A diode is a common electronic component that plays an important role in electronic circuits. Temperature is an important factor that may affect the performance of diodes. Next, Haojinlong editor will discuss with you how temperature affects the performance of diodes. Firstly, temperature has an impact on the conduction characteristics of diodes. Generally speaking, when a diode operates normally at its rated temperature, it should have low on resistance and high on current.

Transient suppression diode, also known as TVS diode or transient suppression diode, is a widely used new type of high-efficiency circuit protection device. It has extremely fast response time (sub nanosecond level) and considerable surge absorption capability. When its two ends are subjected to a momentary high-energy impact, the TVS tube can quickly change the impedance value between the two ends from high impedance to low impedance, in order to absorb a momentary high current

TVS (Transient Voltage Suppressor) diodes and voltage regulators are commonly used components in the electronic field, each with unique advantages. The advantage of TVS diode is fast response time: The response time of TVS diode is usually in the picosecond level, which can quickly respond to transient voltage surges in the circuit and effectively protect sensitive components in the circuit.

TVS (Transient Voltage Suppressor) diodes and voltage regulators are important protective components in the electronic field, each suitable for different scenarios. Application scenarios of TVS diodes in automotive electronics: Voltage surges are a common phenomenon in automotive electronic systems, especially during engine start-up and shutdown. TVS diodes can effectively protect key components such as engine control units and sensors from damage caused by voltage surges.

TVS transient voltage suppression is achieved regardless of how the TV is generated, such as surges caused by direct or indirect lightning strikes, electrostatic discharge, large capacity load switching, and other factors The voltage ranges from a few volts to tens of kilovolts or even higher ESD electrostatic discharge protection here is mainly described by three models The main applications are HBM and MM.

Zener diodes and TVS diodes are both connected in reverse in the circuit, which utilizes their reverse characteristics and PN junction avalanche effect to have a critical voltage before reverse breakdown. They both have a stabilizing effect in reverse connected circuits, but they are not the same. Zener diodes use to fix the input voltage at a certain value, while TVS diodes mainly prevent transient high voltage from clamping the downstream circuit;
