(Pack of 5) 9.1V 1W 1N4739A Zener Diode

(Pack of 5) 9.1V 1W 1N4739A Zener Diode 

This pack includes five 9.1V 1W Zener diodes, commonly used for voltage regulation and protection in electronic circuits. These diodes maintain a stable 9.1-volt reference voltage when reverse-biased in the Zener breakdown region. They are widely used in low-power power supplies, reference circuits, and over-voltage protection applications. Typically supplied in a DO-41 axial package, they are suitable for DIY electronics, prototyping, and repair tasks.
