Constant Voltage Diodes (High Voltage Type)
UDZ LV Series
New high Zener voltage series ideal for
the automotive market
Product Outline
ROHM has recently expanded its constant voltage diode lineup to include the UDZ LV series of high voltage Zener
diodes designed to provide constant voltage protection in a variety of electronic circuits. 12 models are offered in a
range of Zener voltages (51V to 150V) for broad compatibility, including automotive ECUs. In addition, high surge
resistance makes them suitable for a range of applications, from consumer devices to automotive systems and
industrial equipment that demand superior reliability.
