5.1V 1/2Watt Zener Diode

5.1V 1/2W Zener Diode for voltage regulation with 500mW power dissipation and ±5% tolerance.

The 5.1V 1/2Watt Zener Diode is designed to maintain a stable voltage output of 5.1V under reverse bias conditions. This diode is crucial for protecting sensitive electronic circuits from overvoltage, making it ideal for applications like voltage regulation and transient suppression. The compact axial lead package ensures easy integration into various circuits.

With a power rating of 0.5W and a tolerance of ±5%, the 5.1V 1/2Watt Zener Diode delivers reliable performance in voltage regulation circuits and reference voltage generators. Its maximum Zener current of approximately 49mA further enhances its capability in managing voltage spikes.

This diode finds extensive use in switching mode power supplies and overvoltage protection in DC systems. For those in Nashik, the DNA 5.1V 1/2Watt Zener Diode is available for purchase at our store or online with delivery options across India.
