Can a voltage regulator diode replace a TVS to protect a USB interface?

Voltage regulator diodes (Zener Diodes) and transient voltage suppressors (TVS), also known as transient voltage suppression diodes or transient suppressor diodes, each have their own applications in circuit protection.

Let's discuss whether a voltage regulator diode can replace a TVS to protect a USB interface:

No, it cannot. Voltage regulator diodes and TVS serve different functions and are applicable in different scenarios for circuit protection. Voltage regulator diodes are primarily used to stabilize voltage, whereas TVS is used to protect circuits from transient overvoltage damage.

USB interfaces are common interfaces in electronic devices and may face threats from various transient overvoltages in the external environment. These transient overvoltages can potentially damage circuit components within the USB interface. Therefore, specialized transient overvoltage protection devices like TVS are needed to protect USB interfaces.

While voltage regulator diodes can limit voltage rise, they have slower response times and cannot promptly respond to transient overvoltages. Additionally, the power and voltage range of voltage regulator diodes may not meet the requirements for protecting USB interfaces.

Therefore, voltage regulator diodes cannot replace TVS to protect USB interfaces. When designing protection circuits for USB interfaces, appropriate TVS or other transient overvoltage protection devices should be selected to ensure circuit safety and stability.
