3.3V 1Watt Zener Diode 3V3 1n4728a

The 1N4728A is a 3.3V, 1W silicon planar Zener diode manufactured by onsemi, engineered for precise low-voltage regulation and threshold switching circuits. Housed in a hermetically sealed, axial-leaded DO-41 glass package, this component offers a standard 5% voltage tolerance and high reliability. It operates at a nominal Zener voltage of 3.3V under a 76 mA test current, maintaining a maximum dynamic impedance of 10 ohms. Its robust construction ensures long-term operational stability across a wide temperature range from minus 65 to plus 200 degrees Celsius.
