The ESD12VD3B is a bidirectional ESD protection diode designed for transient protection of 12V system ports. The device has a reverse standoff voltage of 8.0V and a minimum breakdown voltage of 8.5V to ensure stable blocking characteristics in harsh electrical environments.
Its diode capacitance as low as 120pF accurately adapts to the signal integrity requirements of industrial buses. Under the IEC 61000-4-5 standard surge test conditions, it can withstand 18A peak pulse current shocks while controlling the clamping voltage below 20V, providing efficient overvoltage event protection for industrial control systems.
The ESD protection performance exceeds ±30kV, fully meets the IEC 61000-4-2 standard certification, and has passed the AEC-Q101 automotive standard verification. It is suitable for automotive electronic control units, industrial PLC modules, communication base station power management and other fields that need to withstand high-energy transient shocks.
ESD12VD3B adopts the industry-standard SOD 323 package.
