9.1V 0.5Watt Zener Diode 915-ZD

The 1N5239B is a 9.1V, 0.5W silicon planar Zener diode manufactured by Rectron for precise low-power voltage regulation and reference clamping. Housed in a hermetically sealed, through-hole DO-35 glass package, this discrete component ensures a standard tight breakdown voltage tolerance of 5%. It operates stably at a nominal Zener breakdown voltage of 9.1V under a 20 mA test current while presenting a maximum dynamic loop impedance of 10 ohms. Engineered for high reliability in compact board layouts, this robust device functions consistently throughout an operating temperature range from minus 65 to plus 175 degrees Celsius.
