Frequently Asked Questions
Q: What package type are these Zener diodes, and are they suitable for surface-mount PCB assembly?
A: Yes — all 2500 diodes in this kit use the LL34 (SOD-80) surface-mount package, which is widely compatible with automated SMT assembly processes and hand-soldering for prototype PCBs. The compact footprint makes them ideal for space-constrained circuit board designs.
Q: How are the 2500 pieces distributed across the different voltage values?
A: The 2500 diodes are distributed across 13 voltage values (3.3V, 3.9V, 4.7V, 5.1V, 7.5V, 8.2V, 10V, 12V, 15V, 16V, 18V, 20V, and 24V). Each value is represented in the lot, giving you a balanced mixed assortment for a wide range of voltage regulation and clamping applications.
Q: What is the maximum power rating of these SMD Zener diodes?
A: Each diode in this kit is rated at 0.5W (1/2 Watt), making them well-suited for low-power voltage regulation and reference circuits in consumer electronics, hobby projects, and repair work operating below 50Vac or 75Vdc.
Q: Are these Zener diodes RoHS compliant or free from high-concern chemicals?
A: According to the product specifications, no high-concern chemicals (SVHC) are present in these components, which is consistent with RoHS-friendly manufacturing practices. Always verify compliance documentation with your supplier if required for industrial or commercial production.
