Product details
Overview
DESD6V8DLPA-7B from Diodes Incorporated is a dual-channel surface-mount transient voltage suppression (TVS) diode array designed for bidirectional ESD protection of high-speed data lines. It features 5.25V reverse standoff voltage, ±8kV contact/±16kV air IEC 61000-4-2 ESD rating, 40pF typical capacitance, and 70W peak pulse power-optimized for USB 2.0, HDMI, and audio interface protection in portable electronics.
For engineers reviewing the DESD6V8DLPA-7B datasheet, DESD6V8DLPA-7B pinout, DESD6V8DLPA-7B application, or DESD6V8DLPA-7B equivalent, key selection criteria include low clamping voltage (≤12.5V @ 1A), sub-1µA leakage at VRWM, dual-channel symmetry, and X1-DFN1006-3 footprint compatibility with automated SMT assembly.
Technical Context
This dual TVS array integrates two identical, back-to-back Zener structures in a single compact package to provide symmetrical bidirectional clamping for differential or single-ended signal lines. Each channel operates independently with matched breakdown (6.4–7.2V) and clamping characteristics (VC ≤12.5V @ IPP = 1A).
Its 40pF total capacitance at 0V bias and low dynamic impedance (≤30Ω) ensure minimal signal distortion on high-frequency interfaces up to 480 Mbps. The device meets MIL-STD-883C HBM (8kV) and IEC 61000-4-2 Level 4, making it suitable for consumer and industrial end-equipment requiring robust electrostatic immunity without compromising signal integrity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A-Q | Single-channel, higher 5.0V VRWM, 600W PPK, SMA package (4.5×2.7 mm) | Requires two devices for dual-line protection; larger footprint; better for high-energy surges but unsuitable for space-constrained USB/HDMI layouts. | Select when peak surge energy exceeds 70W and board area permits discrete placement. |
| TPD2E001DRYR | Single-channel, 5.5V VRWM, 12pF capacitance, same X2SON-4 package size but different pinout (no shared cathode) | Lower capacitance ideal for USB 3.0; lacks dual-channel integration-requires two units and separate ground connections. | Choose for ultra-low-capacitance needs (>1Gbps interfaces) where dual-channel symmetry is secondary to signal fidelity. |
Compared with SMA6J5.0A-Q and TPD2E001DRYR, DESD6V8DLPA-7B uniquely delivers dual-channel symmetry, 40pF capacitance, and X1-DFN1006-3 footprint in one device-making it optimal for compact, cost-sensitive, high-volume USB 2.0 and HDMI DDC protection where layout density and ESD reliability are jointly critical.

FAQ
What is the maximum clamping voltage of DESD6V8DLPA-7B at 1A peak pulse current?
The clamping voltage is guaranteed ≤12.5V under an 8×20µs waveform at 1A peak pulse current, measured per Figure 4 in DS44485 Rev. 1–2. This value reflects worst-case device behavior across temperature (–55°C to +150°C) and process variation, ensuring downstream ICs see limited overvoltage stress during ESD transients.
Can DESD6V8DLPA-7B be used for unidirectional protection?
No-it is inherently bidirectional due to its dual-Zener back-to-back configuration. Each channel conducts symmetrically for both positive and negative transients. For unidirectional applications (e.g., DC power rail protection), a single-anode/cathode TVS like P6SMB5.0A is required; this device is optimized exclusively for signal-line ESD suppression.
Is the X1-DFN1006-3 package compatible with standard reflow profiles?
Yes-the package is qualified for lead-free reflow per J-STD-020 Level 1 (MSL1), supporting peak temperatures up to 260°C. Its 0.5 mm profile and NiPdAu terminal finish ensure reliable wetting and void-free solder joints using standard Type 3 or Type 4 solder paste and industry-standard thermal profiles.
Does DESD6V8DLPA-7B meet AEC-Q200 requirements?
While not individually AEC-Q200 certified, it is manufactured in IATF 16949-certified facilities and supports automotive qualification pathways. Diodes states that parts meeting AEC-Q200 can be supplied upon request with PPAP documentation-confirm specific automotive grade requirements directly with Diodes' automotive team prior to design-in.
