FAQ

What is the nominal Zener voltage of this diode and why does it matter?

The nominal Zener voltage is 12 volts, which is critical for applications requiring precise voltage regulation. This voltage defines the point at which the diode breaks down and maintains a stable voltage, protecting circuits from overvoltage conditions and ensuring consistent performance.

How does the power dissipation rating affect the diode??s application?

With a power dissipation rating of 5 watts, this diode can handle relatively high power levels without overheating or failing. This makes it suitable for applications where significant current may flow through the diode during voltage regulation or protection, enhancing overall circuit reliability.

What package type is used and what are its benefits?

The diode is housed in a DO-41 glass package, which offers hermetic sealing. This protects the internal semiconductor from moisture and contaminants, improving long-term stability and enabling operation in harsh environments.

Why is low Zener impedance important in voltage regulation?

Low Zener impedance, measured here at 7 ohms, reduces voltage fluctuations during current changes, leading to more accurate voltage regulation. This helps maintain a stable voltage output even when load conditions vary.

What temperature range can this diode safely operate within?

The device operates reliably between -65??C and +175??C, making it well-suited for industrial and outdoor applications where temperature extremes are common. This wide range ensures performance stability and reduces the risk of failure due to thermal stress.
