Overview
The ESD051-1F4 is a unidirectional single line TVS (Transient Voltage Suppressor) diode designed by STMicroelectronics to protect power lines against EOS (Electrical Overstress) and ESD (Electrostatic Discharge) transients. This component is particularly suited for applications where space-saving is crucial, such as in cellular handsets, wearable devices, USB buses, and battery lines. The ESD051-1F4 is packaged in the ST0201 package, which is environmentally compliant and available in various ECOPACK grades.
