BYM4640_FDFS6N303-NL Introduction

Today I will introduce to you a domestic FET that is suitable for lithium battery protection boards and can replace MOS tubes such as AO3401: NCE3401.

So the stability of the tube is inseparable from the manufacturing process, and poor workmanship may result in the inconsistency of the parameters of these small tubes. Their various switching actions are almost the same. Of course, when they burn out, there must be a small tube that can't bear it first.

Felix Zandman experienced the Holocaust, lost loved ones, and lived in the dark underground for 17 months in the haze of death. The component industry and even the history of technological development have left a strong legacy. Today the physics book written by Dr. Felix Zandman is used as a basic textbook in many universities, and his autobiography has been translated into Chinese and many other languages. . In 2004 Fortune Magazine selected Vishay as one of America's more admired companies.

MOS tube 3306 product features 1. RDS(on)=7mΩ@VGS=10V 2. Lead-free green equipment 3. Low resistance switch to reduce conduction loss 4. High avalanche current.

There is parasitic capacitance between the three pins of the MOS tube, which is not what we need, but is caused by the limitation of the manufacturing process.

. For example, electronic fuel injection system, anti-lock brake control, anti-skid control, traction control, electronically controlled suspension, electronically controlled automatic transmission, electronic power steering, etc. The electronic device that can be used independently in the environment has no direct relationship with the performance of the car itself.

When the applied forward voltage increases, the concentration of unbalanced minority carriers increases and the concentration gradient also increases, and when the applied voltage decreases, the change is opposite. The process of charge accumulation and release in this phenomenon is the same as that of capacitor charging and discharging, which is called diffusion capacitance. Diffusion capacitance: When a forward voltage is applied, the non-equilibrium minority carrier concentration near the interface of the depletion layer is high, far from the non-equilibrium minority carrier concentration is low, and the concentration gradually decays from high to 0 until it reaches zero.
