TransientVoltage Suppression Diodes
Surface Mount – 600W > SMA6L series
RoHS
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 andThermal Characteristics
(TA=25OC unless otherwise noted)
• SMA low profile package:
less than 1.1 mm
• Same power as standard
.• Low inductance,
excellent clamping
capability
