The 1N4728A-T50A is a Zener diode from On Semiconductor designed for voltage regulation and reference applications. It features a nominal Zener voltage of 3.3V with a tolerance of ±5%, ensuring consistent performance in precision circuits. With a power dissipation rating of 1W, this diode can handle moderate power levels, making it suitable for a variety of power management tasks. The dynamic impedance (Zzt) is only 10 Ω, which provides good voltage regulation characteristics. The reverse leakage current is specified as 100 µA at 1V, indicating low leakage under reverse bias conditions. Operating temperature covers a wide range from -65°C to 200°C, allowing use in harsh environments. The device is available in a through-hole DO-204AL / DO-41 axial package, which is easy to mount on printed circuit boards using traditional soldering methods. This diode is RoHS3 compliant, REACH unaffected, and has MSL level 1 (unlimited), though these compliance claims are unverified. It is ideal for general-purpose voltage clamping, overvoltage protection, and as a reference element in linear regulators.
