The 1N4681 TR belongs to the category of semiconductor devices, specifically zener diodes.
It is commonly used for voltage regulation and protection in electronic circuits.
The 1N4681 TR is typically available in bulk packaging or tape and reel, with quantities varying based on supplier specifications.
The 1N4681 TR has a standard DO-41 package with two leads. The anode is connected to the positive terminal, while the cathode is connected to the negative terminal.
The 1N4681 TR operates as a voltage regulator by allowing current to flow in the forward direction when the voltage is above the specified zener voltage, effectively clamping the voltage at the zener voltage level.
When the voltage across the 1N4681 TR exceeds its zener voltage, it begins conducting in the reverse direction, effectively maintaining a constant voltage drop across its terminals.
The 1N4681 TR is widely used in various electronic circuits such as voltage regulators, overvoltage protection circuits, and power supplies where precise voltage regulation is required.
Some alternative models to the 1N4681 TR include: - 1N4728A (3.3V zener voltage, 1W power dissipation) - BZX84C3V3 (3.3V zener voltage, 250mW power dissipation) - MMBZ5221B (3.3V zener voltage, 350mW power dissipation)
In conclusion, the 1N4681 TR zener diode provides precise voltage regulation and protection in electronic circuits, making it a crucial component in various applications.
