Introduction

The BZV49-C4V3,135 is a single zener diode which is used as either a voltage regulator or voltage stabilizer in electrical or electronic circuits.

Application Field

The BZV49-C4V3,135 is ideal for applications including voltage regulation of transistors, current regulation of light emitting diodes, and power protection circuits. This type of zener diode finds wide applications in switching power supply, switching regulators, linear voltage regulator circuits, line-splitting power supplies, battery chargers, and numerous other custom-designed circuits.

Working Principle

When reverse biased, the BZV49-C4V3,135 allows current to flow until the rated reverse breakdown voltage is reached. At this point, the current flows in a sharp avalanche breakdown within the diode, causing the voltage across the diode to drop. This voltage drop is determined by the zener rating, and is known as the zener voltage. The zener diode can be used to stabilize voltages and to protect circuits from overvoltage or transients.

The zener voltage is generated in an avalanche breakdown that occurs within the junction region. As the reverse applied voltage increases, the majority carriers will fall below the minimum energy gap, thus producing the avalanche effect. This increases the reverse current, resulting in a voltage drop across the junction. The voltage drop is stabilized by the circuit components, resulting in a stable voltage that does not depend on the current flowing through it. This is the basic principle of a zener diode.

Conclusion

The BZV49-C4V3, 135 diode is an important component in many electronic and electrical circuits. The diode utilizes the principle of the avalanche effect to provide voltage regulation, stabilization and protection against overvoltage or transients. This diode can be used in many applications, such as switching power supplies, switching regulators, linear voltage regulators, line-splitting power supplies, and battery chargers.
