Product details
Overview
NNCD6.8RL(0)-T1-A from NEC Electronics is a quad-channel ESD noise clipping diode with common-anode configuration 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 endurance, and 200 mW total power dissipation - deployed for high-density external interface circuit protection in portable communication devices.
For engineers reviewing the NNCD6.8RL(0)-T1-A datasheet, NNCD6.8RL(0)-T1-A pinout, NNCD6.8RL(0)-T1-A application, or NNCD6.8RL(0)-T1-A equivalent, key selection criteria include verified 8 kV ESD immunity, low 10 pF junction capacitance for high-speed signal integrity, quad common-anode topology for compact USB/UART/HDMI port clamping, and compatibility with automated SMT assembly on 0.5 mm pitch PCBs.
Technical Context
This device implements four independent silicon PN-junction clamping diodes sharing a single anode terminal, optimized for transient voltage suppression in low-voltage digital interfaces. Its design targets fast response to ESD events (tr < 1 ns) while maintaining sub-10 pF inter-pin capacitance to avoid signal distortion on lines up to 100 Mbps.
The 5-pin flat-lead package enables surface-mount placement with 0.5 mm lead pitch and 1.6 × 1.2 mm body footprint, supporting reflow soldering per J-STD-020. Thermal resistance is characterized at 625°C/W on a 10 × 7.5 × 0.75 mm ceramic board, limiting continuous power handling but sustaining 2 W surge for 10 µs pulses.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DRYR | 4-channel, 0.5 pF typical capacitance, 12 kV IEC61000-4-2, 5-pin SOT-553 package | Lower capacitance suits USB 3.0/PCIe; higher ESD rating for medical-grade ports | Preferred when signal bandwidth exceeds 5 Gbps or regulatory requirement exceeds 8 kV |
| ESD5Z3.3T5G | Single-channel, 3.3 V breakdown, 0402 package, 0.6 pF capacitance | Requires four discrete placements; lacks integrated common-anode convenience | Select only when board space allows discrete routing and cost sensitivity outweighs assembly efficiency |
Compared with TPD4E001DRYR and ESD5Z3.3T5G, the NNCD6.8RL(0)-T1-A delivers optimal balance of proven 8 kV robustness, 10 pF interface transparency, and quad-integrated layout efficiency for cost-sensitive 3.3 V/5 V embedded interfaces - making it ideal for volume production of industrial HMI and consumer peripherals where qualification stability matters more than ultra-low capacitance.

FAQ
What is the exact breakdown voltage range specified for NNCD6.8RL(0)-T1-A?
The NNCD6.8RL(0)-T1-A has a guaranteed breakdown voltage range of 6.2 V to 7.1 V measured at 5 mA test current, per its original NEC D15992EJ1V0DS00 datasheet. This range ensures reliable clamping above 3.3 V logic levels while staying safely below 5 V rail limits, and applies uniformly across all four cathode-to-anode channels (K1–K4 to A) in the device.
Does NNCD6.8RL(0)-T1-A support IEC61000-4-2 Level 4 ESD protection?
Yes, the NNCD6.8RL(0)-T1-A is rated for ≥8 kV contact discharge per IEC61000-4-2, which corresponds to Level 4 - the highest severity level defined in that standard. This rating was validated during NEC's original qualification and remains valid for legacy designs meeting the 2003 specification; no derating is required for standard industrial deployment.
What is the maximum junction capacitance of NNCD6.8RL(0)-T1-A and under what conditions is it measured?
The maximum junction capacitance of NNCD6.8RL(0)-T1-A is 10 pF, measured at 0 V reverse bias and 1 MHz frequency. This value is specified across all four diode channels (A–K1 through A–K4) and reflects the device's suitability for high-speed digital interfaces such as USB 2.0, where low capacitance prevents signal integrity loss.
Can NNCD6.8RL(0)-T1-A be used in place of discrete 0402 ESD diodes in new designs?
Yes, the NNCD6.8RL(0)-T1-A can replace four discrete 0402 ESD diodes in new designs, provided the layout accommodates its 5-pin flat-lead package (1.6 × 1.2 mm) and common-anode topology. It reduces component count, improves placement accuracy, and ensures matched electrical characteristics across all four channels - critical for differential pair protection.
Is NNCD6.8RL(0)-T1-A still manufactured and supported by Renesas Electronics?
No - NNCD6.8RL(0)-T1-A is a discontinued NEC product, not actively manufactured or supported by Renesas Electronics post-merger. However, Aetrix Electronics maintains legacy inventory and provides full traceability, datasheet documentation, and technical support for ongoing production use in long-lifecycle industrial and medical systems.
