The 2EZ91D5E3/TR8 diode is a single zener diode from the 2EZ91 series. This device provides a low forward voltage drop while providing a more reliable and efficient reverse voltage protection. It is suitable for a wide variety of applications including alternator and electronic displays, radio equipment, smoke detectors, power supplies, and microprocessors.

The 2EZ91D5E3/TR8 is characterized as a voltage-regulated device. It has a nominal zener voltage of 5V, but it can also handle reverse voltages up to 30V. It has a maximum tolerable power dissipation of 250mW, with a typical zener current of 2.5mA. When in a load switch off condition, its leakage current is less than 2mA.

In terms of its physical characteristics, the 2EZ91D5E3/TR8 has a size of 2.54x2.62mm, and is lead-free and RoHS compliant. It features a plastic matte black case, metal electrodes, and a transparent epoxy coating. This device has a maximum operating temperature of 80°C and a storage temperature range of -65°C to +150°C.

The 2EZ91D5E3/TR8 diode is typically used as an overvoltage protection device in circuit designs. Its main purpose is to protect electronics and sensitive components against damage caused by excessive voltage. It is suitable for a wide range of devices, including power supplies, displays, and radio equipment.

The working principle of this diode is based on its zener characteristics. When the diode is reverse biased, it will allow a certain amount of current to flow through it, up to a certain voltage. Once this voltage is reached, the diode will become a short circuit and the current will start to be blocked. This is how the 2EZ91D5E3/TR8 protects against overvoltage, effectively preventing any damage to the connected device.

In conclusion, the 2EZ91D5E3/TR8 is a single zener diode from the 2EZ91 series. It has a low forward voltage drop while providing reliable and efficient reverse voltage protection. It is characterized as a voltage-regulated device and is suitable for a wide range of applications. Its main purpose is to protect circuits and sensitive components against overvoltage by operating on the principle of zener characteristics.
