The 1N4749A is a Zener diode from On Semiconductor designed for voltage regulation applications. It provides a nominal Zener voltage of 24V with a tolerance of ±5%, ensuring stable reference voltage in circuits. The diode can dissipate up to 1W of power, making it suitable for moderate power regulation tasks.
Electrical characteristics include a maximum impedance of 25Ω at the Zener test current and a reverse leakage current of 5µA at 18.2V. The device operates over a wide temperature range from -65°C to 200°C, allowing use in harsh environments.
The 1N4749A is offered in a DO-204AL (DO-41) axial lead package, designed for through-hole mounting. This package is widely used and easy to handle in prototyping and production.
The nominal Zener voltage is 24V.
The maximum power dissipation is 1W.
