W peak pulse power
capability at 10/1000μs
waveform, repetition rate
(duty cycles):0.01%
