1N4740ATR Description

Short technical summary and product information.

The 1N4740ATR is a Zener diode from On Semiconductor designed for voltage regulation and clamping applications. It provides a nominal Zener voltage of 10V with a tolerance of ±5%, ensuring consistent performance within specified limits. The device is rated for a maximum power dissipation of 1W, making it suitable for low-power circuits.

 

Electrical characteristics include a maximum impedance (Zzt) of 7Ω and a reverse leakage current of 10µA at 7.6V. The operating temperature range spans from -65°C to 200°C, allowing use in harsh environments. The diode is packaged in a through-hole DO-41 (DO-204AL) axial leaded package, which facilitates easy insertion into printed circuit boards and prototyping.

 

Typical applications include voltage regulation, overvoltage protection, and reference voltage generation in analog and digital circuits. The robust construction and wide temperature range make it a reliable choice for industrial and consumer electronics.
