Product details
Overview
D2V8F4U8MR from Diodes Incorporated is a quad-channel ESD protection diode array in SO-8 package, designed for bidirectional transient suppression on high-speed data lines. It delivers 2.8 V reverse standoff voltage, 3.0 V punch-through voltage, 2.6 pF typical channel capacitance, ±8 kV contact/±15 kV air ESD rating per IEC 61000-4-2, and clamps to ≤5 V at 1 A for Ethernet PHY interface protection.
For engineers reviewing the D2V8F4U8MR datasheet, D2V8F4U8MR pinout, D2V8F4U8MR application, or D2V8F4U8MR equivalent, key selection criteria include low-capacitance line protection (≤3 pF), dual-pair (four-line) layout compatibility, IEC 61000-4-5 Level 2 lightning surge capability (24 A, 8/20 µs), and SO-8 footprint suitability for 10/100/1000BASE-T routing density constraints.
Technical Context
This device implements four independent, back-to-back silicon avalanche diode pairs in a single SO-8 package, enabling simultaneous protection of two differential pairs (e.g., TX+/TX− and RX+/RX−). Each channel features low dynamic capacitance (2.6 pF @ 0 V, 1 MHz) and snap-back behavior with 2.8 V snap-back voltage at 50 mA.
It operates within −55 °C to +125 °C junction temperature range, supports 80 A peak pulse current (8/20 µs), and achieves 600 W peak pulse power dissipation under standardized surge conditions. Thermal resistance is 54.26 °C/W (junction-to-ambient, FR-4 board).
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG | Higher 3.5 pF capacitance; 3.3 V standoff; ±12 kV air ESD rating | Better suited for lower-speed USB 2.0 or RS-485 where capacitance margin is relaxed | Select when cost sensitivity outweighs 1000BASE-T signal integrity requirements |
| SZ1.8SMF28A-TP | Single-channel, 28 V standoff; 100 W PPP; no multi-line integration | Requires four discrete devices and additional PCB area; lacks differential pair optimization | Choose only if SO-8 footprint is unavailable or legacy design reuse mandates discrete placement |
Compared with SP1006-04UTG and SZ1.8SMF28A-TP, D2V8F4U8MR provides superior high-speed interface compatibility via its 2.6 pF capacitance and integrated dual-pair layout, reduces BOM count by 75% versus discrete solutions, and delivers tighter clamping (≤5 V @ 1 A) critical for 2.5 V PHY rail margins.

FAQ
What is the maximum operating temperature for D2V8F4U8MR?
The D2V8F4U8MR has a specified operating junction temperature range of −55 °C to +125 °C. Its thermal resistance (RθJA) is 54.26 °C/W when mounted on a standard FR-4 PCB with Diodes' recommended pad layout. Derating is required above 25 °C ambient to maintain safe junction temperatures under 80 A pulse conditions.
Does D2V8F4U8MR require external bias or control signals?
No. D2V8F4U8MR is a passive, bidirectional ESD protection array with no external bias, enable pins, or control logic. It operates solely through avalanche breakdown and snap-back conduction, making it compatible with unpowered or hot-plug scenarios common in Ethernet and telecom interfaces.
Can D2V8F4U8MR be used for USB 3.0 SuperSpeed differential pairs?
No. While its 2.6 pF capacitance meets USB 2.0 requirements, USB 3.0 SuperSpeed (5 Gbps) demands ≤0.3 pF per line to avoid excessive insertion loss and return loss degradation. D2V8F4U8MR's capacitance is too high for Gen 1/Gen 2 compliance and may cause eye closure beyond 1 GHz.
Is D2V8F4U8MR qualified for automotive applications?
No. D2V8F4U8MR is not AEC-Q200 qualified. Diodes offers automotive-grade equivalents (e.g., D2V8F4U8MQ) with Q-suffix marking, PPAP documentation, and IATF 16949 manufacturing certification. This part is intended for commercial/industrial use only.
