Product details
Overview
DF5A5.6FTE85LF 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, ±30 kV IEC61000-4-2 contact discharge immunity, and 65 pF typical terminal capacitance at 0 V/1 MHz - enabling robust electrostatic discharge suppression on USB, HDMI, and audio interfaces without signal integrity degradation.
For engineers reviewing the DF5A5.6FTE85LF datasheet, DF5A5.6FTE85LF pinout, DF5A5.6FTE85LF application, or DF5A5.6FTE85LF equivalent, key selection criteria include guaranteed ±30 kV ESD immunity, low 65 pF capacitance for high-speed data lines, quad-cathode configuration with shared anode, 200 mW power dissipation rating, and JEITA package code 1-3H1A surface-mount footprint.
Technical Context
This device implements four independent Zener-clamp diodes in a single ultra-compact SOT-353 (SC-88A) package, with Cathode 1–4 connected to separate I/O lines and Anode tied to common ground. Each channel clamps transient voltages above 5.6 V while maintaining sub-1 μA reverse leakage at 2.5 V.
The design targets low-capacitance ESD protection for differential and single-ended high-speed interfaces. Its 65 pF capacitance is measured between cathode and anode at 0 V bias and 1 MHz, ensuring minimal loading on 480 Mbps USB 2.0 or 1.5 Gbps HDMI signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage | 5.6 V nominal at 5 mA - defines precise clamping threshold for overvoltage transients |
| ESD immunity | ±30 kV per IEC61000-4-2 contact discharge - exceeds industrial and consumer immunity requirements |
| Terminal capacitance | 65 pF typical at 0 V/1 MHz - enables use on USB 2.0, HDMI, and audio data lines without signal distortion |
| Power dissipation | 200 mW - supports repeated ESD events without thermal runaway under standard PCB layout |
| Junction temperature | 125 °C max - sets upper thermal limit for sustained operation in compact handheld enclosures |
| Reverse current | ≤1.0 μA at 2.5 V - ensures negligible standby power loss and signal leakage on protected lines |
Pinout & Package
DF5A5.6FTE85LF uses the JEITA-standardized 1-3H1A package - identical to SOT-353 (SC-88A), measuring 2.1 × 1.25 × 0.9 mm with gull-wing leads. This 5-pin surface-mount package integrates four cathodes and one shared anode in a space-saving configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD clamp output for first protected I/O line (e.g., USB D+) |
| 2 | Anode | Common ground return path for all four clamping diodes |
| 3 | Cathode 2 | ESD clamp output for second protected I/O line (e.g., USB D−) |
| 4 | Cathode 3 | ESD clamp output for third protected I/O line (e.g., HDMI HPD) |
| 5 | Cathode 4 | ESD clamp output for fourth protected I/O line (e.g., audio MIC_IN) |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel ESD protection | Four independent 5.6 V Zener clamps in one 2.1 × 1.25 mm package - reduces board area vs. discrete diodes |
| Ultra-low capacitance | 65 pF typical between cathode and anode - preserves signal integrity on 480 Mbps USB 2.0 links |
| High ESD immunity | ±30 kV contact discharge per IEC61000-4-2 - exceeds Level 4 immunity for consumer and industrial ports |
| Low leakage current | ≤1.0 μA at 2.5 V reverse bias - avoids DC loading on sensitive analog or digital inputs |
Applications
| USB 2.0 Interface Protection | HDMI Port ESD Suppression |
|---|---|
Use Scenario: Protecting differential D+/D− lines of USB 2.0 ports in smartphones and tablets against human-body-model ESD events. IC Role / Device Role / Timing Role: Quad Zener-clamp diode array providing bidirectional transient voltage suppression on two differential pairs. Use Value: 65 pF capacitance prevents signal rise-time degradation, enabling full 480 Mbps data rate compliance while surviving ±30 kV contact discharges. | Use Scenario: Shielding HDMI hot-plug detect (HPD), clock (TMDS CLK), and data channels (TMDS DATA0–2) in set-top boxes and monitors. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp for high-speed TMDS signaling paths operating up to 1.65 Gbps. Use Value: Sub-70 pF inter-electrode capacitance avoids eye-diagram closure and jitter accumulation in 1080p video transmission. |
| Audio Jack ESD Protection | Industrial Sensor Interface Guarding |
Use Scenario: Safeguarding 3.5 mm audio jack microphone and headset lines in portable audio devices from pocket-static discharge. IC Role / Device Role / Timing Role: Four-channel unidirectional Zener clamp isolating mic bias, left/right audio, and ground-sense lines. Use Value: 5.6 V clamping threshold aligns with typical audio codec rail voltages, preventing latch-up while allowing normal AC signal swing. | Use Scenario: Protecting RS-485 transceiver I/O pins and analog sensor inputs (e.g., thermistor, RTD) in factory automation modules. IC Role / Device Role / Timing Role: ESD transient suppressor placed directly at connector entry points before signal conditioning circuitry. Use Value: 200 mW power rating sustains multiple 8 kV air-discharge events per IEC61000-4-2 without parameter shift or failure. |
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 NUP4201MR6T1G | Single-channel dual-diode (bidirectional) configuration; 15 pF capacitance; 12 kV IEC61000-4-2 rating | Lower capacitance but lower ESD rating; requires four devices for quad-line coverage | Prefer when ultra-low capacitance (<20 pF) is critical and ±12 kV suffices |
| Vishay VEML6030X01 | Not applicable - optical ambient light sensor, not an ESD protector | N/A - functionally incompatible | Excluded from viable alternatives due to mismatched device class and function |
Compared with NUP4201MR6T1G, DF5A5.6FTE85LF delivers 2.5× higher ESD immunity (±30 kV vs. ±12 kV) in a single quad-channel package, reducing component count and PCB area - critical for space-constrained mobile designs where robustness outweighs marginal capacitance reduction.

FAQ
What is the primary function of the DF5A5.6FTE85LF?
The DF5A5.6FTE85LF is a quad-channel Zener-type ESD protection diode array designed exclusively for electrostatic discharge suppression on high-speed data and analog I/O lines. It is not rated for constant-voltage regulation or general-purpose rectification. Each channel clamps transients above 5.6 V while maintaining ≤1.0 μA reverse leakage at 2.5 V, and it is certified to ±30 kV IEC61000-4-2 contact discharge.
Does the DF5A5.6FTE85LF support bidirectional ESD protection?
No - the DF5A5.6FTE85LF implements unidirectional Zener clamping, with Cathodes 1–4 connected to protected lines and Anode tied to system ground. It protects against positive transients only. For bidirectional protection, external series resistors or complementary diode configurations are required. The device's specification sheet explicitly states it is intended "for protection against electrostatic discharge only" and prohibits use as a constant-voltage diode.
What package type does the DF5A5.6FTE85LF use, and what are its dimensions?
The DF5A5.6FTE85LF uses the JEITA-standardized 1-3H1A package, equivalent to SOT-353 (SC-88A), with overall dimensions of 2.1 mm × 1.25 mm × 0.9 mm. It features gull-wing surface-mount leads and weighs 0.014 g (typical). The package marking "5.6" identifies the nominal Zener voltage, and pin 1 is Cathode 1, verified by Toshiba's top-view equivalent circuit diagram.
Can the DF5A5.6FTE85LF be used on USB 3.0 or PCIe lanes?
No - the DF5A5.6FTE85LF is not suitable for USB 3.0 SuperSpeed (5 Gbps) or PCIe Gen1+ lanes. Its 65 pF terminal capacitance introduces excessive signal attenuation and jitter at >1 GHz frequencies. It is validated for USB 2.0 (480 Mbps), HDMI 1.4 (1.65 Gbps), and audio interfaces where bandwidth demands remain below 200 MHz. Higher-speed protocols require sub-0.5 pF protection solutions such as TVS arrays with integrated RF matching.
Is the DF5A5.6FTE85LF RoHS compliant and lead-free?
Yes - the DF5A5.6FTE85LF is RoHS compliant and lead-free, as confirmed by Toshiba's environmental documentation and product change notices dated through April 2026. It meets EU Directive 2011/65/EU requirements and contains no intentionally added lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE. Full material declarations and test reports are available upon request from Toshiba or authorized distributors.
