Product details
Overview
NNCD6.8RL-T1-AT from Renesas 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, ≤10 pF capacitance at 0 V, ≤2 µA reverse leakage at 3.5 V, 8 kV IEC61000-4-2 contact discharge rating, and 200 mW total power dissipation - designed for high-density external interface circuit protection in consumer and industrial electronics.
For engineers reviewing the NNCD6.8RL-T1-AT datasheet, NNCD6.8RL-T1-AT pinout, NNCD6.8RL-T1-AT application, or NNCD6.8RL-T1-AT equivalent, key selection criteria include common-anode quad configuration, low-clamping-voltage ESD response, sub-10 pF signal-line loading, thermal performance on ceramic substrates, and compatibility with automated SMT assembly for USB, HDMI, and audio jack interfaces.
Technical Context
The NNCD6.8RL-T1-AT implements four identical silicon PN-junction clipping diodes sharing a single anode terminal (Pin 2), enabling simultaneous bidirectional ESD clamping across four independent signal lines. Each cathode-anode path delivers precise 6.2–7.1 V breakdown with tight distribution and low dynamic impedance during transient events.
Its flat-lead 5-pin package supports high-density PCB layout with 0.5 mm pitch and 1.6 × 1.2 mm footprint, while thermal characterization shows 625°C/W transient thermal impedance on a 10 × 7.5 × 0.75 mm ceramic board - confirming suitability for short-duration surge absorption without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6.2–7.1 V at 5 mA - defines minimum clamping threshold to protect downstream ICs from overvoltage transients |
| Capacitance (Ct) | ≤10 pF at 0 V, 1 MHz - ensures minimal signal distortion on high-speed interfaces like USB 2.0 or audio lines |
| ESD Rating | ≥8 kV contact discharge per IEC61000-4-2 - meets industrial-grade immunity requirements for external ports |
| Reverse Leakage (IR) | ≤2 µA at 3.5 V - guarantees negligible DC loading on bias-sensitive analog or reference circuits |
| Total Power Dissipation | 200 mW at TA = 25°C - sets maximum continuous power handling before thermal derating begins |
| Surge Reverse Power | 2 W (t = 10 µs, single pulse) - quantifies peak transient energy absorption capability |
Pinout & Package
Package: 5-pin Super Small Mini Mold (Flat Lead Type), 1.6 × 1.2 × 0.5 mm body, 0.5 mm lead pitch, gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 (K1) | Clamps positive transients on Signal Line 1 to common anode; enables bidirectional protection when paired with external series impedance |
| 2 | Anode (Common) | Shared anode node connected to VCC or ground via external resistor; determines clamping polarity and reference level |
| 3 | Cathode 2 (K2) | Independent clamping path for Signal Line 2; electrically isolated from K1/K3/K4 except through common anode |
| 4 | Cathode 3 (K3) | Third protected signal line; maintains same VBR, Ct, and IR specs as K1 and K2 |
| 5 | Cathode 4 (K4) | Fourth protected signal line; allows compact protection of multi-lane interfaces (e.g., differential pairs + sideband signals) |
Key Features
| Feature | Design Value |
|---|---|
| Quad Common-Anode Configuration | Four independent ESD paths share one anode terminal, reducing PCB routing complexity and component count vs. discrete diodes |
| Low Capacitance (≤10 pF) | Preserves signal integrity on data lines up to 480 Mbps without measurable rise-time degradation |
| IEC61000-4-2 Certified (8 kV Contact) | Validated ESD robustness eliminates need for additional system-level testing on protected interfaces |
| Super Small Mini Mold Package | 1.6 × 1.2 mm footprint enables placement adjacent to connectors with no trace stubs or impedance discontinuities |
| Automated Assembly Compatible | Gull-wing leads and flat-lead geometry support standard reflow profiles and AOI inspection without tombstoning |

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 NZQ6V8B | Same 6.8 V nominal breakdown, but dual-channel (4-pin SOIC); higher 15 pF capacitance; 12 kV air/8 kV contact rating | Requires two devices for quad protection; larger 3.0 × 1.5 mm footprint limits routing density near connectors | Preferred where higher ESD margin is prioritized over board space and capacitance |
| Vishay ESD9X5.0ST5G | 5.0 V breakdown, 5-pin SOT-553 package; 12 pF capacitance; 12 kV air/8 kV contact rating; lower 150 mW power rating | Better suited for 3.3 V logic rails; less effective clamping headroom for 5 V interfaces due to lower VBR | Select when protecting 3.3 V I/O with tighter voltage margins and acceptable capacitance trade-off |
Compared with NZQ6V8B and ESD9X5.0ST5G, the NNCD6.8RL-T1-AT offers optimal balance of low capacitance, quad integration, and 5 V interface compatibility - making it ideal for space-constrained USB/HDMI designs requiring predictable 6.8 V clamping without sacrificing signal integrity.

FAQ
What is the exact breakdown voltage range specified for NNCD6.8RL-T1-AT?
The NNCD6.8RL-T1-AT has a guaranteed breakdown voltage range of 6.2 V to 7.1 V at 5 mA test current, measured across each individual cathode-to-anode path (A–K1, A–K2, A–K3, A–K4). This specification is confirmed in the official Renesas datasheet D15992EJ1V0DS00 and applies under standard conditions (TA = 25°C). The NNCD6.8RL-T1-AT maintains this tolerance across its qualified operating temperature range.
Does NNCD6.8RL-T1-AT support bidirectional ESD protection?
Yes, the NNCD6.8RL-T1-AT provides bidirectional ESD protection when the common anode (Pin 2) is biased to a fixed DC voltage - typically VCC or ground - allowing each cathode to clamp both positive and negative transients relative to that reference. This behavior is inherent to its PN-junction structure and is validated per IEC61000-4-2 contact discharge testing. The NNCD6.8RL-T1-AT achieves ≥8 kV in both polarities under standard test conditions.
What is the maximum allowable reverse voltage for continuous operation of NNCD6.8RL-T1-AT?
The NNCD6.8RL-T1-AT is rated for a maximum reverse voltage of 3.5 V in continuous operation, beyond which reverse leakage current exceeds 2 µA. This value is derived from the "REVERSE LEAKAGE" specification in the Electrical Characteristics table (IR ≤ 2 µA at VR = 3.5 V). Operating the NNCD6.8RL-T1-AT above 3.5 V in steady-state risks excessive leakage and potential thermal instability, though transient surges up to 8 kV are safely clamped.
Can NNCD6.8RL-T1-AT be used in automotive applications?
The NNCD6.8RL-T1-AT is classified as a Standard-grade Renesas product, intended for computers, office equipment, communications gear, and consumer electronics - not for automotive use. It lacks AEC-Q200 qualification, extended temperature range validation (−40°C to +125°C), or PPAP documentation. For automotive infotainment or body control modules, a qualified alternative such as the NUP4105MR6T1G must be selected instead of the NNCD6.8RL-T1-AT.
Is the NNCD6.8RL-T1-AT RoHS compliant?
Yes, the NNCD6.8RL-T1-AT complies with the EU RoHS Directive, as confirmed by Renesas Electronics' environmental compliance documentation. The device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits. This RoHS compliance applies to all units shipped under the NNCD6.8RL-T1-AT part number, including those manufactured prior to the April 2010 Renesas merger, as verified in Renesas' material declarations and substance lists.
