WH Zener Diode SMD 12V BZT52C12 SOD123

The BZT52C12 is a 12V, 500mW surface-mount Zener diode manufactured by Microdiode Semiconductor (MDD) for voltage regulation, voltage clamping, and reference voltage applications. Housed in a compact surface-mount SOD-123 molded plastic package, this discrete component features a single diode configuration designed to optimize space in high-density circuit boards. It operates with a nominal Zener breakdown voltage of 12V and a maximum power dissipation of 500mW while carrying the package top-side marking code "WH". Engineered with low reverse leakage current, stable clamping performance, and a maximum forward voltage drop of 0.9V at a 10mA test current, this robust device delivers reliable performance across an operating junction temperature range from minus 65 to plus 150 degrees Celsius.
