TVS - Diodes and the SZNUP2125WTT3G

TVS-Diodes, also known as Transient Voltage Suppressors (TVSs) or Transient Voltage Suppression Diodes, are semiconductor components that are designed to protect sensitive electrical and electronic components from voltage or current transients. They are often used in power supplies, data transmission systems, and electrical equipment where transient voltages need to be quickly reduced to safe levels. The SZNUP2125WTT3G is a TVS-Diode that is specially designed for automotive applications.

SZNUP2125WTT3G Features and Specifications

The SZNUP2125WTT3G is an automotive-grade unidirectional, 12V TVS-Diode that is designed to withstand transients up to 15V (peak). It is packaged in a surface mount small package (3 x 1.25mm) and offers a minimum peak pulse power rating of 21A. It also features a high clamping voltage of 20V, a low capacitance of 1.5pF, and excellent surge absorption performance.

SZNUP2125WTT3G Application Fields

The SZNUP2125WTT3G is most commonly used in automotive applications where its small package size and fast response make it ideal for use in power supplies, ignition systems, fuel injection systems, and electronic control units. It can also be used in industrial environments and other applications that require fast response time and high surge absorption.

SZNUP2125WTT3G Working Principle

When a transient voltage or current spikes above its rated levels, the SZNUP2125WTT3G begins to conduct, effectively clamping the voltage. The diode conducts until the transient subsides, and then it quickly turns off. This process is repeated until the operation is successful and the equipment is protected.The SZNUP2125WTT3G is an ideal choice for automotive applications that require a fast response time, high surge absorption, and a small package size. It can also be used in industrial applications where fast response time and high surge absorption are critical.
