BZX79C12 Description

Short technical summary and product information.

The BZX79C12 is a 12V Zener diode from On Semiconductor designed for voltage regulation, clamping, and reference applications. It offers a nominal Zener voltage of 12V with ±5% tolerance and a maximum Zener impedance of 25Ω. The device can dissipate up to 500mW of power and operates over a wide temperature range from -65°C to 200°C.

 

Electrical characteristics include a forward voltage of 1.5V at 100mA and a reverse leakage current of 100nA at 8V reverse voltage. The diode is housed in a DO-35 axial leaded package (DO-204AH) with through-hole mounting, suitable for manual or wave soldering. The compact package allows for easy integration into low-power circuits.

 

This Zener diode is commonly used in voltage regulation, overvoltage protection, and as a voltage reference in analog circuits. Its robust operating temperature range qualifies it for industrial and automotive environments where stability is critical. Proper heat sinking should be considered when operating near maximum power dissipation.
