Introduction

2EZ24D2/TR8 is a diode from the Zener single series – part of the range of diodes offered by semiconductor manufacturer Texas Instruments. The 2EZ24D2/TR8 is a type of planar, double-diffused silicon, PN-junction device, which functions as a voltage regulator.

Application Field

The 2EZ24D2/TR8 is mainly used in any application where a low-voltage Zener diode is required. It is best suited to applications where low voltage drop, temperature coefficient of current, power dissipation, capacitance, and reverse currents are critical.The most common application for the 2EZ24D2/TR8 includes in DC-DC switching regulaters, AC-DC power supplies, portable devices and any system that requires a low-voltage voltage regulator. It is also used in supplying electrical power to electronic chips, automotive panels, and controlling circuits.

Working Principle

While under normal operating conditions, the 2EZ24D2/TR8 acts as a conventional diode, enabling current to flow from the anode terminal to the cathode terminal. When the reverse bias voltage is applied to the diode, it enters the Zener region - allowing current to travel from the cathode to the anode.To better understand how the 2EZ24D2/TR8 works, it is useful to look at the internal structure of the diode. The 2EZ24D2/TR8 is made up of several layers of heavily doped silicon, which form a P-N junction.When the diode is forward-biased, current flows from the anode to the cathode. This is due to the voltage drop across the PN junction, which allows it to act as a conventional diode. When the reverse bias voltage is applied, electron-hole pairs form, which increases the voltage drop across the PN junction. This is known as avalanche breakdown, which causes the diode to enter the Zener region.The Zener effect occurs when a reverse bias voltage is applied to the diode, which causes the diode to act as a resistor – allowing current to travel from the cathode to the anode. If the reverse bias voltage is too large, it will cause the diode to break down, destroying the device in the process. However, if the reverse bias voltage is kept below the breakdown voltage, the 2EZ24D2/TR8 can be used to regulate the voltage in the circuit.As far as the current rating of the 2EZ24D2/TR8 goes, it has a peak forward current rating of 1A, with a typical Zener voltage of 6.5V and a pulldown voltage of 6.2V. It also has a reverse leakage current of 1mA and an operating temperature range of -55 degrees to +125 degrees Celsius.

Conclusion

In conclusion, the 2EZ24D2/TR8 is a low-voltage Zener diode supplied by Texas Instruments. The 2EZ24D2/TR8 is mainly used in any application that requires a low-voltage voltage regulator, such as in DC-DC switching regulaters, AC-DC power supplies, portable devices and any system that requires a low-voltage voltage regulator. It has a peak forward current rating of 1A, along with a typical Zener voltage of 6.5V, a pulldown voltage of 6.2V, and a reverse leakage current of 1mA. The 2EZ24D2/TR8 works by allowing current to flow from the anode to the cathode when under normal operating conditions, and allowing current to travel from the cathode to the anode when the reverse bias voltage is applied.
