Product details
Overview
DF5A6.8LJE from TOSHIBA is a quad-channel ESD protection diode array designed for high-speed data lines, featuring 6.8 V nominal Zener voltage (VZ = 6.5–7.1 V at IZ = 5 mA), low terminal capacitance (CT = 6.0 pF typ. at 1 MHz), and ±8 kV IEC61000-4-2 contact discharge immunity. It is used in USB 2.0, HDMI, and audio interface protection.
For engineers reviewing the DF5A6.8LJE datasheet, DF5A6.8LJE pinout, DF5A6.8LJE application, or DF5A6.8LJE equivalent, key selection considerations include its ultra-compact 5-pin SOT-353 package, quad-cathode architecture, low clamping voltage under ESD stress, and strict limitation to ESD-only use-excluding constant-voltage regulation.
Technical Context
The DF5A6.8LJE integrates four independent Zener-type ESD clamps in a single SOT-353 package, with shared anode (Pin 2) and individual cathodes (Pins 1, 3, 4, 5). Each channel operates as a bidirectional transient voltage suppressor optimized for fast-rising ESD pulses.
It complies with IEC61000-4-2 Level 4 (±8 kV contact), exhibits low dynamic impedance (ZZ ≤ 50 Ω), and maintains reverse leakage current ≤ 0.5 μA at VR = 5 V-enabling minimal signal distortion on high-frequency lines up to ~500 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage VZ | 6.5–7.1 V at IZ = 5 mA - defines clamping threshold during ESD events |
| Terminal capacitance CT | 6.0 pF typ. at VR = 0 V, f = 1 MHz - enables <500 MHz signal integrity retention |
| ESD immunity | ±8 kV per IEC61000-4-2 contact discharge - meets industrial-grade surge robustness |
| Power dissipation P | 100 mW - limits sustained power handling; intended for transient-only operation |
| Reverse leakage IR | ≤0.5 μA at VR = 5 V - ensures negligible DC loading on protected lines |
| Junction temperature Tj | 150°C max - constrains thermal design margin in compact PCB layouts |
Pinout & Package
DF5A6.8LJE uses a 5-pin SOT-353 (JEDEC TO-236AB) package with 1.25 mm × 2.1 mm footprint and 0.003 g mass. Pin 2 is common anode; Pins 1, 3, 4, and 5 are isolated cathodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD clamp output for Channel 1 signal line (e.g., USB D+) |
| 2 | Anode (common) | Shared return path to ground or low-impedance reference plane |
| 3 | Cathode 2 | ESD clamp output for Channel 2 signal line (e.g., USB D−) |
| 4 | Cathode 3 | ESD clamp output for Channel 3 signal line (e.g., HDMI TMDS Clock) |
| 5 | Cathode 4 | ESD clamp output for Channel 4 signal line (e.g., HDMI TMDS Data 0) |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel integration | Four independent ESD clamps in one SOT-353 - reduces board area by >75% vs. discrete diodes |
| Low capacitance | 6.0 pF typical - preserves signal rise/fall times on 480 Mbps USB 2.0 lines |
| IEC61000-4-2 compliance | ±8 kV contact discharge - satisfies EN 61000-4-2 Level 4 for end-equipment certification |
| ESD-only specification | No Zener regulation rating - prohibits use as voltage reference or steady-state shunt regulator |
Applications
| USB 2.0 Interface Protection | HDMI TMDS Line Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Single-channel, 0.5 pF CT, ±8 kV IEC61000-4-2, SOT-553 package | Requires four separate placements; lower capacitance but higher assembly cost | Preferred when ultra-low capacitance (<1 pF) is critical and layout space allows discrete placement |
| ESD5Z6.8T5G | Single-channel, 6.8 V VZ, 12 pF CT, SOD-523, ±8 kV IEC61000-4-2 | Higher capacitance limits use to ≤100 Mbps interfaces; no multi-channel integration | Used where cost-per-channel is prioritized over board space and high-speed performance |
Compared with TPD2E001DRYR and ESD5Z6.8T5G, the DF5A6.8LJE uniquely delivers quad-channel protection with 6.0 pF capacitance in a single 5-pin SOT-353-reducing component count, placement time, and parasitic inductance versus discrete alternatives, while remaining strictly limited to ESD-only duty.

FAQ
What is the primary function of the DF5A6.8LJE?
The DF5A6.8LJE is a quad-channel ESD protection diode array designed exclusively for electrostatic discharge suppression on high-speed signal lines. It is not rated for continuous Zener regulation or voltage reference use. Each channel clamps transients above ~6.8 V using a Zener-based structure, with guaranteed ±8 kV IEC61000-4-2 contact discharge immunity. Its 6.0 pF capacitance ensures compatibility with USB 2.0 and HDMI signals.
Can DF5A6.8LJE be used as a voltage regulator?
No. The DF5A6.8LJE is explicitly restricted to ESD protection only, as stated in Toshiba's documentation: "This product is for protection against electrostatic discharge (ESD) only and is not intended for any other usage, including without limitation, the constant voltage diode application." It lacks specifications for regulation accuracy, temperature coefficient, or long-term power dissipation required for Zener regulator use.
What is the pin configuration and connection method for DF5A6.8LJE?
The DF5A6.8LJE uses a 5-pin SOT-353 package with Pin 2 as the common anode and Pins 1, 3, 4, and 5 as individual cathodes. In circuit, the anode connects to ground or a low-impedance reference, while each cathode connects to a protected signal line. This architecture enables four independent clamping paths sharing one return node, minimizing layout inductance and PCB area.
Does DF5A6.8LJE meet international ESD standards?
Yes. The DF5A6.8LJE is certified to IEC61000-4-2 Level 4 for contact discharge at ±8 kV, with no device element damage observed under test conditions. This rating is verified per Toshiba's guaranteed ESD immunity specification and supports compliance with end-equipment standards such as EN 55032 and FCC Part 15 for consumer and industrial electronics.
What is the maximum operating temperature range for DF5A6.8LJE?
The DF5A6.8LJE has a storage temperature range of −55°C to +150°C and a maximum junction temperature (Tj) of 150°C. Its absolute maximum power dissipation is 100 mW at Ta = 25°C. Because it is intended only for transient ESD suppression-not continuous power handling-thermal design must ensure short-duration pulse energy does not exceed this limit, especially in high-density layouts.
