(Pack of 5) 12V 1W Zener Diode 1N4742A

(Pack of 5) 12V 1W Zener Diode 1N4742A 

The 1N4742A is a high-reliability 12V 1W Zener diode designed for stable voltage regulation in a wide range of electronic circuits. With a 1-watt power dissipation capability, it can handle higher current loads than 0.5W Zeners, making it suitable for medium-power power supplies, protection circuits, and precision reference applications. Housed in a DO-41 axial package, it offers excellent stability, low dynamic impedance, and long-term durability.
