The 1PMT5938B/TR7 Zener diode is a single, low voltage Zener diode with a breakdown voltage of 7.5V. It is used to regulate the voltage in circuits that are exposed to higher voltages. This type of Zener diode is often used in power supplies, voltage regulators, and voltage protectors. The working principle of this diode is to limit the voltage to a certain value when the input voltage is higher than the particular set value. This voltage regulator is designed using a special internal design that allows it to function even at low applied voltages.
In terms of application, the 1PMT5938B/TR7 Zener diode is used for voltage regulation or voltage protection in electronic circuits, especially in power supplies or voltage Regulators. It could be used for voltage clamps for over voltage transient protection, for reverse bias operations, or for DC blocking or polarity protection. It could also be used to limit the amount of current that flows through the circuit, in order to improve its efficiency and protect the circuit from damage.
The working principle of the 1PMT5938B/TR7 Zener diode is based on the “Zener breakdown” phenomenon, which occurs when the reverse bias voltage applied to the diode exceeds the Zener breakdown voltage. When this occurs, the resistance across the diode suddenly drops to very low values (large current and virtually short circuit) and causes the diode to regulate the voltage across it to the specific breakdown voltage level, regardless of the input voltage.
The Zener breakdown voltage of 1PMT5938B/TR7 Zener diode is about 7.5V, whereas the power rating for the same is 200mW and the maximum reverse voltage rating is 7.5V. It is also designed to withstand a surge current of 1A as it can withstand a large current spike without being permanently damaged. As far as its maximum power dissipation is concerned, the 1PMT5938B/TR7 Zener diode is designed to dissipate up to 200mW of power. The maximum clamping voltage for this Zener diode is about 10V.
In conclusion, the 1PMT5938B/TR7 Zener diode is a single, low voltage Zener diode with a breakdown voltage of 7.5V. It is used to regulate the voltage in circuits that are exposed to higher voltages and has a power rating of 200mW as well as a maximum clamping voltage of 10V. It works on the principle of Zener breakdown and is used in power supplies, voltage regulators and voltage protectors.
