PPTC self-recovery fuse working principle and application precautions?         The working principle of PPTC self-recovery fuse is based on the positive temperature coefficient property of the material. Under normal working temperature, the fuse material is in a low resistance state; once the current exceeds the rated value, the internal temperature of the fuse increases, causing the material to enter a high resistance state, limiting current flow, preventing equipment damage or fire caused by overcurrent. However, once the current drops to a safe range, the internal temperature of the fuse decreases, the material returns to a low resistance state, restoring normal power state. PPTC self-recovery fuse application precautions are as follows: 1. Fully understand the working conditions of the protected circuit and select the appropriate fuse rated voltage and current values. 2. Avoid mechanical or other physical factors causing damage to the fuse, leading to failure or inability to self-recover. 3. During installation, avoid the fuse being in high-temperature environments or subjected to excessive vibration to prevent premature fuse failure or interference with self-recovery. 4. For fuses that need replacement, must select fuses with the same specifications and performance for replacement. 5. For infrequently used circuit equipment, regularly check the status and function of the fuse to ensure it can work normally when needed.

The TSS (Transient Suppressing Semiconductor) diode, also known as the TVS diode, is a passive electronic component used to protect electronic devices. It can limit the amplitude and slope of transient voltage spikes, thereby protecting other components in the circuit from voltage transients. The following is the working principle and application of the TSS diode:

The ESD (Electrostatic Discharge) diode is a passive electronic component used to protect electronic devices. It is also referred to as an ESD electrostatic protector. It can effectively limit the damage caused by electrostatic discharge (ESD) to circuits, preventing damage, malfunction, or failure caused by static electricity. The following provides a detailed explanation of the product characteristics and applications of the ESD diode:

What do EMS and EMI in EMC (Electromagnetic Compatibility) technology refer to respectively?

TVS diode (transient voltage suppressor diode) is a protective circuit commonly used to prevent sudden voltage increases or reverse voltage from affecting the circuit. It is a voltage regulation and protection component that can stabilize the voltage and convert excess voltage into heat or electrical energy for dissipation.
