Product details
Overview
DF5A6.8JE from Toshiba is a quad-channel ESD protection diode array designed for high-density I/O line protection in portable electronics. It features 6.8 V nominal Zener voltage (IZ = 5 mA), ≤25 Ω dynamic impedance, 45 pF typical terminal capacitance at 1 MHz, and ±30 kV IEC61000-4-2 contact discharge immunity - deployed on USB, HDMI, and SD card interfaces.
For engineers reviewing the DF5A6.8JE datasheet, DF5A6.8JE pinout, DF5A6.8JE application, or DF5A6.8JE equivalent, key selection criteria include low-capacitance multi-line ESD clamping, ultra-compact 1−2W1A package footprint, guaranteed ±30 kV ESD robustness, and strict non-voltage-regulation use restriction per Toshiba's specification.
Technical Context
The DF5A6.8JE integrates four independent cathode-anode ESD clamp structures in a single SOT-323-5 (1−2W1A) package, with shared anode connection (Pin 2) and isolated cathodes (Pins 1, 3, 4, 5). Each channel operates as a bidirectional Zener-type transient voltage suppressor optimized for fast ESD pulse absorption without DC regulation duty.
Its electrical behavior is defined by a 6.4–7.2 V Zener voltage window at 5 mA, sub-0.5 μA reverse leakage at 5 V, and stable 45 pF capacitance across 0–6 V reverse bias - enabling signal integrity preservation on high-speed digital lines up to ~300 Mbps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage (VZ) | 6.4–7.2 V at IZ = 5 mA - defines clamping threshold for ESD transients on protected lines |
| Dynamic impedance (ZZ) | ≤25 Ω - ensures low-voltage overshoot during 8/20 μs surge events |
| Terminal capacitance (CT) | 45 pF typical at f = 1 MHz, VR = 0 V - supports USB 2.0 and SDIO interface speeds |
| ESD immunity | ±30 kV per IEC61000-4-2 contact discharge - exceeds industrial and consumer immunity requirements |
| Power dissipation (P) | 100 mW - limits thermal stress during repetitive ESD events in compact layouts |
| Junction temperature (Tj) | 150 °C maximum - sets upper boundary for PCB layout derating in sealed enclosures |
Pinout & Package
DF5A6.8JE uses the Toshiba 1−2W1A package - a 5-pin SOT-323 variant with gull-wing leads, 1.25 mm × 1.25 mm body, and 0.65 mm pitch. Pin 2 is the common anode; Pins 1, 3, 4, and 5 are individual cathodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CATHODE1) | ESD clamp cathode | Connects to first protected I/O line (e.g., USB D+) |
| 2 (ANODE) | Common anode node | Shared return path to ground or low-impedance reference plane |
| 3 (CATHODE2) | ESD clamp cathode | Connects to second protected I/O line (e.g., USB D−) |
| 4 (CATHODE3) | ESD clamp cathode | Connects to third protected I/O line (e.g., HDMI HPD) |
| 5 (CATHODE4) | ESD clamp cathode | Connects to fourth protected I/O line (e.g., SD DAT0) |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel ESD protection | Four independent clamps in one 1.25 × 1.25 mm package - reduces board area vs. discrete diodes |
| Low 45 pF capacitance | Preserves signal rise time on 480 Mbps USB 2.0 differential pairs without added jitter |
| ±30 kV IEC61000-4-2 rating | Eliminates need for secondary ESD stages in handheld device front-end designs |
| No DC regulation function | Explicitly restricted to ESD-only use - prevents misuse as Zener voltage reference or shunt regulator |
Applications
| USB 2.0 Interface Protection | HDMI Hot-Plug Detection (HPD) |
|---|---|
Use Scenario: Protecting D+/D− differential pair and ID pin in smartphone USB OTG circuits against user-handling ESD. IC Role / Device Role: Bidirectional transient voltage clamp placed between connector and PHY IC input pins. Use Value: 45 pF capacitance avoids signal integrity degradation while delivering ±30 kV contact discharge immunity per line. | Use Scenario: Safeguarding HDMI HPD line in set-top boxes exposed to repeated cable insertion/removal events. IC Role / Device Role: Low-leakage (≤0.5 μA at 5 V) ESD clamp isolating HPD from downstream controller GPIO. Use Value: Prevents false HPD toggling and system reset caused by ESD-induced latch-up on 5 V-tolerant inputs. |
| SD Card Interface Protection | Mobile Display Data Lines |
Use Scenario: Shielding SDIO DAT0–DAT3 and CMD lines in wearable devices where space constraints limit discrete protection. IC Role / Device Role: Quad-channel clamping device with shared anode tied to system ground plane. Use Value: Reduces component count by 4× versus single-diode solutions while maintaining <1 mm² footprint. | Use Scenario: Protecting MIPI D-PHY data lanes (CLK/HS/LP) in OLED display modules subjected to factory handling ESD. IC Role / Device Role: Capacitance-matched ESD suppressor placed directly at flex connector entry point. Use Value: 45 pF typical CT aligns with MIPI timing budgets for 1 Gbps lane operation without equalization overhead. |
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 NZQ6V8 | Single-channel, 6.8 V Zener, 55 pF CT, SOD-523 package | Requires four separate placements; higher total capacitance per line | Preferred when board layout allows discrete placement and thermal isolation per line is required |
| Vishay VEML6040 | Not applicable - optical sensor, not ESD protection device | N/A - incorrect functional category | Excluded: VEML6040 is ambient light sensor; not a valid alternative |
Compared with NZQ6V8, DF5A6.8JE delivers 4-channel integration and 10 pF lower capacitance per channel in half the PCB area, but requires shared anode routing; VEML6040 is unrelated and must be excluded from ESD protection evaluation.

FAQ
Is DF5A6.8JE rated for continuous DC voltage regulation?
No. DF5A6.8JE is explicitly designated by Toshiba for ESD protection only and must not be used as a Zener voltage reference or shunt regulator. Its electrical specifications - including Zener voltage tolerance and dynamic impedance - are validated solely under transient ESD stress conditions, not steady-state DC operation. Using DF5A6.8JE for constant-voltage applications violates its design intent and may result in premature failure.
What is the correct PCB layout practice for DF5A6.8JE's common anode (Pin 2)?
Pin 2 must connect directly to a low-inductance ground plane via multiple vias within 2 mm of the package, minimizing loop inductance for effective ESD current shunting. Avoid daisy-chaining or routing through series resistors. DF5A6.8JE's clamping efficiency depends critically on this low-impedance return path - poor grounding degrades its ±30 kV IEC61000-4-2 performance and increases voltage overshoot on protected lines.
Can DF5A6.8JE protect high-speed differential signals like USB 3.0 or PCIe?
No. DF5A6.8JE's 45 pF terminal capacitance exceeds the <1 pF requirement for USB 3.0 SuperSpeed and PCIe Gen1+ signaling. It is qualified only for USB 2.0 (480 Mbps), SDIO, HDMI HPD, and other sub-500 Mbps interfaces. For higher-speed applications, Toshiba offers dedicated low-capacitance arrays such as DF2S6.8M, which specifies 0.6 pF per channel.
Does DF5A6.8JE meet RoHS and REACH compliance?
Yes. DF5A6.8JE conforms to EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed by Toshiba's material declarations and manufacturing records. Lead-free soldering compatible up to JEDEC J-STD-020C MSL Level 1, with peak reflow temperature of 260 °C. Full compliance documentation is available upon request from Aetrix Electronics.
What is the maximum number of ESD strikes DF5A6.8JE can withstand before degradation?
Toshiba does not specify a cycle life rating for DF5A6.8JE. Its ±30 kV IEC61000-4-2 qualification reflects single-event survivability under standardized test conditions - not cumulative endurance. Repeated exposure above 15 kV contact discharge may cause parametric shift in VZ or increased leakage. For mission-critical systems requiring multi-strike resilience, DF5A6.8JE should be paired with upstream filtering or used in conjunction with higher-energy TVS devices.
