1N4740A-T50A Description

Short technical summary and product information.

This 1N4740A-T50A Zener diode from On Semiconductor provides a nominal Zener voltage of 10V with ±5% tolerance. It is rated for a maximum power dissipation of 1W, making it suitable for voltage regulation and reference applications in low-to-medium power circuits. The device features a low maximum impedance of 7Ω at the Zener test current, ensuring stable voltage clamping. Reverse leakage current is specified as 10µA at 7.6V reverse voltage. The diode operates over a wide temperature range from -65°C to 200°C. It is housed in a standard DO-41 (DO-204AL) axial-lead through-hole package, compatible with automatic insertion and hand soldering. Typical applications include power supply regulation, overvoltage protection, and voltage reference circuits.
