LITTELFUSE SLD24-018

Silicon Avalanche Diodes
Axial Leaded High Power Automotive Transient Voltage Suppressors
RoHS
SLD Series
The SLD series is specifically designed for automotive
applications, available in both unidirectional and bidirectional.
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
APPLICATION
• 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.
Agency Approvals: Recognized under the Components
Program of Underwriters Laboratories.
Agency File Number: E128662
