TPSMB-VR Series
Description
The TPSMB-VR series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Features
• High reliability application
and automotive grade AEC
Q101 qualified
• Surface mount component
to minimize board space
• Low profile package
• 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
• ESD protection of data
lines in accordance with
IEC 61000-4-2, 30kV(Air),
30kV (Contact)
• EFT protection of data
lines in accordance with
IEC 61000-4-4
• Glass passivated chip
junction
• 600W peak pulse power
capability at 10/1000μs
waveform, repetition rate
(duty cycles):0.01%
• Fast response time:
typically less than 1.0ns
from 0V to VBR min
• Excellent clamping
capability
• Low incremental surge
resistance
•
Typical IR ≤ 1µA for VR > 10V
• High temperature
soldering guaranteed:
260°C/10 seconds at
terminals
• UL Recognized compound
meeting flammability
rating V-0.
• Meet MSL level1,
per J-STD-020, high
temperature soldering
guaranteed.
• Matte tin lead–free plated
• 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)
• Recognized to UL 497B
as an Isolated Loop Circuit
Protector
Applications
TVS components are ideal for the protection of I/O
Interfaces, VCC bus and other vulnerable circuits used in
Automotive applications.
