Product details
Overview
SZESD7102BT1G from onsemi is a low-capacitance bidirectional ESD protection diode array in SC-75 package, designed for high-speed differential data lines. It delivers 0.3 pF typical junction capacitance (I/O to GND), 34 V typical clamping voltage at ±8 A TLP, and supports IEC 61000-4-2 Level 4 (±8 kV contact) protection - enabling robust signal integrity in USB 3.0 and HDMI interfaces.
For engineers reviewing the SZESD7102BT1G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance matching, differential pair symmetry, clamping voltage under TLP stress, and AEC-Q101 qualification for automotive-grade deployment.
Technical Context
The SZESD7102BT1G integrates two matched ESD protection diodes in a single SC-75 3-pin flow-through configuration, with Pin 1 and Pin 3 as I/O terminals and Pin 2 as common GND. Its symmetrical layout preserves impedance balance across high-speed differential pairs.
It operates across −55 °C to +150 °C junction temperature, supports 5 GHz 3dB bandwidth, and exhibits ≤0.2 dB insertion loss at 3 GHz - confirming suitability for 5 Gb/s USB 3.0 eye diagram preservation per Figure 11 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance (I/O–GND) | 0.3 pF typical - minimizes signal distortion on 5 Gb/s differential links |
| Clamping Voltage (±8 A TLP) | 34 V typical - limits transient overvoltage to protect downstream 16 V-rated transceivers |
| Reverse Working Voltage | 16 V - sets maximum DC bias before leakage rise, aligning with USB 3.0 VBUS margin |
| IEC 61000-4-2 Rating | ±8 kV contact - meets industrial and automotive system-level ESD immunity requirements |
| 3dB Bandwidth | 5 GHz - ensures full passband coverage for USB 3.0 Gen1 signaling without attenuation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD7102BT1G | Same die, non-automotive grade; no AEC-Q101 validation | Industrial/commercial use only; not qualified for automotive production | Select when AEC-Q101 is not required and cost sensitivity is higher |
| TPD2EUSB30DRYR | 0.35 pF typical capacitance; 3.6 V working voltage; 3-channel array | Targeted for USB 3.0 with integrated VBUS protection; lower voltage rating limits use with 5 V tolerant interfaces | Choose when VBUS line protection is needed alongside data-line clamping |
Compared with ESD7102BT1G and TPD2EUSB30DRYR, SZESD7102BT1G uniquely combines AEC-Q101 qualification, 16 V VRWM, and matched dual-channel architecture - making it the only option validated for automotive USB 3.0 and HDMI interfaces requiring both high-voltage tolerance and production-grade reliability.

FAQ
What is the clamping voltage specification for SZESD7102BT1G under IEC 61000-4-2 testing?
The SZESD7102BT1G does not specify a single clamping voltage for IEC 61000-4-2; instead, its clamping behavior is characterized via oscilloscope waveforms in Figures 1 and 2 of the datasheet. At ±8 kV contact discharge, the peak clamped voltage remains below 34 V for positive polarity and −5.3 V for negative polarity under TLP conditions (IPP = ±8 A), which correlate to the IEC waveform's current profile.
Is SZESD7102BT1G compatible with USB 3.0 Gen1 (5 Gb/s) data rates?
Yes, SZESD7102BT1G is explicitly validated for USB 3.0 Gen1. Its 5 GHz 3dB bandwidth, 0.3 pF capacitance, and ≤0.2 dB insertion loss at 3 GHz ensure minimal signal degradation. Figure 11 in the datasheet shows preserved eye diagrams at 5 Gb/s with and without SZESD7102BT1G installed.
Does SZESD7102BT1G support bidirectional ESD protection?
Yes, SZESD7102BT1G provides symmetric bidirectional protection. Each I/O pin (Pin 1 and Pin 3) connects to GND (Pin 2) through back-to-back diode junctions, enabling clamping of both positive and negative transients - essential for AC-coupled differential signaling like USB 3.0 and HDMI.
What is the meaning of the "SZ" prefix in SZESD7102BT1G?
The "SZ" prefix indicates automotive-grade qualification: SZESD7102BT1G is AEC-Q101 certified, manufactured under PPAP-capable processes, and subject to additional site- and control-change requirements. This distinguishes it from the commercial-grade ESD7102BT1G and confirms suitability for automotive production environments.
Can SZESD7102BT1G be used to protect MIPI D-PHY interfaces?
Yes, SZESD7102BT1G is appropriate for MIPI D-PHY v1.2/2.1 interfaces operating up to 1.5 Gbps. Its 0.3 pF capacitance, matched channel performance, and 16 V VRWM align with MIPI's 1.2 V/1.8 V/3.3 V I/O voltage ranges and provide sufficient margin against ESD-induced latch-up in mobile and automotive display bridges.
