Product details
Overview
SZESD7205DT5G from onsemi is a unidirectional ESD protection diode array designed for high-speed differential data lines including automotive Ethernet (100BASE-T1) and LVDS. It delivers 0.4 pF typical I/O-to-GND capacitance, 12 V typical clamping voltage at ±16 A TLP, and 5.0 V working peak reverse voltage in a SOT-723 package.
For engineers reviewing the SZESD7205DT5G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance matching (<10% inter-channel variation), AEC-Q101 qualification for automotive use, and flow-through layout compatibility with impedance-controlled differential pairs.
Technical Context
The SZESD7205DT5G integrates two matched unidirectional ESD protection diodes in a single SOT-723 package, configured with common-cathode topology for differential line protection. Its low 0.4 pF capacitance and tight 5–10% capacitance matching preserve signal integrity up to 5 GHz bandwidth.
It meets IEC 61000-4-2 Level 4 (±25 kV contact/air) and ISO 10605 (±30 kV, 330 pF/330 Ω), with clamping validated via TLP testing at ±8 A and ±16 A. The device operates across −55 °C to +150 °C junction temperature range and is Pb-free/RoHS compliant.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD7205WTT1G | SOT-323 package (larger, 2.0 mm × 1.25 mm); 0.47 pF typical capacitance; same electrical specs | Less suitable for space-constrained automotive camera modules due to larger footprint and non-flow-through pinout | Select when board real estate permits and legacy SOT-323 tooling is in place |
| SZESD9101MUTAG | Single-channel, 0.25 pF typical capacitance, 3.3 V VRWM, SOD-923 package | Requires two devices per differential pair; lower VRWM limits use to 3.3 V-only systems | Choose for ultra-high-frequency (>10 GHz) applications where sub-0.3 pF is mandatory |

FAQ
What is the primary function of the SZESD7205DT5G?
The SZESD7205DT5G is a dual-channel unidirectional ESD protection diode array designed to safeguard high-speed differential data lines-including 100BASE-T1, LVDS, and USB 2.0-from electrostatic discharge events. It operates by clamping transient voltages to 12 V (typical) at ±16 A TLP while adding only 0.4 pF of capacitance per channel, ensuring minimal impact on signal integrity. Its SOT-723 flow-through layout supports symmetrical PCB routing critical for impedance-controlled interfaces.
Is the SZESD7205DT5G qualified for automotive applications?
Yes, the SZESD7205DT5G is AEC-Q101 qualified and PPAP capable, with full automotive-grade reliability validation across −55 °C to +150 °C junction temperature. The "SZ" prefix explicitly denotes its suitability for automotive and other applications requiring strict process control and site-specific change management-making it appropriate for camera modules, ADAS sensors, and in-vehicle networking systems.
How does the SZESD7205DT5G differ from the ESD7205WTT1G?
The SZESD7205DT5G and ESD7205WTT1G share identical electrical specifications-including 0.4 pF vs. 0.47 pF capacitance, 12 V clamping, and 5.0 V VRWM-but differ in package: SZESD7205DT5G uses SOT-723 (1.20 mm × 0.80 mm), while ESD7205WTT1G uses larger SOT-323 (2.0 mm × 1.25 mm). Crucially, only the SOT-723 variant features flow-through pinout (Pin 1–2–3 = Anode–Cathode–Anode), enabling matched trace lengths essential for differential signaling in automotive Ethernet.
What is the meaning of "flow-through style package" for the SZESD7205DT5G?
The flow-through style of the SZESD7205DT5G's SOT-723 package means its pins are arranged linearly (Pin 1 → Pin 2 → Pin 3) with anode-cathode-anode configuration-allowing PCB traces to run straight through the device without bends or vias. This preserves differential pair symmetry, minimizes stub length, and maintains consistent characteristic impedance-critical for 100BASE-T1 and LVDS links where even minor imbalances cause return loss and jitter.
Does the SZESD7205DT5G support bidirectional signal paths?
No, the SZESD7205DT5G is a unidirectional ESD protection device, configured with two anodes (Pins 1 and 3) and one shared cathode (Pin 2) tied to ground. It protects only against positive transients on the I/O lines relative to ground. For bidirectional protection, a separate design using back-to-back diodes or a dedicated bidirectional array would be required-though the SZESD7205DT5G's low capacitance and matched performance make it ideal for unidirectional high-speed buses like 100BASE-T1 where signal directionality is fixed.
