Zener Diode Kit — 30 Voltages, 300 Pieces, 0.5W DO-35 Product overview This kit contains 30 distinct Zener diode voltages spanning 2.0 V to 39 V in standard DO-35 (0.5 W) packages, with a total of 300 pieces. Each diode is clearly labeled for fast identification, making selection and sorting quick during prototyping, testing, and repair. Key benefits — why you need this kit Broad voltage coverage in one kit saves time: access common regulation and reference values from 2.0 V to 39 V without ordering individual parts. Ready-to-use inventory reduces stockouts and reorder cycles for common Zener values. Compact DO-35 package fits through-hole PCBs, breadboards, and fixtures for easy prototyping and assembly. Clear labeling and consistent, repeatable performance speed up testing, debugging, and experimentation. 0.5 W power rating is suitable for low- to moderate-power regulation, reference, and clamping tasks without excessive heat in small-signal applications. How this kit solves problems Eliminates guesswork selecting Zener voltages during design and bench testing by providing a wide range of standard values in one set. Minimizes downtime and procurement complexity by consolidating common parts into a single kit. Simplifies inventory and component management with a labeled, organized set ready for immediate use. Key attributes Voltage range: 2.0 V to 39 V (30 distinct values) Package: DO-35 through-hole Power rating: 0.5 W Quantity: 300 pieces total Identification: Each diode clearly labeled for fast selection Typical applications Regulate a microcontroller or peripheral supply from a bench supply or battery for quick prototype power rails. Provide a stable voltage reference in test rigs, sensor interfaces, or comparator circuits. Protect sensitive inputs and small-signal circuits by clamping transient or over-voltage events, including LED driver and signal-conditioning applications. What you get A compact, labeled set of 30 standard Zener voltages in DO-35 packages (0.5 W), totaling 300 pieces — convenient for prototyping, test benches, repairs, and small production runs.
