The Zener Diode 1/4W series are through-hole voltage regulation diodes designed for electronic circuits requiring stable voltage reference or over-voltage protection. These diodes are ideal for power supply regulation, voltage clamping, protection circuits, and electronics projects. Available in a wide range of Zener voltages from 3V to 47V, they offer reliable performance for hobbyists, technicians, and industrial applications.

These diodes are through-hole mounted, making them compatible with breadboards, PCBs, and prototype boards. Their 1/4W power rating ensures stable operation in low-power circuits, while their compact size allows integration into compact electronic designs. BDTronics supplies high-quality Zener diodes in Bangladesh for electronics repair, circuit design, and DIY projects.
