Product details
Overview
ESD8351XV2T5G from onsemi is a low-capacitance bidirectional ESD protection diode in SOD-523 package, designed for high-speed data lines including USB 2.0 and eSATA. It delivers 0.55 pF max junction capacitance, ±15 kV IEC 61000-4-2 contact ESD rating, 3.3 V reverse working voltage, 7.0 V typical breakdown voltage, and 8.2 V clamping voltage at 5 A peak pulse current.
For engineers reviewing the ESD8351XV2T5G datasheet, pinout, applications, or equivalent options, this device is selected for high-fidelity signal integrity preservation in 480 Mbps USB 2.0 interfaces where sub-0.6 pF loading and latch-up–free operation are mandatory design constraints.
Technical Context
The ESD8351XV2T5G uses a snap-back SCR-based structure optimized for fast transient response and low dynamic resistance (0.62 Ω anode-to-cathode), enabling robust clamping during IEC 61000-4-2 Level 4 events. Its bidirectional configuration protects both polarities of differential or single-ended high-speed lines without polarity dependency.
Designed specifically for latch-up–free operation in USB 2.0 HS (480 Mbps) and DisplayPort applications, it meets VHOLD ≥ 1.15 V and IHOLD = 20 mA thresholds validated per onsemi's load-line analysis methodology - excluding HDMI TMDS due to insufficient holding voltage margin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 3.3 V - matches USB 2.0 I/O rail voltage, ensuring no leakage or conduction during normal operation |
| Junction Capacitance | 0.55 pF max @ 1 MHz - preserves signal integrity up to 480 Mbps with minimal rise-time degradation |
| Clamping Voltage | 8.2 V @ 5 A, 8/20 µs - limits transient overvoltage to safe levels for downstream 3.3 V logic receivers |
| ESD Rating | ±15 kV contact per IEC 61000-4-2 Level 4 - exceeds industrial and automotive system-level immunity requirements |
| Breakdown Voltage | 7.0 V typical @ 1 mA - provides sufficient margin above 3.3 V rail while enabling early turn-on during transients |
| Dynamic Resistance | 0.62 Ω (anode-to-cathode) - reduces voltage overshoot during high di/dt ESD pulses |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD8004MUT5G | 0.35 pF max capacitance; lower 6.5 V clamping at 8 A; same SOD-523 package | Optimized for USB 2.0 LS/FS and HS; higher clamping margin at lower currents | Select when lowest possible signal loading is critical and system-level ESD stress is ≤ ±8 kV contact |

FAQ
What is the maximum junction capacitance of ESD8351XV2T5G and why does it matter for USB 2.0?
The ESD8351XV2T5G has a maximum junction capacitance of 0.55 pF at 1 MHz. This ultra-low value is critical for USB 2.0 high-speed (480 Mbps) operation because excessive capacitance degrades signal edge rates, increases bit error rate, and can cause eye diagram closure. The 0.55 pF spec ensures minimal loading on differential D+/D− lines while maintaining effective ESD clamping - a key trade-off addressed in the ESD8351XV2T5G's design.
Is ESD8351XV2T5G suitable for HDMI applications?
No, ESD8351XV2T5G is not recommended for HDMI 1.3a/1.4 TMDS applications. Per onsemi's latch-up analysis in the datasheet, its holding voltage (VHOLD = 1.15 V) falls below the 1.0 V minimum required for HDMI latch-up immunity. The ESD8104 or ESD8040 are explicitly validated for HDMI use. Using ESD8351XV2T5G in HDMI may result in destructive latch-up after ESD events.
What does the "SZ" prefix in SZESD8351XV2T5G indicate?
"SZ" denotes an onsemi automotive-grade variant of ESD8351XV2T5G, fully AEC-Q101 qualified and PPAP capable. It includes enhanced process controls, extended traceability, and site-specific change management - required for automotive infotainment, ADAS, and telematics systems. The SZESD8351XV2T5G shares identical electrical specs and SOD-523 packaging with the commercial ESD8351XV2T5G.
What is the clamping voltage of ESD8351XV2T5G at 5 A peak pulse current?
The ESD8351XV2T5G exhibits a clamping voltage of 8.2 V at 5 A peak pulse current (tp = 8/20 µs). This value is measured per IEC 61000-4-5 waveform conditions and represents the maximum voltage imposed on the protected line during a standardized surge event - ensuring downstream 3.3 V logic components remain within absolute maximum ratings.
Does ESD8351XV2T5G require external biasing or control signals?
No, ESD8351XV2T5G is a passive, bidirectional TVS diode requiring no external power, bias, or control signals. It operates solely based on voltage threshold conduction: remaining high-impedance below 3.3 V reverse working voltage, then snapping back to low-impedance clamping mode during ESD transients. Its two-terminal SOD-523 configuration simplifies PCB layout and eliminates system-level integration complexity.
