ESDA8V2-1MX2 Unidirectional Diode

EOS and ESD Transil™ protection for chargers and battery ports from STMicroelectronics

STMicroelectronics ESDA8V2-1MX2 Unidirectional Diode STMicroelectronics' ESDA8V2-1MX2 is a unidirectional, single-line Transil diode designed specifically for the protection of integrated circuits in portable equipment and miniaturized electronic devices subject to EOS and ESD transient overvoltages. Designers of portable devices must improve internal protection against the risks presented by chargers of unknown quality. ST's ESDA8V2-1MX2 absorbs mains-borne surges containing up to 500 watts peak pulse energy, a level of protection that is 30 percent higher than the current most popular surge protector. At the same time, the ESDA8V2-1MX2 has 55 percent smaller footprint, measuring just 1.0mm x 1.45mm, thereby realizing space savings for designers to implement extra functions or further miniaturize the end product. This protection device also has a thinner profile of 0.55mm compared to 0.7mm or 1.0mm for typical alternative devices.
