TVS - Diodes are transistor-based components used to provide electrical overvoltage protection. The SMBJ6.5AHM4G is a unidirectional, dual, overvoltage suppressor diode designed primarily to protect components from transient voltage events.

It contains two element junctions in a single package with asymmetrical breakdown voltage characteristics. It is suitable for protecting any component or circuit from transients generated by inductive loads. The SMBJ6.5AHM4G is configured to trigger when the voltage exceeds a double peak voltage of 6.5 Volts.

The diode\'s applications include both on-board and off-board protection of modern electronics components from overvoltage-related failures. In addition, it provides a low capacitance solution to surge protection from ground bounce or short pulses. It is designed to provide protection for digital and analog signal lines and is especially well-suited for ESD protection.

The SMBJ6.5AHM4G operates by diverting voltages or current away from sensitive components when the voltage exceeds a predetermined threshold. The device voltage clamping action reduces the voltage across the component to a safe level. The component also has a low parasitic capacitance of 1.5pF for easy signal integrity.

The working principle of this TVS diode is simple and efficient. When an overvoltage is applied across the terminals, the voltage will increase until the breakdown voltage is reached, after which the diode will switch on. After the diode is turned on, the voltage will remain clamped at its breakdown level until the current decreases to a safe level.

The SMBJ6.5AHM4G is a robust protection solution in high speed digital designs. It is available in the SOT-323 surface-mount package and is RoHS compliant. It is rated for operating temperature of -55°C to 125°C and is designed to handle peak pulse power of 2.3 watts per line (1ms @ 8.3A). The maximum reverse leakage current is 50uA and the minimum breakdown voltage is 6.5V.

The SMBJ6.5AHM4G provides a cost-effective protection solution for a wide variety of applications where overvoltage transients are likely to occur. Its low parasitic capacitance and robust design make it perfect for ESD protection and other surge protection applications.
