Product details
Overview
D2V5F4U8MR 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 2.5 V reverse standoff voltage, 2.1 pF typical channel capacitance, 80 A peak pulse current (8/20 µs), and clamps to ≤20 V at 80 A - enabling robust protection of 10/100 Ethernet PHY interfaces without signal integrity degradation.
For engineers reviewing the D2V5F4U8MR datasheet, D2V5F4U8MR pinout, D2V5F4U8MR application, or D2V5F4U8MR equivalent, key selection criteria include low-capacitance ESD immunity for multi-pair differential signaling, IEC 61000-4-2 Level 4 (±15 kV air / ±8 kV contact) compliance, and SO-8 footprint compatibility with legacy LAN transceiver layouts.
Technical Context
This device implements four independent, bidirectional TVS diodes in a single SO-8 package, each configured as a snap-back silicon avalanche structure with 2.7 V punch-through voltage and 2.5 V snap-back voltage. Its low 2.1 pF junction capacitance per channel ensures minimal loading on 100 Mbps differential pairs, while the 5 V clamping voltage at 1 A supports safe operation during low-energy ESD events.
The array meets IEC 61000-4-5 Level 3 lightning surge rating (48 A, 8/20 µs) and sustains 1000 W peak pulse power. Thermal resistance is 50.12 °C/W (junction-to-ambient, FR-4 PCB), supporting continuous operation from –55 °C to +125 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 2.5 V - Ensures no conduction during normal 3.3 V or lower logic-level signal operation. |
| Peak Pulse Current (8/20 µs) | 80 A - Withstands severe cable discharge events without failure. |
| Channel Capacitance (1 MHz) | 2.1 pF - Preserves signal rise/fall times in 10/100 Ethernet applications. |
| Clamping Voltage @ 80 A | 20 V - Limits voltage seen by protected PHY IC to non-destructive levels. |
| ESD Rating (IEC 61000-4-2) | ±15 kV air / ±8 kV contact - Meets industrial and telecom equipment immunity requirements. |
| Punch-Through Voltage | 2.7 V - Triggers fast snap-back action before sensitive interface pins exceed absolute maximum ratings. |
| Operating Temperature Range | –55 °C to +125 °C - Validated for deployment in base station and industrial edge networking gear. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ2.5A-Q | Single-channel, 2.5 V unidirectional, 100 W PPP, 25 A IPP | Requires four discrete devices; higher total capacitance (≥8 pF) degrades high-speed signal fidelity | Select only when board space permits discrete layout and speed < 10 Mbps |
| SP3205-01UTG | Quad-channel, 3.3 V VRWM, 0.6 pF CT, 12 A IPP, SOT-23-6 | Lower capacitance but insufficient for 48 A lightning surge; limited to USB/low-energy interfaces | Choose for USB 2.0 or MIPI where sub-1 pF is critical and surge threat is ESD-only |
Compared with SMAJ2.5A-Q and SP3205-01UTG, D2V5F4U8MR uniquely balances quad-channel integration, 80 A surge handling, and 2.1 pF capacitance - making it optimal for cost-sensitive, space-constrained 10/100 Ethernet designs requiring full IEC 61000-4-2/4-5 compliance.

FAQ
What is the maximum clamping voltage at 48 A for D2V5F4U8MR?
The clamping voltage is 17 V at 48 A (8/20 µs waveform), as specified in the Electrical Characteristics table on page 2 of DS43659 Rev. 3-2. This value is measured under standardized surge conditions and reflects the voltage imposed on protected circuitry during a Level 3 lightning event per IEC 61000-4-5.
Can D2V5F4U8MR be used for USB 2.0 ESD protection?
Yes - its 2.1 pF channel capacitance and ±15 kV ESD rating meet USB 2.0 signal integrity and immunity requirements. However, its 2.5 V standoff voltage requires careful matching with 3.3 V tolerant PHYs; verify that the host/device IC's absolute maximum input voltage exceeds 20 V to accommodate worst-case clamping.
Is the SO-8 package of D2V5F4U8MR compatible with standard reflow profiles?
Yes - the device is rated for peak soldering temperature of +260 °C (10 s max) and classified as Moisture Sensitivity Level 1 per J-STD-020. Standard lead-free reflow profiles (e.g., IPC/JEDEC J-STD-020 Class 3) apply without preconditioning or baking.
Does D2V5F4U8MR support AEC-Q200 qualification?
No - the datasheet explicitly states that automotive-qualified versions require specific change control, AEC-Q200 compliance, and PPAP capability, which are not included in the D2V5F4U8MR-13 orderable part. For automotive use, contact Diodes Incorporated directly to request qualified variants such as the AEC-Q200-compliant D2V5F4U8MRQ-13.
