CMSZ5235B TR

The CMSZ5235B TR is a fully-trimmable single Zener diode in a 2-pin SOD-323 package. It is designed specifically for use in low-power, temperature related, precision voltage regulation applications. The CMSZ5235B TR is a two-terminal reverse breakdown voltage device with a continuous operating voltage rating of 5.3Volts. It features high power dissipation capability of up to 1W. It is also capable of operation in various environmental conditions with a maximum allowable surge current rating of up to 200mA without exceeding its specified thermal limits.

The CMSZ5235B TR is particularly suitable for use in equipment where power dissipation and temperature are of great importance, such as air conditioning, precision voltage regulation and temperature-sensitive electronic products. It can also be used in applications where temperature stability, low noise and a very low thermal resistance are required. It offers very high efficiency and reliability, making it an ideal choice for all these applications.

The working principle of the CMSZ5235B TR is simple. This diode conducts current only when the voltage applied to its anode is greater than its Zener voltage, usually referred to as the reverse break-down voltage. This means that when the supplied voltage is greater than the rated Zener voltage (5.3Volts) the current through the diode will flow, allowing for regulation of the load current. The load current should be within the rated current specifying for the diode and the capacitance should also be taken into account as it would affect the load’s impedance.

Moreover, the CMSZ5235B TR can be used in applications where the temperature of the environment or device is of great importance. It has an operation temperature rating of -55°C to +125°C, giving it a wide temperature range for operation. This makes it an ideal choice for a variety of temperature-sensitive applications for which it offers excellent thermal performance.

The CMSZ5235B TR is also designed with a wide range of features, such as a high-reliability construction, low power dissipation, and a wide reverse break-down voltage tolerance range of -30% to +30%. Additionally, it has a low leakage current, a low thermal resistance of 3°C/Watt, and a very low on-state voltage drop of 80mV at 10mA. This makes it suitable for applications with a very low quiescent current, such as touchscreens, displays, and frequency converters.

In conclusion, the CMSZ5235B TR is a highly reliable and efficient single Zener diode which is suitable for applications where low current dissipation and precision voltage regulation is needed. It offers a low thermal resistance and very low on-state voltage drop for better quiescent current and temperature stability. Moreover, its wide temperature range makes it suitable for use in applications that require temperature regulation.
