Product details
Overview
ESD9M5.0ST5G from onsemi is a unidirectional ESD protection diode designed for high-speed data lines such as USB 2.0, with 2.5 pF capacitance, 5.0 V working peak reverse voltage, 9.8 V clamping voltage at 1 A pulse, IEC61000-4-2 Level 4 (±15 kV air/±10 kV contact) compliance, and SOD-923 package.
For engineers reviewing the ESD9M5.0ST5G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance for signal integrity, sub-1 ns response time, AEC-Q101 qualification status, and compatibility with automated SMT assembly in space-constrained portable electronics.
Technical Context
This device operates as a transient voltage suppression (TVS) diode in unidirectional configuration, leveraging silicon avalanche breakdown to clamp ESD transients before they reach downstream ICs. Its low 2.5 pF junction capacitance minimizes signal distortion on 480 Mbps USB 2.0 differential pairs.
The ESD9M5.0ST5G delivers 9.8 V clamping at 1 A IPP per IEC61000-4-2 waveform, with <1.0 ns response time and 5.0 V stand-off voltage - enabling robust protection without interfering with normal 5 V logic or USB VBUS signaling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance | 2.5 pF @ 0 V, 1 MHz - preserves signal integrity on USB 2.0, HDMI, and other high-speed interfaces |
| Clamping Voltage | 9.8 V @ 1 A IPP - limits transient overvoltage to safe levels for 3.3 V/5 V interface ICs |
| Stand-off Voltage | 5.0 V - matches standard USB VBUS and 5 V logic rails without leakage or false triggering |
| ESD Rating | IEC61000-4-2 Level 4: ±15 kV air / ±10 kV contact - meets industrial and consumer end-equipment immunity requirements |
| Response Time | <1.0 ns - activates faster than most interface ICs can be damaged by ESD stress |
| Package | SOD-923 (1.00 mm × 0.60 mm × 0.37 mm) - enables placement adjacent to connectors in ultra-thin mobile PCBs |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 2-channel bidirectional array; 1.2 pF per line; 5.5 V stand-off; no AEC-Q101 qualification | Better suited for dual-line protection (e.g., USB D+/D− together); lacks automotive qualification | Select when dual-line layout efficiency outweighs automotive compliance needs |
| SMF5.0AT1G | Higher capacitance (35 pF); higher clamping (14.5 V); DO-214AC package (4.5 mm × 2.7 mm) | Targeted at lower-speed power/signal lines where board space and speed are less constrained | Choose only for non-high-speed applications where 2.5 pF is not required |
Compared with TPD2E001DRYR and SMF5.0AT1G, the ESD9M5.0ST5G uniquely balances ultra-low capacitance, automotive qualification, and miniature SOD-923 packaging - making it optimal for space-limited, high-speed, and automotive-grade USB/HDMI protection where signal fidelity and reliability are co-prioritized.

FAQ
What is the maximum clamping voltage of the ESD9M5.0ST5G during an ESD event?
The ESD9M5.0ST5G exhibits a maximum clamping voltage of 9.8 V at 1 A peak pulse current (IPP) per the IEC61000-4-2 waveform. This value is measured across the device terminals during standardized 8 kV contact discharge testing and ensures downstream 3.3 V or 5 V ICs remain within safe operating voltage margins. The ESD9M5.0ST5G achieves this while maintaining ultra-low 2.5 pF capacitance - critical for preserving signal integrity on high-speed lines.
Is the ESD9M5.0ST5G suitable for automotive applications?
Yes, the ESD9M5.0ST5G is AEC-Q101 qualified and PPAP capable when ordered with the SZ prefix (e.g., SZESD9M5.0ST5G). It undergoes rigorous stress testing including temperature cycling, mechanical shock, and ESD survivability per automotive standards. Its SOD-923 package, 100% matte tin finish, and operation across −55 °C to +150 °C junction temperature make it appropriate for infotainment, ADAS camera links, and telematics interfaces where space and reliability are critical.
What is the package type and dimensions of the ESD9M5.0ST5G?
The ESD9M5.0ST5G uses the SOD-923 package (case 514AB), measuring 1.00 mm × 0.60 mm × 0.37 mm with a 0.3 mm pitch. It features a cathode polarity band marking, 100% matte tin leads, and complies with MSL 1 moisture sensitivity level. This ultra-small outline allows placement directly at USB or HDMI connectors on dense PCBs - a key advantage over larger packages like SOD-323 or DO-214AC for high-speed routing.
Does the ESD9M5.0ST5G support bidirectional ESD protection?
No, the ESD9M5.0ST5G is a unidirectional ESD protection diode, configured to protect circuits referenced to ground with a defined polarity - specifically, it clamps positive transients on the cathode side and conducts negative transients through its internal structure to ground. For true bidirectional protection (e.g., differential lines like USB D+/D− requiring symmetric clamping), a dedicated bidirectional array such as TPD2E001DRYR would be required instead of the ESD9M5.0ST5G.
What is the leakage current specification for the ESD9M5.0ST5G at its working voltage?
The ESD9M5.0ST5G specifies a maximum reverse leakage current (IR) of 1.0 µA at its working peak reverse voltage of 5.0 V and ambient temperature of 25 °C. This low leakage ensures minimal impact on bias networks and signal integrity in high-impedance interfaces such as touch-sense inputs or precision analog front-ends - a key differentiator versus higher-leakage TVS devices that may introduce offset or drift in sensitive circuits.
