1N4751 Zener Diode 30V 1W

RWF 200

The 1N4751 Zener Diode is a 30V, 1W Zener diode designed for voltage regulation and protection applications. It allows current to flow normally in the forward direction, but in reverse, it maintains a stable voltage of 30V once the reverse voltage exceeds this threshold. With a power rating of 1 watt, it can handle moderate levels of energy dissipation, making it suitable for circuits where voltage stability is essential, such as in power supply regulation, signal conditioning, and protecting sensitive components from voltage spikes. Its robust construction ensures long-lasting performance in various electronic projects.
