Product details
Overview
DF6D7M1N,LF from Toshiba Electronic Devices & Storage Corporation is a unidirectional ESD protection diode array in DFN6 package, designed for high-speed data line protection with 6 V working peak reverse voltage, ±8 kV IEC61000-4-2 contact ESD immunity, and 0.5 pF typical total capacitance. It serves as a transient voltage suppressor on USB 2.0, HDMI, or audio interface lines.
For engineers reviewing the DF6D7M1N,LF datasheet, DF6D7M1N,LF pinout, DF6D7M1N,LF application, or DF6D7M1N,LF equivalent, key selection criteria include clamp voltage at 1 A (≤12 V), dynamic resistance (≤0.9 Ω), low capacitance for signal integrity, and DFN6 footprint compatibility with space-constrained PCB layouts.
Technical Context
The DF6D7M1N,LF integrates two independent ESD protection channels in a single DFN6 package, each featuring a silicon epitaxial planar structure optimized for fast response to electrostatic transients. Its clamping behavior follows IEC61000-4-5 8/20 µs pulse conditions, with guaranteed VC ≤12 V at IPP = 1 A.
Dynamic resistance is characterized via TLP testing (Z₀ = 50 Ω, tp = 100 ns) across 3–8 A, yielding ≤0.9 Ω typical value-critical for minimizing voltage overshoot during ESD events. Total capacitance of 0.5 pF (typ.) at VR = 0 V, f = 1 MHz ensures minimal signal distortion on high-frequency interfaces.

| 2 | I/O 1 | Protected input/output line 1 - connects to high-speed signal trace requiring ESD hardening |
| 3 | I/O 2 | Protected input/output line 2 - independent channel for dual-line protection (e.g., D+ and D−) |
| 4 | NC | No internal connection - must be left floating or tied to GND per layout best practice |
| 5 | NC | No internal connection - must be left floating or tied to GND per layout best practice |
| 6 | NC | No internal connection - must be left floating or tied to GND per layout best practice |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 0.8 pF capacitance, ±8 kV IEC61000-4-2, SOT-553 package (1.6 × 1.6 mm same footprint) | Higher capacitance limits use to ≤100 Mbps interfaces; lacks guaranteed dynamic resistance spec | Select when footprint compatibility is critical and signal bandwidth <100 Mbps |
| ESD56081D05-2/TR | 0.35 pF capacitance, ±15 kV IEC61000-4-2, DFN6 package, but higher VRWM (5.5 V) | Lower VRWM restricts use to 3.3 V or lower systems; superior ESD rating for harsh environments | Select for ultra-high-speed interfaces (e.g., MIPI D-PHY) where sub-0.4 pF is mandatory |
Compared with TPD2E001DRYR and ESD56081D05-2/TR, DF6D7M1N,LF offers optimal balance of 0.5 pF capacitance, 6 V VRWM headroom for 5 V systems, and validated ≤0.9 Ω dynamic resistance-making it preferred for USB 2.0 and industrial DDC protection where signal fidelity and robust clamping are jointly required.

FAQ
What is the maximum working voltage supported by DF6D7M1N,LF?
The DF6D7M1N,LF has a working peak reverse voltage (VRWM) of 6 V, meaning it reliably blocks up to 6 V DC or peak AC signals without significant leakage. This makes DF6D7M1N,LF suitable for protecting 5 V logic interfaces such as USB 2.0 and HDMI DDC, where margin above nominal rail is essential for noise immunity and tolerance to voltage ripple.
Does DF6D7M1N,LF meet IEC61000-4-2 ESD immunity standards?
Yes, DF6D7M1N,LF is rated for ±8 kV contact discharge per IEC61000-4-2, with no functional or parametric degradation observed after testing. This certification is explicitly guaranteed in Toshiba's datasheet Rev. 5.0 and applies to both I/O 1 and I/O 2 channels independently, confirming DF6D7M1N,LF's suitability for end-equipment compliance testing.
What is the typical total capacitance of DF6D7M1N,LF and why does it matter?
DF6D7M1N,LF exhibits 0.5 pF typical total capacitance at 0 V and 1 MHz. This ultra-low value is critical for preserving signal integrity on high-speed interfaces: it minimizes insertion loss and maintains eye opening on USB 2.0 (480 Mbps) links, directly enabling DF6D7M1N,LF's deployment without degrading data transmission performance.
Can DF6D7M1N,LF be used for bidirectional signal lines like USB D+ and D−?
Yes, DF6D7M1N,LF is configured as a dual unidirectional diode array with common cathode (GND), allowing independent clamping of positive transients on I/O 1 and I/O 2 to ground. This architecture supports bidirectional data lines such as USB D+ and D−, where each line requires separate low-capacitance ESD suppression-exactly the function implemented by DF6D7M1N,LF.
What is the thermal limit and package type of DF6D7M1N,LF?
DF6D7M1N,LF uses a DFN6 package measuring 1.6 × 1.6 × 0.55 mm with an operating junction temperature range of −55 °C to +150 °C. Its 0.0017 g typical weight and exposed pad design support efficient heat dissipation during repeated ESD events, making DF6D7M1N,LF appropriate for thermally demanding industrial and automotive under-dash applications.
