Product details
Overview
NNCD6.2DA-T1-AT from Renesas Electronics is an ESD noise clipping diode designed for transient voltage suppression in external interface circuits. It features a breakdown voltage of 5.84–6.55 V, dynamic impedance of 50 Ω at 5 mA, reverse leakage ≤2 μA at 3.0 V, capacitance of 120 pF at 1 MHz, and IEC61000-4-2 rated ESD protection up to ±30 kV. It is used in USB, audio jack, and parallel interface protection.
For engineers reviewing the NNCD6.2DA-T1-AT datasheet, NNCD6.2DA-T1-AT pinout, NNCD6.2DA-T1-AT application, or NNCD6.2DA-T1-AT equivalent, this page delivers verified electrical parameters, SC-76 package details, ESD endurance data, and direct alternatives for interface-level surge protection design.
Technical Context
This device operates as a unidirectional clamping diode with cathode-anode polarity, optimized for fast response to electrostatic discharge transients per IEC61000-4-2 Level 4 (±30 kV contact). Its low dynamic impedance (50 Ω) ensures effective voltage limiting during surge events while maintaining minimal signal distortion in high-speed lines.
The NNCD6.2DA-T1-AT is specified for surface-mount use on standard 30 mm × 30 mm × 1.6 mm glass epoxy PCBs, with a maximum power dissipation of 200 mW and surge reverse power rating of 85 W (10 μs pulse). Junction temperature is rated to 150°C, supporting industrial ambient operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 5.84–6.55 V at 5 mA - defines clamping threshold for ESD transients |
| Dynamic Impedance (ZZ) | 50 Ω at 5 mA - determines voltage overshoot under surge current |
| Reverse Leakage (IR) | ≤2 μA at 3.0 V - ensures low standby power loss in protected signal paths |
| Capacitance (Ct) | 120 pF at 1 MHz, 0 V bias - impacts high-frequency signal integrity on data lines |
| ESD Withstand | ±30 kV per IEC61000-4-2 - validated immunity for consumer/industrial interface ports |
| Surge Power (PRSM) | 85 W (10 μs pulse) - supports single-event transient energy absorption |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 2-channel, 0.9 pF per line, 8 kV IEC61000-4-2 - lower capacitance but lower ESD rating | Targeted at high-speed USB 2.0/3.0 where <1 pF is critical; not suitable for ±30 kV zones | Select when signal bandwidth >100 MHz and ESD threat is ≤8 kV; NNCD6.2DA-T1-AT preferred for robustness-critical interfaces |
| ESD9X5.0ST5G | Single-line, 5.0 V VBR, 150 pF, ±30 kV - higher capacitance, same ESD level | Better for low-speed lines (e.g., GPIO, buttons); less ideal for 12–48 MHz parallel buses due to Ct | Choose for cost-sensitive designs needing identical ESD rating; NNCD6.2DA-T1-AT offers superior ZZ (50 Ω vs. 80 Ω) for tighter voltage control |
Compared with TPD2E001DRYR and ESD9X5.0ST5G, the NNCD6.2DA-T1-AT delivers the lowest dynamic impedance (50 Ω) among ±30 kV-rated SC-76 diodes, enabling tighter clamping voltage control on medium-speed digital lines without sacrificing PCB area or thermal margin.

FAQ
What is the breakdown voltage range of the NNCD6.2DA-T1-AT?
The NNCD6.2DA-T1-AT has a guaranteed breakdown voltage range of 5.84 V to 6.55 V, measured at 5 mA DC test current per the official Renesas datasheet D18879EJ2V0DS. This range defines the minimum and maximum voltage at which the diode enters avalanche conduction during ESD events, ensuring predictable clamping behavior across production lots.
Is the NNCD6.2DA-T1-AT RoHS compliant?
Yes, the NNCD6.2DA-T1-AT is RoHS compliant. Its lead plating uses pure tin (Sn), and the datasheet explicitly states "Pb-free (This product does not contain Pb in the external electrode and other parts.)". It meets EU RoHS Directive requirements for restricted substances and is suitable for environmentally regulated markets.
What package type does the NNCD6.2DA-T1-AT use?
The NNCD6.2DA-T1-AT uses the 2-pin Super Mini Mold package, also known as SC-76, with exact dimensions of 2.5 ± 0.15 mm in length, 1.7 ± 0.1 mm in width, and 1.25 ± 0.1 mm in height. The cathode is marked by a visible band on the package body, consistent with JEDEC SC-76 mechanical standards.
Can the NNCD6.2DA-T1-AT be used for bidirectional ESD protection?
No, the NNCD6.2DA-T1-AT is a unidirectional ESD protection diode. Its electrical characteristics-including breakdown voltage specification and cathode/anode polarity-are defined for single-polarity clamping (anode-to-ground configuration). For bidirectional protection, a dual-diode array or symmetric TVS device would be required instead of the NNCD6.2DA-T1-AT.
What is the maximum surge reverse power rating for the NNCD6.2DA-T1-AT?
The NNCD6.2DA-T1-AT has a surge reverse power rating (PRSM) of 85 W under non-repetitive conditions with a 10 μs pulse width, as specified in the Absolute Maximum Ratings table of the Renesas datasheet. This rating reflects its ability to absorb single high-energy ESD transients without failure when mounted on a standard 30 mm × 30 mm × 1.6 mm glass epoxy PCB.
