Microchip Technology 1N3329A is a Zener diode designed for high-power voltage regulation applications. Featuring a nominal Zener voltage of 45V and a maximum power dissipation of 50W, this component offers robust performance. The diode exhibits a reverse leakage current of 10 µA at 32.7V and a maximum Zener impedance (Zzt) of 4.5 Ohms. Its ±10% tolerance ensures reliable voltage stabilization. The 1N3329A is housed in a compact DO-5 package, identified as DO-203AB, and supports chassis/stud mounting for efficient heat dissipation. It operates across a wide temperature range of -65°C to 175°C. The forward voltage (Vf) is a maximum of 1.5V at 10A. This device is suitable for use in power supplies, voltage clamping circuits, and other industrial control systems.
