Product details
Overview
DF5A5.6LJE from Toshiba is a quad-channel ESD protection diode array designed for high-speed data lines, featuring 5.6 V nominal zener voltage, 8.0 pF typical terminal capacitance, ±8 kV IEC61000-4-2 contact discharge immunity, and ultra-compact 1-2W1A package. It serves as transient voltage suppression on USB, HDMI, or audio interface signal paths in portable electronics.
For engineers reviewing the DF5A5.6LJE datasheet, DF5A5.6LJE pinout, DF5A5.6LJE application, or DF5A5.6LJE equivalent, key selection criteria include low-capacitance ESD clamping for signal integrity preservation, multi-line integration to reduce board area, and strict compliance with IEC61000-4-2 Level 4 ESD immunity requirements.
Technical Context
This device integrates four independent ESD protection diodes in a single surface-mount package, each configured as a cathode-anode zener clamp with bidirectional breakdown behavior. Its low 8.0 pF capacitance enables use on high-frequency interfaces up to ~500 MHz without significant signal degradation.
The DF5A5.6LJE operates exclusively as an ESD transient suppressor-not as a voltage regulator or constant-voltage reference-per Toshiba's explicit restriction. Its 5.6 V zener voltage (at 5 mA) and ≤50 Ω dynamic impedance ensure fast, low-clamping-voltage response during electrostatic events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage VZ | 5.6 V (typ.) at IZ = 5 mA - defines clamping threshold during ESD transients |
| Terminal capacitance CT | 8.0 pF (typ.) at VR = 0 V, f = 1 MHz - preserves signal integrity on high-speed lines |
| ESD immunity | ±8 kV per IEC61000-4-2 contact discharge - meets industrial and consumer Level 4 requirement |
| Power dissipation P | 100 mW - limits thermal stress during repeated ESD events |
| Junction temperature Tj | 150 °C max - sets upper operating limit for reliability under surge conditions |
| Reverse current IR | ≤1.0 μA at VR = 3.5 V - ensures minimal leakage in standby signal paths |
Pinout & Package
Package: 5-pin SOT-353 (TOSHIBA code 1-2W1A), 1.25 mm × 1.25 mm × 0.9 mm, weight 0.003 g (typ.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD clamp output for Channel 1 signal line |
| 2 | Anode | Common anode connection shared by all four diodes |
| 3 | Cathode 2 | ESD clamp output for Channel 2 signal line |
| 4 | Cathode 3 | ESD clamp output for Channel 3 signal line |
| 5 | Cathode 4 | ESD clamp output for Channel 4 signal line |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel integration | Four independent ESD diodes in one 1.25 mm × 1.25 mm package - reduces PCB footprint and assembly cost vs. discrete solutions |
| Low terminal capacitance | 8.0 pF typical - enables use on USB 2.0, audio codecs, and other >10 MHz signal paths without bandwidth loss |
| IEC61000-4-2 compliance | ±8 kV contact discharge - satisfies highest common ESD immunity level for end-user ports |
| Controlled zener voltage | 5.3–6.0 V range at 5 mA - ensures predictable clamping onset across process variation |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detect |
|---|---|
Use Scenario: Protecting D+ and D− differential pair in smartphone or tablet USB ports against user-handling ESD events. IC Role / Device Role / Timing Role: ESD transient suppressor placed directly at connector, clamping voltage spikes before they reach PHY IC. Use Value: 8.0 pF capacitance avoids signal rise-time degradation; ±8 kV rating prevents latch-up or damage during real-world handling. | Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) line in AV receivers or monitors exposed to frequent cable insertion/removal. IC Role / Device Role / Timing Role: Bidirectional ESD clamp between HPD pin and ground, maintaining DC logic levels while shunting transients. Use Value: 5.6 V zener voltage aligns with HDMI 5 V tolerance margin; quad configuration allows co-location with other interface lines. |
| Smartphone Audio Jack | Industrial Sensor Interface |
Use Scenario: Protecting left/right audio channels and microphone input in 3.5 mm TRRS jacks of mobile handsets. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp on each analog audio path, preserving SNR and frequency response. Use Value: Sub-10 pF capacitance prevents high-frequency attenuation; small size fits tight space near jack mounting. | Use Scenario: Shielding RS-485 or CAN FD transceiver I/O pins in factory automation nodes mounted in ungrounded enclosures. IC Role / Device Role / Timing Role: Standoff ESD protection element placed before transceiver input, limiting voltage seen by sensitive receiver circuitry. Use Value: 100 mW power rating supports multiple moderate-energy discharges; common-anode architecture simplifies PCB routing. |
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 capacitance, 12 kV IEC61000-4-2, same 1.25 mm × 1.25 mm package | Lower capacitance but no multi-line integration - requires four devices for equivalent channel count | Preferred when ultra-low capacitance dominates over part count reduction |
| ESD5Z5.0T1G | Single-channel, 5.0 V VZ, 12 pF CT, SOD-523 package (1.3 mm × 0.85 mm) | Higher capacitance, smaller package width - less suitable for high-speed data but lower profile | Selected where board height is constrained more than signal bandwidth |
Compared with TPD2E001DRYR and ESD5Z5.0T1G, the DF5A5.6LJE uniquely balances multi-line integration, moderate capacitance, and standardized zener voltage-making it optimal for compact, cost-sensitive designs requiring ≥4 protected lines without sacrificing USB 2.0 or audio performance.

FAQ
What is the primary function of the DF5A5.6LJE?
The DF5A5.6LJE is a quad-channel ESD protection diode array designed solely for electrostatic discharge suppression on signal lines. It is not intended for voltage regulation or constant-voltage applications. Each channel features a zener-based clamp with 5.6 V nominal breakdown voltage, and the device complies with IEC61000-4-2 ±8 kV contact discharge testing. The DF5A5.6LJE must be used strictly within its specified ESD-only role per Toshiba's documentation.
Does the DF5A5.6LJE support bidirectional ESD protection?
Yes, the DF5A5.6LJE provides bidirectional ESD protection via its cathode-anode zener configuration per channel. With a common anode (Pin 2) and four independent cathodes (Pins 1, 3, 4, 5), it clamps both positive and negative transients relative to ground. This architecture enables protection of AC-coupled or bidirectional signal lines such as USB D+/D− or HDMI TMDS pairs without polarity constraints. The DF5A5.6LJE achieves this while maintaining 8.0 pF typical capacitance.
Can the DF5A5.6LJE be used on high-speed interfaces like USB 2.0?
Yes, the DF5A5.6LJE is suitable for USB 2.0 data lines due to its 8.0 pF typical terminal capacitance and low dynamic impedance (≤50 Ω). Measured at 1 MHz and zero bias, this capacitance introduces negligible insertion loss below 480 MHz, preserving signal integrity and eye diagram margins. Layout best practices-such as minimizing trace length between connector and DF5A5.6LJE-must still be followed. The DF5A5.6LJE's performance has been validated in USB 2.0 reference designs by Toshiba.
What is the maximum junction temperature rating for the DF5A5.6LJE?
The DF5A5.6LJE has a maximum junction temperature (Tj) rating of 150 °C, as specified in Toshiba's Absolute Maximum Ratings table. This limit applies under continuous operation and must be respected during both normal signal conditions and transient ESD events. Thermal design should account for power dissipation (100 mW max) and ambient conditions. Exceeding 150 °C risks accelerated parametric drift or permanent failure. Derating guidance for the DF5A5.6LJE is provided in the Toshiba Semiconductor Reliability Handbook.
Is the DF5A5.6LJE RoHS compliant?
Yes, the DF5A5.6LJE is RoHS compliant, as confirmed by Toshiba's environmental documentation and material declarations. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE) above regulated thresholds. RoHS status is verified per EU Directive 2011/65/EU and updated through Toshiba's official product change notifications. Customers should consult Toshiba's latest compliance report for the DF5A5.6LJE to confirm substance concentrations and exemptions.
