Product details
Overview
D2V5L4U8MR from Diodes Incorporated is a dual-channel, bidirectional ESD protection diode array in SO-8 package, designed for high-speed data line protection with 2.5 V reverse standoff voltage, 2.7 V punch-through voltage, 5 pF typical junction capacitance, and 100 A peak pulse current (8/20 µs). It safeguards Ethernet PHY interfaces and integrated magnetics against ±30 kV contact/air ESD per IEC 61000-4-2 Level 4.
For engineers reviewing the D2V5L4U8MR datasheet, D2V5L4U8MR pinout, D2V5L4U8MR application, or D2V5L4U8MR equivalent, key selection criteria include low clamping voltage (11.5 V at 50 A), line-to-line vs. line-to-GND capacitance matching, dual-pair protection capability, and SO-8 thermal performance under surge conditions.
Technical Context
The D2V5L4U8MR integrates four independent TVS diodes in a single SO-8 package to protect two differential line pairs-each pair configured as back-to-back diodes between IO and GND, enabling bidirectional transient suppression. Its snap-back behavior (VSB = 2.5 V) ensures low-voltage clamping during ESD events while maintaining minimal leakage (<1 µA at 2.5 V).
It meets IEC 61000-4-5 Level 4 lightning immunity (100 A, 8/20 µs) and delivers 2400 W peak pulse power dissipation. The device operates across –55 °C to +125 °C and features halogen- and antimony-free "Green" molding compound compliant with RoHS 3 and J-STD-020 Moisture Sensitivity Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 2.5 V - Maximum continuous operating voltage before conduction begins; sets upper limit for signal swing in protected 10/100/1000 Ethernet lines. |
| Punch-Through Voltage | 2.7 V - Threshold where diode enters low-impedance state; enables fast response to sub-nanosecond ESD transients. |
| Clamping Voltage (50 A) | 11.5 V - Maximum voltage seen by downstream IC during 8/20 µs surge; ensures safe margin below typical PHY IC absolute max ratings. |
| Junction Capacitance | 5 pF - Measured line-to-GND at 0 V, 1 MHz; preserves signal integrity on 1000BASE-T differential pairs without excessive jitter. |
| Peak Pulse Current | 100 A - Withstands IEC 61000-4-5 Level 4 lightning surges; validated using standardized 8/20 µs waveform. |
| ESD Rating | ±30 kV - Complies with IEC 61000-4-2 Level 4 contact and air discharge; eliminates need for external ESD test margining. |
| Thermal Resistance θJA | 300 °C/W - Based on FR-4 PCB with 2 oz copper; defines maximum power derating above 25 °C ambient. |

| 5, 6 | IO2+, IO2− | Differential pair input/output terminals for second protected channel; electrically isolated from Channel 1 except through shared GND pins. |
| 7, 8 | GND | Redundant ground terminals to reduce package inductance and improve high-frequency surge path impedance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J24A-Q | Single-channel, unidirectional, 24 V VRWM, 600 W PPP, SMA package | Requires four discrete devices for dual-pair protection; higher capacitance (15 pF) limits use to ≤100 Mbps links | Select only when board space allows discrete layout and signal bandwidth <100 MHz. |
| SP3205-01HTG | Quad-channel, unidirectional, 3.3 V VRWM, 5.5 pF CT, SOT-23-6 | Supports only single-ended I/O; lacks line-to-line clamping mode and dual-GND thermal path | Prefer for cost-sensitive consumer USB/UART protection-not suitable for differential Ethernet or ISDN. |
Compared with SMA6J24A-Q and SP3205-01HTG, D2V5L4U8MR uniquely delivers matched dual-differential protection in one SO-8 package with sub-3 V triggering and 5 pF line-to-GND capacitance-enabling direct integration into 1000BASE-T designs without signal integrity compromise.

FAQ
What is the maximum operating temperature for D2V5L4U8MR?
The D2V5L4U8MR is rated for continuous operation from –55 °C to +125 °C junction temperature. Its thermal resistance (θJA = 300 °C/W) assumes mounting on a standard FR-4 PCB with 2 oz copper; derating is required above 25 °C ambient to maintain safe junction temperatures under sustained power dissipation.
Does D2V5L4U8MR support line-to-line ESD protection?
Yes-D2V5L4U8MR provides line-to-line clamping with a maximum clamping voltage of 24 V at 100 A (8/20 µs), verified per IEC 61000-4-2. This capability protects differential pairs against asymmetrical surges and ensures balanced voltage suppression across IO1+/IO1− and IO2+/IO2− terminals.
How does the SO-8 package affect PCB layout for high-speed signals?
The SO-8 footprint minimizes parasitic inductance with dual GND pins (pins 3,4 and 7,8) that enable low-impedance return paths. Recommended layout uses short, symmetric traces to IO pins, ground pour under the package, and avoids vias in signal paths to preserve the 5 pF capacitance specification and prevent resonance above 1 GHz.
Is D2V5L4U8MR qualified for automotive applications?
The base D2V5L4U8MR is not AEC-Q101 qualified, but Diodes offers Q-suffix automotive-grade variants (e.g., D2V5L4U8MQR) manufactured in IATF 16949-certified facilities, PPAP-capable, and tested to AEC-Q101 stress requirements for temperature cycling, HTRB, and ESD robustness.
