Product details
Overview
DF5A5.6FUTE85LF 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, 65 pF typical terminal capacitance at 0 V and 1 MHz, and a 200 mW power dissipation rating. It is used on USB, HDMI, and SD card interfaces to suppress transient electrostatic events.
For engineers reviewing the DF5A5.6FUTE85LF datasheet, DF5A5.6FUTE85LF pinout, DF5A5.6FUTE85LF application, or DF5A5.6FUTE85LF equivalent, key selection criteria include ESD immunity level, channel count per package, junction capacitance impact on signal integrity, and compatibility with high-speed digital interfaces requiring low parasitic loading.
Technical Context
This device implements four independent Zener-clamp diodes in a single ultra-compact surface-mount package, each configured as a cathode-anode-cathode structure (common-anode topology). Each channel provides bidirectional clamping with a 5.6 V nominal breakdown voltage and guarantees no functional damage up to ±30 kV contact discharge per IEC61000-4-2.
The 65 pF typical capacitance between cathode and anode at 0 V bias enables use on data lines up to ~100 Mbps without significant signal degradation, while the 40 Ω max dynamic impedance ensures fast transient response and low clamping voltage overshoot during ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage | 5.6 V nominal at 5 mA; defines clamping threshold for ESD transients on protected lines |
| ESD immunity | ±30 kV contact discharge per IEC61000-4-2; validated robustness against human-body-model-like discharges |
| Terminal capacitance | 65 pF typical at 0 V, 1 MHz; limits insertion loss and timing skew on high-speed digital signals |
| Dynamic impedance | 40 Ω maximum at 5 mA; determines voltage overshoot during fast-rising ESD pulses |
| Power dissipation | 200 mW maximum; sets thermal limit for sustained surge energy absorption |
| Reverse current | 1.0 μA maximum at 2.5 V reverse bias; ensures minimal leakage in standby interface states |
Pinout & Package
DF5A5.6FUTE85LF uses the TOSHIBA 1-2V1B package - a 5-pin SOT-353 (SC-88A) variant with 0.65 mm pitch, measuring 2.0 × 1.25 × 0.9 mm (L×W×H), and weighing 0.0062 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Clamps positive transients on Channel 1 signal line to common anode |
| 2 | Anode | Common anode node shared by all four channels; connects to VCC or ground depending on bias configuration |
| 3 | Cathode 2 | Clamps positive transients on Channel 2 signal line to common anode |
| 4 | Cathode 3 | Clamps positive transients on Channel 3 signal line to common anode |
| 5 | Cathode 4 | Clamps positive transients on Channel 4 signal line to common anode |
Key Features
| Feature | Design Value |

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 typical capacitance, 12 kV IEC61000-4-2 rating | Targeted at ultra-high-speed interfaces (e.g., USB 3.0, PCIe); lower capacitance but reduced ESD margin | Choose when signal bandwidth >1 GHz is required and ±30 kV is not mandated |
| ESD5Z5.0T1G | Single-channel, 5.0 V nominal Zener, 100 pF typical capacitance, ±22 kV IEC61000-4-2 | Higher capacitance limits use to sub-50 Mbps lines; lower ESD rating suits cost-sensitive consumer designs | Prefer for legacy UART/SPI protection where board space is less constrained and ESD threat level is moderate |
Compared with TPD2E001DRYR and ESD5Z5.0T1G, DF5A5.6FUTE85LF uniquely delivers quad-channel integration with ±30 kV immunity and 65 pF capacitance-making it optimal for space-constrained, high-reliability USB/HDMI/SD applications where multi-line coordination and robustness are prioritized over ultra-low capacitance.

FAQ
What is the primary function of DF5A5.6FUTE85LF?
DF5A5.6FUTE85LF is a quad-channel ESD protection diode array designed exclusively for electrostatic discharge suppression on high-speed digital I/O lines. It is not rated for constant-voltage regulation or general-purpose rectification. Its 5.6 V Zener voltage, ±30 kV IEC61000-4-2 immunity, and 65 pF capacitance make DF5A5.6FUTE85LF suitable for protecting USB, HDMI, and SD interfaces without degrading signal integrity.
Does DF5A5.6FUTE85LF support bidirectional ESD protection?
Yes, DF5A5.6FUTE85LF supports bidirectional clamping via its common-anode configuration: each cathode pin clamps positive transients to the shared anode, and reverse-biased conduction protects against negative transients relative to the anode potential. This architecture allows DF5A5.6FUTE85LF to suppress both polarities of ESD events on data lines referenced to VCC or ground.
What is the recommended PCB layout practice for DF5A5.6FUTE85LF?
Place DF5A5.6FUTE85LF within 3 mm of the protected connector, route protected traces directly to cathode pins with minimal stub length, and connect the anode pin to a low-inductance reference plane (VCC or ground) using a dedicated via. Avoid routing other signals near DF5A5.6FUTE85LF's pins to prevent coupling. These practices ensure DF5A5.6FUTE85LF delivers specified ±30 kV immunity without compromising its 65 pF capacitance advantage.
Is DF5A5.6FUTE85LF RoHS compliant and lead-free?
Yes, DF5A5.6FUTE85LF is RoHS compliant and lead-free, meeting EU Directive 2011/65/EU requirements. Toshiba confirms halogen-free status and specifies JEDEC-standard reflow profiles compatible with Pb-free soldering. Full material declarations and test reports for DF5A5.6FUTE85LF are available through authorized Toshiba distributors upon request.
Can DF5A5.6FUTE85LF be used in automotive applications?
No, DF5A5.6FUTE85LF is not qualified for automotive use. Toshiba explicitly restricts this device to consumer and industrial portable electronics, excluding applications requiring AEC-Q200 qualification or operation in safety-critical systems. For automotive infotainment or ADAS interfaces, engineers must select AEC-Q200-qualified alternatives; DF5A5.6FUTE85LF does not meet temperature cycling, vibration, or failure-rate requirements for automotive deployment.
