Product details
Overview
SZESD7361XV2T5G from onsemi is a unidirectional ESD protection diode in SOD−523 package, designed for high-speed data lines including NFC and wireless charging interfaces. It delivers 0.55 pF max junction capacitance, ±15 kV IEC 61000−4−2 contact ESD protection, and 31 V clamping voltage at 8 A peak pulse current.
For engineers reviewing the SZESD7361XV2T5G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance for signal integrity, AEC−Q101 qualification for automotive use, and verified clamping performance under IEC 61000−4−2/−4−4/−4−5 stress conditions.
Technical Context
This device operates as a single-channel, unidirectional transient voltage suppressor with cathode-anode polarity. Its low dynamic resistance (0.735 Ω) and sub-1 dB insertion loss up to 5 GHz ensure minimal signal distortion on high-speed differential or single-ended lines.
The SZESD7361XV2T5G is rated for −55 °C to +125 °C operating junction temperature and supports 5 V to 16 V working reverse voltage. It meets ISO 10605 (330 pF/2 kΩ, ±15 kV contact) and IEC 61000−4−5 (1 A, 8/20 µs) surge immunity requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD7361XV2T1G | Same die, identical electrical specs, but supplied in 3,000-piece tape & reel vs. 8,000-piece for SZESD7361XV2T5G | No functional difference; suited for prototyping or low-volume production runs | Select when smaller reels align with SMT line changeover frequency or inventory turnover targets |
| TPD1E05U06DPYR | 0.45 pF typical capacitance, 22 V clamping @ 8 A, 5.5 V VRWM - lower clamping but narrower voltage range | Better for 3.3 V-only systems (e.g., wearables); not rated for 12 V automotive rails or ISO 10605 | Choose only if system VRWM ≤ 5.5 V and clamping below 25 V is prioritized over multi-rail compatibility |
Compared with SZESD7361XV2T5G, ESD7361XV2T1G offers identical protection performance in a smaller reel format, while TPD1E05U06DPYR trades wider voltage coverage and automotive qualification for marginally lower capacitance and clamping - making it unsuitable for 12 V or ISO 10605–compliant designs.

FAQ
What is the maximum clamping voltage of SZESD7361XV2T5G under IEC 61000−4−2 stress?
The SZESD7361XV2T5G exhibits a clamping voltage of 31 V at 8 A peak pulse current and 34 V at 16 A, measured per TLP methodology aligned with IEC 61000−4−2 waveform characteristics. This value is confirmed in the Electrical Characteristics table of the official onsemi datasheet (Rev. 6, Feb 2024) and applies directly to the SZESD7361XV2T5G device in SOD−523 package.
Is SZESD7361XV2T5G suitable for automotive applications?
Yes, SZESD7361XV2T5G is AEC−Q101 qualified and PPAP capable, with the "SZ" prefix explicitly indicating compliance for automotive and other applications requiring controlled site and change management. Its −55 °C to +125 °C operating junction temperature range and ISO 10605 (±15 kV) rating validate its use in automotive infotainment, telematics, and body electronics.
What package type does SZESD7361XV2T5G use, and what are its dimensions?
SZESD7361XV2T5G uses the SOD−523 package (Case 502), with mechanical dimensions of 1.25 mm × 0.85 mm × 0.65 mm. This ultra-compact outline is documented in the onsemi mechanical drawings (Document 98AON23284D) and enables placement directly adjacent to high-speed connectors without compromising PCB layout density.
Does SZESD7361XV2T5G support bi-directional ESD protection?
No, SZESD7361XV2T5G is a unidirectional ESD protection diode, configured with cathode (pin 1) connected to the protected line and anode (pin 2) tied to ground. It conducts only during positive transients on the line relative to ground - appropriate for DC-biased or single-polarity signal paths like NFC antenna feeds or USB D+.
How does the 0.55 pF capacitance of SZESD7361XV2T5G impact high-frequency signal integrity?
The 0.55 pF maximum junction capacitance of SZESD7361XV2T5G results in less than 0.1 dB insertion loss at 2.4 GHz and maintains signal fidelity on 13.56 MHz NFC, 480 MHz USB 2.0, and 1.5 GHz MIPI D-PHY links. This value is measured at 0 V bias and 1 MHz, and remains stable up to 1 GHz per onsemi's CV characterization curves.
