What are the key features of SP3021-01ETG?
- Low-capacitance silicon TVS diode with 7 V breakdown voltage and 14.7 V maximum clamping voltage for effective transient suppression
- Single bidirectional channel in MO-236 (SOT-523) package enabling space-efficient ESD protection on high-speed data lines
- Silicon construction with JEDEC MO-236 footprint for straightforward PCB integration in compact consumer and industrial designs
What is SP3021-01ETG used for?
The SP3021-01ETG provides ESD and transient overvoltage protection for high-speed serial data lines including USB, HDMI, and MIPI interfaces where low capacitance is critical to preserving signal integrity. Its 7 V breakdown and 14.7 V clamping voltage protect downstream ICs from electrostatic discharge events on I/O pins in consumer electronics, smartphones, and portable devices. The compact SOT-523 (MO-236) package supports dense PCB layouts where multiple protection diodes must be placed close to connectors.

Frequently Asked Questions
What are the breakdown and clamping voltage ratings of the SP3021-01ETG, and how do they protect downstream circuitry?
The SP3021-01ETG has a 7 V minimum breakdown voltage and clamps transient events to a maximum of 14.7 V. This means any ESD spike or surge on the protected line is limited to 14.7 V before reaching downstream ICs, preventing gate oxide breakdown in logic circuits typically rated for 3.3 V or 5 V operation.
Why is the low-capacitance design of the SP3021-01ETG important for high-speed data interface protection?
At high data rates such as USB 3.0 (5 Gbps) or HDMI 2.0 (up to 18 Gbps), even a few picofarads of shunt capacitance from a protection device degrades eye diagram quality and increases bit error rate. The SP3021-01ETG's low-capacitance silicon construction minimizes signal loading while still providing ESD clamping to 14.7 V, preserving signal integrity across high-frequency data lines.
In which PCB form factors and applications is the SP3021-01ETG most commonly deployed?
The SP3021-01ETG is packaged in a SOT-523 (MO-236, PBCC-N2) surface-mount footprint measuring approximately 1.6 × 0.8 mm, making it a popular choice for protecting I/O pins on smartphones, tablets, and notebook computers. It is also used near connector-side ESD protection in USB hubs, HDMI switches, and portable industrial data acquisition devices where board space is under 2 mm per protection node.
