2EZ43D/TR12 Datasheet/PDFThe 2EZ43D/TR12 diode is a single Zener diode with 5.6V breakdown voltage and a maximum power rating of 200mW. It is used in low voltage voltage regulation applications and protection against voltage transients. It has low dynamic impedance and low profile. It is suitable for mounting on PC boards.
Application
The 2EZ43D/TR12 diode is commonly used in power regulators, a wide range of low voltage protection applications, and in low power circuits. It is a good choice for voltage regulation in low current applications. It can be used in switch mode power supplies, electrical motor control circuits, motor drive circuits, surge protection, ESD protection, and power supply reset circuits. It is also used in reverse current protection, circuit protection for un-interruptible power supplies, and voltage clamping.
Working Principle
The 2EZ43D/TR12 diode operates on the principle of reverse biased zener breakdown. When the voltage applied to the diode exceeds the breakdown voltage (5.6V in the case of this diode), the diode conducts in a reverse direction. This allows current to flow in the reverse direction, and keeps the voltage across the diode at the breakdown voltage. This way, the voltage after the diode remains stable."
The 2EZ43D/TR12 diode is designed to operate with a maximum power rating of 200mW. This ensures that it can handle the current required to maintain the breakdown voltage. The low profile, low dynamic impedance and fast switching time of the 2EZ43D/TR12 makes it an ideal choice for low voltage applications where the circuit has to respond quickly to changes in the input voltage.
Conclusion
The 2EZ43D/TR12 diode is a single zener diode with a 5.6V breakdown voltage and a maximum power rating of 200mW. It is suitable for mounting on a PC board and is a good choice for low voltage voltage regulation applications and protection against voltage transients. Its low profile, low dynamic impedance and fast switching time make it a great choice for low power circuits.
