The TFZV15B is a Zener diode featuring a Zener voltage of approximately 15V. It is built to handle specific reverse current levels without sustaining damage, shielding components from voltage surges. Details regarding forward voltage, reverse current, and power dissipation vary based on the model specifications from the manufacturer.

This diode is used where a reliable voltage reference is crucial, such as in voltage regulators. It also protects vulnerable components from overvoltage situations by conducting and redirecting surplus current when voltage surpasses the Zener voltage. In clipping applications, the Zener diode confines voltage to a set point, preventing signal overshoot beyond a defined boundary.
