Product details
Overview
SZESD5Z6.0T5G from onsemi is a unidirectional ESD protection diode in SOD-523 package, designed to clamp transient voltages to 12.4 V at 5 A and 20.5 V at maximum peak pulse current, with 6.0 V working peak reverse voltage, 0.01 µA max reverse leakage at VRWM, and 70 pF typical capacitance - deployed for I/O line protection in portable USB, HDMI, and audio interfaces.
For engineers reviewing the SZESD5Z6.0T5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under IEC 61000-4-2 Level 4 (±30 kV contact), AEC-Q101 qualification for automotive use, low 1.20 mm × 0.80 mm footprint, and verified 16 kV HBM ESD rating.
Technical Context
This device operates as a unidirectional TVS diode, leveraging silicon avalanche breakdown to divert ESD transients away from sensitive ICs. Its clamping behavior is characterized at defined IEC 61000-4-2 8/20 µs surge conditions, with guaranteed VC ≤ 20.5 V at max IPP and response time < 1 ns.
The SZESD5Z6.0T5G integrates into high-density PCB layouts where board space is constrained, supporting fast transient suppression on data lines without signal integrity degradation due to its 70 pF capacitance and low forward voltage (VF ≤ 1.1 V @ 10 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 6.0 V - Maximum continuous reverse operating voltage before significant leakage begins; sets upper limit for protected signal rail voltage. |
| VC @ IPP = 5 A | 12.4 V - Clamped voltage during 5 A IEC 61000-4-2 pulse; determines maximum stress on downstream IC input pins. |
| VC @ Max IPP | 20.5 V - Peak clamping voltage at full rated surge current; defines worst-case overvoltage exposure during extreme ESD events. |
| IR @ VRWM | 0.01 µA - Reverse leakage at rated standoff voltage; ensures minimal power drain and signal distortion on high-impedance lines. |
| C @ 0 V, 1 MHz | 70 pF - Junction capacitance at zero bias; impacts high-speed signal integrity on interfaces like USB 2.0 or HDMI. |
| ESD Rating (HBM) | Class 3 (>16 kV) - Validated human-body-model robustness; meets stringent end-equipment immunity requirements. |
| IEC 61000-4-2 Level | Level 4 (±30 kV contact) - Highest system-level ESD immunity grade; qualifies for industrial and automotive front-panel interfaces. |

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 | Same electrical specs and SOD-523 package; differs only in tape-and-reel quantity (3000 vs. 8000 units per reel) and marking (T1G vs. T5G). | No functional difference; T1G used for smaller-batch prototyping, T5G optimized for high-volume production runs. | Select SZESD5Z6.0T5G when sourcing for automated SMT assembly with bulk reel feeders requiring 8000-unit reels. |
| TPD2E001DRYR | Bi-directional dual-channel ESD array (2×), 6.8 V VRWM, 12.5 V VC @ 5 A, 12 pF typical capacitance - lower C but higher VRWM and different polarity. | Designed for differential or dual-line protection (e.g., USB D+/D− together); not drop-in for single-line unidirectional use. | Choose TPD2E001DRYR only when protecting two closely coupled signals simultaneously and ultra-low capacitance (<15 pF) is mandatory. |
Compared with ESD5Z6.0T1G, SZESD5Z6.0T5G offers identical protection performance with optimized packaging for volume manufacturing; versus TPD2E001DRYR, it trades lower capacitance for simpler single-line integration, fixed unidirectional polarity, and AEC-Q101 qualification.

FAQ
What is the clamping voltage of SZESD5Z6.0T5G at 5 A peak pulse current?
The SZESD5Z6.0T5G has a maximum clamping voltage (VC) of 12.4 V at 5 A peak pulse current under IEC 61000-4-2 test conditions. This value is measured with an 8/20 µs current waveform and ensures protected circuits experience limited overvoltage during common ESD events. The SZESD5Z6.0T5G maintains this performance across its qualified temperature range.
Is SZESD5Z6.0T5G qualified for automotive applications?
Yes, SZESD5Z6.0T5G is AEC-Q101 qualified and PPAP capable, making it suitable for automotive infotainment, body electronics, and ADAS subsystems. Its construction meets automotive reliability standards, including operation from −55 °C to +150 °C junction temperature and resistance to mechanical shock and thermal cycling per AEC-Q101 test requirements.
What package type does SZESD5Z6.0T5G use, and what are its dimensions?
SZESD5Z6.0T5G uses the SOD-523 (Case 502) package, measuring 1.20 mm × 0.80 mm × 0.60 mm. It features a cathode band marking on pin 1, matte tin lead finish, and complies with MSL 1 moisture sensitivity level - enabling standard reflow soldering without baking.
How does the capacitance of SZESD5Z6.0T5G affect high-speed signal lines?
SZESD5Z6.0T5G exhibits 70 pF typical junction capacitance at 0 V and 1 MHz, which is optimized for USB 2.0 (480 Mbps), HDMI DDC, and audio interfaces where moderate bandwidth preservation is required. While not suited for USB 3.x or PCIe, this capacitance avoids excessive signal attenuation or rise-time degradation on sub-100 MHz digital and analog lines.
What is the difference between SZESD5Z6.0T5G and ESD5Z6.0T1G?
SZESD5Z6.0T5G and ESD5Z6.0T1G share identical electrical specifications, thermal ratings, and SOD-523 packaging. The distinction lies solely in packaging format: SZESD5Z6.0T5G ships in 8000-unit tape-and-reel reels, while ESD5Z6.0T1G uses 3000-unit reels. Both are Pb-free and RoHS compliant.
