Product details
Overview
TPD6V8LP-7 from Diodes Incorporated is a unidirectional transient voltage suppressor (TVS) diode in a X1-DFN1006-2 leadless package, rated for 5 V reverse standoff voltage, 6.4–7.2 V breakdown at 5 mA, and clamping at 19 V under 4.5 A peak pulse current (8/20 µs). It delivers 85 W peak pulse power and 65 pF typical capacitance, designed for ESD protection of high-speed data lines such as USB 2.0 and HDMI interfaces.
For engineers reviewing the TPD6V8LP-7 datasheet, TPD6V8LP-7 pinout, TPD6V8LP-7 application, or TPD6V8LP-7 equivalent, key selection criteria include clamping voltage margin versus I/O rail tolerance, low capacitance for signal integrity, thermal derating on FR-4 PCBs, and automotive-grade qualification status - especially given its AEC-Q101 readiness and IATF 16949 manufacturing origin.
Technical Context
The TPD6V8LP-7 implements a planar silicon junction structure optimized for fast response to ESD transients (IEC61000-4-2 ±25 kV air, ±8 kV contact) while maintaining low leakage (<0.5 µA at 5 V) and stable breakdown characteristics across -65°C to +150°C. Its unidirectional configuration enables integration into DC-biased signal paths without forward conduction interference.
Thermal design relies on the X1-DFN1006-2 package's 500 °C/W junction-to-ambient resistance and 250 mW steady-state power dissipation limit, with derating required above 25°C ambient per Figure 1. The NiPdAu-plated copper leadframe ensures solderability per MIL-STD-202, Method 208 and supports automated reflow assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous DC or RMS voltage the device blocks without clamping in normal operation. |
| Breakdown Voltage | 6.4–7.2 V @ 5 mA - Confirmed voltage threshold where avalanche conduction begins; defines minimum overvoltage trip point. |
| Clamping Voltage | 19 V @ 4.5 A (8/20 µs) - Peak voltage seen by protected circuit during worst-case surge; determines downstream IC survivability margin. |
| Peak Pulse Power | 85 W - Maximum transient energy absorption capability under standardized 8/20 µs waveform; validates robustness against IEC 61000-4-5 surges. |
| Total Capacitance | 65 pF @ 0 V, 1 MHz - Signal-line loading effect; low enough for <480 Mbps USB 2.0 compliance without eye diagram degradation. |
| ESD Rating | ±25 kV air / ±8 kV contact (IEC61000-4-2) - Confirmed immunity level for human-handling events in end-user environments. |
| Operating Temperature | -65°C to +150°C - Validated performance range for under-hood automotive and industrial control applications. |
Pinout & Package
Package: X1-DFN1006-2 - ultra-small, leadless, surface-mount package (1.0 × 0.6 mm footprint, 0.5 mm height), cathode marked by bar or dot on top surface; terminals are anode (Pin 1) and cathode (Pin 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Automated assembly compatibility | Leadless X1-DFN1006-2 footprint and NiPdAu plating ensure reliable reflow soldering in SMT lines. |
| AEC-Q101 readiness | Manufactured in IATF 16949-certified facilities with PPAP capability - suitable for automotive infotainment and body electronics. |
| Green material compliance | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets global environmental mandates. |
Applications
| USB 2.0 Interface Protection | HDMI Data Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− differential pairs in portable USB peripherals against ESD events during cable insertion or handling. IC Role / Device Role: Unidirectional TVS clamp placed between each data line and ground, leveraging 5 V standoff to avoid interfering with 3.3 V logic levels. Use Value: 19 V clamping ensures downstream USB transceiver ICs (e.g., TUSB2036) remain within absolute maximum ratings during ±8 kV contact discharge. | Use Scenario: Safeguarding TMDS clock and data channels in flat-panel display controllers against factory-floor ESD and user-touch transients. IC Role / Device Role: Low-capacitance TVS per channel, mounted adjacent to HDMI connector to minimize trace inductance and preserve signal rise/fall times. Use Value: 65 pF capacitance prevents measurable jitter or eye closure at 2.25 Gbps (HDMI 1.3), verified per HDMI compliance test procedures. |
| Automotive Infotainment Port | Industrial Sensor Interface |
Use Scenario: Shielding USB-C or micro-USB ports in head units and telematics modules exposed to harsh vehicle cabin environments. IC Role / Device Role: AEC-Q101-aligned TVS providing ESD resilience across extended temperature range (-40°C to +105°C ambient). Use Value: Stable 6.4–7.2 V breakdown and 19 V clamping maintained over full automotive temperature profile, ensuring consistent protection during cold cranking or hot soak. | Use Scenario: Guarding RS-485 or CAN FD transceiver I/O pins in programmable logic controllers subjected to field wiring ESD and induced surges. IC Role / Device Role: Bidirectional-capable unidirectional TVS used in conjunction with common-mode chokes to suppress both differential and common-mode transients. Use Value: 85 W peak pulse power rating handles repetitive 1 kV/500 Ω surge waveforms per IEC 61000-4-4 without parametric shift or failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD6V8LPN-7 | Successor part with identical electrical specs but enhanced process control and updated qualification documentation; same X1-DFN1006-2 package. | No functional change; intended for new designs requiring latest revision and long-term supply assurance. | Select TPD6V8LPN-7 for all new designs - Diodes explicitly states TPD6V8LP is not recommended for new designs. |
| SMAJ5.0A | DO-214AC package (larger, 4.5 × 2.7 mm), 5.0 V standoff, 6.4 V min breakdown, 19.2 V clamping @ 23.3 A - higher current rating but 150 pF capacitance. | Not suitable for high-speed data lines due to excessive capacitance; appropriate only for lower-frequency power/signal rails. | Use SMAJ5.0A only where board space permits and signal bandwidth <10 MHz; avoid for USB/HDMI. |
Compared with TPD6V8LP-7, the TPD6V8LPN-7 offers identical protection performance with improved long-term availability and documentation, while the SMAJ5.0A trades compact size and low capacitance for higher surge current handling - making it viable only in non-high-speed, space-tolerant applications.

FAQ
Is TPD6V8LP-7 qualified to AEC-Q101?
No, the TPD6V8LP-7 itself is not formally AEC-Q101 qualified, but it is manufactured in IATF 16949-certified facilities and supports PPAP documentation. Diodes states that automotive-grade versions (e.g., TPD6V8LPN-7Q) carry full AEC-Q101 certification - confirm qualification status via official Diodes Automotive Product Definitions page before use in safety-critical systems.
What is the recommended PCB pad layout for X1-DFN1006-2?
Diodes specifies a symmetrical two-pad layout matching the package's 0.65 mm pin pitch and 0.50 mm terminal width, with thermal relief vias recommended beneath the exposed pad area if present. Exact dimensions and solder mask clearance are published in Diodes' Package Outlines document X1-DFN1006-2, accessible at diodes.com/package-outlines.html.
Can TPD6V8LP-7 be used for bidirectional signal lines?
TPD6V8LP-7 is unidirectional and must be oriented with cathode toward the protected line's positive rail. For true bidirectional protection (e.g., RS-232 or AC-coupled lines), two devices in series opposition or a dedicated bidirectional TVS like PUSB3FR4 must be used - using a single TPD6V8LP-7 on bidirectional lines risks forward conduction and signal corruption.
Why does Diodes state "NOT RECOMMENDED FOR NEW DESIGNS"?
Diodes issued this notice because the TPD6V8LP-7 has been superseded by the TPD6V8LPN-7, which features refined process control, updated reliability testing, and formalized automotive qualification pathways. While TPD6V8LP-7 remains fully functional and supported for existing designs, new projects should adopt the PN variant to ensure long-term supply continuity and access to latest documentation and certifications.
