BZT52C11-7

The BZT52C11-7 is a Zener controlled miniature SOD-80 silicon diode that offers high performance and reliability in a small form factor. It is a single-sized diode, with a unique reverse-biased voltage regulator that prevents the formation of excessive reverse-biased spikes when the voltage reaches its rated limit. This ensures safe and reliable operation of the device. It is used in a variety of applications including voltage regulation, power switching and protection, as well as in current limiting or squaring applications.

The BZT52C11-7 is designed to feature a Zener breakdown voltage of 11.7V. Beyond this level, the device suddenly drops the voltage and stops further increase. As a result, it provides a stable voltage for use at high currents and extreme temperatures. This feature makes it suitable for use in a wide range of high-power, industrial and automotive applications.

The working principle of the BZT52C11-7 is based on the avalanche breakdown effect of silicon. The device is designed to create a low-resistance region between two P-type and N-type junctions. When a sufficiently high voltage is applied, it is liberated due to the avalanche effect and the current is then limited to a safe level. The Zener breakdown voltage determines the exact current limiting point.

The BZT52C11-7 offers a wide range of features, including a low junction capacitance and an on-chip temperature sensor for monitoring junction temperature. The device also features an adjustable reverse breakdown voltage for fine tuning. It also includes temperature protection, current limiting and polarity protection for improved device reliability.

The BZT52C11-7 is ideal for applications where a reliable and safe voltage regulation is required. It is also suitable for AC/DC, voltage/current rectification, LED lighting, DC-DC conversion, power electronics, and more. The device is available in a variety of packages, with four different series from Zener, SOD-80, SOT-93 and SOT-223 to meet any application requirements.
