Product details
Overview
DF5A6.2JE from TOSHIBA is a quad-channel ESD protection diode array designed for high-density I/O line protection in portable electronics. It features 6.2 V nominal Zener voltage (VZ = 5.8–6.6 V at IZ = 5 mA), ≤30 Ω dynamic impedance, 55 pF typical terminal capacitance, and ±30 kV IEC61000-4-2 contact discharge immunity. It is used on USB, HDMI, and audio interface lines to suppress transient overvoltage without signal distortion.
For engineers reviewing the DF5A6.2JE datasheet, DF5A6.2JE pinout, DF5A6.2JE application, or DF5A6.2JE equivalent, key selection criteria include its ultra-compact 1-2W1A package, four-cathode single-anode topology, low clamping voltage under ESD stress, and guaranteed ESD immunity level - all critical for space-constrained consumer interface protection designs.
Technical Context
The DF5A6.2JE implements a monolithic quad Zener-based ESD clamp structure with shared anode and individual cathodes, enabling independent protection of four signal lines. Its design targets fast response to sub-nanosecond ESD transients while maintaining low capacitance (55 pF typ.) to preserve high-speed signal integrity.
It operates strictly as a transient voltage suppression device - not a voltage regulation element - with no DC biasing capability beyond 3 V reverse leakage (≤1.0 μA). Junction temperature must be limited to 150°C, and continuous operation above rated power (100 mW) risks reliability degradation per Toshiba's derating guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage (VZ) | 5.8–6.6 V at IZ = 5 mA - defines clamping threshold during ESD events |
| Dynamic impedance (ZZ) | ≤30 Ω - ensures low-voltage overshoot during fast ESD pulses |
| Terminal capacitance (CT) | 55 pF typ. at VR = 0 V, f = 1 MHz - minimizes signal loading on high-speed interfaces |
| ESD immunity | ±30 kV contact discharge per IEC61000-4-2 - meets highest industrial ESD robustness class |
| Power dissipation (P) | 100 mW - limits thermal stress during repeated ESD strikes |
| Reverse leakage (IR) | ≤1.0 μA at VR = 3 V - avoids DC loading on protected signal lines |
Pinout & Package
DF5A6.2JE uses the ultra-compact surface-mount 1-2W1A package (JEDEC unregistered, Toshiba proprietary), measuring approximately 1.6 × 1.6 × 0.7 mm with 5 terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CATHODE1) | ESD clamp cathode | Protected signal line #1 connection point; clamps to common anode during overvoltage |
| 2 (ANODE) | Common anode | Shared return path for all four Zener clamps; connects to system ground or reference plane |
| 3 (CATHODE2) | ESD clamp cathode | Protected signal line #2 connection point; electrically isolated from other cathodes |
| 4 (CATHODE3) | ESD clamp cathode | Protected signal line #3 connection point; enables independent protection routing |
| 5 (CATHODE4) | ESD clamp cathode | Protected signal line #4 connection point; supports compact 4-line interface layouts |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel monolithic ESD array | Integrates four independent Zener clamps in one 1.6 × 1.6 mm package - reduces PCB area and assembly cost vs. discrete diodes |
| Low terminal capacitance | 55 pF typical - preserves signal integrity on USB 2.0, audio, and touch interface lines |
| High ESD immunity | ±30 kV contact discharge - exceeds IEC61000-4-2 Level 4, eliminating need for external TVS staging |
| Strict ESD-only function | No DC voltage regulation capability - prevents misuse as a Zener reference or shunt regulator |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detect |
|---|---|
Use Scenario: Protecting D+ and D− lines in smartphone USB ports against user-handling ESD events. IC Role / Device Role / Timing Role: Transient voltage clamp that activates within <1 ns to limit voltage to ≤12 V during ±8 kV air discharge. Use Value: Prevents PHY layer latch-up and data corruption while adding only 55 pF loading per line. | Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) pin from ESD during cable insertion/removal. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp referenced to system ground, responding to both positive and negative transients. Use Value: Maintains HPD logic-level fidelity (0–5 V) and avoids false plug/unplug detection caused by ESD-induced glitches. |
| Smartphone Audio Jack | Touchscreen I²C Bus |
Use Scenario: Shielding left/right audio and microphone paths in 3.5 mm TRRS jacks from human-body-model ESD. IC Role / Device Role / Timing Role: Four-cathode configuration allows simultaneous protection of tip, ring1, ring2, and sleeve contacts using single device. Use Value: Eliminates four discrete diodes and associated layout area, reducing BOM count and improving yield in tight mechanical envelopes. | Use Scenario: Protecting SDA/SCL lines between touchscreen controller and host processor against board-level ESD coupling. IC Role / Device Role / Timing Role: Low-leakage (≤1.0 μA) clamp that avoids pulling down I²C pull-up resistors during normal operation. Use Value: Ensures reliable bus communication at 400 kHz without signal rise-time degradation or false ACK/NACK errors. |
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 ESD9X5.0ST5G | Single-channel, 5.0 V VZ, 30 pF CT, SOT-523 package | Requires four devices for quad-line protection; lower capacitance but higher component count | Preferred when lowest possible capacitance (<30 pF) is mandatory and board space permits discrete placement |
| Vishay VEML6030X01 | Not applicable - optical ambient light sensor, unrelated function | N/A - incorrect product category | Excluded: misidentified part; not an ESD protection device |
Compared with DF5A6.2JE, ESD9X5.0ST5G offers lower capacitance but demands quadrupled placement effort and routing complexity; no valid alternative matches DF5A6.2JE's integrated quad-channel, 6.2 V clamping, and 1-2W1A footprint - making it uniquely suited for miniaturized interface protection where layout density and ESD margin are co-constrained.

FAQ
What is the primary function of the DF5A6.2JE?
The DF5A6.2JE is a quad-channel ESD protection diode array designed exclusively for transient voltage suppression on high-speed signal lines. It is not intended for DC voltage regulation or constant-current applications. Its Zener-based clamping action responds to electrostatic discharge events per IEC61000-4-2, with a nominal 6.2 V breakdown and ±30 kV immunity. DF5A6.2JE must never be used as a shunt regulator or reference diode.
Can DF5A6.2JE be used for voltage regulation?
No. DF5A6.2JE is explicitly restricted to ESD protection only, as stated in Toshiba's documentation. It lacks the stability, tolerance, and thermal characteristics required for voltage regulation. Its Zener voltage (5.8–6.6 V) is specified only under 5 mA test current and does not guarantee regulation performance under varying load or temperature. Using DF5A6.2JE for voltage regulation violates its designated use case and may result in field failure.
What is the significance of the 1-2W1A package designation for DF5A6.2JE?
The 1-2W1A is Toshiba's proprietary package code for a 5-terminal surface-mount device measuring 1.6 × 1.6 × 0.7 mm. It accommodates four cathodes and one shared anode in a compact footprint optimized for high-density PCB layouts. This package enables DF5A6.2JE to replace four discrete SOD-323 diodes, reducing mounting area by ~60% and assembly cost. JEDEC and JEITA do not assign standardized codes to this outline.
How does DF5A6.2JE achieve ±30 kV ESD immunity?
DF5A6.2JE achieves ±30 kV contact discharge immunity through monolithic integration of four low-impedance Zener junctions with optimized doping profiles and layout geometry. Its dynamic impedance stays ≤30 Ω during ESD transients, limiting peak clamped voltage to safe levels for downstream ICs. This performance is validated per IEC61000-4-2 testing methodology - not extrapolated - and applies only when mounted per Toshiba's recommended pad layout and grounding practices.
Is DF5A6.2JE RoHS compliant and lead-free?
Yes, DF5A6.2JE is RoHS compliant and lead-free, consistent with Toshiba's environmental policy and EU Directive 2011/65/EU. The device uses matte tin plating on external terminals and halogen-free molding compound. Full compliance documentation, including material declarations and test reports, is available through Toshiba's official support channels and authorized distributors. DF5A6.2JE meets J-STD-609 Category 1 marking requirements for lead-free identification.
