Product details
Overview
DF5A6.2LJE from TOSHIBA is a quad-channel ESD protection diode array designed for high-speed data lines, featuring 6.2 V nominal Zener voltage, 6.5 pF typical terminal capacitance, ±8 kV IEC61000-4-2 contact discharge immunity, and ultra-compact 5-pin SOT-353 (1-2W1A) package. It serves as transient voltage suppression at USB, HDMI, or audio interface inputs.
For engineers reviewing the DF5A6.2LJE datasheet, DF5A6.2LJE pinout, DF5A6.2LJE application, or DF5A6.2LJE equivalent, key selection criteria include low-capacitance ESD clamping for signal integrity preservation, multi-line protection in minimal board area, and compliance with industrial-grade ESD immunity requirements without DC voltage regulation capability.
Technical Context
This device implements four independent Zener-based ESD clamps in a single monolithic silicon die, each with cathode-anode junctions optimized for fast response (<1 ns) to electrostatic transients. It operates strictly as a transient suppressor - not a voltage regulator - with no specified forward conduction rating or continuous power handling beyond 100 mW peak dissipation.
The 6.5 pF capacitance is measured at 0 V reverse bias and 1 MHz, enabling use on lines up to 100 Mbps without significant signal degradation. Its ±8 kV IEC61000-4-2 rating applies only to contact discharge; air discharge level is not guaranteed per datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage (VZ) | 6.2 V typ. at 5 mA - defines clamping threshold during ESD event; not intended for steady-state voltage regulation |
| Terminal capacitance (CT) | 6.5 pF typ. at 0 V, 1 MHz - enables use on high-speed interfaces (e.g., USB 2.0, I²C) without signal distortion |
| ESD immunity | ±8 kV contact discharge per IEC61000-4-2 - validated clamping performance with no functional damage after test |
| Power dissipation (P) | 100 mW max - limits sustained energy absorption; transient pulses must remain within this thermal envelope |
| Junction temperature (Tj) | 150 °C max - sets upper thermal limit for reliability; derating required above 25 °C ambient |
| Reverse leakage (IR) | 2.5 µA max at 5 V - ensures minimal standby current draw on protected signal lines |
Pinout & Package
DF5A6.2LJE uses the JEDEC-compatible 5-pin SOT-353 package (TOSHIBA code: 1-2W1A), measuring 2.1 × 1.25 × 0.9 mm, with exposed pad omitted. Pin 1 is Cathode 1; Pin 2 is Anode (common anode configuration); Pins 3–5 are Cathodes 2–4 respectively.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD clamp output for first protected line; connects to I/O trace before connector |
| 2 | Anode (common) | Shared return path to ground or low-impedance reference; must be routed with minimal inductance |
| 3 | Cathode 2 | ESD clamp output for second protected line; electrically isolated from Cathode 1 |
| 4 | Cathode 3 | ESD clamp output for third protected line; independent junction, same VZ tolerance |
| 5 | Cathode 4 | ESD clamp output for fourth protected line; enables 4-line protection in <2.6 mm² footprint |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel ESD protection | Four independent 6.2 V Zener clamps in one SOT-353 package - reduces BOM count and PCB real estate vs. discrete diodes |
| Low terminal capacitance | 6.5 pF typical between cathode and anode - preserves signal rise/fall times on data lines up to 100 Mbps |
| IEC61000-4-2 certified | ±8 kV contact discharge immunity with zero functional failure - meets industrial and consumer ESD compliance requirements |
| Common-anode architecture | Single anode (Pin 2) shared across all four cathodes - simplifies grounding layout and minimizes loop inductance |
Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
Use Scenario: Protecting differential USB 2.0 D+ and D− lines against user-handling ESD events near connectors. IC Role / Device Role / Timing Role: Transient voltage suppressor clamping excursions above 6.2 V while maintaining sub-7 pF loading on both lines. Use Value: Prevents latch-up or damage to USB transceivers without degrading 480 Mbps eye diagram integrity. | Use Scenario: Safeguarding HDMI Display Data Channel (DDC) I²C bus (SCL/SDA) from ESD during cable insertion. IC Role / Device Role / Timing Role: Bidirectional ESD clamp on two open-drain lines sharing common ground return via Pin 2. Use Value: Enables robust hot-plug operation while preserving I²C timing margins under 100 kHz clock rate. |
| Smartphone Audio Jack | Industrial Sensor Interface |
Use Scenario: Shielding 3.5 mm TRRS audio jack contacts (mic, left/right, ground) from human-body-model ESD. IC Role / Device Role / Timing Role: Four-cathode array assigning one clamp per active conductor, with common anode tied to chassis ground. Use Value: Eliminates need for four separate 0402 diodes, reducing assembly cost and improving layout consistency. | Use Scenario: Protecting analog sensor outputs (e.g., pressure, temperature) connected to microcontroller ADC inputs. IC Role / Device Role / Timing Role: Low-leakage (≤2.5 µA) clamp preventing overvoltage damage during field maintenance or cable routing. Use Value: Maintains DC accuracy of mV-level signals while providing ±8 kV ESD robustness per line. |
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 NZQ6V2B | Same 6.2 V VZ, 7.0 pF CT, SOT-353 package, but rated for ±15 kV air discharge (IEC61000-4-2) | Higher air-discharge immunity supports harsher environments (e.g., factory floor equipment) | Select NZQ6V2B when air discharge testing is mandated; DF5A6.2LJE remains optimal where only contact discharge is required |
| Vishay VEML6030X01 | Not applicable - optical sensor IC; excluded due to functional mismatch | N/A | Not a valid alternative; excluded per verification against manufacturer documentation |
Compared with NZQ6V2B, DF5A6.2LJE offers lower capacitance (6.5 pF vs. 7.0 pF) for marginally better high-speed signal fidelity, while NZQ6V2B provides broader ESD test coverage. Neither is pin-compatible with DF5A6.2LJE due to differing internal topology and cathode/anode assignments.

FAQ
Is DF5A6.2LJE suitable for continuous DC voltage regulation?
No. DF5A6.2LJE is explicitly designated for ESD protection only, not for constant-voltage applications. Its Zener voltage specification applies solely during transient clamping events. The datasheet prohibits use as a voltage reference or regulator. DF5A6.2LJE lacks guaranteed dynamic impedance stability or power derating curves required for regulated operation.
What is the maximum recommended trace length between DF5A6.2LJE and the protected I/O pin?
For optimal ESD performance, keep the trace from the DF5A6.2LJE cathode to the protected I/O pin under 3 mm, and route the common anode (Pin 2) directly to a low-inductance ground plane. Longer traces increase inductance, delaying clamping response and permitting voltage overshoot beyond DF5A6.2LJE's 6.2 V threshold during fast transients.
Does DF5A6.2LJE support bidirectional signal lines like I²C?
Yes. DF5A6.2LJE's Zener-based structure provides symmetrical clamping for both positive and negative ESD transients on any cathode line relative to the common anode. This makes DF5A6.2LJE appropriate for bidirectional buses such as I²C SDA/SCL, provided the anode is tied to a stable reference (e.g., ground or VIO).
Can DF5A6.2LJE replace a single-channel ESD diode in a design?
Yes, but only when protecting exactly four signal lines with matched clamping behavior. DF5A6.2LJE integrates four channels in one package - using it for fewer lines wastes pins and may complicate layout. For single-line protection, discrete alternatives like DF2S6.8F are more appropriate than DF5A6.2LJE.
What is the RoHS status of DF5A6.2LJE?
DF5A6.2LJE is RoHS-compliant per Toshiba's official product documentation and environmental reports. Lead content is below 0.1 wt%, and all six restricted substances meet EU Directive 2011/65/EU requirements. Full compliance data is available through Toshiba's environmental portal using the DF5A6.2LJE part number.
