Product details
Overview
DF5A5.6CJE from TOSHIBA is a quad-channel ESD protection diode array designed for high-speed data lines, featuring 5.6 V nominal Zener voltage, 29 pF typical terminal capacitance, ±30 kV IEC61000-4-2 contact discharge immunity, and ultra-compact 1-2W1A surface-mount package. It serves as transient voltage suppression at USB 2.0, HDMI, or audio interface inputs.
For engineers reviewing the DF5A5.6CJE datasheet, DF5A5.6CJE pinout, DF5A5.6CJE application, or DF5A5.6CJE equivalent, key selection criteria include low-capacitance signal integrity preservation, multi-line ESD co-packaging, strict non-Zener-use restriction, and JEITA-compliant mounting geometry for space-constrained consumer electronics.
Technical Context
This device implements four independent cathode-anode ESD clamping paths in a single SOT-353 (SC-88A) package. Each channel provides bidirectional ESD protection with 5.6 V nominal Zener breakdown and sub-40 Ω dynamic impedance at 5 mA test current.
It operates exclusively under transient stress conditions-no DC bias or constant-voltage regulation capability is specified or supported. The 29 pF capacitance is measured at 0 V reverse bias and 1 MHz, ensuring minimal signal distortion on 480 Mbps USB 2.0 differential pairs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage | 5.6 V (typ.), ensures clamping activation before damage to downstream 3.3 V or 5 V logic interfaces |
| Terminal capacitance | 29 pF (typ. at 0 V, 1 MHz), preserves signal integrity on high-speed digital lines up to 480 Mbps |
| ESD immunity | ±30 kV (IEC61000-4-2 contact discharge), exceeds industrial-grade immunity requirements |
| Power dissipation | 100 mW (max.), limits thermal stress during short-duration ESD events |
| Junction temperature | 150 °C (max.), defines upper thermal operating limit for reliability-critical PCB layouts |
| Reverse leakage | ≤1.0 μA at 3.5 V, minimizes standby power loss in battery-powered sensor nodes |
Pinout & Package
Package: SOT-353 (SC-88A), JEDEC-compliant 5-pin ultra-small outline transistor package with 0.65 mm pitch; footprint matches standard SC-88A land pattern (TOSHIBA designation: 1-2W1A).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD clamp anode connection point for Channel 1 signal line |
| 2 | Anode | Common anode node tied to ground plane; all four cathodes reference this terminal |
| 3 | Cathode 2 | ESD clamp anode connection point for Channel 2 signal line |
| 4 | Cathode 3 | ESD clamp anode connection point for Channel 3 signal line |
| 5 | Cathode 4 | ESD clamp anode connection point for Channel 4 signal line |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel integration | Four independent ESD clamps in one 1.6 × 1.6 mm package, reducing PCB area by ~75% vs discrete diodes |
| Low capacitance | 29 pF typical enables use on USB 2.0, HDMI, and MIPI D-PHY interfaces without signal degradation |
| High ESD robustness | ±30 kV contact discharge rating meets IEC61000-4-2 Level 4, eliminating need for secondary protection stages |
| Strict ESD-only function | No DC Zener regulation capability-prevents misuse as voltage reference or regulator in power circuits |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− differential pair in portable USB peripherals against human-body-model ESD events. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point. Use Value: 29 pF capacitance avoids signal rise-time degradation while delivering ±30 kV immunity per line. | Use Scenario: Shielding TMDS clock and data channels in compact HDMI source devices like set-top boxes.

IC Role / Device Role / Timing Role: Four-channel clamping device covering left/right/ground/mic paths in shared ground topology. Use Value: Common-anode architecture enables ground-referenced protection without adding series resistance to audio paths. | Use Scenario: Securing RS-485 or CAN FD transceiver I/O pins in factory-floor automation nodes exposed to charged personnel. IC Role / Device Role / Timing Role: Standoff ESD suppressor mounted at connector, upstream of transceiver IC. Use Value: 5.6 V clamping threshold aligns with 3.3 V transceiver rail tolerance while avoiding false triggering during normal operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 2-channel, 15 pF typical capacitance, ±8 kV IEC61000-4-2 rating | Lower ESD rating; suited for cost-sensitive consumer ports where ±8 kV suffices | Select when lower capacitance is critical and system-level ESD testing confirms ±8 kV adequacy |
| ESD5V3U2U-2/TR | Quad-channel, 35 pF typical capacitance, ±20 kV IEC61000-4-2 rating | Higher capacitance limits use to ≤100 Mbps interfaces; lower ESD margin than DF5A5.6CJE | Choose when board layout constraints require identical pinout but allow relaxed signal bandwidth |
Compared with TPD2E001DRYR and ESD5V3U2U-2/TR, the DF5A5.6CJE delivers the highest ESD immunity (±30 kV) in a quad-channel form factor, making it optimal for ruggedized portable designs where field-replaceable connectors face frequent electrostatic exposure-without sacrificing high-speed signal fidelity.

FAQ
Can DF5A5.6CJE be used as a Zener voltage regulator?
No. The DF5A5.6CJE is explicitly designated for ESD protection only and must not be used as a constant-voltage Zener diode. Its electrical characteristics-including dynamic impedance and reverse leakage-are specified only under transient ESD stress conditions, not steady-state DC regulation. Using DF5A5.6CJE as a voltage reference violates Toshiba's stated restriction and risks premature failure or unpredictable clamping behavior.
What is the maximum signal data rate compatible with DF5A5.6CJE?
The DF5A5.6CJE supports signal integrity up to 480 Mbps, validated by its 29 pF typical terminal capacitance at 1 MHz and low dynamic impedance (<40 Ω). This makes it suitable for USB 2.0 full-speed operation and HDMI 1.4 TMDS clock/data lanes, provided PCB trace lengths remain short and impedance-controlled. Higher-speed protocols like USB 3.0 or HDMI 2.0 require lower-capacitance alternatives.
Is DF5A5.6CJE RoHS compliant?
Yes. DF5A5.6CJE complies with the EU RoHS Directive, containing no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE). RoHS compliance documentation is available from Toshiba upon request, and the device carries appropriate marking per JEITA ED-4701 standard.
How should the common anode (Pin 2) of DF5A5.6CJE be connected?
Pin 2 (Anode) must be connected directly to a low-inductance ground plane-ideally via multiple vias-to ensure effective ESD current shunting. Any series impedance (e.g., ferrite beads or resistors) between Pin 2 and ground degrades clamping performance and may cause voltage overshoot during ESD events. The DF5A5.6CJE relies on this low-impedance path to divert >30 kV transients safely away from protected ICs.
Does DF5A5.6CJE support IEC61000-4-2 air discharge testing?
No. The DF5A5.6CJE's guaranteed ESD immunity level of ±30 kV applies solely to contact discharge per IEC61000-4-2. Air discharge performance is not characterized or warranted by Toshiba. System-level validation for air discharge must be performed separately, and designers should assume lower immunity-typically 2–3× less than contact rating-unless verified by independent testing of the full assembly including DF5A5.6CJE.
