Axial Leaded High Power Automotive Transient Voltage Suppressors
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.
