Microchip Technology's 1N4909A is a voltage regulator diode designed for precise voltage referencing and regulation. This 400mW Zener diode features a nominal Zener voltage (Vz) of 12.8V with a tight tolerance of ±5%. Housed in a standard DO-7 (DO-204AA) axial package, it is suitable for through-hole mounting. The device offers a maximum Zener impedance (Zzt) of 50 Ohms at its rated current. With an operating temperature range of -55°C to 100°C, the 1N4909A is a robust component for applications in power supplies, voltage clamping circuits, and general voltage regulation across various industrial and consumer electronics sectors. It is supplied in bulk packaging.
