Product details
Overview
DBLC08CI-7 from Diodes Incorporated is a bidirectional ultra-low-capacitance TVS diode designed for ESD protection of high-speed data lines, featuring 8.5V reverse breakdown voltage, 14A peak pulse current (8/20μs), 0.6pF typical input capacitance, and ±27kV contact / ±30kV air ESD immunity per IEC 61000-4-2 - deployed in USB 2.0 and 10/100/1000BASE-T Ethernet interfaces.
For engineers reviewing the DBLC08CI-7 datasheet, DBLC08CI-7 pinout, DBLC08CI-7 application, or DBLC08CI-7 equivalent, this device is selected for signal integrity-critical ESD protection where sub-1pF capacitance, low clamping voltage (13.4V at 1A), and SOD323 footprint compatibility are mandatory design constraints.
Technical Context
The DBLC08CI-7 implements a single-channel, symmetric (bidirectional) avalanche-clamping structure optimized for transient suppression on unidirectional or differential data paths. Its 8.5V VBR ensures reliable conduction before system-level IC damage thresholds, while 13.4V VCL at 1A limits voltage overshoot during fast ESD events.
Thermal design is constrained by 500°C/W junction-to-ambient resistance and 250mW steady-state power dissipation on FR-4 PCBs. The device operates across –55°C to +150°C, supporting industrial and automotive-adjacent environments without derating up to 125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR Min | 8.5V - Ensures clamping activation before damage to 3.3V/5V interface ICs |
| IPP Max | 14A (8/20μs) - Withstands worst-case IEC 61000-4-2 contact discharge pulses |
| CIN Typ | 0.6pF @ 0V, 1MHz - Preserves signal integrity on USB 2.0 (480Mbps) and Gigabit Ethernet lanes |
| VCL @ 1A | 13.4V - Limits transient overvoltage to safe margin below 15V rail-tolerant receivers |
| ESD Rating | ±27kV contact / ±30kV air - Meets highest IEC 61000-4-2 Level 4 immunity requirement |
| PPP | 350W (8/20μs) - Sustains multi-pulse ESD stress without parametric shift |
Pinout & Package

Applications
| USB 2.0 Interface Protection | Ethernet PHY Line Protection |
|---|---|
Use Scenario: Protecting D+ and D– lines of USB 2.0 host/device ports against user-handling ESD events. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point. Use Value: 0.6pF capacitance avoids signal rise-time degradation; 13.4V clamping prevents damage to USB transceivers rated ≤15V absolute maximum. | Use Scenario: Shielding 10/100/1000BASE-T twisted-pair differential pairs (e.g., TX+/TX–, RX+/RX–) from cable-discharge events. IC Role / Device Role / Timing Role: Per-lane ESD clamp mounted adjacent to RJ45 magnetics or PHY package. Use Value: Symmetric breakdown enables identical protection on both polarity phases; low CIN preserves 100MHz bandwidth required for Gigabit signaling. |
| Handheld Wireless Antenna Feedline | Industrial Sensor Interface |
Use Scenario: Guarding RF front-end antenna switch control lines or low-frequency GPIOs in cellular/Wi-Fi modules. IC Role / Device Role / Timing Role: Low-leakage (2μA @ 8V) ESD shunt on DC-biased control traces near antenna aperture. Use Value: Sub-1pF capacitance avoids detuning of matching networks; ±27kV rating withstands repeated pocket-contact discharges. | Use Scenario: Securing analog/digital I/O lines (e.g., RS-485, CAN FD, or ADC inputs) in factory-floor sensors exposed to operator touch. IC Role / Device Role / Timing Role: Primary ESD barrier between field wiring and ASIC/MCU pins operating at 3.3V or 5V. Use Value: 8.5V VBR provides 0.5V guard band above 8V common-mode noise; –55°C to +150°C operation supports extended temperature deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | Higher capacitance (15pF), higher VBR (8.0V min), larger SMA package | Not suitable for >100Mbps data lines due to capacitance; better for power-rail or low-speed GPIO | Select only when board space allows SMA and signal bandwidth <10MHz |
| TPD2E001DRYR | 0.9pF CIN, dual-channel, same SOD-323 footprint, lower IPP (4A) | Designed for USB D+/D– pair protection in single package; lower surge rating limits robustness | Prefer for cost-sensitive dual-line designs where 4A IPP suffices |
Compared with SMAJ8.0A and TPD2E001DRYR, the DBLC08CI-7 uniquely balances sub-1pF capacitance, 14A surge capability, and SOD323 size - making it optimal for high-speed, space-constrained ESD protection where both bandwidth and ruggedness are required.

FAQ
What is the maximum operating temperature range for DBLC08CI-7?
The DBLC08CI-7 is rated for junction temperatures from –55°C to +150°C, with no derating required up to +125°C ambient on standard FR-4 PCBs. This range supports deployment in industrial control panels, automotive infotainment head units, and outdoor wireless infrastructure where thermal extremes occur.
Does DBLC08CI-7 require external biasing or control signals?
No. The DBLC08CI-7 is a passive, two-terminal device with no bias, enable, or configuration pins. It operates solely via avalanche breakdown under transient overvoltage conditions and draws zero quiescent current during normal operation at VRWM ≤ 8V.
Can DBLC08CI-7 be used for DC power rail protection?
No. Its 8.5V VBR and 13.4V clamping voltage make it unsuitable for 12V or 24V power rails. It is engineered exclusively for signal-line protection - specifically high-speed data interfaces where capacitance must remain below 1pF to avoid signal distortion.
How does the 0.6pF input capacitance impact USB 2.0 signal integrity?
At 0.6pF, the DBLC08CI-7 introduces negligible loading on USB 2.0 differential pairs: insertion loss remains <0.2dB and eye diagram jitter increase is <1% at 480Mbps. This meets USB-IF compliance requirements for connector-side ESD components without requiring equalization or layout compensation.
