Product details
Overview
SZESD7361P2T5G from onsemi is a unidirectional ESD protection diode in SOD-923 package, designed for high-speed data line protection with 0.55 pF max junction capacitance, 5 V working peak reverse voltage, and ±15 kV IEC 61000-4-2 contact ESD immunity-used in NFC antenna interfaces and USB 2.0 signal lines.
For engineers reviewing the SZESD7361P2T5G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance for signal integrity, AEC-Q101 qualification for automotive-grade reliability, clamping voltage under 34 V at 16 A TLP, and SOD-923 footprint compatibility with space-constrained RF front-ends.
Technical Context
This device operates as a single-channel, unidirectional transient voltage suppressor optimized for bidirectional signal paths where ground-referenced clamping is required. Its low dynamic resistance (0.735 Ω) and sub-1 dB insertion loss up to 5 GHz ensure minimal distortion of high-frequency signals like NFC carrier waves (13.56 MHz) and USB 2.0 differential pairs (480 Mbps).
The SZESD7361P2T5G integrates a silicon avalanche structure with precise breakdown at 16.5 V (min), enabling robust protection while maintaining tight leakage control (<1 nA at 5 V VRWM). It meets ISO 10605 (330 pF/2 kΩ, ±15 kV) and IEC 61000-4-4 (40 A EFT), supporting system-level compliance in portable electronics without additional filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Junction Capacitance | 0.55 pF max at 0 V, 1 MHz - preserves signal integrity on >100 MHz data lines like NFC and USB 2.0 |
| Working Peak Reverse Voltage | 5 V - matches standard I/O voltage rails in mobile SoCs and PMICs |
| Clamping Voltage | 34 V at 16 A TLP - limits transient overvoltage to safe levels for downstream transceivers |
| ESD Immunity | ±15 kV contact per IEC 61000-4-2 - exceeds Level 4 requirement for handheld device ports |
| Breakdown Voltage | 16.5 V min at 1 mA - ensures reliable turn-on before damage threshold of protected ICs |
| Reverse Leakage | <1 nA at 5 V VRWM - avoids DC loading on sensitive analog or RF bias networks |
Pinout & Package
SZESD7361P2T5G is housed in the SOD-923 surface-mount package (0.80 × 0.60 × 0.37 mm), optimized for ultra-dense PCB layouts in smartphones and wearables.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected signal line; conducts during positive transients to clamp voltage to GND |

| Ultra-low capacitance | 0.55 pF enables use on 5 GHz-capable RF traces without degrading return loss or group delay |
| Low clamping voltage | 31 V at 8 A TLP ensures protected ICs remain below absolute maximum ratings during fast transients |
| Pb-free, RoHS compliant | Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1) for reflow compatibility without baking |
Applications
| NFC Antenna Interface | USB 2.0 Data Lines |
|---|---|
Use Scenario: Protecting 13.56 MHz NFC loop antenna traces from user-hand ESD during phone-to-card coupling. IC Role / Device Role / Timing Role: Unidirectional shunt protector placed between antenna feed point and NFC transceiver I/O pins. Use Value: 0.55 pF capacitance prevents detuning of LC resonance; ±15 kV ESD rating ensures field reliability across global consumer use cases. |
Use Scenario: Safeguarding D+ and D− differential pair in smartphone USB 2.0 OTG ports against cable-disconnect transients. IC Role / Device Role / Timing Role: Per-line ESD clamp mounted adjacent to connector to minimize trace inductance before protection. Use Value: Sub-1 dB insertion loss at 480 MHz preserves eye diagram integrity; 34 V clamping prevents PHY latch-up during hot-plug events. |
| Automotive Infotainment Display Port | Wireless Charging Receiver Coil Interface |
Use Scenario: Shielding MIPI DSI or LVDS video lines in center-stack displays from dashboard ESD events. IC Role / Device Role / Timing Role: Signal-line ESD suppressor placed at display connector entry point with shortest possible ground path. Use Value: AEC-Q101 qualification guarantees operation at 105 °C ambient; 5 V VRWM aligns with display driver I/O voltage domains. |
Use Scenario: Protecting resonant tank feedback sensing lines in Qi-compliant wireless charging receivers from coil-coupled transients. IC Role / Device Role / Timing Role: Low-capacitance clamp on voltage-sense node between receiver coil and AC-DC converter controller. Use Value: 0.55 pF avoids shifting 100–205 kHz resonant frequency; 16.5 V breakdown allows margin above 12 V sense rail. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD7361XV2T5G | SOD-523 package (1.0 × 0.6 × 0.4 mm); identical electrical specs but 0.1 mm wider than SOD-923 | Preferred for designs with moderate board density where SOD-523 placement tooling is already established | Select when footprint compatibility with legacy SOD-523 designs is prioritized over minimum size |
| CM1213A-03SO | 0.35 pF typical capacitance; 3.3 V VRWM; ±12 kV IEC 61000-4-2 contact rating | Better suited for low-voltage 3.3 V I/O rails and tighter capacitance budgets, but lower ESD rating | Choose only if system-level ESD testing confirms ±12 kV sufficiency and 3.3 V VRWM matches host interface |
Compared with SZESD7361P2T5G, ESD7361XV2T5G offers identical protection performance in a slightly larger footprint, while CM1213A-03SO trades ESD robustness for lower capacitance and voltage rating-making SZESD7361P2T5G optimal for 5 V, ±15 kV automotive and premium mobile applications demanding smallest possible size.

FAQ
What is the package type and dimensions of SZESD7361P2T5G?
SZESD7361P2T5G uses the SOD-923 package with mechanical dimensions of 0.80 mm × 0.60 mm × 0.37 mm. This ultra-compact footprint is specified in onsemi's CASE 514AB outline and supports fine-pitch automated placement in high-density mobile PCBs. The device features a cathode-marked Pin 1 and anode Pin 2 configuration.
Is SZESD7361P2T5G qualified for automotive applications?
Yes, SZESD7361P2T5G is AEC-Q101 qualified and PPAP capable, with operating junction temperature ranging from −55 °C to +125 °C. The "SZ" prefix explicitly denotes automotive-grade manufacturing controls, site-specific process validation, and enhanced reliability testing per onsemi's automotive quality standards.
What is the maximum clamping voltage for SZESD7361P2T5G under ESD stress?
SZESD7361P2T5G clamps to 34 V maximum at 16 A TLP pulse (100 ns, 50 Ω source), and 31 V at 8 A TLP. These values are measured using transmission line pulse methodology per ANSI/ESD STM5.5.1 and reflect real-world voltage limiting during fast-rising ESD events on protected signal lines.
Does SZESD7361P2T5G support both contact and air-gap ESD testing per IEC 61000-4-2?
Yes, SZESD7361P2T5G is rated for ±15 kV contact discharge and ±15 kV air-gap discharge per IEC 61000-4-2 Level 4. This dual-mode rating is confirmed in the Absolute Maximum Ratings table of the official datasheet (Rev. 6, February 2024) and validated through onsemi's certified ESD test lab.
How does the 0.55 pF capacitance of SZESD7361P2T5G impact high-frequency signal integrity?
The 0.55 pF typical junction capacitance of SZESD7361P2T5G introduces negligible impedance mismatch on RF and high-speed digital lines: insertion loss remains below 1 dB up to 5 GHz, and it avoids detuning of NFC antenna resonance at 13.56 MHz. This enables direct placement on signal paths without added matching networks.
