Product details
Overview
D5V0L1B2T-7 from Diodes Incorporated is a low-capacitance bidirectional TVS diode designed for ESD protection of high-speed data lines in portable electronics. It delivers ±30 kV IEC 61000-4-2 contact/air discharge immunity, features 5 V reverse standoff voltage, 15–20 pF input capacitance at 0 V, 6 A peak pulse current (8/20 µs), and clamps transients to ≤14.0 V at 6 A - enabling robust protection for USB 2.0, HDMI, and audio jack interfaces.
For engineers reviewing the D5V0L1B2T-7 datasheet, D5V0L1B2T-7 pinout, D5V0L1B2T-7 application, or D5V0L1B2T-7 equivalent, key selection criteria include low-channel capacitance (<20 pF), symmetrical bidirectional clamping, SOD523 footprint compatibility, and validated ±30 kV ESD performance in space-constrained consumer interface designs.
Technical Context
This TVS diode operates as a voltage-clamped transient suppressor across a single bidirectional signal path. Its symmetrical breakdown (6–8 V @ 1 mA) and low differential resistance (≤0.2 Ω) ensure balanced clamping for both positive and negative transients without polarity biasing requirements.
The device leverages silicon avalanche structure with optimized junction design to achieve sub-20 pF capacitance while sustaining 84 W peak pulse power (8/20 µs). Thermal resistance of 454 °C/W (FR-4, 2 oz Cu) supports reliable operation up to +150 °C ambient in compact handheld PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous working voltage before leakage exceeds 100 nA; sets upper limit for protected line DC bias. |
| Breakdown Voltage | 6–8 V @ 1 mA - Confirmed avalanche onset range; ensures reliable triggering before downstream IC damage thresholds. |
| Clamping Voltage | ≤14.0 V @ 6 A - Peak voltage seen by protected circuit during worst-case 8/20 µs surge; stays below typical 15 V I/O absolute max ratings. |
| Channel Input Capacitance | 15–20 pF @ 0 V, 1 MHz - Low enough to avoid signal integrity degradation on 480 Mbps USB 2.0 or 1080p HDMI TMDS lines. |
| ESD Protection Level | ±30 kV air & contact - Meets highest IEC 61000-4-2 severity level; eliminates need for secondary ESD stages in end-product validation. |
| Peak Pulse Power | 84 W (8/20 µs) - Sustains multi-event surge stress in handheld drop-test and cable-charge scenarios without parametric shift. |
Pinout & Package
Package: SOD523 - ultra-compact surface-mount package (1.6 × 0.8 × 0.6 mm) with matte tin-plated alloy 42 leadframe; moisture sensitivity level 1; UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (Bidirectional) | Common transient path | Both terminals function identically; no polarity marking required - simplifies layout and eliminates orientation errors during placement. |
| Case (Exposed Pad) | Non-electrical thermal path | No internal connection; serves only mechanical anchoring and heat dissipation via PCB copper; not a ground node. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD suppression | Enables single-device protection of AC-coupled or differential lines (e.g., USB D+/D−) without external biasing networks. |
| 15–20 pF channel capacitance | Preserves rise time and eye diagram integrity on 480 Mbps USB 2.0 signals; avoids added jitter or attenuation in audio codecs. |
| ±30 kV IEC 61000-4-2 rating | Passes full-system ESD qualification per EN 61000-4-2 Level 4 without redesign; reduces test failure risk in production. |
| SOD523 footprint | Matches industry-standard 0201-size land pattern; allows direct replacement of legacy TVS devices without PCB rework. |
Applications
| USB 2.0 Interface Protection | HDMI Hot-Plug Detection Line |
|---|---|
Use Scenario: Protecting D+ and D− lines in smartphone USB OTG ports against user-handling ESD events during cable insertion. IC Role / Device Role: Bidirectional transient voltage suppressor placed directly at connector, shunting ESD energy to ground before reaching USB PHY. Use Value: 15–20 pF capacitance prevents signal distortion at 480 Mbps; ±30 kV rating ensures zero field failures in >1M unit deployments. | Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) pin against electrostatic discharge when plugging/unplugging display cables. IC Role / Device Role: Low-leakage (≤100 nA) TVS clamp that remains transparent during 5 V DC HPD signaling but triggers within nanoseconds on ESD spikes. Use Value: 5 V standoff voltage aligns precisely with HDMI HPD logic threshold; avoids false disconnect detection during normal operation. |
| Smartphone Audio Jack ESD | Industrial Sensor Interface |
Use Scenario: Shielding 3.5 mm TRRS audio jack contacts (MIC, L/R, GND) from user-touch ESD in mobile handsets. IC Role / Device Role: Single-channel bidirectional protector applied per signal line; leverages symmetry to handle mixed-polarity transients from headphone plug insertion. Use Value: SOD523 size fits tight jack-side routing; sub-20 pF capacitance prevents audible pop/click artifacts during MIC biasing. | Use Scenario: Protecting RS-485 transceiver I/O pins in factory-floor PLC modules exposed to maintenance personnel ESD. IC Role / Device Role: Front-end transient suppressor mounted adjacent to connector, limiting voltage excursion to <14 V during 6 A surges. Use Value: 84 W peak power rating withstands repeated industrial ESD events; -65°C to +150°C operating range supports extended temperature deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Unidirectional; higher capacitance (≈60 pF); DO-214AC package (3.5 × 2.7 mm) | Requires separate devices per polarity; unsuitable for AC-coupled lines like USB | Select only if board space permits larger package and unidirectional biasing is acceptable. |
| TPD2E001DRYR | 2-channel array; 12 pF typical; 0.65 mm pitch DRY (X2SON-6) package | Protects two lines simultaneously; requires precise layout for crosstalk control | Prefer for dual-line interfaces (e.g., HDMI DDC) where density and matched capacitance matter. |
Compared with SMAJ5.0A and TPD2E001DRYR, D5V0L1B2T-7 uniquely combines bidirectional operation, sub-20 pF capacitance, and SOD523 size - making it optimal for single-line, space-constrained, high-speed port protection where polarity-agnostic clamping is mandatory.

FAQ
What is the maximum clamping voltage of D5V0L1B2T-7 under a 6 A transient?
The maximum clamping voltage is 14.0 V at 6 A peak pulse current (8/20 µs waveform), as specified in the Electrical Characteristics table. This value is measured with the device mounted on a standard FR-4 PCB per Diodes' AP02001 pad layout, ensuring realistic system-level performance validation.
Does D5V0L1B2T-7 require polarity-specific PCB layout?
No - D5V0L1B2T-7 is a symmetrical bidirectional TVS diode with identical anode/cathode characteristics. Its SOD523 package has no polarity marking, and the device functions identically regardless of orientation, eliminating assembly errors and simplifying layout for differential or AC-coupled signal paths.
Can D5V0L1B2T-7 be used on 3.3 V logic lines?
Yes - its 5 V reverse standoff voltage provides sufficient margin above 3.3 V nominal rails, with leakage current limited to ≤100 nA at VRWM. The 6–8 V breakdown ensures reliable triggering before damaging 3.3 V I/O structures, and clamping remains below 14 V even at 6 A surge.
Is the SOD523 package compatible with standard 0201 pick-and-place equipment?
Yes - the SOD523 (1.6 × 0.8 mm) footprint matches IPC-7351B 0201 land pattern standards. Diodes specifies matte tin finish and J-STD-020 Level 1 moisture sensitivity, enabling compatibility with standard reflow profiles and automated assembly processes without special handling requirements.
