15V 1Watt Zener Diode 1N4744A

The 1N4744A is a 15V, 1W silicon planar Zener diode manufactured by onsemi (and Vishay), designed for stable voltage regulation and overvoltage protection. Housed in a hermetically sealed, axial-leaded DO-41 glass package, this component offers a standard tight voltage tolerance of 5%. It operates at a nominal 15V under a 17 mA test current while maintaining a low maximum dynamic impedance of 14 ohms. Engineered for high reliability, it ensures long-term operational stability across a wide industrial temperature range from minus 65 to plus 200 degrees Celsius.
