Product details
Overview
SZESD7371P2T5G from onsemi is a unidirectional ESD protection diode array designed for high-speed data lines including USB 2.0, HDMI, and DisplayPort interfaces. It features a 3.3 V working voltage, 12 A peak pulse current (8/20 µs), 0.55 pF typical capacitance per line, and ±15 kV air-gap ESD immunity per IEC 61000-4-2.
For engineers reviewing the SZESD7371P2T5G datasheet, SZESD7371P2T5G pinout, SZESD7371P2T5G application, or SZESD7371P2T5G equivalent, key selection criteria include low capacitance for signal integrity, bidirectional clamping capability, compact SOT-553 package footprint, and compliance with IEC 61000-4-2 Class 4 and ISO 10605 standards.
Technical Context
This device integrates four independent ESD protection channels in a single monolithic silicon structure, each featuring a low-capacitance PN junction clamp to ground. It operates with a reverse standoff voltage of 3.3 V and triggers at 5.5 V (typical) under transient conditions.
The architecture supports fast response time (<1 ns) and low dynamic resistance (<0.5 Ω), enabling effective suppression of ESD transients without distorting high-frequency signals up to 5 Gbps. Its thermal design sustains repeated 12 A pulses without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 3.3 V - Matches standard I/O rail voltage for USB/HDMI PHY interfaces. |
| ESD Rating | ±15 kV air, ±8 kV contact (IEC 61000-4-2) - Full Class 4 system-level protection. |
| Capacitance | 0.55 pF per channel (at 1 MHz) - Preserves signal integrity on 480 Mbps USB 2.0 and 2.25 Gbps HDMI 1.3 lines. |
| Peak Pulse Current | 12 A (8/20 µs) - Handles multiple ESD events without parametric shift. |
| Clamping Voltage | 12 V at 12 A - Limits downstream IC stress below safe threshold for 3.3 V logic. |
| Leakage Current | 100 nA max at 3.3 V - Negligible impact on bus power budget and standby current. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O Channel 1 Anode | Input node for first protected signal line (e.g., USB D+). |
| 2 | GND | Common ESD return path and thermal anchor via exposed pad. |
| 3 | I/O Channel 2 Anode | Input node for second protected signal line (e.g., USB D−). |
| 4 | I/O Channel 3 Anode | Input node for third protected signal line (e.g., HDMI TMDS Data0+). |
| 5 | I/O Channel 4 Anode | Input node for fourth protected signal line (e.g., HDMI TMDS Data0−). |
Key Features
| Feature | Design Value |
|---|---|
| Low Capacitance | 0.55 pF per channel enables use on 5 Gbps differential interfaces without measurable eye closure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DRYR | 0.6 pF capacitance, 3.6 V working voltage, ±12 kV air ESD rating | Limited to USB 2.0 and lower-speed interfaces; not validated for HDMI 2.0 or DP 1.4 | Select when cost sensitivity outweighs need for HDMI 1.4/DP 1.2a support. |
| ESD5Z3.3T5G | Single-channel, 0.45 pF, same 3.3 V working voltage but no multi-line integration | Requires 4× placement and routing area; increases BOM count and assembly steps | Choose only if discrete layout control or failure isolation per line is required. |
Compared with TPD4E001DRYR and ESD5Z3.3T5G, SZESD7371P2T5G delivers higher ESD robustness and integrated 4-channel layout efficiency-critical for space-constrained high-speed video interfaces where board area and signal fidelity are co-constrained.

FAQ
What is the maximum data rate supported by SZESD7371P2T5G without signal degradation?
SZESD7371P2T5G supports data rates up to 5 Gbps on differential pairs, verified via eye diagram testing at 2.5 GHz fundamental frequency. Its 0.55 pF capacitance introduces <0.1 dB insertion loss at 2.5 GHz and maintains >30% eye height margin for HDMI 1.4 and DisplayPort 1.2a compliance.
Does SZESD7371P2T5G require an external bias or control signal?
No. SZESD7371P2T5G is a passive, diode-based ESD suppressor with no enable pin, supply rail, or configuration interface. It operates automatically upon transient detection and requires zero PCB routing for control logic or power sequencing.
Can SZESD7371P2T5G be used on bidirectional data lines like I²C or SPI?
No. SZESD7371P2T5G is unidirectional and configured for I/O-to-ground clamping only. For bidirectional buses such as I²C, a symmetric dual-diode array like NUP4201MR6T1G is required to protect both positive and negative transients.
How does the SOT-553 package affect thermal performance during repeated ESD strikes?
The SOT-553 package includes an exposed thermal pad that lowers junction-to-board thermal resistance to 120°C/W. Under 12 A, 8/20 µs pulses at 1 Hz, this allows ≤15°C junction temperature rise per event, ensuring no cumulative thermal stress across 1,000+ strikes per IEC 61000-4-2 testing.
