Product details
Overview
SZESD5Z5.0T5G from onsemi is a unidirectional ESD protection diode in SOD-523 package, featuring 5.0 V working peak reverse voltage (VRWM), 11.6 V clamping voltage at 5 A (VC), 80 pF capacitance at 0 V, IEC61000-4-2 Level 4 (±30 kV contact/air) compliance, and <1 ns response time - deployed for USB data lines, HDMI interfaces, and portable device I/O ports.
For engineers reviewing the SZESD5Z5.0T5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping performance under 5 A IEC 61000-4-2 transients, low capacitance for high-speed signal integrity, automotive-grade AEC-Q101 qualification, and SOD-523 footprint compatibility with space-constrained PCB layouts.
Technical Context
The SZESD5Z5.0T5G operates as a unidirectional transient voltage suppression diode, leveraging silicon avalanche structure to clamp fast-rising ESD pulses while maintaining low leakage (<50 nA at VRWM). Its design targets system-level I/O protection where signal bandwidth and board area are constrained.
It meets IEC61000-4-2 Level 4 (±30 kV contact/air), IEC61000-4-4 Level 4 (40 A EFT), and Human Body Model Class 3 (>16 kV), with thermal performance validated up to 150°C junction temperature and MSL 1 reflow compatibility at 260°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous reverse operating voltage before conduction begins; sets upper limit for protected line DC bias. |
| VC @ IPP = 5 A | 11.6 V - Clamping voltage during 8/20 µs surge; determines maximum stress imposed on downstream IC during ESD event. |
| C @ 0 V, 1 MHz | 80 pF - Junction capacitance at zero bias; directly impacts signal rise time degradation on high-speed interfaces like USB 2.0. |
| IR @ VRWM | 50 nA max - Reverse leakage current at rated standoff; ensures minimal power drain and signal distortion in battery-powered systems. |
| ESD Rating | ±30 kV per IEC61000-4-2 - Validated immunity level for direct contact discharge testing on end-product enclosures. |
| Response Time | <1 ns - Time to enter clamping state after ESD edge detection; critical for protecting sub-10 ns logic thresholds. |
| AEC-Q101 | Qualified - Confirmed reliability for automotive electronics including infotainment and body control modules. |
Pinout & Package
Package: SOD-523 (1.20 mm × 0.80 mm × 0.60 mm), surface-mount, void-free thermosetting plastic case with matte tin lead finish, MSL 1 rated, compatible with standard reflow profiles up to 260°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Protected Line Connection | Anode-side connection point for bidirectional protection configuration; polarity band identifies cathode for correct orientation on PCB. |
| 2 (Anode) | GND Reference | Low-impedance path to system ground during ESD event; must be routed with minimal inductance to maintain clamping efficacy. |
Key Features
| Feature | Design Value |
|---|---|
| Low Clamping Voltage | 11.6 V at 5 A enables robust protection of 3.3 V and 5 V logic without overvoltage damage to interface ICs. |
| Ultra-Small Footprint | 1.20 mm × 0.80 mm SOD-523 package saves >60% board area vs. SOT-23, enabling placement directly at connector pins. |
| Automotive Qualification | AEC-Q101 certification confirms suitability for under-hood and cabin electronics requiring extended temperature and lifetime validation. |
| High-Speed Signal Integrity | 80 pF capacitance supports USB 2.0 (480 Mbps) and HDMI 1.4 (up to 3.4 Gbps) without measurable eye diagram closure. |
| IEC61000-4-4 Compliance | 40 A EFT immunity ensures resilience against repetitive electrical fast transients in industrial and automotive power environments. |

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 (3,000 vs. 8,000 units) and absence of SZ-prefix. | Non-automotive commercial use; lacks AEC-Q101 documentation and PPAP capability. | Select when automotive qualification is not required and smaller reel size aligns with production batch volume. |
| TPD2E001DRYR | Bi-directional configuration; 10.5 V clamping at 5 A; 12 pF capacitance; 0.65 mm × 0.65 mm DRY package. | Better suited for AC-coupled or symmetric signal lines (e.g., USB Type-C CC lines); lower capacitance trades off higher clamping voltage. | Choose for ultra-high-speed interfaces where <15 pF is mandatory, accepting higher clamping voltage and bi-directional behavior. |
Compared with ESD5Z5.0T1G and TPD2E001DRYR, SZESD5Z5.0T5G uniquely combines automotive qualification, unidirectional operation for DC-biased lines, and optimal balance of 11.6 V clamping and 80 pF - making it preferred for cost-sensitive, space-constrained 5 V I/O protection in automotive and portable consumer designs.

FAQ
What is the clamping voltage of SZESD5Z5.0T5G under IEC61000-4-2 ESD stress?
The SZESD5Z5.0T5G exhibits a clamping voltage of 11.6 V at 5 A (8/20 µs pulse), measured per IEC61000-4-2 test conditions. This value represents the maximum voltage seen across the protected line during an ESD event and is confirmed in the official onsemi datasheet revision 16. The SZESD5Z5.0T5G maintains this performance across its full operating temperature range (−55°C to +150°C).
Is SZESD5Z5.0T5G suitable for protecting high-speed USB 2.0 signals?
Yes, SZESD5Z5.0T5G is appropriate for USB 2.0 data lines due to its 80 pF capacitance at 0 V and 11.6 V clamping voltage, both verified per onsemi's characterization. Its SOD-523 footprint allows placement directly at the USB connector, minimizing trace inductance. The SZESD5Z5.0T5G's <1 ns response time ensures protection before USB transceiver input stages are stressed.
Does SZESD5Z5.0T5G meet automotive qualification standards?
Yes, SZESD5Z5.0T5G is AEC-Q101 qualified and PPAP capable, as explicitly stated in the onsemi datasheet. The "SZ" prefix denotes automotive-grade manufacturing controls, site-specific change management, and extended reliability testing - distinguishing it from commercial-grade variants like ESD5Z5.0T1G. This makes SZESD5Z5.0T5G suitable for automotive infotainment, ADAS sensor interfaces, and body electronics.
What is the maximum working voltage supported by SZESD5Z5.0T5G?
The SZESD5Z5.0T5G has a working peak reverse voltage (VRWM) of 5.0 V, meaning it is designed to operate continuously at DC or peak AC voltages up to this level without entering conduction. It is intended for 5 V nominal systems such as USB host ports, HDMI hot-plug detect lines, and microcontroller GPIOs. Exceeding 5.0 V risks premature leakage or breakdown, so the SZESD5Z5.0T5G must be applied only in circuits with compatible bias conditions.
How does SZESD5Z5.0T5G differ from ESD5Z5.0T1G?
SZESD5Z5.0T5G and ESD5Z5.0T1G share identical electrical parameters and SOD-523 packaging but differ in qualification and packaging format: SZESD5Z5.0T5G carries the "SZ" prefix indicating AEC-Q101 qualification, PPAP capability, and automotive process controls, and ships in 8,000-unit tape-and-reel. ESD5Z5.0T1G is commercial-grade, shipped in 3,000-unit reels, and lacks formal automotive documentation. Both use the same SZESD5Z5.0T5G die and marking code "ZF".
