4.7V 1Watt Zener Diode 1N4732A

The 1N4732A is a 4.7V, 1W silicon planar Zener diode manufactured by Diodes Incorporated (as an alternative to onsemi and Vishay) for low-voltage power regulation and clamping. Housed in a hermetically sealed, axial-leaded DO-41 glass package, this discrete component provides a standard tight voltage tolerance of 5%. It operates at a nominal Zener breakdown voltage of 4.7V under a 53 mA test current while maintaining a maximum dynamic loop impedance of 8 ohms. Engineered for high reliability in power supplies, this robust device delivers stable electrical performance across a wide operating temperature range from minus 65 to plus 175 degrees Celsius.
