BZT52A15-E3-18 application field and working principle

Introduction

BZX52A15-E3-18 (or BZT52A15-E3-18)is a Zener diode manufactured by Zetex Semiconductors. It is a single, overvoltage protector. Due to its very low impedance and current capabilities, it can be used in a wide range of applications, such as automotive electronics and consumer electronics. This Zener diode features a maximum DC power dissipation of 500mW and is available in either a DO-213AA or DO-213AB package. Typical applications include overvoltage protection, voltage limiters, pulsed power loads, and surge absorbers.

Application Field

The BZX52A15-E3-18 is suitable for a variety of applications such as automotive electronics, consumer electronics, and telecommunications. It is designed for use in overvoltage protection, voltage limiters, pulsed power loads, and surge absorbers. It is suitable for use in voltage regulation, overload protection, and power supply overvoltage protection circuits as well. It is also ideal as a crowbar or peak-pulsing circuit.

The BZX52A15-E3-18 is a suitable choice for use in low-power applications where high power handling and reverse power dissipation is not required. It is also suitable for use in very low-power applications or in high-voltage circuits where its low current characteristics are advantageous.

Working Principle

The BZX52A15-E3-18 operates in much the same way as any Zener diode. When the voltage across the diode exceeds the breakdown voltage of the device, it begins to conduct current. The amount of current that the diode conducts is determined by both the voltage across the device and the power rating of the device.

The BZX52A15-E3-18 has a breakdown voltage of 15V and is rated for a maximum DC power dissipation of 500mW. The BZX52A15-E3-18 also has a low impedance and current capabilities, which makes it suitable for a variety of applications. When the appropriate voltage is applied across the device, it will conduct current, limiting the voltage and protecting the device from overvoltages.

Conclusion

The BZX52A15-E3-18 is a single, overvoltage protector. It is designed for use in automotive electronics, consumer electronics, and telecommunications. It is suitable for use in voltage regulation, overload protection, and power supply overvoltage protection circuits. It can also be used in low-power applications where high power handling is not required and as a crowbar or peak-pulsing circuit. The device has a breakdown voltage of 15V and is rated for a maximum DC power dissipation of 500mW.
