SHV Series- the main application is for surge protection for LED lighting.
According to the standard IEC61000-4-5, the requirements are 1.20x50us waveform (8x20us waveform) surge wave form, but some countries take different surge waveform as test standard.
Waveform & Impedance:
(1) 1.2x50us and 8x20us (combination)
2 ohm: usually used in power L-N (called line to line)
12 ohm: usually used in power L-N to PE (called line to ground)
1) Line to Ground (L-PE、N-PE ): it is Common Mode.
2) Line to Line (L-NL): it is Differential Mode. Schematic Circuit:
|Working Voltage||V(max)||Maximum continuous working voltage: within working temperature, the max. AC volt (RMS) loaded at both ends of component or DC voltage.|
|Breakdown Voltage||V(1mA)||At current (1mA), the terminal voltage of component, known as breakdown voltage.|
|Clamping Voltage||V(1A)||Loaded with standard current at waveform 8/20us, the maximum voltage of both ends|
|Surge Current||A||The allowed maximum pulse current through components (at 8x20μS)|
|Surge Voltage||A||The allowed maximum pulse voltage through components (at 1.2x50us)|
|Non-linear Coefficient (α)||To meet with I-V curve, I1 & I2, V1 & V2, α= log I2/ I1/ logV2/ V1.|
