TVS - Diodes

About SMB10J6.5-E3/5B

TVS diodes, also known as Transient Voltage Suppression diodes, are components used to protect electronics from high-voltage transients. The SMB10J6.5-E3/5B is a popular transient voltage suppression (TVS) diode designed to protect sensitive electronics from high-energy transients. It is used in a variety of applications, including automotive, telecommunications, industrial, consumer electronics, military, and aerospace.

The SMB10J6.5-E3/5B diode features a low clamping voltage of 6.5KV and an operating temperature range of -55° to +125°. It is designed to protect against short and long transients, such as electrostatic discharge (ESD) and electrical fast transients (EFT). The device also features an operating current of 8A, a low capacitance of 10pF, and a very fast response time of less than 5ps.

Working Principle

The primary function of a TVS diode is to protect a circuit from electrical transients. Transients are high-voltage electrical spikes that can damage sensitive components, causing them to malfunction or fail. The diode acts as a surge protector, diverting the transient along a different current path that is isolated from the circuit.

The SMB10J6.5-E3/5B features a threshold of 6.5kV and can handle transients up to peak pulse power of 20KW. When an overvoltage condition is present, a small current is allowed to flow through the device, which is dissipated as heat. This amount of current and voltage depends on the type of circuit and the type of transient. When the transient passes, the diode will return to its original condition and the circuit will continue to operate as normal.

In addition to providing overvoltage protection, TVS diodes can also be used to filter out high-frequency noise and prevent interference from entering a circuit. This makes them ideal for use in sensitive electronics such as medical devices, measuring instruments, and communication equipment.

Conclusion

The SMB10J6.5-E3/5B TVS diode provides excellent protection for sensitive electronics from transient voltage spikes. It features a low clamping voltage, a fast response time, and can handle transients up to peak pulse power of 20KW. Additionally, it can be used to filter out high-frequency noise and interference. As such, it is widely used across a variety of industries, including automotive, telecommunications, industrial, consumer electronics, military, and aerospace.
