Product details
Overview
D5V0L2B3SO-7 from Diodes Incorporated is a 2-channel, bidirectional TVS diode array in SOT23 package, rated for 5.0 V reverse working voltage, ±30 kV IEC 61000-4-2 ESD protection (contact/air), and 15–20 pF channel input capacitance. It protects high-speed data lines in portable electronics against transient overvoltages.
For engineers reviewing the D5V0L2B3SO-7 datasheet, D5V0L2B3SO-7 pinout, D5V0L2B3SO-7 application, or D5V0L2B3SO-7 equivalent, key selection criteria include low-capacitance ESD clamping for USB 2.0, HDMI, or audio interface protection with symmetrical bidirectional response and SOT23 footprint compatibility.
Technical Context
This TVS array employs two independent, symmetrical bidirectional avalanche junctions sharing a common cathode (Pin 3), enabling dual-line protection without polarity constraints. Each channel delivers 6 A peak pulse current handling (8/20 µs) with clamping voltage ≤9.0 V at 1 A and ≤14.0 V at 6 A.
Designed for signal integrity preservation, it maintains ≤20 pF total capacitance per channel at 0 V bias and 1 MHz, with differential resistance of 0.2 Ω under 1 A transient stress-critical for preserving edge rates in high-speed digital interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 5.0 V - Maximum continuous DC or RMS signal voltage before leakage rises significantly. |
| Breakdown Voltage | 6–8 V at 1 mA - Ensures reliable triggering above normal operating voltage but below IC damage thresholds. |
| Clamping Voltage | ≤9.0 V at 1 A - Limits transient voltage seen by protected IC to safe levels during ESD events. |
| Channel Capacitance | 15–20 pF at 0 V, 1 MHz - Low enough to avoid signal distortion on USB 2.0 or audio lines. |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - Meets highest industrial ESD immunity requirements. |
| Peak Pulse Power | 84 W (8/20 µs) - Sustains high-energy transients without failure in handheld device drop scenarios. |
Pinout & Package
Package: SOT23 (3-pin, surface-mount), JEDEC TO-236AB compliant; dimensions 2.9 × 1.3 × 1.0 mm (L × W × H); moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Channel 1 Anode/Cathode Junction | Bidirectional ESD path for first protected line; connects to I/O trace needing clamping. |
| Pin 2 | Channel 2 Anode/Cathode Junction | Bidirectional ESD path for second protected line; electrically isolated from Pin 1. |
| Pin 3 | Common Cathode Terminal | Shared reference node; must be connected to system ground plane for effective clamping. |

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 | Unidirectional, higher capacitance (≈40 pF), DO-214AC package | Requires separate devices per line; unsuitable for AC-coupled or differential signals | Choose only when polarity is fixed and board area allows larger package. |
| TPD2E001DRSR | 2-channel, bidirectional, 10 pF typical, 0.65 mm pitch DFN | Smaller footprint (1.0 × 0.6 mm), but requires tighter assembly control and lacks SOT23 compatibility | Select when ultra-low capacitance and miniaturization outweigh reworkability and legacy footprint needs. |
Compared with SMAJ5.0A and TPD2E001DRSR, D5V0L2B3SO-7 uniquely balances SOT23 manufacturability, symmetrical bidirectional response, and 15–20 pF capacitance-making it optimal for cost-sensitive, high-volume portable designs where layout flexibility and proven process yield matter.

FAQ
What is the maximum clamping voltage at 6 A peak pulse current?
The D5V0L2B3SO-7 clamps to ≤14.0 V at 6 A (8/20 µs waveform), measured channel-to-common cathode (Pin 3). This value ensures downstream logic-level ICs remain within absolute maximum ratings during worst-case surge events, verified per IEC 61000-4-5 Annex C test conditions.
Can this device protect differential signal pairs like USB D+/D− without skew?
Yes-its matched channel capacitance (15–20 pF) and symmetrical bidirectional structure ensure <0.5 ps inter-channel skew under ESD stress. The shared cathode (Pin 3) eliminates ground loop differences, preserving differential timing integrity essential for USB 2.0 compliance.
Is the SOT23 package lead-free and RoHS 2 compliant?
Yes-D5V0L2B3SO-7 uses matte tin plating over Alloy 42 leadframe, fully compliant with EU Directive 2011/65/EU (RoHS 2). It contains no intentionally added lead, halogens, or antimony, and meets UL 94V-0 flammability rating per molded compound specification.
How does thermal resistance affect derating at elevated ambient temperatures?
With RθJA = 417 °C/W on standard FR-4 (2 oz copper), power dissipation must be linearly derated above 25 °C ambient. At 85 °C, maximum allowable continuous power drops to ~175 mW-well within its 300 mW rating at 25 °C, ensuring safe operation in sealed handheld enclosures.
