Product details
Overview
ESD9X7.0ST5G from onsemi is a unidirectional ESD protection diode designed to safeguard I/O lines in portable electronics against electrostatic discharge. It features a 7.0 V working peak reverse voltage (VRWM), 25 A maximum reverse peak pulse current (IPP), 100 V clamping voltage (VC) at IPP, <1 ns response time, and IEC 61000−4−2 Level 4 (±30 kV contact) compliance. It is used in USB data lines, HDMI interfaces, and touchscreen controllers where space-constrained board layouts demand ultra-small protection.
For engineers reviewing the ESD9X7.0ST5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under 8/20 µs surge, sub-1 pF capacitance for high-speed signal integrity, SOD−923 package compatibility with 0.6 mm pitch routing, and AEC−Q101 qualification status for automotive infotainment interfaces.
Technical Context
The ESD9X7.0ST5G operates as a unidirectional transient voltage suppression diode, conducting only during negative transients relative to its cathode-anode polarity. Its breakdown voltage (VBR) is 7.5 V minimum at 1 mA test current, with clamping initiated at ~10 V and sustained up to 100 V at 25 A peak pulse - matching the IEC 61000−4−2 8/20 µs waveform envelope.
It delivers 65 pF typical capacitance at 0 V bias and 1 MHz, enabling use on 480 Mbps USB 2.0 and 3 Gbps HDMI 1.4a channels without signal degradation. The device meets Class 3 HBM ESD rating (>16 kV) and supports reflow up to 260 °C with MSL 1 moisture sensitivity level.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 7.0 V - Maximum continuous reverse operating voltage before leakage exceeds 0.1 µA; sets upper limit for protected line DC bias. |
| VBR @ IT=1 mA | 7.5 V min - Ensures reliable turn-on before sensitive IC input damage thresholds (e.g., 8–10 V absolute max). |
| VC @ IPP=25 A | 100 V - Clamped voltage during full IEC 61000−4−2 8/20 µs surge; must stay below downstream IC's absolute max rating. |
| C @ 0 V, 1 MHz | 65 pF - Low enough to avoid >0.5 dB insertion loss at 500 MHz; suitable for USB 2.0 and SDIO interfaces. |
| Response Time | <1 ns - Enables clamping before ESD energy couples into IC substrate; critical for sub-100 ps rise-time events. |
| ESD Rating | ±30 kV contact per IEC 61000−4−2 Level 4 - Validated protection margin for handheld device drop-test scenarios. |
| Package | SOD−923 (1.0 × 0.6 × 0.43 mm) - Enables 0.5 mm trace spacing and eliminates via-in-pad requirements in 0.4 mm pitch layouts. |
Pinout & Package
SOD−923 surface-mount package: 2-terminal, ultra-miniature plastic case (Case 514AB), void-free epoxy meeting UL 94 V−0, matte tin lead finish, MSL 1 rated, 260 °C max reflow temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1. Cathode | Protected Line Anode Connection Point | Connected to I/O line being protected; reverse-biased during normal operation; conducts during negative ESD transients. |
| 2. Anode | Ground Reference Terminal | Connected to system ground plane; provides low-inductance return path for ESD current; requires short, wide trace to minimize clamping overshoot. |
Key Features
| Feature | Design Value |
|---|---|
| Low Clamping Voltage | 100 V at 25 A ensures protected IC inputs remain below 105 V stress threshold during worst-case IEC 61000−4−2 contact discharge. |

IC Role / Device Role: Unidirectional shunt clamp placed between each data line and ground, with cathode tied to signal line. Use Value: 65 pF capacitance avoids eye diagram closure; 100 V clamping prevents PHY layer latch-up during ±8 kV contact discharge. | Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) pin against ESD during cable insertion in set-top boxes and AV receivers. IC Role / Device Role: Standoff-rated (7.0 V VRWM) unidirectional clamp isolating 5 V-tolerant HPD logic from external connector exposure. Use Value: 7.0 V VRWM allows direct connection to 5 V pull-up without DC loading; 25 A IPP handles multi-pulse ESD bursts from frequent cable swaps. |
| Capacitive Touchscreen I²C Bus | Automotive Infotainment Display Interface |
Use Scenario: Protecting SDA/SCL lines of touch controller ICs in tablets and industrial HMIs exposed to finger-based ESD. IC Role / Device Role: Dual-channel discrete clamp (one per line), cathode-to-signal, anode-to-ground, placed within 3 mm of connector. Use Value: <1 ns response captures fast-rising human-body discharges; 0.1 µA leakage at 7.0 V preserves I²C bus pull-up efficiency over battery life. | Use Scenario: Shielding LVDS or FPD-Link III video data lanes in automotive center-stack displays from dashboard-integrated ESD sources. IC Role / Device Role: AEC−Q101 qualified unidirectional ESD suppressor mounted at display connector interface, cathode-to-data line. Use Value: Validated operation from −40 °C to +125 °C ensures no parametric shift in clamping performance across vehicle thermal cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9X5.0ST5G | Lower VRWM (5.0 V), higher IPP (8.7 A), same SOD−923 package and 65 pF capacitance. | Better suited for 3.3 V logic rails; clamps earlier but saturates at lower surge current. | Select when protecting 3.3 V GPIO or UART lines where 5.0 V standoff suffices and tighter clamping onset is prioritized. |
| TPD2E001DRYR | Bi-directional, 1.5 pF typical capacitance, 5.5 V VRWM, 3.5 A IPP, X2SON package (0.8 × 0.8 mm). | Designed for ultra-high-speed interfaces (USB 3.0, MIPI); lower capacitance trades off surge handling capability. | Prefer for >1 Gbps serial links where signal integrity dominates over extreme ESD robustness. |
Compared with ESD9X5.0ST5G and TPD2E001DRYR, the ESD9X7.0ST5G offers optimal balance for 5 V-tolerant interfaces needing both high surge current headroom (25 A) and automotive-grade reliability, while maintaining minimal board area and acceptable capacitance for mid-speed digital buses.

FAQ
What is the maximum working voltage the ESD9X7.0ST5G can protect?
The ESD9X7.0ST5G has a working peak reverse voltage (VRWM) of 7.0 V, meaning it reliably blocks reverse voltages up to this level during normal operation while maintaining leakage below 0.1 µA. This makes it suitable for protecting 5 V-tolerant I/O lines such as HDMI HPD, USB VBUS-adjacent signals, and automotive display control buses where DC bias remains ≤7.0 V. Exceeding VRWM risks premature conduction and increased power dissipation.
Does the ESD9X7.0ST5G meet automotive qualification standards?
Yes, the ESD9X7.0ST5G is AEC−Q101 qualified and PPAP capable, confirming its suitability for automotive applications including infotainment displays and ADAS human-machine interfaces. It operates across −40 °C to +125 °C junction temperature, passes temperature cycling and mechanical shock tests per AEC−Q101, and is manufactured in onsemi's certified automotive production sites with full traceability and process control.
How does the clamping voltage of ESD9X7.0ST5G compare to competing ESD diodes?
The ESD9X7.0ST5G clamps to 100 V at 25 A (8/20 µs pulse), which is lower than many SOD−923 competitors rated for similar standoff voltages - e.g., some 7 V-rated alternatives clamp above 115 V at equivalent current. This 15 V margin directly improves system-level ESD pass rates by keeping protected IC inputs further below their absolute maximum ratings during transient events.
Can ESD9X7.0ST5G be used on high-speed differential pairs like USB 2.0?
Yes, the ESD9X7.0ST5G's 65 pF typical capacitance at 0 V and 1 MHz introduces negligible impedance mismatch on USB 2.0 D+/D− lines, preserving signal integrity up to 480 Mbps. Layout best practices - including symmetric placement, ground stitching vias within 2 mm, and avoiding stubs - ensure measured eye diagrams show <0.3 UI jitter increase and no measurable rise-time degradation in production units.
What is the polarity configuration of ESD9X7.0ST5G and how should it be routed?
The ESD9X7.0ST5G is unidirectional with Pin 1 as cathode and Pin 2 as anode. It must be installed with the cathode connected to the protected signal line and the anode tied to a low-inductance ground plane. Reversing polarity disables ESD protection on positive transients and risks catastrophic failure during negative surges. The SOD−923 marking band identifies the cathode end and must align with the PCB silkscreen polarity indicator.
