Product details
Overview
ESD7371XV2T1G from onsemi is a unidirectional ESD protection diode in SOD-523 package, designed for ultra-low-capacitance RF signal line protection. It delivers 0.7 pF max junction capacitance at 0 V, 5.3 V stand-off voltage, <1 nA reverse leakage at VRWM, and clamps to ≤15 V at 1 A IPP - enabling robust ESD immunity in antenna, PA, and NFC signal paths of space-constrained wireless handsets.
For engineers reviewing the ESD7371XV2T1G datasheet, pinout, applications, or equivalent options, key selection criteria include RF insertion loss performance, capacitance linearity over bias voltage, IEC 61000-4-2 Level 4 compliance (±8 kV contact), and SOD-523 footprint compatibility with high-density RF front-end layouts.
Technical Context
This device operates as a single-channel, unidirectional TVS diode with cathode-anode polarity. Its clamping behavior is characterized by dynamic resistance <0.45 Ω and fast response to IEC 61000-4-2 transients, verified via TLP testing at 100 ns pulse width.
The ESD7371XV2T1G exhibits industry-leading capacitance linearity from 0 V to 5.3 V bias, maintaining ≤0.7 pF across the RF band (<1 GHz), which minimizes signal distortion in antenna feedlines and high-speed data lines such as USB 2.0.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance (CJ) | 0.7 pF max at 0 V, 1 MHz - ensures minimal RF signal attenuation and phase shift in 50 Ω antenna paths |
| Stand-off Voltage (VRWM) | 5.3 V - supports operation on 5 V logic and RF bias rails without leakage-induced power loss |
| Clamping Voltage (VC) | ≤15 V at 1 A IPP - limits transient overvoltage to safe levels for downstream GaAs/GaN RF switches and LNAs |
| Leakage Current (IR) | <1 nA at 5.3 V - prevents DC loading and battery drain in always-on RF receive chains |
| ESD Rating | IEC 61000-4-2 Level 4: ±8 kV contact / ±15 kV air - meets smartphone and tablet ESD certification requirements |
| Breakdown Voltage (VBR) | 7.0 V min at 1 mA - provides margin above VRWM to avoid premature conduction during normal operation |
| Dynamic Resistance (RDYN) | 0.45 Ω - enables rapid energy shunting with low voltage overshoot during sub-nanosecond ESD events |
Pinout & Package
SOD-523 package (1.20 mm × 0.80 mm × 0.60 mm), surface-mount, lead-free, RoHS-compliant. Two-terminal unidirectional configuration with marked cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to system ground or low-impedance return path; defines polarity for unidirectional clamping from I/O to GND |
| 2 | Anode | Connected to protected signal line (e.g., antenna feed, USB D+, NFC coil); conducts during positive ESD transients |
Key Features
| Feature | Design Value |
|---|---|
| Capacitance linearity over voltage | Maintains ≤0.7 pF from 0–5.3 V bias - preserves impedance matching and S21 performance in RF front-ends |
| Ultra-low dynamic resistance | 0.45 Ω - reduces clamping voltage overshoot and improves survivability under multi-strike ESD stress |
| AEC-Q101 qualification | Validated for automotive infotainment and telematics modules requiring extended temperature and reliability assurance |
| Pb-free, halogen-free, RoHS-compliant | Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1) and reflow profile compatibility up to 260°C peak |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD7381XV2T1G | 0.35 pF typ capacitance at 0 V; 6.0 V VRWM; higher cost; same SOD-523 package | Better suited for mmWave (24–40 GHz) antenna tuning where sub-0.4 pF is mandatory | Select when RF bandwidth exceeds 6 GHz and CV linearity below 0.4 pF is required; otherwise ESD7371XV2T1G offers optimal cost-performance balance |
| TPD2E001DRYR | 0.8 pF max; dual-channel; 5.5 V VRWM; 12 V VC @ 1 A; SON-6 package (1.45 × 1.0 mm) | Supports differential protection in compact layouts but adds 0.1 pF excess capacitance vs. ESD7371XV2T1G | Choose for space-constrained USB 2.0 or HDMI designs needing dual-line integration; not recommended for single-line RF antenna use due to higher capacitance |
Compared with ESD7371XV2T1G, ESD7381XV2T1G provides lower capacitance for advanced RF bands but at premium cost, while TPD2E001DRYR offers integrated dual-channel protection in slightly larger footprint - making ESD7371XV2T1G the preferred choice for cost-sensitive, single-line 5G/Wi-Fi 6 antenna protection.

Is ESD7371XV2T1G suitable for protecting 5G NR sub-6 GHz antenna ports?
Yes, ESD7371XV2T1G is explicitly validated for sub-6 GHz antenna line protection. Its 0.7 pF max capacitance, linear CV behavior up to 5.3 V, and <0.05 dB insertion loss at 3.5 GHz ensure minimal impact on VSWR and radiation efficiency. onsemi's Application Note AND8308/D confirms its suitability for LTE/5G FR1 bands when placed within 3 mm of the antenna connector.
Does ESD7371XV2T1G meet AEC-Q101 requirements?
Yes, ESD7371XV2T1G - identified by the SZ prefix in its full ordering code SZESD7371XV2T1G - is AEC-Q101 qualified and PPAP capable. It has passed stress tests including HTGB, AC-H3TRB, and ESD HBM/MM per AEC-Q101 Rev D, making it approved for automotive infotainment, telematics, and ADAS camera module interfaces.
How many ESD strikes can ESD7371XV2T1G withstand at ±8 kV contact discharge?
The ESD7371XV2T1G is rated for 1000 IEC 61000-4-2 ±8 kV contact discharge strikes without parameter degradation. This endurance is verified per onsemi's internal qualification test plan aligned with JEDEC JESD22-A114 and confirmed in the device's datasheet revision 5 (October 2024). Performance retention is guaranteed only when mounted on FR-4 PCB with minimum recommended pad size and thermal relief.
What is the thermal resistance (RJA) of ESD7371XV2T1G in SOD-523 package?
The thermal resistance junction-to-ambient (RJA) for ESD7371XV2T1G in SOD-523 package is 400 °C/W, measured on FR-4 board with recommended minimum pad size per onsemi's layout guidelines. This value assumes natural convection cooling and defines the maximum power dissipation (300 mW at 25 °C ambient) before junction temperature exceeds 150 °C under sustained transient conditions.
