Product details
Overview
NNCD6.8RL(0)-T1-AT 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 rating, and 200 mW total power dissipation - deployed for high-density external interface circuit protection.
For engineers reviewing the NNCD6.8RL(0)-T1-AT datasheet, NNCD6.8RL(0)-T1-AT pinout, NNCD6.8RL(0)-T1-AT application, or NNCD6.8RL(0)-T1-AT equivalent, key selection criteria include ESD robustness (8 kV contact), low capacitance (<10 pF), quad common-anode topology, flat-lead SMT package footprint, and compliance with IEC61000-4-2 Level 4.
Technical Context
This device implements four independent silicon PN-junction clamping diodes sharing a single anode terminal, enabling simultaneous transient suppression across four signal lines. Its low 10 pF capacitance at 0 V and fast response support high-speed data interfaces including USB 2.0 and HDMI DDC lines.
The 5-pin flat-lead package integrates all four cathodes (K1–K4) and one common anode (A) on a 1.6 × 1.2 mm body with 0.5 mm pitch, optimized for automated placement and board space efficiency in compact consumer electronics.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Single-channel, 0.5 pF typical capacitance, 12 kV IEC61000-4-2 rating, 6-pin X2SON | Lower capacitance but requires four discrete units; no common-anode simplification | Preferred when ultra-low capacitance (<1 pF) is critical and board area allows discrete layout |
| ESD5Z3.3T5G | Single-channel, 3.3 V working voltage, 12 kV rating, SOD-523 package | Lower clamping voltage unsuitable for 5 V tolerant interfaces; not quad-integrated | Used where lower trigger voltage is required and multi-diode integration is unnecessary |
Compared with TPD2E001DRYR and ESD5Z3.3T5G, the NNCD6.8RL(0)-T1-AT delivers integrated quad protection with matched 6.8 V clamping and 0.5 mm pitch SMT compatibility - reducing BOM count and PCB real estate versus discrete alternatives, while meeting industrial-grade 8 kV ESD immunity without over-clamping sensitive 5 V logic.

FAQ
What is the exact breakdown voltage range specified for NNCD6.8RL(0)-T1-AT?
The NNCD6.8RL(0)-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 A–K diode pair. This range ensures consistent clamping behavior across all four channels and aligns with its designation as a 6.8 V nominal ESD suppressor. The specification is validated per the datasheet D15992EJ1V0DS00.
Does NNCD6.8RL(0)-T1-AT support IEC61000-4-2 Level 4 ESD immunity?
Yes, the NNCD6.8RL(0)-T1-AT is rated for ≥8 kV contact discharge per IEC61000-4-2, satisfying Level 4 - the highest severity class defined in the standard. This rating applies to all four channels simultaneously and is verified under standardized test conditions with 150 pF/330 Ω network, as documented in the original NEC datasheet.
What is the maximum junction temperature for NNCD6.8RL(0)-T1-AT during operation?
The NNCD6.8RL(0)-T1-AT has a maximum rated junction temperature of +150°C, as specified in its Absolute Maximum Ratings table. This limit governs thermal design margins during repetitive ESD events or sustained surge conditions, and must be respected alongside its 200 mW total power dissipation rating and transient thermal impedance profile.
Can NNCD6.8RL(0)-T1-AT be used in automotive applications?
The NNCD6.8RL(0)-T1-AT is classified as a Standard quality grade device per NEC's internal quality categorization and was not qualified to AEC-Q101 or automotive temperature ranges. It is intended for consumer, industrial, and medical non-life-support applications - not for under-hood or safety-critical automotive systems requiring extended temperature or qualification compliance.
How is the common-anode configuration implemented in NNCD6.8RL(0)-T1-AT?
The NNCD6.8RL(0)-T1-AT integrates four separate PN junctions sharing Pin 2 as the common anode (A), with Pins 1, 3, 4, and 5 serving as individual cathodes (K1–K4). This architecture allows simultaneous clamping of four signal lines to a single reference node - simplifying grounding strategy and reducing PCB trace inductance compared to discrete diode solutions.
