Function and benefits - This Zener diode provides voltage regulation and circuit protection in DC systems. In reverse bias with a series resistor, it clamps the voltage to its Zener level, helping to stabilize rails and shield sensitive components. Package and mounting - Through Hole axial device with DO-41 encapsulation. Designed for reliable board mounting and straightforward soldering on both prototype and production PCBs. Power and performance - Power rating: 1W. Suitable for low to moderate current regulation tasks; derate for temperature to maintain reliability. Compatibility and use - Works in standard Zener regulator configurations, voltage references, and input protection circuits. Compatible with common supply rails and general purpose electronics, with resistor sizing to set current. Size and form - Through-hole axial package (DO-41) with standard leads, making it easy to integrate into through-hole designs and breadboarding. Performance notes - Operate within the 1W dissipation limit and consider temperature effects. Tolerances and exact Zener voltage depend on manufacturing and operating conditions. Use scenarios - Use case 1: Create a simple voltage reference for a microcontroller powered from a DC rail, using a resistor to set current through the Zener. - Use case 2: Protect a sensitive input line by clamping excessive voltages to a safe level. - Use case 3: Provide a basic reference in a small sensor conditioning circuit for stable signal processing.
