BZX84C12-TP

Diodes - Zener - Single

The BZX84C12-TP is a zener diode that is designed to protect circuits from over-voltage. It allows a stable output voltage over a wide range of current, which is often used in voltage regulation systems. This particular diode is rated at 12 volts, with a rated current of 500 mA, and has a maximum power dissipation of 500 mW.

Application Field

Because of its ability to stabilize voltage in high-current applications, the BZX84C12-TP is commonly used in voltage regulator circuits. It is also used in audio power supplies, as their high rate of current can create a need for a stable output. This diode is also frequently used in various instrumentation applications, such as microphone preamps, as it can help to ensure accurate signal readings.

Working Principle

The working principle of a zener diode is based on the tunnel effect. When a forward-biased current is present and the voltage exceeds a certain threshold, electrons will tunnel through the diode and create a steady, stable output voltage. The BZX84C12-TP is designed to have a breakdown voltage of 12 volts, meaning that when this voltage is exceeded, a constant current will flow through the diode and output a steady 12 volts.

The zener diode works by providing a path of least resistance to the excess current, so that it doesn’t damage anything else in the circuit. This allows the diode to maintain a stable output voltage, even when higher current is present. It also makes it an ideal choice for voltage regulator circuits, as it will allow constant, stable output over a wide range of currents.

Conclusion

The BZX84C12-TP is ahighly popular diode, due to its ability to provide a stable output voltage over a wide range of currents. Its 12 volts breakdown voltage makes it ideal for use in voltage regulation circuits, as well as in audio power supplies and various instrumentation applications. The versatile design of this diode makes it a reliable choice for any circuit that needs stable, constant voltage.
