Product details
Overview
DF5A5.6CFUTE85LF 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 1-2V1B package. It serves as transient voltage suppression on USB, HDMI, or audio interface signal paths in portable electronics.
For engineers reviewing the DF5A5.6CFUTE85LF datasheet, DF5A5.6CFUTE85LF pinout, DF5A5.6CFUTE85LF application, or DF5A5.6CFUTE85LF equivalent, key selection criteria include low-capacitance ESD clamping performance, multi-line integration capability, zener voltage tolerance (±0.4 V), junction temperature limit (150°C), and compliance with IEC61000-4-2 Level 4.
Technical Context
This device implements four independent Zener-based ESD clamps in a single monolithic silicon die, each with cathode-anode configuration optimized for bidirectional transient suppression. Its low 29 pF capacitance enables use on signals up to 500 Mbps without signal integrity degradation.
The DF5A5.6CFUTE85LF operates exclusively as an ESD protection element-not as a voltage regulator-per Toshiba's explicit restriction. Its ±30 kV IEC61000-4-2 rating applies only under contact discharge test conditions with no functional damage observed.
Key Specifications

|---|---|
| Zener voltage | 5.6 V (nominal, at 5 mA; ±0.4 V tolerance ensures reliable clamping above logic-high thresholds) |
| Terminal capacitance | 29 pF (typ., at 0 V, 1 MHz; enables use on USB 2.0 and audio differential pairs) |
| ESD immunity | ±30 kV (IEC61000-4-2 contact discharge; meets highest industrial ESD robustness class) |
| Power dissipation | 200 mW (max; defines safe single-pulse energy handling per channel) |
| Junction temperature | 150 °C (max operating limit; constrains thermal design in sealed enclosures) |
| Reverse current | 1.0 μA (max at 3.5 V; ensures minimal leakage in battery-powered standby modes) |
Pinout & Package
Package: 1-2V1B - ultra-compact surface-mount package (2.0 × 1.25 × 0.7 mm) with five terminals, optimized for space-constrained mobile PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD clamp anode connection for Channel 1; ties to protected signal line |
| 2 | Anode | Common anode node shared by all four Zener diodes; connects to ground or low-impedance return path |
| 3 | Cathode 2 | ESD clamp anode connection for Channel 2; isolates second signal line |
| 4 | Cathode 3 | ESD clamp anode connection for Channel 3; supports triple-line protection in one footprint |
| 5 | Cathode 4 | ESD clamp anode connection for Channel 4; enables full quad-line protection without discrete parts |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel integration | Four independent ESD clamps in one 1-2V1B package reduces component count and PCB area by 75% vs. discrete diodes |
| Bidirectional clamping | Each channel uses back-to-back Zener structure enabling symmetric ±30 kV ESD suppression without polarity constraints |
| Low capacitance | 29 pF typical ensures <1% signal rise-time degradation on 480 Mbps USB 2.0 lines |
| High ESD robustness | ±30 kV contact discharge rating exceeds IEC61000-4-2 Level 4, eliminating need for secondary protection stages |
Applications
| USB 2.0 Interface Protection | HDMI DDC/CEC Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− data lines in smartphone USB ports against user-handling ESD events. IC Role / Device Role / Timing Role: Transient voltage suppressor placed directly at connector, clamping fast-rising ESD pulses before they reach PHY IC. Use Value: 29 pF capacitance avoids signal distortion while ±30 kV immunity prevents latch-up or permanent failure during plug/unplug cycles. | Use Scenario: Safeguarding HDMI DDC (I²C) and CEC control lines in TV mainboards exposed to field ESD. IC Role / Device Role / Timing Role: Low-leakage (≤1.0 μA) bidirectional clamp preserving I²C bus timing and pull-up functionality. Use Value: 5.6 V zener threshold sits safely above 3.3 V logic high while clamping transients below IC absolute maximum ratings. |
| Smartphone Audio Jack Protection | Automotive Infotainment USB Port |
Use Scenario: Shielding stereo headphone and mic lines in compact mobile handsets from electrostatic discharge via 3.5 mm jack. IC Role / Device Role / Timing Role: Quad-channel layout matches TRRS pinout (Tip-Ring-Ring-Sleeve), assigning one cathode per signal line. Use Value: Ultra-small 1-2V1B footprint fits within 2.0 mm × 1.25 mm board area, critical for thin bezel designs. | Use Scenario: Hardening USB host ports in automotive head units against ESD in dry cabin environments. IC Role / Device Role / Timing Role: ESD protector mounted adjacent to USB receptacle, leveraging 150 °C junction rating for under-dash thermal resilience. Use Value: 200 mW power dissipation handles multiple sequential ESD strikes without thermal runaway in non-ventilated enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DRYR | Single-channel, 0.5 pF lower capacitance (28.5 pF), same 5.6 V VZ, but rated only to ±15 kV IEC61000-4-2 | Requires four separate placements; less suitable for tight pitch or high-density routing | Select when ultra-low capacitance is prioritized over integration and ESD margin |
| ESD5V3U4-2/TR | Quad-channel like DF5A5.6CFUTE85LF, but higher 35 pF capacitance and ±20 kV rating; uses SOT-363 package (larger footprint) | Compatible pinout but larger 2.2 × 1.35 mm body; may require PCB redesign | Select when existing layout accommodates SOT-363 and cost is primary constraint |
Compared with TPD4E001DRYR and ESD5V3U4-2/TR, the DF5A5.6CFUTE85LF delivers the highest ESD immunity (±30 kV) in the smallest footprint (1-2V1B), making it optimal for next-generation portable devices where space and robustness are co-constrained.

FAQ
What is the exact zener voltage tolerance of DF5A5.6CFUTE85LF?
The DF5A5.6CFUTE85LF has a zener voltage range of 5.3 V to 6.0 V at 5 mA test current, yielding a ±0.4 V deviation from its 5.6 V nominal value. This tolerance ensures consistent clamping behavior across production lots while remaining compatible with 3.3 V and 5 V logic families. The DF5A5.6CFUTE85LF datasheet specifies this range under Electrical Characteristics, confirming its suitability for precise overvoltage thresholding in sensitive interfaces.
Can DF5A5.6CFUTE85LF be used as a voltage regulator?
No, DF5A5.6CFUTE85LF is explicitly designated by Toshiba for ESD protection only and must not be used as a constant-voltage diode or regulator. Its electrical characteristics-including dynamic impedance up to 40 Ω and lack of regulation curve stability-are optimized for transient suppression, not steady-state voltage control. Using DF5A5.6CFUTE85LF outside its specified ESD-only role violates Toshiba's RESTRICTIONS ON PRODUCT USE and risks premature failure.
What is the thermal limit for continuous operation of DF5A5.6CFUTE85LF?
The DF5A5.6CFUTE85LF has a maximum junction temperature of 150 °C and a storage temperature range of −55 °C to +150 °C. Continuous operation must remain within these limits; derating is required above 25 °C ambient per Toshiba's Reliability Handbook. The DF5A5.6CFUTE85LF's 200 mW power dissipation rating assumes adequate PCB copper area for heat spreading, especially in sealed or high-temperature environments.
How does the 29 pF terminal capacitance of DF5A5.6CFUTE85LF affect high-speed signal integrity?
The 29 pF typical terminal capacitance of DF5A5.6CFUTE85LF introduces negligible loading on signals up to 480 Mbps (USB 2.0 full-speed), causing less than 1% rise-time degradation when placed with short traces. This capacitance is measured between cathode and anode at 0 V bias and 1 MHz, reflecting real-world coupling behavior. For DF5A5.6CFUTE85LF, this value enables direct placement on differential pairs without equalization or re-timing.
Is DF5A5.6CFUTE85LF compliant with RoHS and REACH regulations?
Yes, DF5A5.6CFUTE85LF complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed by Toshiba's environmental documentation. Lead-free soldering compatibility is supported up to JEDEC J-STD-020 moisture sensitivity level 1. Customers must verify latest compliance status via Toshiba's official environmental reports, as DF5A5.6CFUTE85LF's RoHS status is subject to ongoing material composition audits.
