1 RoHS Agency Approvals Agency Agency File Number 7596, 5659, 3 Description The of transient voltage surge suppressors are radial leaded 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 varistors are available in four model sizes: 7mm, mm, 4mm and 0mm; and have a V M(AC)RMS voltage range from 30V to 00V, and an energy absorption capability up to 360J. Some 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. See Device Ratings and Specifications Table for part number and brand information Features LR compliant option available. lease see the device and ratings specifications table for more information. voltage range V M(AC)RMS 30V to 00V 85ºC ambient capability (W TM ) up to 360J reel or bulk pack Absolute Maximum Ratings Continuous Units Steady State Applied Voltage: AC Voltage Range (V M(AC)RMS ) 30 to 00 V DC Voltage Range (V M(DC) ) 75 to V Transients: eak ulse Current (I TM ) For 8/0μs Current Wave (See Figure ) to 6 A Single ulse nergy Range For /00μs Current Wave (W TM ) to 360 J Operating Ambient Temperature Range (T A ) -55 to +85 O C Storage Temperature Range (T STG ) -55 to +5 O C Temperature Coefficient (a V ) of Clamping Voltage (V C ) at Specified Test Current <0.0 %/ O C Hi-ot ncapsulation (COATING Isolation Voltage Capability) (Dielectric must withstand indicated DC voltage for one minute per MIL-STD 0, Method 30) V COATING Insulation Resistance 00 MΩ CAUTION: Stresses above those listed in Absolute Maximum Ratings may cause permanent damage to the device.

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 in the diagram below. 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.
