This peak current is the maximum peak current at which the nominal varistor voltage shift dose not exceed ±10% when the test impulse is applied twice at a 5 minute interval. 4 * Nominal varistor voltage: Vnom Indicates the varistor terminal voltage measured with 1mA DC applied. 05A type 0.1mA DC *5 Maximum clamping voltage: Vc Indicates the peak terminal voltage measured with 8/20µs impulse current applied. *1 The waveform of the maximum DC applied voltage is flat. When a ripple voltage as from a rectifier source is applied, make sure that the peak voltage is within the Vdcm rating. The AC applied voltage (50/60Hz) is a sine waveform. When waveform distortion is extensive, make sure that the peak voltage is less than 2 times the Vacm rating. 2 * Energy Wtm Transient energy rating are given in the Wtm column in Joules (Wattsecond). The rating is the maximum allowable energy of a single 2ms square-waveform impulse current continuously applied. Energy ratings are based on a shift of Vnom of less than ±10% of the initial value. 1 FUJI Ceramic Surge Absorbers Characteristic curves (Typical) Transient V-I characteristic curves 2000 (ENF221D05A to ENF471D05A) Z-TRAP ENF series 220 to 680V (Varistor voltage) Max. idle current Max. clamping voltage ENF471D05A 1000 900 800 700 600 500 400 ENF271D05A ENF241D05A ENF221D05A A 71D05 ENF4 Voltage [V] 300 200 A 71D05 ENF2 A 41D05 ENF2 05A 1D ENF22 100 90 80 70 60 50 40 -6 10 10 -5 10 -4 10 -3 10 -2 10 -1 10 0 10 1 10 2 700 Current [A] Transient V-I characteristic curves 2000 (ENF221D07A to ENF471D07A) Max. clamping voltage ENF471D07A Max. idle current 1000 900 800 700 600 500 400 ENF271D07A ENF241D07A ENF221D07A Voltage [V] 1D07A ENF47 300 200 D07A ENF271 1D07A ENF24 D07A F2 EN 21 www.DataSheet4U.com 100 90 80 70 60 50 40 -6 10 10 -5 10 -4 10 -3 10 -2 10 -1 10 0 10 1 10 2 10 3 1350 Current [A] Transient V-I characteristics curve 2000 (ENF221D10A to ENF471D10A) Max idle current Max. clamping voltage ENF471D10A 1000 900 800 700 600 ENF271D10A ENF241D10A ENF221D10A Voltage [V] 500 400 300 A 71D10 ENF2 0A 41D1 ENF2 0A 1 21D ENF2 A 71D10 ENF4 200 100 -6 10 10 -5 10 -4 10 -3 10 -2 10 -1 10 0 10 1 10 2 10 3 2750 Current [A] 2 FUJI Ceramic Surge Absorbers Z-TRAP ENF series 220 to 680V (Varistor voltage) Transient V-I characteristic curves 5000 4000 3000 (ENF511D10A to ENF681D10A) Max. idle current Max. clamping voltage 2000 ENF681D10A ENF621D10A Voltage [V] ENF511D10A 1000 900 800 700 600 500 400 300 ENF511D10A ENF621D10A ENF681D10A 200 10 -6 10 -5 10 -4 10 -3 10 -2 10 -1 10 0 10 1 10 2 10 3 2500 Current [A] Transient V-I characteristic curves 2000 (ENF221D14A to ENF471D14A) Max. idle current Max. clamping voltage ENF471D14A 1000 900 800 700 600 500 400 Voltage [V] 300 200 14A 471D ENF ENF271D14A ENF241.
