Diodes - Zener - Single

The PZU27B,135 Zener Diode is a Single Zener Diode, which is a type of diode found primarily in electronic and electrical circuits. It has the capacity to regulate voltage by providing a high change in current in forward bias and low resistance in reverse bias states. It is also known as a voltage-regulating diode and is used to stabilise and control voltage levels in a wide range of electrical and electronics applications.

Application Field

The PZU27B,135 Zener Diode is used in a variety of applications, such as in TV, computer monitor and monitor power supplies, air conditioner and refrigerator power supplies, inverters, telecommunication system and other smart systems. It is also used in power conditioning and protector circuits and in the manufacturing of miniature motors and batteries. Furthermore, it is suitable for voltage regulation, voltage stabilisation or as circuit protection.

Working Principle

When the PZU27B,135 Zener Diode is connected in a circuit, current from the circuit flows through the diode. The diode is made of a special semiconductor material P-type and N-type, which allow it to regulate the current flow in both directions. If the current flowing through the Zener Diode is lower than the breakdown voltage (often known as the Zener voltage), then it is in Reverse Breakdown (RB) mode, where very low resistance is present, allowing the current to continue to flow through. However, If the current surpasses the Zener voltage, it will enter into Forward Bias mode, where a large change in current is immediately introduced to protect the components from being over-loaded.

The PZU27B,135 Zener Diode is suitable for applications with power supply voltages between 125V and 265V, and has a Maximum Voltage of 27V. This diode provides high surge current capability and comes in a DO-214AC SMB package. In addition, it has a Maximum Reverse Leakage Current of 1mA at Rated Voltage, with a Forward Voltage of 2V. Moreover, its Maximum Reverse Voltage Breakdown offers a high level of protection for protecting components in the circuit.

Conclusion

The PZU27B,135 Zener Diode is a single Zener Diode, and is ideal for use in applications such as voltage regulation, voltage stabilisation or as circuit protection. It is capable of regulating voltage and providing a high change in current in forward bias and a low resistance in reverse bias states, and has a maximum voltage of 27V, with reverse voltage breakdown of 1mA at rated voltage.
