Diodes Incorporated DESD6V8DLP-7B

Overview

DESD6V8DLP-7B from Diodes Incorporated is a dual-channel, low-capacitance transient voltage suppression diode array designed for high-speed data line ESD protection in USB 2.0, HDMI, and audio interfaces. It features a 5.25 V reverse standoff voltage, 7.2 V maximum breakdown voltage, 40 pF typical capacitance at 0 V, 1.0 µA leakage at VRWM, and clamps to ≤12 V at 5 A (8/20 µs pulse).

For engineers reviewing the DESD6V8DLP-7B datasheet, DESD6V8DLP-7B pinout, DESD6V8DLP-7B application, or DESD6V8DLP-7B equivalent, key selection criteria include IEC 61000-4-2 Level 4 ESD robustness (±16 kV air / ±8 kV contact), low dynamic impedance (<30 Ω), and DFN1006-3 package compatibility with high-density PCB layouts.

Technical Context

This dual TVS array integrates two independent unidirectional ESD protection elements in a single X1-DFN1006-3 package, each with cathode-anode polarity defined by the bar marking. It operates as a clamping device during fast transients, leveraging silicon avalanche breakdown to limit voltage across protected lines while maintaining signal integrity via sub-40 pF capacitance.

The device meets MIL-STD-883C HBM ESD rating of 16 kV and supports automotive-grade reliability when qualified per AEC-Q101 - though this specific variant is not AEC-Q101 certified and carries the "NOT RECOMMENDED FOR NEW DESIGN" notice in its datasheet.

Key Specifications

Pinout & Package

Package: X1-DFN1006-3 - 1.0 × 0.6 mm, 0.5 mm height, 3-terminal leadless plastic package with NiPdAu-plated copper leadframe, moisture sensitivity level 1, and UL 94V-0 flammability rating.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel unidirectional TVS applications.

Compared with SMA6J5.0A-Q and SP1006-01UTG, DESD6V8DLP-7B uniquely balances dual-channel integration, 40 pF capacitance, and IEC Level 4 ESD rating in a 1.0 × 0.6 mm footprint - making it optimal for space-constrained USB 2.0 and HDMI 1.4 designs where moderate speed and compact layout are prioritized.

FAQ

Is DESD6V8DLP-7B AEC-Q101 qualified?

No. Although Diodes offers AEC-Q101-qualified variants in the same product family (e.g., DESD6V8DLPQ-7B), the DESD6V8DLP-7B part number is explicitly marked "NOT RECOMMENDED FOR NEW DESIGN" in its datasheet and lacks AEC-Q101 certification. It is intended for commercial and industrial applications only.

What is the correct PCB pad layout for X1-DFN1006-3?

The recommended footprint uses a 0.40 mm wide × 1.10 mm long solder pad (X1), 0.25 mm wide × 0.70 mm long thermal pad (Y1), and 0.30 mm gap (G1) between pads. Diodes specifies a 0.70 mm center-to-center spacing (C) and prohibits solder mask defined pads due to thermal relief requirements.

Can DESD6V8DLP-7B protect bidirectional data lines like I²C?

No. Its internal schematic shows two unidirectional elements sharing a cathode - suitable only for lines referenced to ground or VCC. For bidirectional buses such as I²C, a bidirectional TVS like D3V3Z5U-7 or SP3052-01UTG is required to clamp both positive and negative transients symmetrically.

Why does the datasheet list "NOT RECOMMENDED FOR NEW DESIGN"?

This notice indicates Diodes has superseded DESD6V8DLP-7B with enhanced variants (e.g., lower capacitance, AEC-Q101 qualification, or improved thermal performance). While fully functional and in active production, new designs should evaluate successors like DESD6V8DLPQ-7B to ensure long-term supply and specification alignment.
