Varistor Products Radial Lead Varistors > LA series RoHS LA Varistor Series Description The LA Series of transient voltage surge suppressors are radial-lead varistors (MOVs) that are designed to be operated continuously across AC power lines. These UL recognized varistors require very little mounting space, and are offered in various standard lead form options. The LA Series varistors are available in four model sizes: 7mm, 10mm, 14mm and 20mm; and have a VM(AC) voltage range from 130V to 1000V, and an energy RMS absorption capability up to 360J. Some LA series model numbers are available with clamping voltage selections, designated by a model number suffix of either A or B. The `A' selection is the standard model; the `B' selection provides a lower clamping voltage. Agency Approvals Agency See LA Series Device Ratings and Specifications table for part number and brand information. Agency File Number E75961, E56529, E135010 Features 116895E t-FBEGSFFBOE3P)4 compliant option available. Please see the device and ratings specifications table for more information.

Varistor Products Radial Lead Varistors > LA series Power Dissipation Ratings Peak Pulse Current Test Waveform PERCENT OF PEAK VALUE Should transients occur in rapid succession, the average power dissipation is the energy (watt-seconds) per pulse times the number of pulses per second. The power so developed must be within the specifications shown on the Device Ratings and Specifications table for the specific device.The operating values of a MOV need to be derated at high temperatures as shown above. Because varistors only dissipate a relatively small amount of average power they are not suitable for repetitive applications that involve substantial amounts of average power dissipation. 100 90 50 10 O1 Current Energy and Power Derating Curve T TIME T1 T2 PERCENT OF RA TED VALUE 100 O1 = Virtual Origin of Wave T = Time From 10% to 90% of Peak T1 = Virtual Front '! +t T2 = Virtual Time to Half Value (Impulse Duration) Example: For an 8/20s Current Waveform: 8s = T1 = Virtual Front Time 20s = T2 = Virtual Time to Half Value 90 80 70 60 50 40 30 20 10 0 -55 50 60 70 80 90 100 110 120 AMBIENT TEMPERA TURE ( o C) LA Varistor Series Specifications are subject to change without notice. 130 140 150 44 Revised: January 15, 2008 www.littelfuse.com (c)2008 Littelfuse Varistor Products Radial Lead Varistors > LA series Transient V-I Characteristics Curves Pulse Rating Curves Maximum Clamping Voltage for 7mm Parts Repetetive Surge Capability for 7mm Parts t7-" 1 7-" 1 t7-" 1 7-" 1 2,000 6,000 5,000 1 MAXIMUM PEAK VOLTS (V) 3,000 2,000 V275LA2(P) V250LA2(P) 1,000 900 800 700 600 500 400 2 500 SURGE CURRENT (A) 4,000 V300LA2(P) 102 100 50 20 10 V150LA1(P) 2 V130LA1(P) 1 20 300 10-2 10-1 100 101 102 PEAK AMPERES (A) 103 103 104 105 106 10 200 5 200 10-3 MODEL SIZE 7mm V130LA1(P) - V480LA7(P) 1,000 MAXIMUM CLAMPING VOLTAGE MODEL SIZE 7mm 130 TO 300VM(AC) RATING TA = -55oC TO 85oC 104 INDEFINITE 100 1,000 IMPULSE DURATION ( s) 10,000 t7-" 1 7-" 1 4,000 3,000 MAXIMUM PEAK VOLTS (V) 2,000 MAXIMUM CLAMPING VOLTAGE MODEL SIZE 7mm 130 TO 300VM(AC) RATING TA = -55oC TO 85oC V300LA4(P) V275LA4(P) V250LA4(P) V230LA4(P) 1,000 900 800 700 600 500 400 300 V175LA2(P) V150LA2(P) V140LA2(P) V130LA2(P) 200 100 10-3 10-2 10-1 100 101 102 PEAK AMPERES (A) 103 104 MAXIMUM PEAK VOLTS (V) t7-" 1 7-" 1 MAXIMUM CLAMPING VOLTAGE 5,000 MODEL SIZE 7mm 320 TO 480VM(AC) RATING TA = -55oC TO 85oC 3,000 V460LA7(P) V480LA7(P) 2,000 1,000 V420LA7(P) V385LA7(P) V320LA7(P) 500 10-3 www.littelfuse.com (c)2008 Littelfuse 10-2 10-1 100 101 PEAK AMPERES (A) 102 103 104 45 Revised: January 15, 2008 LA Varistor Series Specifications are subject to change without notice.
