DESCRIPTION
The Transky™ is designed specifically for portable equipments and miniaturized electronics devices subject to ESD transient overvoltages. The Transky™ combines the performance of a Transil™ or TVS (Tansient Voltage Supressor) and low forward voltage Schottky diode in a monolithic structure. COMPLIES WITH FOLLOWING STANDARDS IEC 61000-4-2 Level 4: 15kV (Air discharge) 8kV (Contact discharge) MIL Standard 883E-Method 3015-7: class 3C Human Body Model (HBM) Table 1: Order Code Part Number Marking SMTY18AM Y18 K A STmite (DO-216AA)
