Product details
Overview
DF2B6.8E,L3F from Toshiba is a unidirectional ESD protection diode designed for I/O line safeguarding in portable electronics, featuring a 5.0 V reverse stand-off voltage, 6.8 V typical breakdown voltage, 15 pF typical capacitance at 0 V, ±8 kV IEC61000-4-2 contact discharge immunity, and SOD-323 (SC-76) package.
For engineers reviewing the DF2B6.8E,L3F datasheet, DF2B6.8E,L3F pinout, DF2B6.8E,L3F application, or DF2B6.8E,L3F equivalent, key selection considerations include low-capacitance signal-line protection, guaranteed ESD robustness per IEC61000-4-2, strict non-voltage-regulation use restriction, and compatibility with high-speed USB 2.0, HDMI, and audio interface traces.
Technical Context
This device operates exclusively as a transient voltage suppression element for electrostatic discharge events - not as a Zener regulator or general-purpose rectifier. Its clamping behavior is defined by a sharp reverse breakdown at 5.8–7.8 V (IR = 1 mA), with leakage current ≤0.5 μA at 5 V VRWM and junction temperature rated to 150°C.
The SOD-323 package enables compact placement near connectors or IC pins, and its 15 pF total capacitance (measured at 0 V, 1 MHz) ensures minimal signal distortion on data lines up to ~200 Mbps. It is certified to withstand ±8 kV contact discharge per IEC61000-4-2 without functional degradation or parametric shift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 5.0 V - Maximum continuous working voltage before clamping begins; sets safe operating margin for 3.3 V/5 V data lines. |
| Breakdown Voltage (Typ.) | 6.8 V - Clamping initiates near this voltage under 1 mA test current; defines effective overvoltage threshold. |
| Total Capacitance | 15 pF - Measured at 0 V, 1 MHz; enables use on USB 2.0 and audio interfaces without signal integrity loss. |
| ESD Immunity | ±8 kV - IEC61000-4-2 contact discharge rating; qualifies for consumer-grade handheld and peripheral designs. |
| Power Dissipation | 150 mW - Rated on 20 mm × 20 mm FR-4 board with 4 mm × 4 mm pads; defines thermal derating envelope. |
| Junction Temperature | 150 °C - Maximum allowable die temperature; requires layout-aware thermal relief for sustained pulse conditions. |
Pinout & Package
SOD-323 (SC-76) surface-mount package: 1.7 mm × 1.25 mm × 0.9 mm body, gull-wing leads, cathode marked with band (K1 marking). Weight: 1.4 mg (typ.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input side of protected line | Connected to signal trace upstream of IC input; conducts during negative ESD transients. |
| Cathode | Ground reference node | Connected directly to low-inductance system ground plane; provides return path for clamped current. |
Key Features
| Feature | Design Value |
|---|---|
| IEC61000-4-2 ±8 kV Contact Rating | Guaranteed ESD survivability without parameter shift - eliminates need for post-test requalification in production test flow. |
| 15 pF Low Capacitance | Preserves edge rate and eye diagram integrity on 480 Mbps USB 2.0 differential pairs and analog audio paths. |
| Unidirectional Clamping Architecture | Protects only against negative transients on anode-to-ground path; avoids forward conduction on positive surges. |
| 5.0 V Reverse Stand-off | Provides 1.7 V margin above 3.3 V logic rails - prevents false triggering during normal operation or noise spikes. |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Channels |
|---|---|
Use Scenario: Protecting DP/DM lines in smartphones, tablets, and docking stations from user-handling ESD events. IC Role / Device Role / Timing Role: Passive clamping diode placed within 3 mm of connector, shunting surge current to ground before reaching USB transceiver. Use Value: Maintains 480 Mbps signaling integrity while surviving repeated ±8 kV contact discharges per IEC standard. | Use Scenario: Safeguarding low-speed DDC (Display Data Channel) and CEC (Consumer Electronics Control) lines in TVs and AV receivers. IC Role / Device Role / Timing Role: Ground-referenced transient suppressor on 5 V-tolerant I²C-compatible buses with <100 kHz clock rates. Use Value: Prevents latch-up or register corruption in HDMI controller ICs during plug/unplug events. |
| Smartphone Audio Jacks | Industrial HMI Touch Panels |
Use Scenario: Shielding 3.5 mm TRRS microphone and headset detection lines from human-body-model ESD. IC Role / Device Role / Timing Role: Anode tied to mic bias or sense line; cathode to clean analog ground; blocks >5 kV transients without loading DC bias. Use Value: Eliminates pop/click artifacts and false button presses caused by ESD-induced voltage glitches. | Use Scenario: Protecting projected capacitive touch controller I/Os in factory-floor HMIs exposed to frequent operator contact. IC Role / Device Role / Timing Role: Point-of-entry suppressor on X/Y electrode traces, placed adjacent to FPC connector to minimize loop inductance. Use Value: Ensures uninterrupted touch reporting after repeated ±8 kV discharges - critical for uptime in automated environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NZQ6V8AXV5T1G | Same SOD-323 package; 6.8 V breakdown; 18 pF capacitance; ±8 kV IEC61000-4-2 rating. | Slightly higher capacitance may affect margin on 480 Mbps USB; otherwise functionally interchangeable. | Select when sourcing diversification is required and 3 pF extra capacitance is acceptable in target layout. |
| Vishay ESDBLE5.0D1W | Bi-directional configuration; 5.0 V stand-off; 12 pF capacitance; ±8 kV rating; same footprint. | Clamps both polarities - suitable where positive transients dominate or ground bounce is asymmetric. | Prefer for mixed-signal interfaces with undefined voltage polarity or shared ground-return paths. |
Compared with NZQ6V8AXV5T1G and ESDBLE5.0D1W, the DF2B6.8E,L3F offers the lowest capacitance among unidirectional 6.8 V options and strict compliance with Toshiba's ESD-only usage mandate - making it optimal for bandwidth-sensitive, single-polarity signal lines where design control over transient direction is assured.

FAQ
What is the primary function of the DF2B6.8E,L3F?
The DF2B6.8E,L3F is a unidirectional ESD protection diode intended solely for safeguarding signal lines against electrostatic discharge events. It is explicitly not rated or qualified for constant-voltage regulation, rectification, or surge suppression beyond IEC61000-4-2 levels. Its design centers on fast clamping response, low capacitance, and guaranteed ±8 kV contact discharge immunity - all verified per Toshiba's published test reports for the DF2B6.8E,L3F.
Can the DF2B6.8E,L3F be used as a Zener diode for voltage regulation?
No. The DF2B6.8E,L3F is strictly designated for ESD protection only, as stated in Toshiba's official documentation. Its electrical characteristics - including wide breakdown tolerance (5.8–7.8 V), absence of Zener test conditions, and explicit "not intended for constant voltage diode application" disclaimer - preclude use as a voltage reference or regulator. Using DF2B6.8E,L3F in such roles violates its specified application scope and voids reliability guarantees.
What is the package type and mounting configuration of the DF2B6.8E,L3F?
The DF2B6.8E,L3F uses the SOD-323 (SC-76) surface-mount package: 1.7 mm × 1.25 mm × 0.9 mm body size with gull-wing leads and cathode indicated by a band. The marking "1-1G1A" appears on the top surface. This package supports reflow soldering per J-STD-020 and is optimized for placement within 3 mm of high-speed connectors to minimize inductive impedance during ESD clamping - a key requirement validated in Toshiba's layout guidelines for the DF2B6.8E,L3F.
How does the DF2B6.8E,L3F perform under IEC61000-4-2 testing?
The DF2B6.8E,L3F is rated for ±8 kV contact discharge per IEC61000-4-2, with zero functional or parametric failure observed across full qualification lots. This rating applies under standard test conditions (150 pF/330 Ω network, 0.75 ns rise time) and confirms robustness for consumer electronics handling scenarios. Toshiba specifies no degradation in VRWM, IR, or CT after stress - a performance benchmark confirmed in the official DF2B6.8E,L3F reliability report.
Is the DF2B6.8E,L3F RoHS compliant and halogen-free?
Yes. The DF2B6.8E,L3F meets EU RoHS Directive 2011/65/EU requirements and is halogen-free per JEDEC JS709A. Lead content is below 1000 ppm, and brominated flame retardants are absent. Compliance is documented in Toshiba's material declaration for the DF2B6.8E,L3F, with full substance-level reporting available upon request through Aetrix Electronics' technical support portal.
