A 1PMT4123C/TR13 belongs to a common semiconductor component referred to as a single Zener diode. A Zener diode is a specialized semiconductor structure that works inversely to the classic p-n junction diode. The 1PMT4123C/TR13 allows current to flow in the forward direction from the anode to cathode, and also allows reverse current from the cathode to anode when the voltage reaches a predetermined breakdown voltage. This type of diode is designed to dissipate the reverse current that flows when the voltage applied to the junction reaches the predetermined breakdown voltage.

The 1PMT4123C/TR13 is a small signal switching diode that features a very low forward breakover voltage, a low junction capacitance, and a low threshold voltage, making it a good choice for general-purpose switching applications.

The 1PMT4123C/TR13 is also a high-reliability diode designed for a wide range of low power applications, including ac and dc voltage regulation, current regulation, overload protection, and spike suppression. It is also used in applications such as buck and boost converters, motor drive applications, and general-purpose latching circuits.

The 1PMT4123C/TR13 has a breakdown voltage of 12 volts, making it suitable for many applications requiring reliability and current regulation. The diode is constructed of a special low-loss alloy junction and epoxy-encapsulated glass package that offers superior temperature and humidity robustness, making it ideal for a wide range of environments.

The working principle of 1PMT4123C/TR13 is relatively simple, but highly effective. When the current is applied to the diode, it begins to conduct and allow the current to readily flow. When this happens, the voltage across the diode increases, ultimately reaching the breakdown voltage level. At this point, the diode becomes increasingly non-linear, allowing current to flow in the reverse direction, effectively dissipating the current and preventing further damage.

Due to these features, the 1PMT4123C/TR13 is an ideal choice for a wide range of applications, notably in automated motor and relay control, overload protection, current regulation, voltage regulation, signal processing and general latching circuits. This diode is highly reliable and able to withstand a range of temperatures and operational environments.
