Product details
Overview
DF5A5.6JE from TOSHIBA is a quad-channel ESD protection diode array designed for high-density I/O line protection in portable electronics. It features 5.6 V nominal Zener voltage (IZ = 5 mA), ≤40 Ω dynamic impedance, 65 pF typical terminal capacitance at 0 V/1 MHz, and ±30 kV IEC61000-4-2 contact discharge immunity - deployed on USB, HDMI, and SD card interfaces.
For engineers reviewing the DF5A5.6JE datasheet, DF5A5.6JE pinout, DF5A5.6JE application, or DF5A5.6JE equivalent, key selection criteria include low clamping voltage under ESD stress, ultra-low capacitance for high-speed signal integrity, quad-channel integration to reduce board area, and guaranteed ±30 kV ESD robustness without functional degradation.
Technical Context
The DF5A5.6JE integrates four independent Zener-type ESD protection diodes in a single ultra-compact surface-mount package. Each channel operates as a bidirectional clamp between cathode and anode, with a specified Zener voltage range of 5.3–6.0 V at 5 mA test current and guaranteed ESD immunity per IEC61000-4-2 Contact Discharge up to ±30 kV.
Its 65 pF typical capacitance (VR = 0 V, f = 1 MHz) and ≤40 Ω dynamic impedance ensure minimal signal distortion on data lines up to ~100 Mbps. The device is explicitly restricted to ESD-only use - not rated for continuous voltage regulation or surge suppression beyond transient electrostatic events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage | 5.3–6.0 V at IZ = 5 mA - defines clamping threshold during ESD transients |
| Dynamic impedance | ≤40 Ω - ensures low-voltage overshoot during fast ESD pulses |
| Terminal capacitance | 65 pF typical (VR = 0 V, f = 1 MHz) - preserves signal integrity on high-speed interfaces |
| ESD immunity | ±30 kV IEC61000-4-2 contact discharge - validated no-damage performance |
| Power dissipation | 100 mW - limits thermal stress during repetitive ESD events |
| Junction temperature | −55 to +150 °C - supports operation in consumer and industrial ambient environments |
Pinout & Package
DF5A5.6JE uses a 5-pin SOT-353 (1-2W1A) package with exposed pad for thermal relief. Pin 1 is Cathode 1, Pin 2 is Anode (common anode configuration), Pin 3 is Cathode 2, Pin 4 is Cathode 3, and Pin 5 is Cathode 4 - enabling four independent unidirectional clamps sharing one anode node.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD clamp output for Channel 1 signal line |
| 2 | Anode (common) | Shared return path to ground or reference rail |
| 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 ESD protection | Four independent clamps in one 1.6 × 1.6 mm package - reduces component count and PCB footprint by 75% vs. discrete diodes |
| Low clamping voltage | 5.6 V nominal Zener voltage with tight 5.3–6.0 V tolerance - ensures reliable protection of 5 V logic interfaces |
| Ultra-low capacitance | 65 pF typical - enables use on USB 2.0, HDMI DDC, and SDIO lines without signal degradation |
| High ESD robustness | ±30 kV IEC61000-4-2 contact discharge rating - exceeds industrial and consumer immunity requirements |
Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
Use Scenario: Protecting differential USB 2.0 D+ and D− lines against human-body-model ESD events in smartphones and tablets. IC Role / Device Role / Timing Role: Unidirectional ESD clamp per line, with common-anode grounding to system GND. Use Value: 65 pF capacitance avoids signal rise-time degradation; ±30 kV rating prevents latch-up or permanent damage during handling. | Use Scenario: Safeguarding HDMI Display Data Channel (DDC) SDA/SCL lines connecting source and display devices. IC Role / Device Role / Timing Role: Bidirectional transient suppressor on 5 V open-drain I²C bus lines. Use Value: 5.6 V clamping aligns with HDMI 5 V logic levels; quad integration protects both SDA and SCL with shared anode routing. |
| SD Card Interface | Mobile Camera Module Bus |
Use Scenario: Shielding SDIO command, clock, and data lines in compact handheld devices subject to frequent insertion/removal. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp on each signal line referenced to host ground. Use Value: ≤40 Ω dynamic impedance minimizes voltage overshoot during 15 kV air-discharge events; small SOT-353 footprint fits tight board spacing. | Use Scenario: Protecting MIPI CSI-2 clock and data lanes between image sensor and processor in space-constrained camera modules. IC Role / Device Role / Timing Role: High-speed ESD suppressor placed adjacent to connector to divert transients before reaching IC pins. Use Value: 65 pF capacitance maintains >100 Mbps eye diagram integrity; quad layout allows full-lane protection with single-component placement. |
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, 5.5 V clamping, 12 pF capacitance, ±8 kV IEC61000-4-2 | Lower ESD rating and per-channel packaging - requires four devices for equivalent coverage | Preferred where ultra-low capacitance (<15 pF) is critical and board area is less constrained |
| ESD5V3U2U-2/TR | Quad-channel, 5.3 V clamping, 100 pF capacitance, ±20 kV IEC61000-4-2 | Higher capacitance limits use to sub-50 Mbps interfaces; lower ESD rating than DF5A5.6JE | Suitable for cost-sensitive industrial control I/O where speed is secondary to basic ESD compliance |
Compared with TPD2E001DRYR and ESD5V3U2U-2/TR, the DF5A5.6JE delivers superior ESD immunity (±30 kV vs. ±8/±20 kV) and balanced capacitance (65 pF) - making it optimal for high-reliability, high-speed consumer interface protection where single-package quad integration is required.

FAQ
What is the primary function of the DF5A5.6JE?
The DF5A5.6JE is a quad-channel ESD protection diode array designed exclusively for transient electrostatic discharge suppression on signal lines. It is not intended for voltage regulation, surge suppression, or continuous power dissipation. Its 5.6 V Zener voltage and ±30 kV IEC61000-4-2 rating make the DF5A5.6JE suitable only for protecting sensitive I/O interfaces against short-duration ESD events.
Does the DF5A5.6JE support bidirectional or unidirectional ESD clamping?
The DF5A5.6JE implements unidirectional clamping per channel, with a common anode (Pin 2) and four dedicated cathodes (Pins 1, 3, 4, 5). When used with the anode tied to ground, it clamps positive transients toward GND. For bidirectional protection, external series resistors or complementary diode configurations are required - the DF5A5.6JE itself does not provide intrinsic bidirectional behavior.
What is the significance of the 65 pF terminal capacitance specification for the DF5A5.6JE?
The 65 pF typical terminal capacitance (measured at VR = 0 V, f = 1 MHz) directly impacts high-speed signal integrity. This value allows the DF5A5.6JE to be safely deployed on USB 2.0, HDMI DDC, and SDIO interfaces without degrading edge rates or causing bit errors. Capacitance above ~100 pF would risk signal distortion on these buses, making the DF5A5.6JE's 65 pF a key enabler for its target applications.
Can the DF5A5.6JE be used for overvoltage protection beyond ESD events?
No - the DF5A5.6JE is explicitly restricted to ESD-only use per Toshiba's documentation. It is not rated for sustained overvoltage, lightning-induced surges, or repetitive switching transients. Continuous operation above its 100 mW power dissipation limit or outside its −55 to +150 °C junction temperature range may cause irreversible degradation. The DF5A5.6JE must never be substituted for TVS diodes rated for higher-energy threats.
What package type and dimensions does the DF5A5.6JE use?
The DF5A5.6JE uses the SOT-353 (TOSHIBA designation: 1-2W1A) package, measuring 1.6 mm × 1.6 mm × 0.55 mm with a 0.65 mm pin pitch. This ultra-compact 5-pin outline accommodates four ESD channels in minimal PCB area, and its exposed pad enhances thermal dissipation during ESD pulse absorption. The package weight is 0.003 g (typical), confirming suitability for lightweight portable assemblies.
