Product details
Overview
ESD5Z7.0T1 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 ESD5Z7.0T1 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
This device operates as a unidirectional transient voltage suppressor, leveraging silicon avalanche breakdown to clamp ESD transients before they reach downstream ICs. Its low 7.0 V stand-off voltage ensures compatibility with 3.3 V and 5 V logic rails while maintaining margin against normal operating voltage excursions.
Clamping performance is validated per IEC 61000-4-2 (±30 kV contact/air) and IEC 61000-4-4 (40 A EFT), with peak power dissipation of 200 W under 8/20 µs surge. The SOD-523 package enables placement directly at connector or port entry points without compromising board space.
Key Specifications

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; 8000 pcs/reel vs. 3000 pcs/reel packaging | No functional difference; suited for high-volume production runs requiring larger reels | Select ESD5Z7.0T5G when optimizing for automated assembly throughput and reduced reel change frequency |
| TPD2E001DRYR | Bi-directional, 10 pF capacitance, 12 V clamping at 1 A, SOT-553 package | Better for ultra-high-speed lines (e.g., USB 3.0); lower clamping but higher VRWM (5.5 V) | Choose TPD2E001DRYR where sub-15 pF capacitance is mandatory and 5.5 V stand-off suffices |
Compared with ESD5Z7.0T1, ESD5Z7.0T5G offers identical protection performance with higher reel quantity, while TPD2E001DRYR trades higher stand-off margin for significantly lower capacitance - making it preferable for >1 Gbps serial links but unsuitable for 7 V rail protection.

FAQ
What is the maximum working voltage supported by ESD5Z7.0T1?
The ESD5Z7.0T1 has a working peak reverse voltage (VRWM) of 7.0 V, meaning it reliably blocks up to 7.0 V in normal operation while remaining fully functional. This makes ESD5Z7.0T1 appropriate for protecting 3.3 V and 5 V digital interfaces where transient overvoltage must be clamped without interfering with steady-state signaling. Exceeding 7.0 V continuously risks increased leakage or premature conduction.
Does ESD5Z7.0T1 meet automotive qualification standards?
The base ESD5Z7.0T1 is not AEC-Q101 qualified; however, its automotive-grade variant SZESD5Z7.0T1G is explicitly listed in the datasheet as AEC-Q101 qualified and PPAP capable. ESD5Z7.0T1 itself is intended for commercial and industrial portable applications. For automotive use, designers must specify the SZ-prefix version to ensure compliance with automotive reliability and change control requirements.
What is the clamping voltage of ESD5Z7.0T1 under real ESD stress?
The ESD5Z7.0T1 clamps to 13.5 V when subjected to a 5 A IEC 61000-4-2 compliant transient, and up to 22.7 V at its maximum rated peak pulse current of 22.7 A. These values are measured using the standardized 8/20 µs waveform and reflect actual voltage seen by the protected IC during an ESD event - critical for verifying margin against downstream component absolute maximum ratings.
Can ESD5Z7.0T1 be used for bidirectional signal lines like USB D+ and D−?
ESD5Z7.0T1 is unidirectional and must be used in pairs (anode-to-ground + cathode-to-signal) or with a complementary diode to protect bidirectional lines. For native bidirectional protection, onsemi offers the ESD7XXX series or alternatives like TPD2E001DRYR. Using a single ESD5Z7.0T1 on a bidirectional line leaves negative transients unprotected unless combined with proper grounding topology.
What is the thermal limit for ESD5Z7.0T1 during reflow soldering?
ESD5Z7.0T1 is rated for a maximum lead solder temperature of 260 °C for 10 seconds and meets J-STD-020 Moisture Sensitivity Level 1 (MSL 1), meaning it can be stored indefinitely at ≤30 °C/85% RH without baking. Its thermosetting plastic package and matte tin finish ensure reliable performance through standard lead-free reflow profiles without delamination or voiding.
