Product details
Overview
SZESD5Z6.0T1G from onsemi is a unidirectional ESD protection diode in SOD-523 package, featuring 6.0 V working peak reverse voltage (VRWM), 12.4 V clamping voltage at 5 A (VC), 70 pF capacitance at 0 V, <1 ns response time, and IEC 61000-4-2 Level 4 (±30 kV contact) compliance - deployed for high-speed data line protection in USB 2.0, HDMI, and audio interfaces.
For engineers reviewing the SZESD5Z6.0T1G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping performance under 8/20 µs surge, low capacitance for signal integrity, automotive-grade AEC-Q101 qualification, and SOD-523 footprint compatibility with space-constrained portable designs.
Technical Context
The SZESD5Z6.0T1G operates as a unidirectional transient voltage suppression diode, leveraging silicon avalanche breakdown to clamp ESD transients before they reach downstream ICs. Its design targets low-capacitance, high-speed signal lines where parasitic loading must be minimized without sacrificing robustness.
It delivers 12.4 V clamping at 5 A per IEC 61000-4-2 waveform, supports ±30 kV contact ESD immunity, and maintains only 0.01 µA max reverse leakage at VRWM - enabling reliable protection of 3.3 V and 5 V logic interfaces while preserving signal fidelity in high-frequency applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 6.0 V - Maximum continuous reverse operating voltage; ensures no conduction during normal 5 V rail operation. |
| VC @ IPP = 5 A | 12.4 V - Clamping voltage limits downstream IC stress during 8/20 µs surges; stays below typical 13.2 V absolute maximum for 5 V logic. |
| C @ 0 V, 1 MHz | 70 pF - Low capacitance minimizes signal distortion on USB 2.0 (480 Mbps) and audio paths; avoids timing skew or attenuation. |
| Response Time | <1 ns - Fast turn-on prevents transient energy from propagating past the diode into protected circuitry. |
| ESD Rating (HBM) | >16 kV - Meets Class 3 HBM requirement; protects against common handling-induced discharges in assembly and field use. |
| IEC 61000-4-2 | Level 4 (±30 kV contact) - Certified for direct ESD strikes on exposed ports in consumer and automotive infotainment systems. |
| AEC-Q101 Qualified | Yes - Validated for automotive temperature range (−55 °C to +150 °C) and reliability requirements; suitable for ADAS camera links and telematics modules. |
Pinout & Package
SZESD5Z6.0T1G is housed in an ultra-compact SOD-523 (Case 502) package measuring 1.20 mm × 0.80 mm × 0.60 mm, with gull-wing leads, matte tin finish, and MSL 1 reflow rating (260 °C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Protected Line Anode Connection | Connected to I/O line (e.g., USB D+); conducts during positive transients to shunt current to ground. |
| 2 (Anode) | Ground Reference Terminal | Connected to system ground plane; provides low-inductance return path essential for effective ESD clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Low Capacitance (70 pF) | Preserves signal rise/fall times on 480 Mbps USB 2.0 differential pairs without measurable jitter or eye closure. |
| Clamping Voltage (12.4 V @ 5 A) | Keeps transient voltage below 13.2 V - within safe margin of 5 V logic ICs' absolute maximum ratings. |
| AEC-Q101 Qualification | Validated for automotive under-hood and cabin environments, including thermal cycling and humidity exposure tests. |
| SOD-523 Footprint | Enables placement directly at connector entry points on dense PCBs - critical for minimizing trace inductance in ESD protection layout. |
| ±30 kV IEC 61000-4-2 | Guarantees pass/fail compliance on final product level ESD testing without requiring additional board-level shielding. |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z6.0T1G | Non-automotive grade; same electrical specs but not AEC-Q101 qualified; marking "ZF" instead of "ZG". | Intended for consumer electronics only; not validated for automotive temperature cycling or long-term reliability under vibration. | Select when cost sensitivity outweighs automotive qualification requirements and full lifecycle traceability is not mandated. |
| TPD2E001DRYR | 2-channel bidirectional array; 10 pF typical capacitance; 12 V clamping at 1 A; no AEC-Q101 certification. | Optimized for dual-line protection (e.g., USB D+/D−) in single device; lower capacitance but reduced surge handling (1 A vs. 5 A). | Prefer for ultra-high-speed interfaces where <15 pF is mandatory, accepting lower peak pulse current capability and non-automotive status. |
Compared with ESD5Z6.0T1G and TPD2E001DRYR, SZESD5Z6.0T1G uniquely combines automotive qualification, 5 A surge robustness, and 70 pF capacitance - making it optimal for safety-critical, high-reliability ESD protection in automotive camera and infotainment systems where both ruggedness and signal fidelity are required.

FAQ
What is the clamping voltage of SZESD5Z6.0T1G at 5 A peak pulse current?
The SZESD5Z6.0T1G exhibits a maximum clamping voltage (VC) of 12.4 V at 5 A peak pulse current per the 8/20 µs waveform defined in IEC 61000-4-2. This value is measured under standardized test conditions and ensures that downstream 5 V logic ICs remain within their absolute maximum voltage ratings during ESD events. The SZESD5Z6.0T1G datasheet confirms this parameter on page 3 in the Electrical Characteristics table.
Is SZESD5Z6.0T1G qualified for automotive applications?
Yes, SZESD5Z6.0T1G is AEC-Q101 qualified and PPAP capable, with validation across the full automotive temperature range (−55 °C to +150 °C). The "SZ" prefix explicitly denotes automotive and other applications requiring unique site and control change requirements. This makes SZESD5Z6.0T1G suitable for use in ADAS camera modules, infotainment systems, and telematics units where reliability under harsh environmental conditions is mandatory.
What package type does SZESD5Z6.0T1G use, and what are its dimensions?
SZESD5Z6.0T1G uses the SOD-523 package (Case 502, Style 1), with body dimensions of 1.20 mm × 0.80 mm × 0.60 mm. It features a cathode band on Pin 1 and anode on Pin 2, matte tin lead finish, and complies with MSL 1 moisture sensitivity level. The compact size enables placement directly at I/O connectors to minimize protection loop inductance - a critical factor for effective ESD suppression.
How does the capacitance of SZESD5Z6.0T1G affect high-speed signal integrity?
SZESD5Z6.0T1G has a maximum capacitance of 70 pF at 0 V and 1 MHz, which is optimized for USB 2.0 (480 Mbps) and audio interfaces where excessive loading causes signal degradation. At this level, the device introduces negligible rise-time delay or eye-diagram closure on differential pairs. For higher-speed interfaces like USB 3.0 or HDMI 2.0, lower-capacitance alternatives would be required - but SZESD5Z6.0T1G strikes a balance between ESD robustness and signal fidelity for mid-speed applications.
What is the difference between SZESD5Z6.0T1G and ESD5Z6.0T1G?
The primary distinction is qualification and marking: SZESD5Z6.0T1G carries the "SZ" prefix indicating AEC-Q101 qualification, automotive process controls, and PPAP capability, with device marking "ZG"; ESD5Z6.0T1G is the commercial-grade version (marking "ZF") without automotive validation. Both share identical electrical specifications (VRWM = 6.0 V, VC = 12.4 V, C = 70 pF), but only SZESD5Z6.0T1G is approved for automotive production programs requiring full traceability and extended reliability testing.
