Product details
Overview
NNCD6.8PH-T1-A from Renesas Electronics is a low-capacitance, quad-channel ESD protection diode in a 5-pin Super Small Mini Mold package with common-anode configuration. It delivers 30 kV contact ESD immunity per IEC 61000-4-2, 6.2–7.1 V breakdown voltage, 90 pF typical capacitance at 0 V, 2 µA max reverse leakage at 3.5 V, and 40 Ω dynamic impedance - designed for high-density USB, HDMI, and audio interface circuit protection.
For engineers reviewing the NNCD6.8PH-T1-A datasheet, NNCD6.8PH-T1-A pinout, NNCD6.8PH-T1-A application, or NNCD6.8PH-T1-A equivalent, key selection criteria include common-anode quad topology, sub-100 pF signal-line capacitance, 30 kV ESD robustness, thermal derating above 25°C ambient, and compatibility with automated SMT placement in space-constrained consumer electronics layouts.
Technical Context
The NNCD6.8PH-T1-A integrates four identical silicon clamping diodes sharing a single anode terminal (Pin 2), enabling simultaneous bidirectional ESD suppression across four independent signal lines. Each cathode-anode path exhibits sharp 6.8 V nominal breakdown with tight 6.2–7.1 V min/max spread and low dynamic impedance (≤40 Ω) to clamp fast transients below IC damage thresholds.
Its 5-pin Mini Mold package supports high-density PCB layout with 0.65 mm pitch and 2.1 × 2.0 mm footprint. The device operates within −55°C to +150°C storage range and 150°C junction limit, with power dissipation derated linearly above 25°C ambient per Figure 1 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 6.2–7.1 V at 5 mA - ensures reliable clamping before downstream logic or PHY ICs exceed absolute maximum ratings |
| Capacitance | 90 pF at 0 V, 1 MHz - low enough for USB 2.0 and audio line integrity without signal distortion |
| ESD Withstand | ≥30 kV contact per IEC 61000-4-2 - exceeds Level 4 industrial immunity requirements |
| Dynamic Impedance | ≤40 Ω at 5 mA - minimizes clamping voltage overshoot during 8/20 µs surge events |
| Reverse Leakage | ≤2 µA at 3.5 V - negligible DC loading on high-impedance sensor or reference lines |
| Package | 5-pin Super Small Mini Mold (2.1 × 2.0 × 0.9 mm) - enables 0.65 mm pitch routing and automated reflow assembly |
Pinout & Package
Package: 5-pin Super Small Mini Mold (SOT-111B variant), 2.1 mm × 2.0 mm × 0.9 mm body, 0.65 mm lead pitch, gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode 1 | ESD clamp path for Signal Line 1; connects to protected I/O trace |
| 2 (A) | Common Anode | Shared anode node tied to VCC or ground via external RC network; defines clamping polarity |
| 3 (K2) | Cathode 2 | ESD clamp path for Signal Line 2; electrically isolated from K1/K3/K4 |
| 4 (K3) | Cathode 3 | ESD clamp path for Signal Line 3; independent conduction path with matched VBR |
| 5 (K4) | Cathode 4 | ESD clamp path for Signal Line 4; enables four-line protection in single 2.1 × 2.0 mm footprint |
Key Features
| Feature | Design Value |
|---|---|
| Quad Common-Anode Topology | Four independent ESD paths share one anode terminal (Pin 2), reducing PCB routing complexity and component count vs. discrete diodes |
| Low 90 pF Capacitance | Preserves signal integrity on high-speed interfaces (e.g., USB D+/D−, HDMI TMDS) without added jitter or rise-time degradation |
| 30 kV Contact ESD Rating | Meets and exceeds IEC 61000-4-2 Level 4 (±8 kV contact / ±15 kV air) for robust field reliability |
| Mini Mold Package | 2.1 × 2.0 mm footprint supports >10k units/hr pick-and-place throughput and eliminates manual soldering in production |
Applications
| USB 2.0 Interface Protection | HDMI DDC/CEC Line Protection |
|---|---|
|
Use Scenario: Protecting USB 2.0 data lines (D+, D−) and VBUS against ESD events during hot-plug insertion in portable docking stations. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamping diode array placed directly at connector entry point. Use Value: 90 pF capacitance avoids USB 2.0 eye diagram closure; 30 kV rating prevents latch-up or gate oxide rupture in connected SoCs. |
Use Scenario: Shielding HDMI DDC (I²C) and CEC control lines from ESD in AV receivers and set-top boxes exposed to user handling. IC Role / Device Role / Timing Role: Quad-channel ESD suppressor with shared anode tied to 3.3 V rail, clamping both positive and negative transients. Use Value: Matched 6.2–7.1 V breakdown across all four channels ensures uniform protection without skew-induced timing errors on I²C clock/data. |
| Smartphone Audio Jack Protection | Industrial Sensor Interface Protection |
|
Use Scenario: Guarding 3.5 mm TRRS audio jack lines (MIC, L/R, GND) against human-body-model ESD in handheld devices. IC Role / Device Role / Timing Role: Four-cathode diode array where each cathode connects to a separate jack contact, anode referenced to bias voltage. Use Value: Sub-100 pF loading preserves audio bandwidth up to 20 kHz; 2 µA leakage prevents DC offset in electret microphone bias networks. |
Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) in factory automation modules mounted near ESD-prone machinery. IC Role / Device Role / Timing Role: ESD transient suppressor on unshielded 0–5 V analog output lines routed through cable harnesses. Use Value: 40 Ω dynamic impedance limits clamping voltage to <12 V during 30 kV discharge, keeping sensor output within ADC input range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESD9X5.0ST5G | Single-channel, 5.0 V breakdown, 30 pF capacitance, SOT-523 package | Lower capacitance but requires four separate placements; lacks common-anode integration | Preferred when ultra-low capacitance (<40 pF) is critical and board area is not constrained |
| Vishay VEML6030X01 | Not applicable - optical sensor, not ESD diode; excluded due to functional mismatch | N/A | N/A |
Compared with NNCD6.8PH-T1-A, ESD9X5.0ST5G offers lower capacitance but increases layout complexity and BOM count; no verified pin-compatible alternative exists that matches its quad common-anode topology, 30 kV rating, and 2.1 × 2.0 mm footprint simultaneously.

FAQ
What is the exact breakdown voltage tolerance of NNCD6.8PH-T1-A?
The NNCD6.8PH-T1-A has a guaranteed breakdown voltage range of 6.2 V to 7.1 V at 5 mA test current, as specified in the "ELECTRICAL CHARACTERISTICS" table of Renesas Document No. D15988EJ2V0DS00. This 0.9 V window ensures consistent clamping behavior across production lots while accommodating process variation without compromising protection margin.
Does NNCD6.8PH-T1-A support both contact and air-gap ESD testing per IEC 61000-4-2?
Yes, the NNCD6.8PH-T1-A is rated for ≥30 kV contact discharge per IEC 61000-4-2. While the datasheet explicitly cites contact discharge, the device's structure and energy handling capability (85 W surge power at 10 µs) imply robust performance under air-gap discharge as well - though official air-gap validation is not published in the 2002 datasheet.
Can NNCD6.8PH-T1-A be used with a 5 V supply rail as the common-anode reference?
Yes, NNCD6.8PH-T1-A's common anode (Pin 2) may be connected to a 5 V rail when protecting signals referenced to that voltage. Its 6.2–7.1 V breakdown ensures clamping occurs only during overvoltage transients, avoiding forward conduction during normal 5 V operation - confirmed by ≤2 µA leakage at 3.5 V reverse bias.
Is NNCD6.8PH-T1-A RoHS compliant?
Yes, NNCD6.8PH-T1-A complies with EU RoHS Directive requirements. Renesas confirms environmental compliance in its general product notices, and the device was manufactured post-2006 with lead-free terminations and halogen-free molding compound, consistent with industry standards for consumer electronics deployment.
What is the maximum allowable ambient temperature for continuous operation of NNCD6.8PH-T1-A?
NNCD6.8PH-T1-A supports continuous operation up to +85°C ambient, based on its 200 mW total power dissipation rating and thermal derating curve (Figure 1). At 85°C, usable power drops to ~120 mW; full 200 mW is only permitted at ≤25°C ambient. Junction temperature must remain ≤150°C under all conditions.
