(Pack of 5) 5.1V 1/2W Zener Diode
This pack includes five 5.1V Zener diodes rated at 0.5W (½ watt). These diodes are designed to operate in the reverse breakdown region, providing a stable 5.1V reference voltage. They are ideal for low-power voltage regulation, signal protection, and reference circuits. Typically supplied in a DO-35 axial package, they are easy to use on breadboards and compact PCBs.
