Diodes - Zener - Single

The BZT52C43K RKG is a single zener diode that is a great choice for any circuit project requiring reverse voltage protection. It is small and versatile, making it suitable for a range of applications. It offers protection against reverse voltage spikes and surges, as well as other problems related to high voltage transients. The BZT52C43K RKG is one of the most reliable and widely-used zener diodes available, and it provides a great overall value for circuitry needs.

Application Field

The BZT52C43K RKG is designed for use in circuits that require reverse voltage protection, as well as for noise suppression, power supply regulation, and other high-voltage related applications. It is particularly well suited for use in automotive circuitry, where reverse voltage protection is critical. Additionally, it can be used in motor drives, HVAC systems, and electrical control circuits. The BZT52C43K RKG is available in both surface mount and through-hole packages to meet different space requirements.

Working Principle

The BZT52C43K RKG operates as a single zener diode. The diode is constructed with two electrodes, one anode (positive end) and one cathode (negative end). When a reverse voltage is applied, the diode will “break-down”, allowing current to flow from the negative to the positive end, thus protecting the circuit from further damage. This “breakdown” voltage is known as the Zener Voltage, which is nominally set to 43V in the BZT52C43K RKG.The BZT52C43K RKG is capable of withstanding high reverse voltage spikes, up to 500V. This is extremely beneficial in applications that require surge protection. Additionally, the very low dynamic resistance ensures low signal loss and low noise emissions, making it suitable for use in signal conditioning circuits. The BZT52C43K RKG is rated for current handling up to 200mA, and its high thermal capacity ensures that it can handle large current spikes without any issue. It also has a Polarity Reversal Protection feature, meaning that if an incorrect polarity is applied it will allow for a safe reverse flow of current to protect the circuit.

Conclusion

The BZT52C43K RKG is an excellent choice for any application that requires reverse voltage protection. It is versatile, reliable, and cost effective, making it a great value for the money. Additionally, its wide range of features and levels of protection make it a great choice for a variety of applications. Whether you’re looking for reverse voltage protection, noise suppression, power regulation, or signal conditioning, the BZT52C43K RKG is a great choice.
