Product details
Overview
ESD5Z7.0T1G 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 ESD5Z7.0T1G datasheet, pinout, applications, or equivalent options, key selection criteria include IEC61000-4-2 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 ESD5Z7.0T1G implements a single unidirectional Zener-based clamping structure optimized for transient suppression on data lines with strict capacitance constraints. Its 7.0 V VRWM aligns with 5 V and 3.3 V logic rails, while 13.5 V VC at 5 A ensures downstream ICs remain below safe stress thresholds during IEC61000-4-2 events.
It delivers 200 W peak power dissipation under 8/20 µs surge conditions and meets Class 3 HBM ESD rating (>16 kV), with verified performance across −55 °C to +150 °C junction temperature range and Pb-free matte tin lead finish compatible with 260 °C reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 7.0 V - Maximum continuous reverse operating voltage before conduction; sets minimum system rail compatibility (e.g., 5 V USB, HDMI) |
| VC @ IPP = 5 A | 13.5 V - Clamped voltage during 8/20 µs surge; limits stress on protected IC inputs |
| IPP | 22.7 A - Peak pulse current handling per IEC61000-4-2; defines robustness against ±8 kV contact discharge |
| C @ 0 V, 1 MHz | 65 pF - Signal-line capacitance; enables use on high-speed interfaces like USB 2.0 and SD card lines |
| IR @ VRWM | 0.01 µA - Reverse leakage at rated standoff; preserves battery life in always-on portable circuits |
| Response Time | <1 ns - Enables sub-nanosecond turn-on to suppress ESD before sensitive logic is damaged |
| ESD Rating | Class 3 HBM (>16 kV), IEC61000-4-2 Level 4 (±30 kV contact) - Validated system-level immunity compliance |
Pinout & Package

Use Value: −55 °C to +150 °C operating range supports extended industrial ambient conditions; IEC61000-4-4 Level 4 EFT immunity adds surge resilience. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z7.0T5G | Same electrical specs and SOD-523 package; differs only in tape-and-reel quantity (8000 vs. 3000 units) | No functional difference; identical placement, soldering, and circuit behavior | Select based on volume procurement needs and line-side replenishment logistics |
| TPD2E001DRYR | Bi-directional, 10 pF capacitance, 12 V VRWM, 3.5 A IPP - lower clamping but higher capacitance sensitivity | Better suited for low-voltage, low-capacitance applications (e.g., MIPI D-PHY); not direct replacement due to bidirectional architecture | Choose TPD2E001DRYR only when bidirectional protection and sub-15 pF are mandatory; ESD5Z7.0T1G preferred for unidirectional 7 V rail alignment |
Compared with ESD5Z7.0T1G, ESD5Z7.0T5G offers identical protection performance in larger reels, while TPD2E001DRYR trades higher clamping margin for ultra-low capacitance - making ESD5Z7.0T1G optimal for cost-sensitive, unidirectional 5 V/7 V I/O protection where 65 pF is acceptable.

FAQ
What is the clamping voltage of ESD5Z7.0T1G at 5 A?
The ESD5Z7.0T1G has a specified clamping voltage (VC) of 13.5 V at 5 A peak pulse current under 8/20 µs waveform conditions. This value is measured per IEC61000-4-2 test methodology and ensures downstream ICs remain within safe operating limits during ESD events. The actual clamping voltage of ESD5Z7.0T1G may vary slightly with temperature and pulse shape but remains tightly controlled per onsemi's characterization data.
Is ESD5Z7.0T1G unidirectional or bidirectional?
ESD5Z7.0T1G is a unidirectional ESD protection diode, configured as a Zener clamp from cathode to anode. It conducts only during positive transients on the cathode side relative to anode (ground), making it ideal for protecting lines referenced to a fixed supply rail. This architecture differs from bidirectional devices like TPD2E001DRYR and is clearly indicated by its marking code "ZH" and polarity band on pin 1 in the SOD-523 package.
What package type does ESD5Z7.0T1G use?
ESD5Z7.0T1G uses the SOD-523 package (Case 502, Style 1), measuring 1.20 mm × 0.80 mm × 0.60 mm with a 0.7 mm maximum body height. It features a cathode-marked pin 1, matte tin lead finish, UL 94 V-0 compliant epoxy, and meets MSL 1 moisture sensitivity level - enabling standard Pb-free reflow without baking.
Does ESD5Z7.0T1G meet IEC61000-4-2 Level 4?
Yes, ESD5Z7.0T1G is certified to IEC61000-4-2 Level 4, supporting ±30 kV contact discharge and ±30 kV air discharge. This compliance is validated per the test setup and waveform definitions in Figures 3–4 of the official onsemi datasheet, and confirmed by oscilloscope screenshots (Figures 1–2) showing clamping behavior under 8 kV contact pulses. ESD5Z7.0T1G achieves this without derating or external components.
What is the maximum operating temperature range for ESD5Z7.0T1G?
The ESD5Z7.0T1G is rated for a junction and storage temperature range of −55 °C to +150 °C. This wide thermal envelope supports deployment in automotive cabin modules, industrial controllers, and outdoor portable equipment. The device maintains full ESD protection performance across this range, with parameters such as VRWM and VC characterized at TA = 25 °C and validated for stability over temperature per onsemi's qualification testing.
