TVS diodes are an important component of electronic circuits and printed circuit boards. They are used to protect sensitive electronic components, such as microcontrollers and memories, against transient surge voltages caused by electrostatic discharge or lightning. The TPSMP27AHM3_A/H is a Transient Voltage Suppressor Diode (TVS) device designed to protect sensitive electronic components from overvoltage transients, such as electrostatic discharge and lightning.

The TVS diode TPSMP27AHM3_A/H is a bidirectional, unidirectional, low capacitance, RoHS compliant surface mount device with excellent clamping performance, low reverse leakage current, and fast response time. It has an operating temperature range from -55°C to +150°C and a breakdown voltage of 27V. It is an ideal protection device for applications with sensitive electronic components.

The application field of the TPSMP27AHM3_A/H and its working principle are mainly related to transient voltage protection. It is used to protect microcontrollers, memories, and other ICs in electronic circuits from voltage spikes created by Electrostatic Discharge (ESD). The device contains two terminals: the positive and negative terminals. The positive and negative terminals must be connected to the circuit in opposite directions such that the current flows through the device in the direction of the arrow, as indicated on the label. When the voltage potential between the two terminals is higher than the Minimum Breakdown Voltage (V,BR), the device will turn on and act as a short circuit, limiting the amount of current that can flow through the circuit.

The TPSMP27AHM3_A/H can be used to protect against overvoltage transients generated by lightning strikes or elevated voltage potentials in the power line. When connected across the power lines, the TVS diode acts as a bidirectional clamp, helping to limit the voltage levels that can be applied to the microcontroller. This ensures that the voltage levels applied to the microcontroller do not exceed its rated operating voltage levels, helping to protect it from damage. It is also used to protect the power supply lines from unintentional ESD and voltage spikes.

The TPSMP27AHM3_A/H also works by responding quickly to a transient event, such as a sudden voltage spike from ESD or a lightning strike. It will clamp the voltage quickly and efficiently preventing further damage to the circuit. Additionally, it offers excellent clamping performance and low reverse leakage current.

In summary, the TPSMP27AHM3_A/H is an important component of electronic circuits and printed circuit boards. It is typically used to protect sensitive electronic components, such as microcontrollers and memories, against overvoltage transients caused by electrostatic discharge or lightning. The device offers excellent clamping performance, fast response time, and low reverse leakage current. It is used to protect the power supply lines and ensure that voltage levels do not exceed the rated operating voltage levels of microcontrollers.
