Product details
Overview
ESD7351P2T5G from onsemi is a unidirectional ESD protection diode in SOD-923 package, featuring 3.3 V stand-off voltage, 0.43–0.6 pF junction capacitance (at 0 V, 1 MHz to <1 GHz), <1 ns response time, and IEC 61000-4-2 Level 4 (±20 kV contact/air) compliance - designed for RF signal line protection in space-constrained high-frequency interfaces.
For engineers reviewing the ESD7351P2T5G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance for antenna/USB 2.0 high-speed lines, clamping voltage under 10 V at 3 A, AEC-Q101 qualification for automotive use, and SOD-923 footprint compatibility with board-area-sensitive layouts.
Technical Context
This device operates as a single-channel, unidirectional transient voltage suppressor with cathode-anode polarity. Its low dynamic resistance (<0.35 Ω) and fast TLP response enable effective clamping of ESD pulses before sensitive RF ICs experience overvoltage stress.
The ESD7351P2T5G is optimized for signal integrity preservation: junction capacitance remains stable below 0.6 pF up to 1 GHz, and insertion loss stays under −2 dB across 100 MHz–3 GHz - critical for antenna feedline and NFC front-end protection where impedance matching must be maintained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage | 3.3 V - blocks normal operating voltage while remaining non-conductive during system operation. |
| Junction Capacitance | 0.43–0.6 pF @ 0 V, 1 MHz to <1 GHz - preserves signal integrity in USB 2.0 and RF antenna paths without loading. |
| Clamping Voltage | 8.0 V @ 1 A, 10 V @ 3 A - limits transient voltage seen by downstream RF switch or PA to safe levels during ESD events. |
| Response Time | <1 ns - activates before ESD pulse peak reaches protected circuitry, preventing latch-up or gate oxide damage. |
| ESD Rating | IEC 61000-4-2 Level 4: ±20 kV contact / ±20 kV air - meets highest system-level ESD immunity requirement for consumer and automotive end equipment. |
| Dynamic Resistance | <0.35 Ω - minimizes voltage overshoot during high-current transients by reducing IR drop across the protection path. |
Pinout & Package
SOD-923 (Case 514AB) surface-mount package: 0.80 mm × 0.60 mm × 0.37 mm, anode-cathode dual-terminal configuration with polarity band marking on cathode side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | ESD current sink node | Connected to protected I/O line; conducts transient current to GND when voltage exceeds VRWM + VBR. |
| 2 (Anode) | Reference/GND return path | Must be connected to low-impedance system ground to complete clamping path and minimize loop inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.43 pF typical at 0 V, 1 MHz - enables use on 480 Mbps USB 2.0 differential pairs without signal degradation. |
| AEC-Q101 qualified | Validated for automotive applications including infotainment antenna ports and telematics RF modules. |
| Low clamping voltage | 8.0 V at 1 A IPP - protects 3.3 V logic-level RF switches and LNA inputs from destructive overvoltage. |
| Pb-free, RoHS-compliant | Meets J-STD-609 Category 1 moisture sensitivity and IPC/JEDEC J-STD-020 reflow profile requirements. |
Applications
| RF Antenna Line Protection | USB 2.0 High-Speed Data Lines |
|---|---|
Use Scenario: Protecting cellular/Wi-Fi/GNSS antenna feedlines from ESD discharge during handling or connector mating. IC Role / Device Role / Timing Role: Unidirectional voltage clamp placed between antenna port and RF switch/LNA input. Use Value: Maintains sub-0.6 pF capacitance to avoid detuning antenna resonance and degrading return loss (S11). |
Use Scenario: Safeguarding D+ and D− pins of USB 2.0 transceivers against user-port ESD events. IC Role / Device Role / Timing Role: Low-capacitance shunt diode on each data line referenced to chassis ground.

IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional diode (cathode to I/O, anode to GND) on NFC data and clock lines. Use Value: Ensures <0.5 dB insertion loss at 13.56 MHz and preserves near-field coupling efficiency without adding parasitic capacitance. |
Use Scenario: ESD hardening of AM/FM/DAB antenna inputs and tuner signal paths in automotive head units. IC Role / Device Role / Timing Role: AEC-Q101-qualified transient suppressor on RF front-end signal chains prior to tuner ICs. Use Value: Guarantees robustness against ISO 10605 and IEC 61000-4-2 ESD stress in harsh vehicle environments without compromising RF sensitivity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD7351XV2T5G | SOD-523 package (1.20 × 0.80 mm); identical electrical specs but larger footprint than SOD-923. | Preferred where board assembly uses standard SOD-523 pick-and-place tooling or thermal relief requires slightly higher power dissipation margin. | Select ESD7351XV2T5G only if SOD-923 placement is incompatible with existing stencil or reflow profile. |
| CM1213A-03SR | 0.5 pF max capacitance, 3.3 V VRWM, but rated for 12 kV IEC 61000-4-2 (Level 3), not Level 4. | Suitable for cost-sensitive consumer electronics where ±15 kV ESD immunity suffices, not automotive or industrial-grade systems. | Choose CM1213A-03SR only when Level 4 immunity is not required and SOD-923 footprint compatibility is secondary to procurement availability. |
Compared with ESD7351XV2T5G and CM1213A-03SR, the ESD7351P2T5G delivers the smallest PCB footprint (0.80 × 0.60 mm), full Level 4 ESD robustness, and verified RF performance up to 3 GHz - making it the optimal choice for next-generation compact wireless modules requiring both miniaturization and automotive-grade reliability.

FAQ
What is the maximum clamping voltage of the ESD7351P2T5G at 3 A transient current?
The ESD7351P2T5G exhibits a maximum clamping voltage of 10 V when subjected to a 3 A peak pulse current (IPP = 3 A), per its Electrical Characteristics table. This value ensures downstream 3.3 V RF components remain within safe operating voltage margins during severe ESD events, and is measured using the IEC 61000-4-2 waveform-equivalent TLP test method. The ESD7351P2T5G maintains this performance consistently across its operating temperature range of −55 °C to +150 °C.
Is the ESD7351P2T5G suitable for protecting USB 2.0 high-speed differential pairs?
Yes, the ESD7351P2T5G is explicitly validated for USB 2.0 high-speed (480 Mbps) data line protection due to its 0.43–0.6 pF junction capacitance and <−2 dB insertion loss up to 3 GHz. Its low dynamic resistance (<0.35 Ω) prevents signal reflection and eye diagram distortion. The ESD7351P2T5G must be placed as close as possible to the USB connector with symmetric layout to preserve differential impedance - confirmed in onsemi Application Note AND8308/D.
Does the ESD7351P2T5G meet automotive qualification standards?
Yes, the ESD7351P2T5G carries the SZ prefix (SZESD7351P2T5G) and is AEC-Q101 qualified for automotive applications, with PPAP capability. It supports operation from −55 °C to +150 °C junction temperature and passes IEC 61000-4-2 Level 4 (±20 kV contact/air) testing - making it suitable for antenna ports, tuner inputs, and RF modules in automotive infotainment and telematics systems.
What is the package type and dimensions of the ESD7351P2T5G?
The ESD7351P2T5G is packaged in SOD-923 (Case 514AB), measuring 0.80 mm × 0.60 mm × 0.37 mm. This ultra-compact two-terminal surface-mount package features a cathode polarity band on pin 1 and is optimized for high-density PCB layouts. Its small size reduces parasitic inductance, enhancing high-frequency ESD suppression performance - distinct from the larger SOD-323 and SOD-523 variants in the same series.
How does the ESD7351P2T5G compare to generic TVS diodes in RF applications?
Unlike general-purpose TVS diodes with >10 pF capacitance, the ESD7351P2T5G delivers 0.43–0.6 pF capacitance - over 15× lower - enabling use on RF antenna lines and high-speed serial interfaces without degrading return loss or group delay. Its <1 ns response time and <0.35 Ω dynamic resistance provide superior transient suppression fidelity. The ESD7351P2T5G is engineered specifically for signal integrity preservation, whereas generic TVS diodes prioritize power handling over RF performance.
