Product details
Overview
ESD5Z5.0T5G from onsemi is a unidirectional ESD protection diode in SOD-523 package, designed to clamp transient voltages up to 11.6 V at 5.0 A peak pulse current, with 5.0 V working peak reverse voltage, <1 ns response time, and IEC61000-4-2 Level 4 (±30 kV contact) compliance for protecting USB, HDMI, and audio interfaces in portable electronics.
For engineers reviewing the ESD5Z5.0T5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage at rated IPP, capacitance (80 pF), stand-off voltage margin, PCB space constraints (<1.20 mm × 0.80 mm footprint), and automotive-grade availability via SZ-prefix variants.
Technical Context
The ESD5Z5.0T5G operates as a unidirectional TVS diode, leveraging silicon avalanche breakdown to divert ESD transients away from sensitive ICs. Its 5.0 V VRWM ensures compatibility with 3.3 V and 5 V logic rails while maintaining sufficient margin above system operating voltage.
Clamping occurs within <1 ns of transient onset, limiting voltage stress to ≤11.6 V at 5 A (8/20 µs), and it sustains 174 W peak power per IEC61000-4-2. The device meets AEC-Q101 when ordered as SZESD5Z5.0T5G and supports reflow up to 260 °C with MSL 1 rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous reverse voltage before leakage exceeds 50 nA; sets safe operating margin for 3.3 V/5 V interfaces. |
| VC @ IPP = 5.0 A | 11.6 V - Clamped voltage during 8/20 µs surge; determines maximum stress on protected IC input pins. |
| IPP Max | 9.4 A - Peak pulse current capability per IEC61000-4-2; defines robustness against ±30 kV contact ESD events. |
| C @ 0 V, 1 MHz | 80 pF - Junction capacitance; impacts signal integrity in high-speed lines like USB 2.0 or HDMI DDC. |
| Response Time | <1 ns - Time to enter clamping conduction; ensures protection before transient propagates into IC core. |
| ESD Rating | Class 3 HBM (>16 kV) - Validated per JESD22-A114; qualifies for handheld and wearable end-equipment. |
| Package | SOD-523 - 1.20 mm × 0.80 mm × 0.60 mm footprint; enables placement adjacent to connectors with minimal board area. |
Pinout & Package
SOD-523 surface-mount package with cathode marked by polarity band; total body height 0.60 mm, void-free thermosetting epoxy meeting UL 94 V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded) | Cathode | Connected to protected line (e.g., USB D+); conducts during positive transients to ground. |
| 2 | Anode | Connected to system ground; completes low-impedance path for ESD current diversion. |
Key Features
| Feature | Design Value |
|---|---|
| Low clamping voltage | 11.6 V at 5 A enables protection of 3.3 V I/O without violating absolute maximum ratings of modern SoCs. |
| Ultra-small footprint | 1.20 mm × 0.80 mm SOD-523 allows placement directly at connector entry points, minimizing trace inductance. |
| IEC61000-4-2 Level 4 compliance | ±30 kV contact discharge support ensures pass/fail reliability in final system-level ESD testing. |
| Low leakage current | 50 nA max at 5.0 V VRWM prevents signal degradation or battery drain in always-on sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z5.0T1G | Same electrical specs and SOD-523 package; differs only in tape-and-reel quantity (3000 vs. 8000 units). | No functional difference; suitable for lower-volume prototyping or small-batch builds. | Select ESD5Z5.0T1G when smaller reel size aligns with assembly line feeder constraints or inventory turnover goals. |
| SZESD5Z5.0T5G | Identical clamping, capacitance, and footprint; certified to AEC-Q101 and PPAP capable. | Required for automotive infotainment, telematics, or ADAS subsystems where qualification documentation is mandatory. | Choose SZESD5Z5.0T5G for production programs needing automotive-grade traceability, change control, and failure analysis support. |
Compared with ESD5Z5.0T1G and SZESD5Z5.0T5G, the ESD5Z5.0T5G offers identical protection performance and packaging but targets high-volume industrial and consumer manufacturing with optimized reel size-making it ideal for automated SMT lines requiring extended run time between reel changes.

FAQ
What is the maximum clamping voltage of ESD5Z5.0T5G under IEC61000-4-2 surge conditions?
The ESD5Z5.0T5G clamps to a maximum of 11.6 V at 5.0 A peak pulse current (8/20 µs waveform), as specified in the onsemi datasheet. This value represents the upper limit of voltage seen by the protected circuit during a standardized ESD event, ensuring compatibility with 3.3 V and 5 V I/O structures. The actual clamping voltage may be lower depending on test setup parasitics and current magnitude.
Is ESD5Z5.0T5G suitable for bidirectional signal lines such as USB D+/D−?
No - ESD5Z5.0T5G is a unidirectional diode intended for single-ended lines referenced to ground (e.g., VBUS, MIC_BIAS, DDC_SCL). For bidirectional differential pairs like USB D+/D−, a bidirectional variant such as ESD7L5.0DT5G or dual-rail configuration is required. Using ESD5Z5.0T5G on bidirectional lines risks forward conduction during normal signal swings.
What is the junction capacitance of ESD5Z5.0T5G and how does it affect high-speed interfaces?
The ESD5Z5.0T5G exhibits 80 pF typical capacitance at 0 V and 1 MHz, measured across its terminals. In USB 2.0 applications, this adds measurable loading to data lines and may degrade signal rise/fall times or eye opening if placed directly in series with D+/D−. It is best applied on auxiliary lines (VBUS, ID, or DDC) rather than primary high-speed differential paths.
Does ESD5Z5.0T5G meet automotive qualification standards?
Standard ESD5Z5.0T5G is not AEC-Q101 qualified; however, the SZESD5Z5.0T5G variant - identical in all electrical and mechanical specifications - is fully AEC-Q101 qualified and PPAP capable. Engineers designing for automotive infotainment or body control modules must specify the SZ-prefix part to satisfy OEM qualification requirements.
What is the thermal resistance and power derating behavior of ESD5Z5.0T5G?
ESD5Z5.0T5G has no published RθJA value due to its transient-only duty cycle; its 500 mW steady-state dissipation rating applies only to DC or low-duty-cycle conditions. During ESD events, energy is absorbed in <100 ns, so thermal mass dominates over convection. Derating is unnecessary for compliant IEC61000-4-2 pulses, but repeated surges require PCB copper area ≥1 cm² per the datasheet's FR-4 test condition.
