ERZC20EK201Y Datasheet, PDF (1/6 Pages) Panasonic Semiconductor – ZNR Transient/Surge Absorbers

“ZNR” Transient/Surge Absorbers (Type E)
“ZNR” Transient/Surge Absorbers
Type : E
The ZNR Type E is capable of handling larger surge
energy than Type D in applications to protect electronic
equipment or semiconductor devices from switching and
induced lightning surges.
Features
● _{UL and CSA recognized components}
● _{Very large surge withstanding capability with a compact size}
● _{Direct mounting on boards like a power distribution board available}
● _{Fast response to steep impulse voltage}
● _{Low clamping voltage for better surge protection}
● _{RoHS compliant}
Recommended Applications
● _{Transistor, diode, IC, thyristor or triac semiconductor protection}
● _{Surge protection in industrial power plant operations}
● _{Relay or electromagnetic valve surge absorption}
● _{Surge absorption applications in broadcasting, communications devices, traffic/railroad, agricultural facilities, waterworks}
● _{Surge protection of automatic control devices for power distribution line}
