The SMCJ350A-H is classified as a Transient Voltage Suppressor (TVS) diode designed to protect circuits and devices from over voltages. This component is used in a wide range of applications, including power supply systems, home entertainment systems, automotive electrical systems, and personal electronics. In general, TVS diodes provide surge current and electrostatic discharge (ESD) protection against voltage transients caused by lightning and other sources of disturbances.

The SMCJ350A-H is designed to work in both breakdown and clamping modes for effective protection of electronic devices. Its breakdown voltage is rated at 350 V while its clamping voltage is rated at 410 V. These ratings make it suitable for use in a variety of applications, such as protecting circuits from surges of up to 350 V and from ESD pulses of up to 410 V. The peak pulse current rating of this TVS diode is 28A.

The component is made up of two separate components within one package - the breakdown diode and the ESD protection diode. The breakdown diode is what provides the initial protection against overvoltage, while the ESD protection diode prevents damage caused by ESD pulses. The device is designed to operate with low capacitance and low capacitive loading, allowing it to protect circuits from fast turn-on/off transients as well. The device is also designed to work with a wide range of frequencies, so it has the flexibility to protect circuits from various types of electrical disturbances.

The SMCJ350A-H is well-suited for use in both automotive and consumer electronics applications, including in set-top boxes, LCD TVs, DVRs, digital cameras, and other consumer electronics products. In automotive applications, this device can be used to protect a variety of components, such as car audio systems, engine sensors, control modules, and electronic fuel injection systems. In all these applications, the SMCJ350A-H offers effective protection from damaging spikes, surges, and ESD pulses.

Overall, the SMCJ350A-H is an effective and reliable TVS diode with a wide range of use cases. It is well-suited for a variety of applications, both in automotive and consumer electronics, and is designed to operate reliably in both breakdown and clamping mode. Its high peak pulse current rating ensures it can protect circuits from a wide range of voltages, and its low capacitance means it can also offer protection from fast turn-on/off transients. In conclusion, the SMCJ350A-H is a great choice for a variety of applications where protection from overvoltages is required.
