Diodes - Zener - Single

The MMSZ20T1 Stepping Zener diode is a low capacitance, medium voltage device suitable for drop-in replacements of discrete diode solutions. It has a breakdown voltage of 20V and has a wide range of application fields. The voltage is set by a combination of two Zener diodes, precision resistors and a capacitor. With its dynamic impedance, it can suppress the surge current in high-power systems and is stable under different environment conditions. It has an operating temperature range from -55 to +175 and is free of SOI technology.

The MMSZ20T1\'s working principle is based on two Zener diodes and a bypassed Q-arrangement. The Zener voltage is determined by the sum of the resistances and capacitance connected together. The bypass keeps the Zener voltage constant when a current is present and when it is constant, the diode can maintain its stability. The current is supplied through a voltage-controlled oscillator (VCO) circuit.

The MMSZ20T1 has a wide range of applications, such as AC-DC and DC-DC converters, automotive systems, linear power supply, portable power supply, and many others. It can perform voltage regulation, current limiting, and surge protection. It also has a low EMI emission, making it suitable for high-frequency applications. Its low capacitance also makes it suitable for high-speed designs.

In addition, the MMSZ20T1 can handle high reverse along with surge currents up to 100A. Its low turn-on voltage makes it suitable for applications requiring low voltage. This device is also suitable for automotive systems, linear power supplies, and other applications requiring low power dissipation.

The MMSZ20T1 is a reliable, low-cost product suitable for a wide variety of applications. It has a proven reliability and a long service life. Its high performance makes it suitable for automotive applications. With its wide range of applications, it is an ideal selection for a wide variety of applications.
