Product details
Overview
D8V0X1B2LP-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 reverse working voltage of 8.0 V, ultra-low junction capacitance of 0.5 pF at 1 MHz, ±24 kV air/±20 kV contact ESD immunity per IEC 61000-4-2, and a compact X1-DFN1006-2 package (1.08 mm × 0.68 mm). It is deployed on USB 2.0, HDMI, and audio interface traces in smartphones and digital cameras.
For engineers reviewing the D8V0X1B2LP-7B datasheet, D8V0X1B2LP-7B pinout, D8V0X1B2LP-7B application, or D8V0X1B2LP-7B equivalent, key selection criteria include clamping voltage under 4 A surge (18.5 V), dynamic resistance of 0.6 Ω, thermal resistance of 500 °C/W, and compliance with RoHS 3, halogen-free, and AEC-Q200-ready manufacturing processes.
Technical Context
This TVS diode operates as a bidirectional clamp between two signal lines (Pin 1 ↔ Pin 2), activating only during overvoltage transients exceeding its 9.5 V minimum breakdown voltage. Its low 0.5 pF capacitance ensures minimal signal integrity degradation on high-frequency interfaces up to 1 GHz.
The device uses silicon avalanche structure with NiPdAu-plated copper leadframe terminals, rated for 250 mW power dissipation on standard FR-4 PCBs and capable of withstanding 8/20 µs lightning surges per IEC 61000-4-5 up to 4 A peak pulse current.
Key Specifications

| VRWM | 8.0 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets upper limit for signal swing in protected line. |
| VBR (Min) | 9.5 V - Minimum breakdown voltage at 1 mA; defines earliest activation threshold for ESD clamping. |
| VCL @ 4 A | 18.5 V - Clamping voltage during full-rated 4 A 8/20 µs surge; determines maximum voltage seen by downstream IC. |

| ESD Rating | ±24 kV air / ±20 kV contact - Full IEC 61000-4-2 Level 4 compliance; meets end-equipment certification requirements for handheld devices. |
| PD | 250 mW - Steady-state power dissipation on standard 2 oz copper FR-4 pad; defines thermal derating envelope above 25°C ambient. |
| RθJA | 500 °C/W - Junction-to-ambient thermal resistance; used to calculate temperature rise under sustained leakage or repeated surges. |

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 | Unidirectional, DO-214AC package (4.5 mm × 3.9 mm), CT = 250 pF, VBR = 8.9 V min, VCL = 12.8 V @ 12.3 A | Requires polarity-aware layout; unsuitable for differential or AC-coupled signals; used in power rail protection, not high-speed data | Select only for DC-biased supply line protection where size and capacitance are non-critical. |
| SP1001-01UTG | Bidirectional, SOD-523 package (1.3 mm × 0.85 mm), CT = 0.3 pF, VBR = 10.5 V min, VCL = 20 V @ 4 A, IEC 61000-4-2 ±30 kV air | Higher clamping voltage and tighter capacitance tolerance; preferred for >1 Gbps interfaces like MIPI D-PHY | Choose when designing for next-gen camera modules requiring >±30 kV ESD margin and sub-0.35 pF loading. |
Compared with SMAJ8.0A and SP1001-01UTG, D8V0X1B2LP-7B delivers optimal balance of ultra-low capacitance (0.5 pF), industry-standard ±20/24 kV ESD rating, and minimal footprint-making it the preferred choice for cost-sensitive, space-constrained USB 2.0 and audio applications where clamping voltage ≤18.5 V is acceptable.

FAQ
What is the maximum allowable PCB trace length between D8V0X1B2LP-7B and the protected connector?
For optimal ESD performance, the trace length from the TVS device to the protected connector must be ≤3 mm. Longer traces introduce inductance that degrades clamping response, raising peak voltage seen by downstream ICs beyond the rated 18.5 V at 4 A. The recommended layout places the device directly adjacent to the connector pad with no vias or stubs.
Does D8V0X1B2LP-7B require external biasing or control signals?
No. D8V0X1B2LP-7B is a passive, bidirectional avalanche diode requiring no external power, bias, or control. It remains in high-impedance state below 9.5 V breakdown and automatically conducts during ESD transients to clamp voltage. Its operation is fully autonomous and compatible with AC-coupled or DC-biased signal lines.
Can D8V0X1B2LP-7B be used on 3.3 V logic I/O pins?
Yes. With a 8.0 V reverse working voltage (VRWM), D8V0X1B2LP-7B safely isolates 3.3 V signals during normal operation (IR ≤ 1 µA at VR = 8 V), while clamping ESD transients well above logic thresholds. Its 9.5 V minimum breakdown ensures no false triggering during 3.3 V rail noise or overshoot.
Is D8V0X1B2LP-7B qualified for automotive applications?
D8V0X1B2LP-7B is manufactured in IATF 16949-certified facilities and supports PPAP documentation, but it is not formally AEC-Q200 qualified. For automotive infotainment or ADAS applications requiring AEC-Q200, Diodes offers the automotive-grade variant D8V0X1B2LPQ-7B, which undergoes extended temperature cycling and humidity testing per AEC specifications.
