Surface Mount – 1000W > 1KSMB series
RoHS
1KSMB Series
Description
Uni-directional
The 1KSMB series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Bi-directional
Features
• RoHS compliant
• Fast response time:
typically less than 1.0ps
from 0V to BV min
• For surface mounted
applications to optimize
board space
• Excellent clamping
capability
• Low profile package
• Low incremental surge
resistance
• Typical IR less than 1µA
above 12V
• High temperature
soldering guaranteed:
260°C/40 seconds at
terminals
•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

Notes:
1. Non-repetitive current pulse , per Fig. 4 and derated aboveTA = 25°C per Fig. 3.
2. Mounted on copper pad area of 0.2x0.2” (5.0 × 5.0mm) to each terminal.
3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional
device only, duty cycle=4 per minute maximum.
Applications
4. VF<3.5V for VBR<_ 50V and VF<5.0V for VBR>_ 51V.
TVS devices are ideal for the protection of I/O Interfaces,
CC bus and other vulnerable circuits used inTelecom,
Computer, Industrial and Consumer electronic applications.
