The BZD27C51P is a single Zener diode from Diodes Inc. It is designed to protect existing circuitry from excessive transients in the output voltage. BZD27C51P has an over-the-counter voltage of 27V and provides reverse dissipation of power at up to 500 mW. It has a peak reverse current of 100 μA, though it exhibits typical reverse leakage of 50 μA at 25°C.

The BZD27C51P is widely used in many types of electronic applications, including automotive systems and consumer electronics. For example, it is often used in overvoltage protection circuits, controlling or limiting the inrush current, and providing surge protection in automotive electronics. It is also used in line protection in communication systems, providing current-limiting/overvoltage protection and signal/power circuit protection that produce a stable operating voltage.

The working principle of a BZD27C51P is fairly simple. When the current reaches the overvoltage rating, the diode will shift its junction voltage to a constant voltage that is lower than the overvoltage voltage. This shift in the junction voltage will cause a decrease in the current, which will prevent further damage to the device and protect it from further high-power transients. The current will then stay in a constant level until its voltage drops below the breakdown voltage, or the minimum rated operating voltage.

The BZD27C51P is a small-sized single Zener diode that offers reliable protection from overvoltage transients. It can be used in numerous electronic applications, ranging from automotive systems and consumer electronics, to line protection in communication systems. Its simple working principle makes the diode an optimal choice for protecting sensitive circuitry from overvoltage transients.
