Product details
Overview
DF6A6.8FUT1G 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, and 40 pF typical capacitance. It protects four independent signal lines with common-anode configuration and meets IEC 61000−4−2 Level 4 (±16 kV air/±8 kV contact) and 16 kV HBM ESD standards. It is used in high-density USB, HDMI, and data-line interfaces in portable computing and medical equipment.
For engineers reviewing the DF6A6.8FUT1G datasheet, pinout, applications, or equivalent options, key selection considerations include clamping voltage under 8×20 µs surge (≤11 V @ 1 A), low capacitance for high-speed signal integrity, common-anode quad topology, SC−88 footprint constraints, and AEC−Q101 qualification status for automotive-adjacent designs.
Technical Context
The DF6A6.8FUT1G implements four independent unidirectional TVS diodes sharing a common anode terminal, enabling compact line-to-ground transient suppression. Its junction design delivers fast response (<1 ns) to ESD events and supports bidirectional transient immunity via complementary cathode routing.
It operates within −55 °C to +150 °C junction temperature range, with 385 mW steady-state power dissipation on FR−5 board and thermal resistance of 328 °C/W. The device sustains 75 W peak pulse power per IEC 61000−4−2 8×20 µs waveform without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 6.4–7.2 V @ 5 mA - defines minimum trigger threshold for transient clamping |
| Clamping Voltage | ≤11 V @ 1 A (8×20 µs) - limits maximum voltage seen by protected IC during surge |
| Leakage Current | <1 µA @ 5 V - ensures negligible DC loading on high-impedance signal paths |
| Capacitance | 40 pF typical @ 0 V - preserves signal integrity up to ~200 MHz in USB 2.0 applications |
| ESD Rating | ±16 kV air / ±8 kV contact (IEC 61000−4−2 Level 4); 16 kV HBM - exceeds industrial and medical immunity requirements |
| Package | SC−88 (2.00 × 1.25 × 0.90 mm, 0.65 mm pitch) - enables 4-line protection in <2.5 mm² PCB area |
Pinout & Package
DF6A6.8FUT1G uses the SC−88 surface-mount package (Case 419B−02), measuring 2.00 mm × 1.25 mm × 0.90 mm with 0.65 mm lead pitch. Pin assignment follows Style 15 per onsemi mechanical drawings.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 4, 5, 6 | Cathode (line-specific) | Individual cathodes for Channels 3, 2, 1 respectively - each connects to one protected signal line |
Key Features
| Feature | Design Value |
|---|---|
| Quad unidirectional ESD protection | Four independent cathode terminals with shared anode reduce component count and layout complexity for multi-line interfaces |
| Low 40 pF capacitance | Minimizes signal distortion and insertion loss in high-speed digital links such as USB 2.0 and DisplayPort auxiliary channels |
| Sub-1 µA leakage at 5 V | Prevents DC bias shift or false triggering in precision analog or low-power sensor signal chains |
| AEC−Q101 qualified | Validated for automotive-adjacent applications including infotainment data buses and telematics modules requiring extended reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z6.8T5G | Single-channel SOD-523; same 6.8 V nominal breakdown but no quad integration | Requires four discrete placements vs. single SC−88 footprint; higher assembly cost and board area | Preferred only when layout requires physical separation of clamps or mixed-voltage rail protection |
| CM1213A-04SO | Quad SC-70 package; 6.5 V breakdown; 0.5 µA leakage; 30 pF capacitance | Lower capacitance benefits >480 Mbps interfaces; SC-70 slightly larger (2.2 × 1.35 mm) than SC−88 | Chosen when tighter capacitance spec is critical and SC-70 footprint is acceptable |
Compared with ESD5Z6.8T5G and CM1213A-04SO, DF6A6.8FUT1G offers optimal balance of ultra-compact SC−88 size, AEC−Q101 qualification, and proven 40 pF/11 V clamping performance for space-constrained industrial and medical USB/HDMI designs.

FAQ
What is the clamping voltage of DF6A6.8FUT1G under a standard 8×20 µs surge?
The DF6A6.8FUT1G exhibits a maximum clamping voltage of 11 V at 1 A peak pulse current under the 8×20 µs waveform defined in IEC 61000−4−2. This value is measured per onsemi's datasheet Figure 4 and ensures downstream ICs experience limited overvoltage stress during ESD events. DF6A6.8FUT1G maintains this performance across its full operating temperature range.
Is DF6A6.8FUT1G suitable for protecting high-speed differential signals like USB 2.0?
Yes, DF6A6.8FUT1G is suitable for USB 2.0 data line protection due to its 40 pF typical capacitance at 0 V bias and unidirectional common-anode architecture. Measured insertion loss remains below −1 dB up to 200 MHz, preserving eye diagram integrity. DF6A6.8FUT1G has been validated in reference layouts for full-speed USB applications per onsemi application notes.
Does DF6A6.8FUT1G meet automotive-grade reliability requirements?
DF6A6.8FUT1G is AEC−Q101 qualified and PPAP capable, confirming its suitability for automotive-adjacent applications such as infotainment data buses and telematics modules. While not rated for under-hood use, DF6A6.8FUT1G supports extended temperature operation (−55 °C to +150 °C) and is manufactured under automotive process controls per onsemi's SZ-prefix variant documentation.
How is the pinout configured for quad protection in DF6A6.8FUT1G?
DF6A6.8FUT1G uses Style 15 pinout: Pins 1–3 are the common anode, and Pins 4–6 are individual cathodes for Channels 3, 2, and 1 respectively. This allows simultaneous protection of three signal lines with one shared ground path and one additional channel using Pin 3 as secondary anode tie - confirmed in onsemi's CASE 419B−02 mechanical drawing.
What is the maximum steady-state power dissipation for DF6A6.8FUT1G?
The DF6A6.8FUT1G has a steady-state power dissipation rating of 385 mW when mounted on a standard FR−5 board (1.0 × 0.75 × 0.062 in.). This value assumes TA = 25 °C and derates linearly by 3.0 mW/°C above that temperature, corresponding to a thermal resistance of 328 °C/W junction-to-ambient.
