Transient Voltage Suppression Diodes
Surface Mount – 600W > SMA6L series
SMA6L Series
Uni-directional
Description
RoHS
Pb
e3
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.

Notes:
1. Non-repetitive current pulse, per Fig.4 and derated above T
J
(initial) =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.

based on JEDEC
JESD201A per its table 4a
and 4c
• IEC-61000-4-2 ESD
30kV(Air), 30kV (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 V

• Pb-free E3 means 2nd
level interconnect is
Pb-free and the terminal
finish material is tin(Sn)
(IPC/JEDEC J-STD-
609A.01)
TVS devices are ideal for the protection of I/O Interfaces,
