Product details
Overview
DF6A6.8FUT2G from onsemi is a quad unidirectional ESD protection diode array in SC−88 package, featuring 6.4–7.2 V breakdown voltage at 5 mA, <1 µA leakage at 5 V, 40 pF typical capacitance, and IEC 61000−4−2 Level 4 (±16 kV air/±8 kV contact) ESD rating - deployed for high-density USB, HDMI, and data-line protection in portable electronics.
For engineers reviewing the DF6A6.8FUT2G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under 12 V at 10 A peak pulse, common-anode quad configuration, low-leakage transient suppression, and Pb-free SC−88 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements four independent unidirectional TVS diodes sharing a common anode terminal, enabling compact line-to-ground ESD clamping without external biasing. Its junction design delivers fast response (<1 ns) to transients while maintaining low dynamic impedance (30 Ω max at 5 mA) and stable clamping performance up to 75 W peak power (8 × 20 µs waveform).
The SC−88 package supports surface-mount assembly with 0.65 mm pitch and thermal resistance of 328 °C/W (junction-to-ambient), allowing reliable operation from −55 °C to +150 °C. It meets AEC−Q101 stress testing requirements and is qualified for automotive and industrial environments where robustness against electrostatic discharge is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 6.4–7.2 V @ 5 mA - defines minimum trigger threshold for ESD clamping activation |
| Clamping Voltage | ≤12 V @ 10 A peak pulse - limits maximum voltage seen by protected IC during surge |
| Leakage Current | <1 µA @ 5 V - ensures negligible standby power loss and signal integrity in high-impedance lines |
| Capacitance | 40 pF typical @ 0 V - enables use on high-speed interfaces like USB 2.0 without signal distortion |
| ESD Rating | ±16 kV air / ±8 kV contact per IEC 61000−4−2 Level 4 - exceeds industrial immunity requirements |
| Peak Pulse Power | 75 W @ 8 × 20 µs - sustains multiple ESD events without degradation |
| Operating Temp | −55 °C to +150 °C - supports deployment in under-hood automotive and medical equipment |

Applications
| USB 2.0 Interface Protection | HDMI Data Lane Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines in portable USB peripherals against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Unidirectional TVS array clamping transient overvoltage before it reaches the USB transceiver IC. Use Value: Prevents latch-up or permanent damage to USB PHY while maintaining <1 ns response and minimal signal attenuation. | Use Scenario: Safeguarding TMDS clock and data channels in compact HDMI source devices such as set-top boxes and docking stations. IC Role / Device Role / Timing Role: Low-capacitance ESD suppressor placed directly at HDMI connector to shunt ESD energy to chassis ground. Use Value: Enables full compliance with IEC 61000−4−2 Level 4 without degrading 2.25 Gbps differential signaling integrity. |
| Medical Sensor Port Protection | Industrial CAN FD Transceiver Interface |
Use Scenario: Shielding analog sensor inputs (e.g., ECG leads, temperature probes) connected to handheld diagnostic tools from handling-induced ESD. IC Role / Device Role / Timing Role: Ground-referenced transient suppressor limiting voltage excursion to <12 V during 15 kV contact discharge. Use Value: Maintains microvolt-level signal fidelity and avoids false triggering of ADC input stages due to low leakage and stable clamping. | Use Scenario: Adding secondary ESD protection on CAN FD bus lines (CANH/CANL) in motor control modules where primary transceiver ESD margin is insufficient. IC Role / Device Role / Timing Role: Standoff diode array absorbing fast-rising transients before they reach the CAN FD controller's physical layer. Use Value: Extends system-level ESD immunity beyond ISO 10605 requirements while preserving 5 Mbps bit timing accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | Lower capacitance (0.5 pF), higher VBR (6.5–7.5 V), same SC−88 package | Better suited for >5 Gbps interfaces (e.g., USB 3.2 Gen 1); less effective for high-energy surges | Select when ultra-low capacitance is prioritized over peak power handling |
| SZ1.5SMC6.8AT3G | Higher power rating (1500 W), DO-214AB package, unidirectional, single-channel | Used for board-level primary protection; not suitable for multi-line density constraints | Choose for standalone high-energy surge suppression where space permits discrete placement |
Compared with TPD4E05U06DQAR and SZ1.5SMC6.8AT3G, DF6A6.8FUT2G uniquely balances quad-line integration, 40 pF capacitance, and 75 W pulse capability in a 2.0 × 1.25 mm footprint - making it optimal for space-limited, multi-signal ESD hardening where moderate speed and robustness are both required.

FAQ
What is the exact pin configuration of DF6A6.8FUT2G?
The DF6A6.8FUT2G uses Style 15 pinout per onsemi's SC−88 mechanical documentation: Pin 1 = Anode 1, Pin 2 = Anode 2, Pin 3 = Anode 3, Pin 4 = Cathode 3, Pin 5 = Cathode 2, Pin 6 = Cathode 1. This common-anode quad arrangement allows independent cathode connections to four protected lines while sharing a grounded or biased anode network - confirmed in the official datasheet revision 4 (June 2024).
Does DF6A6.8FUT2G meet automotive qualification standards?
Yes, DF6A6.8FUT2G is AEC−Q101 qualified and PPAP capable, with test evidence covering temperature cycling, humidity bias, ESD, and mechanical shock. The "SZ" prefix variant (e.g., SZDF6A6.8FUT1G) explicitly denotes automotive-grade screening, but DF6A6.8FUT2G shares identical die and construction - making it suitable for automotive infotainment, body control, and ADAS subsystems operating from −40 °C to +125 °C ambient.
What is the clamping voltage of DF6A6.8FUT2G at 10 A peak current?
Per the onsemi datasheet Figure 4, DF6A6.8FUT2G exhibits a maximum clamping voltage of 12 V at 10 A peak pulse (8 × 20 µs waveform). This value ensures downstream ICs - such as USB transceivers or HDMI serializers - remain within absolute maximum ratings during ESD events, and is measured with the device mounted on standard FR-5 board per JEDEC JESD22-A114 test conditions.
Can DF6A6.8FUT2G be used for bidirectional signal lines?
No, DF6A6.8FUT2G is strictly unidirectional - each channel conducts only from cathode to anode. It is unsuitable for AC-coupled or bidirectional buses (e.g., I²C, RS-485) without external biasing. For bidirectional protection, engineers must select dedicated symmetric TVS arrays like NUP4201MR6T1G or use back-to-back diode configurations - DF6A6.8FUT2G's electrical characteristics and pinout confirm its unidirectional architecture.
Is DF6A6.8FUT2G RoHS and REACH compliant?
Yes, DF6A6.8FUT2G is Pb-free and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The "G" suffix denotes lead-free packaging, and onsemi confirms compliance via material declarations and third-party lab testing - documented in the manufacturer's environmental compliance portal and product change notices dated April 2024.
