Working Principle

The BZX55F7V5-TR Diode is a Zener diode, which is a type of diode that operates in the reverse-bias breakdown mode, allowing it to easily and effectively protect against over-voltage and over-current faults. When operating in reverse-bias mode, the diode acts as a voltage regulator, allowing current to flow in one direction (from source to load) and blocking current from flowing in the other direction. The reverse-bias breakdown mode is also known as Zener breakdown mode and is what gives this type of diode its voltage regulation capabilities. When used in power supply applications, the diode can help protect against short circuit and transient voltage faults, ensuring smooth operation of the power supply. The diode works by recognizing when the voltage surpasses a specified maximum limit and rapidly switching in order to divert current away from the protected components.

Conclusion

The BZX55F7V5-TR Diode is a single Zener diode designed to help protect against over-voltage and over-current fault conditions. It is well-suited to a wide range of applications, such as power management, telecommunications, automotive, consumer electronics and security systems. The device has a low breakdown voltage, wide operating temperature range, good avalanche capability and high peak power rating. The BZX55F7V5-TR Diode operates on the principle of reverse-bias breakdown, allowing it to act as an effective voltage regulator.
