(Pack of 5) 9.1V 1/2W Zener Diode

This pack includes five 9.1V Zener diodes rated at 0.5 watts (½W). These diodes are designed to operate in reverse breakdown mode, maintaining a stable 9.1V reference voltage. Their lower power rating compared to 1W Zeners makes them ideal for low-power voltage regulation and protection circuits in electronics projects, small devices, and signal conditioning applications. Typically, they come in a DO-35 axial lead package suitable for breadboards and compact PCB designs.
