Diodes - Zener - Single: JANTX1N4958D Application Field and Working Principle

The JANTX1N4958D diode is a part of the zener diode family. It is a single diode, intended for general purpose applications. It is a type of semiconductor diode that is designed to operate in the reverse voltage region, allowing current to flow in a controlled manner in the reverse direction. Zener diodes are used in many different applications, such as regulating voltages, stabilizing a voltage supply and providing a reference voltage.

Overview:

The JANTX1N4958D diode is a single diode, with a voltage range of 87 V to 92 V, rated at a 500 mW power dissipation (a rating that is also referred to as "thermal power"). It is a zener diode with a semiconductor chip, protected by an epoxy resin coating.The JANTX1N4958D diode has a maximum junction temperature rating of +150ºC, and a maximum Forward Continuous Current rating of 5 mA. The diode has a reverse breakdown voltage of 88.4 V, with a tolerances of ± 5%. The zener noise voltage is 5 μV at 1 KHz, and the maximum noise voltage is 30 μV.

Application Fields:

The JANTX1N4958D Zener Diode can be used in a variety of applications, such as:

• Regulating voltages in low power electrical circuits
• Stabilizing a voltage supply
• Providing a reference voltage
• Controlling an output voltage level
• Regulating an oscillator circuit
• Protecting circuit components from overvoltages

The JANTX1N4958D Zener Diode is used in many different types of electronic devices, including portable electronic devices, automotive electronics, and industrial electronics.

Working Principle:

The JANTX1N4958D diode is a zener diode, which means that it operates in the reverse bias region of a diode. In reverse bias, the diode is reversely biased and the applied voltage is greater than the breakdown voltage of the diode.A Zener diode is designed to conduct current in the reverse direction and maintain a constant voltage drop across the diode. The reverse bias voltage causes a voltage drop across the PN junction of the diode. This voltage drop is the Zener voltage and can be used to regulate the output of a circuit. The application of a forward bias voltage will cause the diode to become forward biased and act as a traditional semiconductor diode, allowing current to flow in the forward direction. In order for a zener diode to maintain a constant zener voltage drop, it must be operated in the reverse bias region.

Conclusion:

The JANTX1N4958D Zener Diode is a single diode, designed to operate in the reverse bias region. It is commonly used in many different types of applications, such as regulating voltages in low power electrical circuits, stabilizing a voltage supply, providing a reference voltage, controlling an output voltage level, and protecting circuit components from overvoltages. The Zener voltage drop across the PN junction of the diode is used to regulate the output of a circuit, and is maintained by operating the diode in the reverse bias region.
