[Original plan] Fast charging mobile phonevbusProtection case—SMD12CA SMD15CA SMD24CA
Smartphones are increasingly pursuing fast charging，The power is getting higher and higher，Not only does it have high requirements for charging adapters，righttype-cInterface is also a challenge，So the charging surge test for fast charging phones is becoming increasingly strict。
one、 SMD12CA SMD15CA SMD24CAThree anti-static devicesdiodePerformance advantages
These three materials are used asUSBinterfaceVbusCommon materials for electrostatic surge protection of power interface。The reasons for recommending these three are as follows：
l High power，Capable of withstanding large waves and surges，Such frequent occurrencesHot swappingIt can also protect internal circuits。Shanghai Leimao achieves 5500 in these modelsW-6000W(8/20us),relativeNexperia semtech litttefuse Brand'sDFN2020 series parameters are consistent，The single cost is only half。
l Flat-Clamp technology，Provide flat and temperature independent clamping voltage，Minimize the residual voltage of the protected system，This can better protect the downstream circuit，VCUltra low。
l Strong anti-static ability：Contact and air are both at 30KV
The following table lists the main parameters。
