The SESD9D3V3 with Diodes - ESD SOD-923 RoHS manufactured by SINO-IC is a three-terminal electrostatic discharge (ESD) protection diode. It is used in electronic equipment and circuits to protect them from damage caused by electrostatic discharges. The diode is housed in an SOD-923 RoHS package and is suitable for use in SMD (Surface Mount Device) circuits. This component has a reverse voltage of 3.3V, a case operating temperature range of -55°C to +125°C, and a storage temperature range of -60°C to +150°C. It is a reliable protection device and is ideal for applications demanding fast response and low residual voltage.
