SLD SERIES
The SLD series is specifically designed for automotive
applications, available in both unidirectional and bidirectional.
6
The SLD 10U is designed to be used in series, for example three
10Us in series for a 30 volt working; this configuration will
provide a very high power (a multiple of 3) capability and is a far
superior solution than using devices in parallel, which will require
closely matched devices in order to prevent ‘current hogging’
and consequently, damage to the device.
FEATURES
• RoHS Compliant
• 2200 Watts Peak Power rated with 100µS/150mS pulse
(applies to a single device)
• 50,000 Watts Peak Pulse Power based on 8/20µS (applies to a
single device)
• UL 94V-0 Flammability classification
ABSOLUTE MAXIMUM RATINGS @25˚C case temp
APPLICATION
(unless otherwise noted)
• Designed to protect sensitive electronics which operate
within an automotive system, such as: sound systems, satellite
navigation, climate control, engine management, stability
control, ABS etc.
