FAQ

What is the nominal Zener voltage of this diode, and why is it important?

The nominal Zener voltage is 33 volts, which is critical because it determines the voltage at which the diode breaks down and maintains a constant voltage. This property is essential for voltage regulation and reference applications to ensure circuit stability.

What power dissipation can the device handle, and how does this impact application design?

The diode can safely dissipate up to 5 watts, allowing it to operate in higher power conditions without damage. This high power rating enables its use in circuits with substantial current loads, reducing the risk of thermal failure in demanding environments.

What is the significance of the Zener impedance in this component?

Zener impedance indicates the diode??s resistance to changes in current at the breakdown voltage. A low Zener impedance, like 30 ohms, means the voltage remains stable even when the current varies, improving overall circuit reliability and performance.

How does the operating temperature range affect its suitability for industrial use?

The wide temperature range from -65 ??C to +200 ??C ensures the diode can function reliably in harsh industrial and automotive environments where temperature extremes are common. This makes it suitable for applications requiring long-term stability under fluctuating thermal conditions.

What package type is used, and why is this relevant for engineers?

The diode uses a DO-41 package, a standard through-hole form factor that facilitates easy mounting and replacement in printed circuit boards. This packaging choice ensures compatibility with existing manufacturing processes and supports robust mechanical and thermal handling.
