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

finish material is tin(Sn)
(IPC/JEDEC J-STD609A.01)
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.
