BZX85C3V3 Silicon Planar Power Zener Diode

The BZX85C3V3 is a high-power silicon planar Zener diode designed for use in stabilizing and clipping circuits. It is part of the broader BZX85 series, which offers a wide range of Zener voltages graded according to the international E24 standard. This specific model provides a reliable 3.3V reference with a robust 1.3-Watt power rating, allowing it to handle higher currents than standard low-power Zener diodes like the BZX55 series. Housed in a hermetically sealed DO-41 glass package, the BZX85C3V3 is built for durability and long-term parameter stability, offering protection against junction contamination and environmental stress. It is commonly used as a low-voltage stabilizer or voltage reference in adapters, lighting applications, and on-board DC/DC converters. The cathode end is clearly marked with a color band for easy identification during circuit assembly.
