TVS - Diodes: SMB10J6.5AHE3/52 application field and working principle

Transient Voltage Suppression (TVS) diodes, otherwise known as Silicon Avalanche Diodes, are devices designed to protect electronic components from destructive high voltage transients. They are designed to shunt the transients to the ground, effectively reducing the voltage on the circuit to a safe level. One of the most widely used TVS Diodes is the SMB10J6.5AHE3/52. This device is designed to protect against overvoltage transients with a peak pulse current as high as 10 amp and a peak pulse power of up to 100 watts.

Application Field

The SMB10J6.5AHE3/52 can be used in a variety of applications, including automotive electronics, industrial electronics, communications, and power supplies. It is designed to prevent costly damage to components from overvoltage transients caused by electrostatic discharge (ESD), inductive switching, and surge events. This device is also compliant with the Directive 2011/65/EU, also known as the RoHS Directive, which restricts the use of certain hazardous substances in electrical and electronic products.

The SMB10J6.5AHE3/52 provides reliable protection for a wide range of power supplies and equipment. It is ideal for protecting sensitive electronics from voltage spikes and can be used in situations where multiple protection stages are needed. The device can be used in both AC and DC applications, making it an ideal choice for a wide range of industrial and consumer electronics.

Working Principle

The working principle of the SMB10J6.5AHE3/52 is based on avalanche breakdown. When an overvoltage transient is applied to the device, the diode junction breaks down and the current is diverted to the ground, thus limiting the voltage to a safe level. The device also features a low dynamic resistance, which ensures a fast response to high voltage transients.

The SMB10J6.5AHE3/52 is designed to remain in an off state until a voltage exceeds the breakdown voltage. When this occurs, the diode begins to conduct and the excess current is diverted to the ground. This allows the device to limit the voltage presented to the protected component to a safe level, thus preventing costly damage.

The device\'s plastic case ensures that it is able to withstand high voltages, while its low capacitance ensures a fast response to transients. This makes it an ideal choice for a wide range of industrial and consumer electronics applications.

Conclusion

The SMB10J6.5AHE3/52 is a highly reliable TVS diode designed to protect sensitive electronic components from destructive overvoltage transients. It is designed to shunt the transients to the ground, quickly limiting the voltage presented to the protected component to a safe level. This device is RoHS compliant and is ideal for use in a variety of applications, including automotive electronics, industrial electronics, communications, and power supplies.
