Diodes-Zener-Single refers to diodes which use the Zener breakdown voltage phenomenon to provide reverse voltage protection and voltage regulation in regulated circuits. One specific example of a product within this category is the DDZX6V2B-13, which is used for surge protection and voltage regulation in electronic applications. This article details the uses and working principles of this device.

DDZX6V2B-13 Application Field

The DDZX6V2B-13 is a 6V Zener diode packaged in a SOD-323 package. This diode is intended to be used in consumer and professional electronics, particularly when there need to be circuit protection from overvoltage and as a voltage regulator in regulated power supplies. Specifically, the DDZX6V2B-13 can be used for protection in electronic systems such as USB power adapters and portable electronic devices. It is also used in power switching and to regulate the output voltage in the bridge of low power converters, such as DC-DC converters.

DDZX6V2B-13 Working Principle

At its core, the DDZX6V2B-13 is a Zener diode which uses the Zener breakdown phenomenon to provide reverse voltage protection and voltage regulation. Zener breakdown occurs when the reverse bias voltage exceeds a certain threshold. When this occurs, an avalanche will occur, which is a rapid increase in the reverse current. This avalanche acts similarly to a protective circuit breaker, as it will cause the voltage to immediately drop to a safe level, protecting the circuit from overvoltage.

The DDZX6V2B-13 also has a built-in voltage regulator, which uses the principle of Zener breakdown to maintain the output voltage. When the current passing through the diode increases, so does the voltage drop across the diode, allowing the voltage to be accurately regulated to a certain value.

Conclusion

The DDZX6V2B-13 is a Zener diode that is used for voltage regulation in regulated power supplies, surge protection, and other applications. Its functioning comes from the Zener breakdown phenomenon, which is used to create a sudden drop in the output voltage. This sudden drop in the output voltage acts to protect the circuit from overvoltage, and to regulate the voltage effectively to the desired level.
