Transient Voltage Suppression Diodes
Surface Mount – 600W > SMA6L series
SMA6L Series
Description
The SMA6L series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
SMA low profile package has the same electronical
performance as the SMB package but with lowest height
profiles (1.1mm) in the industry.
Features
Maximum Ratings and Thermal Characteristics
•S
MA low profile package:
less than 1.1 mm
•S
ame power as standard
SMB devices (600 W)
•F
ootprint 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)
•E
SD protection of data
lines in accordance with
IEC 61000-4-2 (IEC801-2)
•E
FT protection of data
lines in accordance with
IEC 61000-4-4 (IEC801-4)

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.
.• 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
• Typical IR less than 1µA
above 12V
• High temperature
soldering: 260°C/40
seconds at terminals
• Typical maximum
temperature coefficient
ΔVBR = 0.1% x [email protected]°C x ΔT
• Matee tin lead–free plated
• Halogen free and RoHS
compliant
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.
