Frequently Asked Questions

Q: What is the difference between a TVS diode and an ESD protection diode?

A: A TVS (Transient Voltage Suppressor) diode is designed to absorb high-energy transient voltage spikes, such as those caused by lightning or inductive load switching, and can handle relatively higher surge currents. An ESD (Electrostatic Discharge) protection diode is optimized for very fast, low-energy transients generated by static electricity — common when handling PCBs or connecting cables. Many of the components in this pack, such as the PESD-series parts, are specifically engineered for ESD protection on data lines and interface circuits.

Q: How many pieces of each model number are included?

A: The pack contains a total of 20 pieces distributed across the listed model numbers (PESD3V3L1BA, PESD3V3S2UT, PESD3V3L5UY, PESD1IVN27-AX, PESD5V0U1UA, PESD1LIN, PESD5V0L2BTN, PESD15VL2BT-N). If you need a specific quantity split or a larger custom order, please reach out via our store contact form.

Q: Are these surface-mount (SMD) components?

A: Yes. All components in this TVS/ESD protection diode assortment are surface-mount devices (SMD), making them compatible with modern PCB designs and reflow soldering processes. Refer to the individual datasheet for each part number for exact package dimensions and soldering specifications.
