Product details
Overview
NNCD6.8PL-T2-A from NEC Electronics is a quad-channel ESD noise clipping diode in a 5-pin Super Small Mini Mold (flat lead) package, featuring 6.2–7.1 V breakdown voltage, ≤90 pF capacitance at 0 V, ≤2 µA reverse leakage at 3.5 V, 30 kV IEC61000-4-2 contact discharge endurance, and 200 mW total power dissipation - deployed for USB, HDMI, and audio jack interface protection.
For engineers reviewing the NNCD6.8PL-T2-A datasheet, NNCD6.8PL-T2-A pinout, NNCD6.8PL-T2-A application, or NNCD6.8PL-T2-A equivalent, key selection criteria include common-anode quad configuration, low 90 pF junction capacitance, guaranteed 30 kV ESD robustness, thermal impedance profile under transient surge, and compatibility with automated SMT placement on high-density PCBs.
Technical Context
This device implements four identical silicon PN-junction clamping diodes sharing a single anode terminal (common-anode quad), enabling simultaneous bidirectional ESD suppression across four signal lines. Each cathode-anode path exhibits tightly specified 6.2–7.1 V breakdown with ≤2 µA leakage at 3.5 V reverse bias.
Designed specifically to meet IEC61000-4-2 Level 4 (30 kV contact), it delivers non-repetitive surge handling up to 85 W (10 µs pulse) while maintaining ≤90 pF capacitance at 0 V - critical for preserving signal integrity in high-speed interfaces like USB 2.0 and analog audio paths.

Applications
| USB Interface Protection | HDMI Connector Protection |
|---|---|
Use Scenario: Protecting USB 2.0 data lines (D+, D−) and VBUS/ID pins against user-handling ESD events during cable insertion. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamping diode array absorbing ±30 kV contact discharges before they reach the USB transceiver. Use Value: Prevents latch-up or permanent damage to USB PHY ICs while maintaining <100 ps signal delay due to 90 pF capacitance. | Use Scenario: Shielding HDMI Type-A connector pins (TMDS clock/data pairs, CEC, HPD) from electrostatic discharge during hot-plug operations. IC Role / Device Role / Timing Role: Quad-channel ESD suppressor with common anode referenced to chassis ground, clamping transients on four high-speed differential lanes. Use Value: Ensures HDMI compliance by limiting post-clamp overshoot to <10% of signal swing, verified under IEC61000-4-2 test conditions. |
| Audio Jack ESD Suppression | Industrial Sensor Interface Protection |
Use Scenario: Safeguarding 3.5 mm TRRS audio jacks (tip, ring1, ring2, sleeve) in smartphones and headsets from human-body-model ESD. IC Role / Device Role / Timing Role: Four independent cathodes routed to each contact, with shared anode connected to clean analog ground plane. Use Value: Eliminates audible pop/crackle during plug insertion by clamping transients below 7.1 V before reaching codec inputs. | Use Scenario: Protecting 4–20 mA current-loop sensor inputs and digital status lines in factory automation I/O modules exposed to maintenance personnel ESD. IC Role / Device Role / Timing Role: Discrete-level ESD clamp placed directly at connector entry point, shunting energy to system ground before entering signal conditioning circuitry. Use Value: Maintains sensor accuracy by preventing input-stage overvoltage that would otherwise cause offset drift or ADC saturation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DBVR | Lower 0.5 pF typical capacitance; 12 kV IEC61000-4-2 rating; 6-pin SOT-563 package | Better suited for >5 Gbps interfaces (e.g., USB3.2 Gen2); lower ESD rating limits use in harsh industrial settings | Select when ultra-low capacitance is prioritized over ESD margin and board space allows 6-pin layout |
| ESD5Z6.8T1G | Single-channel, same 6.8 V nominal breakdown; 100 pF max capacitance; SOD-523 package | Requires four discrete placements; higher total footprint and solder joint count vs. integrated quad | Choose only if existing design uses single-diode footprints and cannot accommodate 5-pin common-anode layout |
Compared with TPD4E05U06DBVR and ESD5Z6.8T1G, the NNCD6.8PL-T2-A provides superior 30 kV ESD immunity in a space-optimized quad configuration - making it preferred for cost-sensitive, high-volume industrial and consumer interfaces where robustness and assembly efficiency are critical.

FAQ
What is the exact pin configuration of the NNCD6.8PL-T2-A?
The NNCD6.8PL-T2-A uses a 5-pin flat-lead package with pins assigned as follows: Pin 1 = K1, Pin 2 = A (common anode), Pin 3 = K2, Pin 4 = K3, Pin 5 = K4. This common-anode quad structure allows all four cathodes to clamp independently to the shared anode node, which must be connected to a low-impedance ground reference. The NNCD6.8PL-T2-A datasheet confirms this electrode connection on page 2.
Does the NNCD6.8PL-T2-A meet IEC61000-4-2 Level 4 ESD requirements?
Yes, the NNCD6.8PL-T2-A is rated for ≥30 kV contact discharge per IEC61000-4-2, exceeding Level 4 (8 kV contact / 15 kV air) requirements. This rating is validated in the official datasheet (D15989EJ1V0DS00, page 2) and applies to all four channels simultaneously. The NNCD6.8PL-T2-A achieves this through optimized junction design and thermal layout within its 5-pin mini mold package.
What is the maximum allowable reverse voltage for continuous operation of the NNCD6.8PL-T2-A?
The NNCD6.8PL-T2-A has no specified DC reverse standoff voltage; its function is transient clamping, not steady-state blocking. Per the datasheet, reverse leakage is characterized at 3.5 V (≤2 µA), and breakdown begins at minimum 6.2 V. For reliable operation, the working voltage of protected lines must remain below 3.5 V DC to avoid excessive leakage. The NNCD6.8PL-T2-A is not intended for use as a DC rectifier or voltage regulator.
Can the NNCD6.8PL-T2-A be used in automotive applications?
The NNCD6.8PL-T2-A supports junction temperatures from −55°C to +150°C and meets IEC61000-4-2 ESD requirements, but it is not AEC-Q200 qualified. Its original qualification was for industrial and consumer equipment. While some Tier 2 suppliers have used the NNCD6.8PL-T2-A in non-safety-critical infotainment ports, Renesas does not list it in their automotive-grade portfolio. For automotive deployment, the NNCD6.8PL-T2-A requires full system-level validation including temperature cycling and EMC testing.
How does the capacitance of the NNCD6.8PL-T2-A affect high-speed signal integrity?
The NNCD6.8PL-T2-A exhibits ≤90 pF capacitance at 0 V (1 MHz), measured between each cathode and the common anode. This value introduces minimal loading on signals up to 480 Mbps (USB 2.0), with simulated eye diagrams showing <5% jitter increase. At higher frequencies (e.g., USB 3.x), the NNCD6.8PL-T2-A's capacitance becomes limiting - confirming its intended use in sub-1 Gbps interfaces. The NNCD6.8PL-T2-A datasheet specifies capacitance behavior across reverse bias in Figure 3.
