Product details
Overview
D8V0L1B2LP-7B from Diodes Incorporated is a bidirectional transient voltage suppression (TVS) diode designed for ESD protection of high-speed data lines in portable electronics. It features a 8.5V minimum breakdown voltage, ±25kV IEC 61000-4-2 contact/air ESD rating, 8.5pF typical channel capacitance, 4A peak pulse current, and X1-DFN1006-2 (1.08 × 0.68 mm) package - enabling robust protection in space-constrained interfaces like USB 2.0 and audio jacks.
For engineers reviewing the D8V0L1B2LP-7B datasheet, D8V0L1B2LP-7B pinout, D8V0L1B2LP-7B application, or D8V0L1B2LP-7B equivalent, key selection criteria include low clamping voltage (13.0V @ 1A), ultra-low capacitance for signal integrity, RoHS/Green compliance, thermal derating behavior, and compatibility with automated SMT assembly on FR-4 PCBs.
Technical Context
This TVS diode operates as a voltage-clamped shunt device triggered by electrostatic discharge events exceeding its 8.5V breakdown threshold. Its bidirectional architecture protects both positive and negative transients without polarity dependency, and its 8.5pF junction capacitance ensures minimal distortion on 480 Mbps USB 2.0 signals.
The device uses silicon avalanche technology with NiPdAu-plated copper terminals and is rated for -65°C to +150°C operation. Its 500°C/W junction-to-ambient thermal resistance requires careful PCB pad layout per Diodes' recommended footprint to sustain 250 mW continuous power dissipation at 25°C ambient.
Key Specifications

|---|---|
| Breakdown Voltage (VBR) | 8.5 V min - Ensures reliable triggering before damage to downstream 3.3V or 5V logic circuits |
| Clamping Voltage (VCL) | 13.0 V @ 1A - Limits voltage seen by protected IC during ESD event to safe level |
| Peak Pulse Current (IPP) | 4 A @ 8/20µs - Withstands industrial-grade surge stress without degradation |
| Channel Capacitance (CT) | 8.5 pF @ 0V, 1MHz - Preserves signal rise/fall times in high-speed digital interfaces |
| ESD Rating | ±25 kV air & contact - Meets highest IEC 61000-4-2 Level 4 immunity requirement |
| Package | X1-DFN1006-2 - 1.08 × 0.68 mm footprint fits tight spacing around connectors and ports |
Pinout & Package
Package: X1-DFN1006-2 - ultra-compact, leadless, surface-mount plastic package with two terminals, 0.53 mm max height, and NiPdAu over copper terminals for reliable solderability.

Applications
| USB 2.0 Interface Protection | Smartphone Audio Jack ESD Guard |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports against repeated ESD events during cable insertion/removal. IC Role / Device Role: Bidirectional shunt TVS placed directly at connector entry point to divert ESD energy to ground before reaching PHY IC. Use Value: 8.5pF capacitance avoids signal integrity loss; 13.0V clamping prevents latch-up in USB transceivers operating at 3.3V. | Use Scenario: Safeguarding 3.5mm TRRS audio jack pins (mic, left/right, ground) in smartphones exposed to user-hand ESD. IC Role / Device Role: Single-channel TVS deployed per signal line to suppress ±25kV contact discharges without degrading analog audio bandwidth. Use Value: Low leakage (<100nA) prevents DC offset in microphone bias networks; 0.53mm profile fits under mechanical shield. |
| Portable Display Data Lines | SD Card Interface Protection |
Use Scenario: Shielding MIPI D-PHY clock and data lanes between application processor and OLED display module. IC Role / Device Role: Low-capacitance TVS placed adjacent to display connector to clamp fast-rising ESD pulses without distorting 1.5 Gbps differential signals. Use Value: 8.5pF ensures <10 ps jitter contribution; 4A IPP handles multiple ESD strikes across product lifetime. | Use Scenario: Securing SDIO command, clock, and data lines in tablets and action cameras subjected to frequent card swaps. IC Role / Device Role: Channel-specific TVS on each SD bus line to prevent ESD-induced corruption of FAT32 file system writes. Use Value: 8.5V VBR avoids false triggering during 3.3V SD bus signaling; RoHS/Green compliance meets OEM environmental mandates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | DO-214AC package (4.5 × 2.7 mm), 100pF CT, 12.5V VBR, 30A IPP | Designed for board-level surge (IEC 61000-4-5), not high-speed signal lines | Select when protecting power rails or low-frequency I/O where capacitance is non-critical |
| TPD2E001DRYR | 2-channel, 12pF CT, 5.5V VBR, ±8kV ESD rating, same X2-SON package | Lower ESD rating and higher capacitance; optimized for HDMI/DisplayPort, not USB 2.0 | Choose only if dual-line protection and lower clamping voltage outweigh reduced ESD margin |
Compared with SMAJ8.0A and TPD2E001DRYR, D8V0L1B2LP-7B uniquely balances sub-10pF capacitance, ±25kV ESD immunity, and 1.08 mm² footprint - making it optimal for miniaturized USB 2.0, audio, and MIPI interface protection where signal fidelity and space are constrained.

FAQ
What is the maximum operating temperature for D8V0L1B2LP-7B?
The device operates from -65°C to +150°C, with thermal derating beginning above 25°C ambient. At 85°C ambient, its peak pulse power drops to ~125 mW per the Figure 1 derating curve, requiring appropriate PCB copper area to maintain reliability under sustained surge conditions.
Can D8V0L1B2LP-7B protect USB 3.0 or HDMI interfaces?
No - its 8.5pF capacitance exceeds the <1.5pF typical requirement for USB 3.0 SuperSpeed (5 Gbps) and HDMI 2.0 (6 Gbps) channels. It is validated for USB 2.0 (480 Mbps), audio, SDIO, and MIPI D-PHY up to 1.5 Gbps where higher capacitance is tolerable.
Is D8V0L1B2LP-7B compatible with lead-free reflow profiles?
Yes - it is fully RoHS-compliant and qualified for standard Pb-free reflow per J-STD-020. The NiPdAu terminal plating ensures wetting and joint integrity at peak temperatures up to 260°C, matching common Class 3 assembly processes.
How does the clamping voltage change with different surge currents?
VCL rises from 13.0V at 1A to 17.0V at 4A (8/20µs waveform). This predictable, monotonic increase allows accurate worst-case voltage margining in protected circuit design - e.g., ensuring 17.0V remains below the absolute maximum rating of downstream 18V-tolerant I/O cells.
