Product details
Overview
D5V0L4B5SOQ-7 from Diodes Incorporated is a 4-channel bidirectional TVS diode array designed for ESD protection of high-speed data lines in portable electronics. It delivers ±30kV IEC 61000-4-2 contact/air ESD immunity, 5.0V reverse working voltage, 15–20pF channel capacitance, and clamps to ≤11.5V at 5A (8/20µs), making it suitable for USB 2.0, HDMI, and cellular handset data interfaces.
For engineers reviewing the D5V0L4B5SOQ-7 datasheet, D5V0L4B5SOQ-7 pinout, D5V0L4B5SOQ-7 application, or D5V0L4B5SOQ-7 equivalent, key selection criteria include low-capacitance ESD protection for multi-line signal integrity, AEC-Q101 qualification for automotive infotainment interfaces, and SOT25 package compatibility with space-constrained PCB layouts.
Technical Context
This device integrates four independent bidirectional TVS elements in a single SOT25 package, each configured as a back-to-back Zener pair between an I/O line and common ground (Pin 2). It operates with no DC bias requirement and supports transient suppression across both polarities without polarity-sensitive routing.
Its 15–20pF input capacitance at 0V and <0.2Ω differential resistance enable minimal signal distortion on 480Mbps USB 2.0 or 1.65Gbps HDMI 1.4a channels, while the 6A peak pulse current rating (8/20µs) meets IEC 61000-4-5 Level 2 surge requirements for end-equipment ports.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±30kV contact & air – ensures robust handling-level ESD immunity for handheld device interfaces |
| Reverse Working Voltage (VRWM) | 5.0V – matches standard 3.3V/5V logic rail voltages with safe margin before conduction |
| Clamping Voltage (VCL) | ≤11.5V at 5A (8/20µs) – limits transient overvoltage to protect downstream 3.3V IC inputs |
| Channel Capacitance (CT) | 15–20pF @ 0V, 1MHz – preserves signal integrity on high-speed digital lines up to 480Mbps |
| Breakdown Voltage (VBR) | 6–8V @ 1mA – defines precise turn-on threshold for controlled clamping behavior |
| Peak Pulse Power (PPP) | 84W @ 8/20µs – sustains short-duration surges without thermal runaway |
Pinout & Package
Package: SOT25 - 5-pin surface-mount plastic package with matte tin-plated copper leadframe, moisture sensitivity level 1, and UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | I/O Channel 1 | Protected signal line; connected internally to bidirectional TVS element referenced to Pin 2 |
| Pin 2 | Common Ground (GND) | Shared cathode/anode node for all four TVS channels; must be low-inductance connection to system ground |
| Pin 3 | I/O Channel 2 | Protected signal line; electrically isolated from other channels except via shared GND |
| Pin 4 | I/O Channel 3 | Protected signal line; identical electrical characteristics to Pins 1 and 3 |
| Pin 5 | I/O Channel 4 | Protected signal line; enables compact protection of quad-data buses (e.g., USB D+/D− + ID + VBUS sense) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive infotainment and telematics interfaces requiring PPAP documentation and IATF 16949 manufacturing |
| Low 15–20pF capacitance | Enables use on USB 2.0, HDMI, and MIPI D-PHY lines without signal rise-time degradation or eye-diagram closure |
| ±30kV ESD protection | Exceeds IEC 61000-4-2 Level 4, eliminating need for secondary board-level ESD components in consumer handsets |
| SOT25 footprint | Standard 5-pin package compatible with automated SMT assembly and existing reflow profiles for high-volume production |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Single-channel, 5.0V unidirectional, 600W PPP, 100pF capacitance | Requires four discrete devices and polarity-aware layout; unsuitable for high-speed data lines | Select only when protecting low-frequency power or control lines where capacitance is not critical |
| SP1003-04UTG | 4-channel, 5.0V bidirectional, ±30kV ESD, 0.5pF typical capacitance, SOT-23-6 package | Lower capacitance enables >5Gbps interfaces (e.g., USB 3.2 Gen 1), but lower 3A IPP rating | Prefer for next-gen high-speed designs; verify clamping voltage margin at full system surge current |
Compared with SMAJ5.0A and SP1003-04UTG, D5V0L4B5SOQ-7 balances moderate capacitance (15–20pF), high 6A surge capability, and AEC-Q101 qualification-making it optimal for cost-sensitive, high-volume USB 2.0 and automotive display link protection where 480Mbps fidelity and robustness are jointly required.

FAQ
What is the maximum clamping voltage of D5V0L4B5SOQ-7 at 6A surge current?
The clamping voltage is specified as ≤14.0V at 6A (8/20µs waveform), measured from any I/O pin to Pin 2 (GND). This value ensures downstream 3.3V logic circuits remain within absolute maximum ratings during worst-case surge events, provided PCB layout maintains low-inductance grounding to Pin 2.
Is D5V0L4B5SOQ-7 suitable for USB 3.0 or higher-speed interfaces?
No-its 15–20pF channel capacitance introduces excessive signal attenuation and jitter on SuperSpeed (5Gbps+) differential pairs. It is validated for USB 2.0 (480Mbps) and HDMI 1.4a (1.65Gbps) where capacitance impact remains within acceptable eye-diagram margins per specification.
How does the SOT25 package affect thermal performance during repeated ESD events?
With a junction-to-ambient thermal resistance of 417°C/W on standard FR-4 (2oz Cu), the device relies on transient energy dissipation rather than steady-state cooling. Its 84W peak pulse power rating assumes non-repetitive 8/20µs pulses; repetitive ESD events require ≥100ms spacing to avoid cumulative junction temperature rise beyond 150°C.
Does D5V0L4B5SOQ-7 require external biasing or series impedance for operation?
No-this is a passive bidirectional TVS array with no DC bias or control pins. It connects directly between protected signal lines and common ground (Pin 2). No series resistors or pull-ups are needed, though PCB trace inductance should be minimized to preserve clamping response time below 1ns.
