Product details
Overview
ESD9D5.0ST5G from onsemi is a bidirectional ultra-low-capacitance ESD protection diode in SOD-923 package, featuring 0.6 pF capacitance, 5.0 V stand-off voltage, 13.5 V clamping voltage at 1 A, <1.0 ns response time, and IEC 61000-4-2 Level 4 (±8 kV contact) compliance - deployed for high-speed USB 2.0 data line and antenna port protection.
For engineers reviewing the ESD9D5.0ST5G datasheet, pinout, applications, or equivalent options, key selection criteria include sub-1 pF capacitance, bidirectional clamping behavior, SOD-923 footprint constraints, and verified ±8 kV IEC ESD robustness in real-world signal integrity-critical interfaces.
Technical Context
This device implements a silicon avalanche diode structure optimized for fast transient suppression without parasitic degradation of high-frequency signal paths. Its bidirectional configuration enables symmetric clamping on both polarities of differential or single-ended lines, with breakdown voltage specified at 5.4 V minimum and clamping voltage tightly controlled at 13.5 V max under 1 A 8/20 µs surge.
The SOD-923 package supports automated placement in space-constrained layouts, and its 1.0 mm × 0.6 mm body with 0.37 mm height meets MSL 1 reflow requirements up to 260 °C. Leakage current remains ≤1.0 µA at 5.0 V reverse bias, preserving signal integrity in low-power RF and USB receivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance | 0.6 pF at 0 V, 1 MHz - preserves signal integrity in USB 2.0 (480 Mbps) and cellular antenna paths |
| Stand-off Voltage | 5.0 V - blocks normal operating voltage while enabling conduction above ESD threshold |
| Clamping Voltage | 13.5 V max at 1 A IPP - limits transient overvoltage to safe levels for downstream 3.3 V or 5 V ICs |
| ESD Rating | IEC 61000-4-2 Level 4: ±8 kV contact - validated protection for handheld and portable end equipment |
| Response Time | <1.0 ns - activates before sensitive circuitry sustains damage during nanosecond-scale ESD events |
| Leakage Current | ≤1.0 µA at 5.0 V - avoids DC loading on high-impedance RF front-end or sensor inputs |
| Package | SOD-923 (1.00 mm × 0.60 mm × 0.37 mm) - enables placement adjacent to connectors without trace stubs |
Pinout & Package
SOD-923 surface-mount package: 2-terminal, ultra-compact plastic case (Case 514AB), void-free epoxy meeting UL 94 V-0, matte tin lead finish, MSL 1 rated, 0.4 mm max body height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Protected Line Terminal (Anode-side connection in bidirectional operation) | Connected to I/O line; forms one side of symmetrical clamping path to ground or rail |
| 2 (Anode) | Protected Line Terminal (Cathode-side connection in bidirectional operation) | Connected to same I/O line; completes bidirectional ESD current path with Pin 1 |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 0.8 pF capacitance, 5.5 V stand-off, unidirectional configuration | Requires separate anode/cathode routing; less suitable for AC-coupled or differential lines | Prefer ESD9D5.0ST5G when bidirectionality and lowest possible capacitance are mandatory |
| UMK105CG600JV-F | Ceramic multilayer capacitor (MLCC) with no clamping function; used only as filter, not ESD suppressor | Provides filtering but zero ESD protection; must be paired with dedicated TVS | ESD9D5.0ST5G delivers integrated clamping + filtering in one device; MLCC-only solution increases BOM count and layout complexity |
Compared with TPD2E001DRYR and UMK105CG600JV-F, the ESD9D5.0ST5G uniquely combines bidirectional operation, 0.6 pF capacitance, and ±8 kV ESD rating in a single 1.0 mm × 0.6 mm device - making it optimal for space-limited, high-frequency I/O protection where discrete TVS diodes or passive filters alone cannot meet both signal integrity and robustness requirements.

FAQ
What is the clamping voltage specification for ESD9D5.0ST5G under IEC 61000-4-2 testing?
The ESD9D5.0ST5G has a maximum clamping voltage of 13.5 V at 1 A peak pulse current (IPP), measured per the IEC 61000-4-2 waveform. This value is confirmed in the Electrical Characteristics table of the official onsemi datasheet (Rev. 3, October 2024) and reflects the voltage seen across the device during an 8 kV contact ESD event. The ESD9D5.0ST5G maintains this clamping performance bidirectionally, protecting both positive and negative transients.
Is ESD9D5.0ST5G suitable for USB 2.0 high-speed (480 Mbps) data lines?
Yes, the ESD9D5.0ST5G is explicitly qualified for USB 2.0 high-speed applications due to its 0.6 pF typical capacitance at 0 V and 1 MHz - low enough to avoid measurable signal integrity degradation at 480 Mbps. Its bidirectional architecture allows placement on D+ and D− lines without polarity concerns, and its 13.5 V clamping ensures downstream 3.3 V transceivers remain within safe operating limits during ESD events. The datasheet cites USB 2.0 as a primary target application.
What is the package type and dimensions of ESD9D5.0ST5G?
The ESD9D5.0ST5G uses the SOD-923 package (Case 514AB), measuring 1.00 mm × 0.60 mm × 0.37 mm. It features a 2-terminal configuration with cathode marked by a polarity band on Pin 1. The package is Pb-free, RoHS-compliant, UL 94 V-0 rated, and qualified for MSL 1 handling with peak reflow temperature up to 260 °C. This compact outline enables placement directly at high-speed connectors with minimal trace length.
Does ESD9D5.0ST5G support bidirectional or unidirectional ESD protection?
The ESD9D5.0ST5G is a bidirectional ESD protection diode, meaning it provides symmetrical clamping for both positive and negative transients on the same I/O line. This is confirmed by its electrical schematic symbol (two opposing diodes), IEC 61000-4-2 test results showing identical ±8 kV performance, and the "Bi-Directional" label in the datasheet's Electrical Characteristics section. Its dual-terminal SOD-923 configuration does not distinguish anode/cathode for functional operation - both pins serve as protected line terminals.
What is the maximum leakage current of ESD9D5.0ST5G at its rated stand-off voltage?
The maximum reverse leakage current (IR) for ESD9D5.0ST5G is 1.0 µA at VRWM = 5.0 V and TA = 25 °C, as specified in the Electrical Characteristics table. This low leakage ensures minimal DC loading on high-impedance nodes such as RF antenna feeds or sensor interfaces, preserving accuracy and power efficiency. The value is measured under steady-state DC conditions and remains stable across the full operating temperature range (−55 °C to +125 °C).
