Glass Encapsulated TransGuard® GENERAL DESCRIPTION The Glass Encapsulated TransGuard® multilayer varistors are zinc oxide (ZnO) based ceramic semiconductor devices with non-linear, bi-directional V-I characteristics. They have the advantage of offering bi-directional overvoltage protection as well as EMI/RFI attenuation in a single SMT package. These large case size parts extend TransGuard range into high energy applications. In addition the glass encapsulation provides enhanced resistance against harsh environment or process such as acidic environment, salts or chlorite flux. GENERAL CHARACTERISTICS Operating Temperature: -55ºC to 125ºC FEATURES APPLICATIONS • Bi-Directional protection • EMI/RFI attenuation in off-state • Multi-strike capability • Sub 1nS response to ESD strike • High energy / High current • Glass Encapsulated • Proffesional / Industrial / Commercial Applications • IC Protection, DC motor protection • Relays, Controllers, Sensors • Smart Grids • Alarms and more • Various Applications where Glass Encapsulation is Needed for Harsh Environment / Acid-Resistance HOW TO ORDER V G 1812 16 P 400 Varistor Glass Encapsulate Chip Chip Size Working Voltage Engergy Rating Clamping Voltage 16 = 16Vdc 22 = 22Vdc 38 = 38Vdc 65 = 65Vdc S = 2.0J P = 2.7-3.0J U = 4.0-5.0J Y = 7.2-12J 400 = 42V 440 = 44V 770 = 77V 131 = 135V 1210 1812 2220 R P Package Termination D = 7" reel R = 7" reel T = 13" reel P = Ni/Sn plated PHYSICAL DIMENSIONS: mm (inches) Size (EIA) 1210 1812 2220 Length (L) 3.20±0.20 (0.126±0.008) 4.50±0.30 (0.177±0.012) 5.70±0.40 (0.224±0.016) Width (W) 2.49±0.20 (0.098±0.008) 3.20±0.30 (0.126±0.012) 5.00±0.40 (0.197±0.016) Max Thickness (T) 1.70 (0.067) 2.00 (0.079) 2.50 (0.098) Land Length (t) 0.14 max.
