Diodes - Zener - Single

The SZMMSZ24T1G is a single Zener diode that was designed for protection circuit designs for automotive applications. Its main role is to provide a stable voltage reference for voltage regulation circuits. The SZMMSZ24T1G has a wide temperature range for operating as an active element in temperature compensation circuits. It also has a low static current due to its small junction capacitance.

Application Field

The SZMMSZ24T1G is suitable for numerous applications including voltage clamping, voltage referencing, current limiting, reverse battery protection, load protection, and load switching applications. Because of its low leakage current, the SZMMSZ24T1G can be used in battery operated systems as a way to conserve battery life. Additionally, as a temperature-compensated Zener diode, it can be used in temperature sensitive applications like thermocouple measurements, thermistor measurements, bridge circuit, amplifier stability circuits, preamplifier circuits, and temperature detecting devices.

Working Principle

The main working principle of a Zener diode is based on avalanche breakdown effect. When the Zener diode is forward-biased, it behaves like a normal silicon diode. As the forward voltage is increased, the current is increased proportionally. Once the applied voltage reaches the breakdown voltage, the diode begins to conduct in the reverse direction and the voltage across the diode stays constant at a constant voltage level, regardless of the magnitude of the current. This process is known as Zener breakdown and this is the principle that the SZMMSZ24T1G works on.

The SZMMSZ24T1G is optimized for low maximum Zener voltage (VZ) and maximum reverse leakage current (IR), while providing a safe operating area (SOA) and other electrical characteristics. The SZMMSZ24T1G can be used in a variety of automotive forms to provide a stabilized voltage reference necessary for the proper functioning of any associated devices.

Conclusion

The SZMMSZ24T1G single Zener diode is specifically designed for protection circuit designs for automotive applications. It provides a stable voltage reference for voltage regulation circuits and its wide temperature range makes it suitable for a variety of temperature sensitive applications. The main working principle of the SZMMSZ24T1G is based on the avalanche breakdown effect, and its low leakage current allows it to be used in battery operated systems.
