The 10 PCS Zener Diode 0.5W X55C DO35 Kit (X55C18V) is a compact set of fixed voltage Zener diodes designed for low power voltage regulation and reference tasks in electronics. Supplied in the standard DO35 axial package, these diodes are suitable for throughhole assembly, prototyping, and compact circuit designs. Key benefits Readytouse voltage options: includes a range of fixed Zener voltages (3V3, 5V1, 10V, 12V, 13V, 15V, 20V, 30V) to support common regulation and reference needs. Space saving and easy to install: DO35 axial package enables straightforward throughhole mounting on boards and in pointtopoint circuits. 0.5W power rating: suitable for lowcurrent regulation tasks and reference circuits in small projects. Versatile for quick design changes: a single kit provides multiple voltages for testing, tuning, and replacement without sourcing individual diodes. Brand and model consistency: aligned with the X55C18V designation, maintaining product line compatibility and availability for repairs or replacements. Key attributes Functionality: fixedvoltage Zener diodes for voltage regulation, reference generation, and clamping in lowpower circuits. Voltage range: multivoltage set including 3V3, 5V1, 10V, 12V, 13V, 15V, 20V, and 30V options (10 pieces in total). Power rating: 0.5W each. Package and form factor: DO35 axial lead Zener diodes suitable for throughhole mounting. Quantity: 10 pieces in the kit. Model: X55C18V, with the DO35 packaging and the specified voltage options. Applications and use cases Simple fixedvoltage regulation: provide stable reference voltages for microcontroller power supplies and sensor circuitry in lowcurrent designs. Reference voltage sources: serve as discrete voltage references in test rigs, performance benchmarking, and calibration setups. Input protection and voltage clamping: protect sensitive ICs and signal lines by clamping excessive voltages in hobbyist or prototype projects. How to use Identify the required fixed voltage for your circuit (for example, 5.1V or 12V). Insert the Zener diode in a suitable DO35 throughhole position as a shunt regulator or reference element according to the circuit design. Ensure the current is within the diode's operating range for your application to avoid exceeding the 0.5W rating. Notes Handle with standard ESD precautions and install on appropriate boards or prototyping tools. This kit provides a range of common Zener voltages in a single package to simplify stocking and prototyping workflows.
