ESD7351P2T5G

ESD7351P2T5G Description

The ESD7351P2T5G from onsemi is a unidirectional Zener-based TVS (Transient Voltage Suppression) diode designed for robust ESD (Electrostatic Discharge) protection in sensitive RF and high-frequency applications. Encapsulated in a compact SOD-923 package, this surface-mount device offers a 3.3V reverse standoff voltage (max) and a minimum breakdown voltage of 5V, making it ideal for safeguarding low-voltage circuits. With a capacitance of just 0.43pF @ 1MHz, it minimizes signal distortion, ensuring high signal integrity in RF antenna systems. Compliant with ROHS3 and REACH standards, it is suitable for environmentally conscious designs despite its obsolete status.
