Product details
Overview
D5V0L4B5V-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 features 5.0 V reverse working voltage, ≤20 pF channel capacitance, ±30 kV IEC 61000-4-2 contact/air ESD rating, and SOT553 package - deployed on USB 2.0, HDMI, and cellular handset I/O interfaces.
For engineers reviewing the D5V0L4B5V-7 datasheet, D5V0L4B5V-7 pinout, D5V0L4B5V-7 application, or D5V0L4B5V-7 equivalent, key selection criteria include low-capacitance signal integrity preservation, symmetrical clamping behavior across four channels, thermal derating at elevated ambient temperatures, and compatibility with FR-4 PCB layouts per AP02001.
Technical Context
This TVS array uses silicon avalanche diode structures arranged in a common-cathode configuration per channel pair, enabling symmetrical (bidirectional) clamping without DC bias dependency. Each channel exhibits 6–8 V breakdown voltage at 1 mA and clamps to ≤9.0 V at 1 A (8/20 µs), supporting transient suppression on unpowered or floating signal paths.
Its 15–20 pF input capacitance at 0 V and 1 MHz is measured channel-to-pin 2, minimizing signal distortion on 480 Mbps USB 2.0 differential pairs. Thermal resistance is 327 °C/W on standard FR-4, limiting continuous power dissipation to 380 mW at 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 5.0 V - Maximum continuous DC or RMS signal voltage before leakage exceeds 100 nA. |
| Breakdown Voltage | 6–8 V @ 1 mA - Threshold where avalanche conduction begins; ensures robust margin above 5 V rail. |
| Clamping Voltage | ≤9.0 V @ 1 A (8/20 µs) - Peak voltage seen by protected IC during ESD event; preserves 3.3 V logic integrity. |
| Channel Capacitance | 15–20 pF @ 0 V, 1 MHz - Low enough for <1% signal rise-time degradation on USB 2.0 full-speed lines. |
| ESD Rating | ±30 kV air & contact (IEC 61000-4-2) - Meets highest industrial handheld ESD immunity requirement. |
| Peak Pulse Power | 84 W @ 8/20 µs - Sustains single high-energy transients without parametric shift or failure. |
| Thermal Resistance | 327 °C/W - Requires thermal pad or copper pour to maintain junction <150 °C at 6 A pulse repetition. |
Pinout & Package
Package: SOT553 - 5-pin, surface-mount plastic case with 0.5 mm pitch, UL 94V-0 rated molding compound, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | Common Cathode | Shared cathode node for all four channels; ties to system ground plane with low-inductance path. |
| 3 | Channel 2 Anode | Input node for second TVS path; used for complementary signal (e.g., USB D−). |
| 4 | Channel 3 Anode | Third independent ESD protection node; supports auxiliary interface like SIM card clock or reset. |
| 5 | Channel 4 Anode | Fourth anode terminal; enables protection of additional high-speed line such as audio headset mic input. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG | Lower capacitance (0.3 pF typical), but only 12 kV IEC 61000-4-2 rating; SOT-23-6 package. | Better for RF front-end protection; insufficient for handheld drop-test ESD compliance. | Select when ultra-low capacitance outweighs ESD robustness; verify layout clearance for SOT-23-6. |
| ESD5Z4.5T5G | Single-channel, 4.5 V VRWM, 12 pF, ±22 kV ESD; SOD-523 package. | Requires four separate placements; lacks integrated common-cathode architecture. | Choose only if board space allows discrete placement and cost-per-channel is prioritized over assembly yield. |
Compared with SP1006-04UTG and ESD5Z4.5T5G, D5V0L4B5V-7 uniquely balances high ESD immunity (±30 kV), moderate capacitance (15–20 pF), and 4-channel integration in SOT553 - making it optimal for compact, certified portable I/O protection where layout density and test margin are critical.

FAQ
What is the maximum clamping voltage at 6 A peak pulse current?
The D5V0L4B5V-7 clamps to ≤14.0 V at 6 A (8/20 µs pulse), per Electrical Characteristics table on page 2 of DS35568 Rev. 6-2. This value ensures downstream 5 V tolerant I/O cells remain within safe operating limits during worst-case ESD strikes, provided the common cathode is routed to a low-impedance ground plane.
Can this device protect differential USB 2.0 signals without skew or imbalance?
Yes - its matched channel capacitance (15–20 pF) and symmetrical bidirectional structure ensure <0.05 dB amplitude imbalance and <0.1 ps skew between D+ and D− paths at 480 MHz. Layout symmetry and equal trace lengths are required to preserve this performance in practice.
Is the SOT553 package compatible with standard reflow profiles?
Yes - the SOT553 package meets JEDEC J-STD-020 moisture sensitivity level 1 and is qualified for IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C for ≤30 seconds. No pre-bake is required prior to assembly.
Does the common cathode (Pin 2) require a dedicated thermal pad?
No dedicated thermal pad is mandatory, but Diodes recommends using ≥25 mm² of 2 oz copper connected directly to Pin 2 for sustained pulse handling. Without it, thermal resistance rises above 327 °C/W, risking junction exceedance during repetitive 6 A pulses at >25 °C ambient.
