Product details
Overview
ESD9C5.0ST5G from onsemi is a unidirectional ESD protection diode in SOD-923 package, featuring 5.0 V working peak reverse voltage (VRWM), 6.0 V max clamping voltage (VC) at 1 A IPP, 6.2 pF typical capacitance at 1 MHz, <1 ns response time, and IEC 61000-4-2 Level 4 (±8 kV contact) compliance - deployed on high-speed data lines in smartphones and USB interfaces.
For engineers reviewing the ESD9C5.0ST5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under 8 kV IEC discharge, sub-7 pF capacitance for signal integrity preservation, SOD-923 footprint compatibility, and unidirectional polarity for rail-to-rail protection of 5 V logic interfaces.
Technical Context
This device implements a single-channel unidirectional TVS structure optimized for board-level ESD suppression on I/O lines. It operates with a 5.0 V standoff voltage and clamps transients to ≤6.0 V at 1 A peak pulse current, enabling protection of 5 V CMOS inputs without forward conduction during normal operation.
The SOD-923 package supports high-density routing with 1.0 mm × 0.60 mm body and 0.37 mm max height. Its low 6.2 pF capacitance minimizes signal distortion on USB 2.0, HDMI, and MIPI D-PHY interfaces while maintaining Class 3 HBM (>16 kV) and IEC61000-4-2 Level 4 (±8 kV contact) ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous reverse voltage before leakage exceeds 0.5 μA; sets operating margin for 5 V supply rails. |
| VC @ IPP = 1 A | 6.0 V max - Clamped voltage during 8 kV IEC contact discharge; ensures downstream ICs see <6.0 V stress. |
| C @ 1 MHz, 0 V | 6.2 pF typ - Low enough to avoid signal attenuation on 480 Mbps USB 2.0 differential pairs. |
| Response Time | <1 ns - Fast enough to suppress ESD events before internal IC protection triggers. |
| IEC61000-4-2 | ±8 kV contact, ±15 kV air - Meets Level 4 immunity standard for handheld consumer electronics. |
| HBM ESD Rating | >16 kV - Complies with Class 3 human-body model for robust handling in manufacturing. |
| Package | SOD-923 - 1.0 mm × 0.60 mm × 0.37 mm footprint; compatible with 0201 reflow profiles and automated placement. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9B5.0ST5G | Bidirectional configuration; same VRWM (5.0 V), higher VC (7.5 V max), identical SOD-923 package. | Required where both positive and negative transients occur on same line (e.g., audio jack, antenna feed). | Select ESD9B5.0ST5G only when bidirectional clamping is mandatory; ESD9C5.0ST5G offers lower VC for unidirectional 5 V rail protection. |
| TPD2E001DRYR | Two-channel array in X2SON-4; 5.5 V VRWM, 10 pF typical C, ±12 kV IEC contact rating. | Used when protecting multiple lines (e.g., USB D+/D− simultaneously) with shared ground reference. | Choose TPD2E001DRYR for dual-line integration; ESD9C5.0ST5G provides superior 6.2 pF/6.0 V performance for single-line optimization. |
Compared with ESD9B5.0ST5G and TPD2E001DRYR, the ESD9C5.0ST5G delivers the lowest clamping voltage (6.0 V) and lowest capacitance (6.2 pF) in a single-line SOD-923 package - making it optimal for high-speed 5 V interfaces where signal integrity and transient suppression headroom are both critical.

FAQ
What is the clamping voltage of ESD9C5.0ST5G under IEC61000-4-2 8 kV contact discharge?
The ESD9C5.0ST5G exhibits a maximum clamping voltage of 6.0 V at 1 A peak pulse current, measured per IEC61000-4-2 waveform conditions. This value is validated in the official onsemi datasheet and ensures protected 5 V logic circuits remain below their absolute maximum voltage ratings during standardized ESD events. The ESD9C5.0ST5G achieves this performance using a low-impedance silicon avalanche structure optimized for rapid turn-on.
Is ESD9C5.0ST5G unidirectional or bidirectional?
ESD9C5.0ST5G is a unidirectional ESD protection diode, configured with cathode (Pin 1) connected to the protected line and anode (Pin 2) tied to ground. It conducts only during positive transients on the line, making it ideal for rail-to-rail protection of 5 V supply-referenced signals. The ESD9C5.0ST5G does not provide symmetric clamping for negative excursions - use ESD9B5.0ST5G for bidirectional capability.
What package type does ESD9C5.0ST5G use, and what are its dimensions?
ESD9C5.0ST5G uses the SOD-923 package (Case 514AB), measuring 1.0 mm × 0.60 mm × 0.37 mm maximum height. Its ultra-small outline supports high-density PCB layouts near connectors and high-speed interfaces. The ESD9C5.0ST5G is supplied in tape-and-reel format (8,000 units per reel) and features Pb-free construction compliant with RoHS directives.
Can ESD9C5.0ST5G be used on USB 2.0 data lines?
Yes, ESD9C5.0ST5G is specifically suited for USB 2.0 D+ and D− line protection due to its 6.2 pF typical capacitance - low enough to maintain signal integrity at 480 Mbps without measurable eye closure. Its 6.0 V clamping voltage protects USB transceivers rated for 5.5 V absolute maximum, and its SOD-923 footprint allows placement directly at the connector. The ESD9C5.0ST5G meets IEC61000-4-2 Level 4, satisfying end-product USB compliance requirements.
What is the working peak reverse voltage (VRWM) rating for ESD9C5.0ST5G?
The ESD9C5.0ST5G has a working peak reverse voltage (VRWM) of 5.0 V, meaning it blocks up to 5.0 V in normal operation with leakage current limited to 0.5 μA. This rating aligns precisely with standard 5 V logic supply domains and ensures no forward conduction during steady-state operation. The ESD9C5.0ST5G maintains this specification across −55 °C to +150 °C junction temperature range.
