Product details
Overview
ESD5Z7.0T5G from onsemi is a unidirectional ESD protection diode in SOD-523 package, featuring 7.0 V working peak reverse voltage (VRWM), 13.5 V clamping voltage at 5 A (VC), 22.7 A maximum peak pulse current (IPP), and 65 pF capacitance - designed for high-density I/O line protection in portable electronics.
For engineers reviewing the ESD5Z7.0T5G datasheet, pinout, applications, or equivalent options, key selection criteria include IEC 61000-4-2 Level 4 compliance (±30 kV contact), <1 ns response time, low leakage (<10 nA @ 7.0 V), and compact 1.20 mm × 0.80 mm footprint with MSL 1 reflow capability.
Technical Context
The ESD5Z7.0T5G operates as a unidirectional transient voltage suppression diode, leveraging silicon avalanche clamping to divert ESD energy away from sensitive IC inputs. Its 7.0 V VRWM ensures compatibility with 5 V and 3.3 V logic interfaces while maintaining margin above signal swing.
It meets IEC 61000-4-2 Level 4 (±30 kV contact/air) and IEC 61000-4-4 Level 4 (40 A EFT), with clamping performance validated using the 8/20 µs pulse waveform per Figure 5. Junction temperature range spans −55 °C to +150 °C, supporting automotive and industrial ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 7.0 V - Maximum continuous reverse voltage before leakage exceeds 10 nA; sets upper limit for protected signal rail voltage. |
| VC @ IPP = 5 A | 13.5 V - Clamped voltage during 8/20 µs surge; determines peak stress on downstream IC input pins. |
| IPP | 22.7 A - Peak pulse current survivability per IEC 61000-4-2; defines robustness against worst-case ESD events. |
| C @ 0 V, 1 MHz | 65 pF - Signal-line capacitance; impacts high-speed interface integrity (e.g., USB 2.0, HDMI DDC, SDIO). |
| Response Time | <1 ns - Time to enter clamping state after ESD edge; critical for protecting nanosecond-scale CMOS inputs. |
| ESD Rating (HBM) | >16 kV - Human Body Model rating; qualifies for Class 3 ESD immunity in end-equipment certification. |
| Package | SOD-523 - 1.20 mm × 0.80 mm × 0.60 mm surface-mount outline; enables placement adjacent to connectors and ports. |
Pinout & Package
SOD-523 package: ultra-compact, two-terminal, surface-mount plastic case with cathode band marking; 100% matte tin lead finish; qualified for 260 °C reflow; MSL 1 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Protected Line Anode Connection | Connected to I/O line being protected; reverse-biased during normal operation; conducts during positive transients. |
| 2 (Anode) | GND Reference Terminal | Connected to system ground plane; provides low-inductance return path for ESD current; must be routed with minimal loop area. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 Level 4 Compliance | ±30 kV contact discharge protection - satisfies highest system-level ESD immunity requirement without external filtering. |
| Low Capacitance (65 pF) | Enables use on high-speed data lines (e.g., USB 2.0, eMMC, SD card interfaces) without signal integrity degradation. |
| Ultra-Fast Response (<1 ns) | Clamps before ESD energy couples into IC substrate; prevents latch-up and gate oxide damage in sub-micron CMOS. |
| Low Leakage Current (<10 nA @ 7.0 V) | Minimizes standby power loss and avoids false triggering in battery-powered sensor nodes and wearables. |
| Pb-Free & RoHS Compliant | Meets global environmental regulations; compatible with lead-free reflow profiles up to 260 °C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z7.0T1G | Same electrical specs and SOD-523 package; differs only in tape-and-reel quantity (3000 vs. 8000 units per reel). | No functional difference; suitable for same PCB layouts and assembly processes. | Select ESD5Z7.0T1G for lower-volume prototyping or when smaller reel size aligns with SMT line changeover frequency. |
| TPD2E001DRYR | Bi-directional, 15 pF capacitance, 12 V VRWM, 3.5 A IPP - lower clamping but higher stand-off voltage and much lower C. | Better suited for high-speed USB 2.0 or HDMI CEC lines where capacitance must stay below 20 pF. | Choose TPD2E001DRYR when protecting >480 Mbps differential signals; ESD5Z7.0T5G remains optimal for cost-sensitive, moderate-speed I/O with tighter VRWM margin. |
Compared with ESD5Z7.0T1G, the ESD5Z7.0T5G offers identical protection performance with higher reel quantity for production efficiency; versus TPD2E001DRYR, it trades lower capacitance for higher surge current handling and tighter 7.0 V VRWM alignment with 5 V logic rails.

FAQ
What is the maximum working voltage supported by the ESD5Z7.0T5G?
The ESD5Z7.0T5G has a working peak reverse voltage (VRWM) of 7.0 V, meaning it can continuously block up to 7.0 V in reverse bias without exceeding its specified leakage current of 10 nA. This makes ESD5Z7.0T5G appropriate for protecting 5 V logic rails and other interfaces where the steady-state signal swing remains below 7.0 V, while still providing headroom for transient overvoltage events.
Does the ESD5Z7.0T5G meet automotive qualification standards?
The ESD5Z7.0T5G is not AEC-Q101 qualified; however, the SZESD5Z7.0T5G variant - which shares identical electrical characteristics - is AEC-Q101 qualified and PPAP capable. For automotive applications requiring formal qualification, engineers should specify SZESD5Z7.0T5G instead of ESD5Z7.0T5G, as the base ESD5Z7.0T5G is intended for commercial and industrial portable equipment.
How does the clamping voltage of ESD5Z7.0T5G compare to similar 7 V-rated ESD diodes?
The ESD5Z7.0T5G delivers a clamping voltage of 13.5 V at 5 A (8/20 µs pulse), which is among the lowest in its class. This value is confirmed in the onsemi datasheet Table on page 3 and reflects actual oscilloscope-measured waveform performance per AND8307/D. Lower clamping directly reduces stress on protected IC inputs, improving long-term reliability under repeated ESD exposure compared to alternatives with VC > 15 V at same IPP.
Can ESD5Z7.0T5G be used for bidirectional signal lines like USB D+ and D−?
ESD5Z7.0T5G is unidirectional, so it protects only positive transients on a line referenced to ground. To protect bidirectional lines such as USB 2.0 D+ and D−, two ESD5Z7.0T5G devices must be placed in series opposition (anode-to-anode or cathode-to-cathode). This configuration achieves symmetrical ±13.5 V clamping while retaining the 65 pF capacitance and 7.0 V VRWM per polarity - a method validated in onsemi application notes for high-speed interfaces.
What is the thermal performance limit of ESD5Z7.0T5G during surge events?
The ESD5Z7.0T5G is rated for 500 mW total power dissipation on FR-4 board at 25 °C ambient, but its transient thermal performance is defined by peak power handling: 200 W at 8/20 µs pulse (per datasheet page 3). Its junction-to-ambient thermal resistance (RθJA) is not specified, but the SOD-523 package's small mass allows rapid heat dissipation during short-duration ESD events - enabling reliable operation even with repeated 22.7 A surges when mounted on standard 1 cm² copper pads.
