Product details
Overview
D5V0L4B5SO-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, ±30 kV IEC 61000-4-2 contact/air ESD rating, 15–20 pF channel capacitance, and SOT25 package-used in USB 2.0, HDMI, and cellular handset interface protection.
For engineers reviewing the D5V0L4B5SO-7 datasheet, D5V0L4B5SO-7 pinout, D5V0L4B5SO-7 application, or D5V0L4B5SO-7 equivalent, key selection criteria include low-capacitance ESD clamping for signal integrity, bidirectional symmetry for AC-coupled lines, thermal derating at elevated ambient temperatures, and compatibility with FR-4 PCB layouts per AP02001.
Technical Context
This TVS array integrates four independent bidirectional avalanche diodes in a single SOT25 package, each configured as a symmetrical back-to-back PN junction pair to clamp transient overvoltage in both polarities. Its low 15–20 pF input capacitance minimizes signal distortion on high-frequency interfaces up to 500 MHz.
The device operates within –65°C to +150°C junction temperature range and delivers 84 W peak pulse power (8/20 μs) per channel. Clamping voltage remains ≤9.0 V at 1 A IPP and ≤14.0 V at 6 A IPP, enabling robust protection without compromising downstream IC input thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 5.0 V - Sets maximum continuous DC or RMS signal voltage before leakage increases significantly. |
| Breakdown Voltage | 6–8 V @ 1 mA - Defines onset of avalanche conduction; ensures reliable triggering before system damage. |
| Clamping Voltage | ≤9.0 V @ 1 A - Limits transient voltage seen by protected IC inputs during ESD events. |
| Channel Capacitance | 15–20 pF @ 0 V, 1 MHz - Enables use on USB 2.0 (480 Mbps) and other high-speed digital lines. |
| ESD Rating | ±30 kV air/contact per IEC 61000-4-2 - Meets highest industrial ESD immunity requirements. |
| Peak Pulse Power | 84 W per channel (8/20 μs) - Supports multi-event surge handling without thermal runaway. |
| Thermal Resistance | 417 °C/W (Junction-to-Ambient) - Requires minimal copper area for safe operation at full rated power. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional low-capacitance TVS array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Single-channel, unidirectional, 500 W PPP, 65 pF capacitance | Requires four discrete devices; unsuitable for high-speed differential lines due to high capacitance | Select only when protecting low-frequency DC signals where capacitance is non-critical |
| SP1003-04UTG | 4-channel, bidirectional, 5.5 V VRWM, 0.3 pF typical capacitance, SOT-23-6 | Lower capacitance enables >5 Gbps interfaces but higher cost and different pinout | Prefer for USB 3.0 or PCIe Gen1 if budget allows and layout supports SOT-23-6 footprint |
Compared with SMAJ5.0A and SP1003-04UTG, D5V0L4B5SO-7 offers optimal balance of cost, 4-channel integration, and 15–20 pF capacitance for USB 2.0/HDMI 1.3-making it ideal for mid-bandwidth consumer interfaces where board space and BOM count are constrained.

FAQ
What is the maximum clamping voltage of D5V0L4B5SO-7 at 6 A peak pulse current?
The clamping voltage is guaranteed ≤14.0 V under 8/20 μs waveform at 6 A peak pulse current, measured channel-to-common cathode (Pin 2). This value ensures protected ICs with 13.5 V absolute maximum ratings remain within safe operating limits during worst-case ESD events.
Can D5V0L4B5SO-7 be used on 3.3 V logic lines?
Yes-its 5.0 V reverse working voltage provides sufficient margin above 3.3 V nominal rails, with leakage <100 nA at VRWM. The 6–8 V breakdown ensures no conduction during normal operation while still triggering reliably during ESD transients exceeding 8 V.
Is the SOT25 package compatible with standard reflow profiles?
Yes-D5V0L4B5SO-7 meets J-STD-020 Level 1 moisture sensitivity and is qualified for Pb-free reflow per IPC/JEDEC J-STD-020. Peak temperature must not exceed 260°C, with time above 217°C limited to 40–120 seconds using standard SnAgCu profile.
How does the common cathode configuration affect circuit layout?
The shared cathode (Pin 2) requires a low-inductance, wide copper pour connection directly to system ground-ideally via multiple vias-to minimize clamping impedance. Routing protected signal traces directly to Pins 1/3/4/5 without stubs ensures optimal high-frequency ESD suppression performance.
