Notes:
1. Non-repetitive current pulse, per Fig.4 and derated above TA=25ºC per Fig. 3.
2. Mounted on 5.0x5.0mm copper pad to each terminal.
3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional
device only.
The TPSMA6L series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by load dump and other transient voltage
events, and it’s especially suitable for high reliability and
automotive application.
SMA low profile package (DO221-AC) has the same
electronical performance as the SMB package but with low
height profiles (1.1mm).
Applications
TVS devices are ideal for the protection of I/O Interfaces,
VCC bus and other vulnerable circuits used in Telecom,
Computer, Industrial and Consumer electronic applications.
• Same power as standard
SMB devices (600 W)
• Hi reliability application
and automotive grade
AEC Q101 qualified
• SMA low profile package:
less than 1.1 mm
• Footprint compatibility
with standard SMA and
SMB products (easy to
layout)
• 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
15kV(Air), 8kV (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
• Low inductance, excellent
clamping capability
• Fast response time:
typically less than 1.0ns
from 0 Volts to VBR min
• Built-in strain relief
• Glass passivated junction
• High temperature
soldering: 260°C/10
seconds at terminals
• Plastic package has
underwriters laboratory
flammability V-0
• Typical maximum
temperature coefficient
ΔVBR = 0.1% x VBR@25°C x ΔT
• 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)
