Product details
Overview
ESD7371XV2T5G from onsemi is a unidirectional ESD protection diode in SOD-523 package, designed for RF signal line protection with 0.7 pF max capacitance (I/O to GND), 5.3 V stand-off voltage, and ±8 kV IEC 61000-4-2 contact discharge rating. It protects antenna, USB 2.0/3.0, and NFC signal paths in space-constrained wireless handsets and terminals.
For engineers reviewing the ESD7371XV2T5G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance linearity over voltage, clamping performance at 1 A (11–15 V), dynamic resistance < 1 Ω, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a unidirectional transient voltage suppressor with cathode-anode polarity, optimized for high-frequency signal integrity. Its junction capacitance remains stable from 0 V to 5.3 V bias, enabling minimal RF insertion loss in antenna feedlines and front-end switching paths.
The ESD7371XV2T5G delivers fast response to ESD transients via low dynamic resistance (0.45 Ω typical) and sub-nA leakage (<1 nA at 5.3 V), ensuring minimal loading on sensitive RF ICs while maintaining robust ±8 kV IEC 61000-4-2 immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance (I/O–GND) | 0.7 pF max at 1 MHz; ensures negligible RF signal distortion in 2.4 GHz/5 GHz antenna lines |
| Stand-off Voltage | 5.3 V; blocks normal operating voltage while triggering only during ESD events |
| Clamping Voltage | 11–15 V at 1 A IPP; limits voltage seen by protected IC to safe levels during ESD strike |
| Leakage Current | <1 nA at 5.3 V; prevents DC bias shift or power drain in low-current RF circuits |
| Dynamic Resistance | 0.45 Ω typical; enables rapid voltage clamping with minimal overshoot under fast transients |
| ESD Rating | ±8 kV contact / ±15 kV air per IEC 61000-4-2 Level 4; meets industrial and automotive surge requirements |
| Breakdown Voltage | 7.0 V min at 1 mA; provides margin above stand-off voltage for reliable turn-on threshold |

Applications
| Antenna Line Protection | USB 2.0/3.0 Interface |
|---|---|
Use Scenario: Protecting cellular/Wi-Fi antenna feedlines in smartphones and IoT terminals from ESD damage during handling and operation. IC Role / Device Role / Timing Role: Unidirectional voltage clamp placed between RF switch output and antenna connector. Use Value: 0.7 pF capacitance avoids detuning of antenna resonance; 5.3 V stand-off allows uninterrupted RF transmission up to 5 V bias. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD7381XV2T5G | 0.35 pF typ capacitance (vs. 0.43 pF typ for ESD7371XV2T5G); same SOD-523 package and 5.3 V VRWM | Better suited for >6 GHz mmWave antenna lines where sub-0.4 pF is critical | Select when RF frequency exceeds 5 GHz and capacitance budget is ≤0.4 pF |
| CM1213-04SO | Quad-channel, 0.8 pF max per channel, SOIC-14 package; higher board footprint but supports four lines | Targets multi-line interfaces like HDMI or MIPI where discrete single-line devices increase layout complexity | Choose for space-tolerant designs requiring consolidated protection of ≥4 signal lines |
Compared with ESD7371XV2T5G, ESD7381XV2T5G offers lower capacitance for millimeter-wave use, while CM1213-04SO trades miniaturization for integration density-neither is pin-compatible, and both require PCB redesign for substitution.

FAQ
What is the primary circuit role of the ESD7371XV2T5G?
The ESD7371XV2T5G serves as a unidirectional ESD protection diode, placed between a sensitive RF or high-speed digital signal line and ground to clamp transient voltages during electrostatic discharge events. Its cathode connects to ground and anode to the protected line, enabling low-leakage operation below 5.3 V while triggering rapidly above that threshold. This function is confirmed in the datasheet's IV characteristics, pin configuration, and application diagrams for antenna and USB lines.
Is the ESD7371XV2T5G qualified for automotive applications?
Yes, the ESD7371XV2T5G carries the SZ prefix (SZESD7371XV2T5G), indicating AEC-Q101 qualification and PPAP capability. This certification validates its reliability under automotive temperature cycling (−55 °C to +150 °C), humidity, and mechanical stress conditions. The datasheet explicitly states "SZ Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements", confirming its suitability for infotainment, telematics, and ADAS antenna modules.
What is the maximum clamping voltage of the ESD7371XV2T5G at 1 A peak pulse current?
The ESD7371XV2T5G has a clamping voltage range of 11 V (typical) to 15 V (maximum) at 1 A peak pulse current (IPP = 1 A), per the Electrical Characteristics table. This value is measured using the IEC 61000-4-5 waveform and reflects the voltage drop across the device during an ESD event, directly limiting stress on downstream components such as RF switches or USB transceivers.
Does the ESD7371XV2T5G support bidirectional signal lines like USB D+ and D−?
Although the ESD7371XV2T5G is unidirectional, it can protect bidirectional lines like USB D+ and D− when used in pairs-one device per line-with cathodes tied to ground. The datasheet confirms this usage in "Typical Applications" and Figure 8's test setup, where each signal line uses a dedicated ESD7371XV2T5G to maintain low capacitance and avoid forward-bias conduction during normal signaling.
What package type and dimensions does the ESD7371XV2T5G use?
The ESD7371XV2T5G uses the SOD-523 package (Case 502), measuring 1.20 mm × 0.80 mm × 0.60 mm. This is confirmed in the Ordering Information table and Mechanical Case Outline drawing (Document 98AON11524D). The package features two terminals: pin 1 (cathode, marked with polarity band) and pin 2 (anode), and is Pb-free, halogen-free, and RoHS compliant.
