Frequently Asked Questions
Q: What are PESD and BZA ESD protection diodes used for?
A: PESD (Polymer ESD) and BZA series diodes are surface-mount transient voltage suppressor components designed to protect electronic circuits from electrostatic discharge (ESD) and voltage transients. They are commonly used on USB ports, data lines, HDMI interfaces, and microcontroller I/O pins to prevent damage from static electricity or sudden voltage spikes.
Q: Are these diodes compatible with standard PCB footprints?
A: Yes. The diodes in this assortment use common surface-mount footprints (including SOD-323, SOT-23, and SOT-363), which are widely supported in standard PCB design software such as KiCad, Eagle, and Altium. Always verify the specific part number datasheet for exact dimensions before soldering.
Q: How many pieces of each part number are included?
A: The pack contains 20 pieces total spread across the listed part numbers. The exact quantity per part number may vary within the assortment. This kit is ideal for stocking your component drawer with a range of ESD protection options.
Q: Where are these diodes made?
A: These ESD protection diodes are made in Mainland China.
