Product details
Overview
NNCD16DA-T1-AT from Renesas Electronics is an ESD noise clipping diode in SC-76 (2-pin Super Mini Mold) package, designed for IEC61000-4-2 compliant external interface protection. It features 15.31–17.14 V breakdown voltage, 40 Ω dynamic impedance at 5 mA, 12 V reverse standoff, and 43 pF capacitance at 1 MHz - optimized for USB, HDMI, and audio jack surge suppression.
For engineers reviewing the NNCD16DA-T1-AT datasheet, NNCD16DA-T1-AT pinout, NNCD16DA-T1-AT application, or NNCD16DA-T1-AT equivalent, key selection criteria include ESD clamping voltage, low capacitance for high-speed signal integrity, surge power handling (85 W @ 10 μs), and Pb-free SC-76 footprint compatibility with automated SMT assembly.
Technical Context
This bidirectional ESD protection diode operates as a voltage-clamped shunt device across signal lines, triggering conduction when transient voltage exceeds its specified breakdown range. Its low dynamic impedance ensures rapid energy diversion during ESD events while maintaining minimal forward voltage drop under normal operation.
The device meets IEC61000-4-2 Level 4 (±30 kV contact discharge) and is rated for 85 W non-repetitive surge reverse power at 10 μs pulse width. Its 43 pF capacitance at 1 MHz supports data rates up to 480 Mbps in USB 2.0 applications without signal degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 15.31–17.14 V at 5 mA - defines minimum clamping threshold before conduction begins |
| Dynamic Impedance (ZZ) | 40 Ω at 5 mA - determines voltage overshoot during ESD transients (lower = tighter clamping) |
| Reverse Standoff Voltage (VRWM) | 12 V - maximum continuous operating voltage without leakage or conduction |
| Capacitance (Ct) | 43 pF at 1 MHz - limits signal distortion in high-speed interfaces like USB 2.0 |
| Surge Reverse Power (PRSM) | 85 W at 10 μs pulse - withstands IEC61000-4-2 Level 4 ESD pulses |
| ESD Withstand Voltage | ±30 kV contact discharge - certified per IEC61000-4-2 test standard |
| Package | SC-76 (2-pin Super Mini Mold) - 1.7 × 2.5 mm footprint, compatible with 0603 reflow profiles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR (Texas Instruments) | Lower 15 pF capacitance but 5.5 V VRWM; dual-channel in same SC-70 package | Better suited for >1 Gbps interfaces (e.g., USB 3.0); not rated for 12 V standby | Select when protecting higher-speed lines where <20 pF is mandatory and operating voltage ≤5.5 V |
| ESD9X5.0ST5G (ON Semiconductor) | 5.0 V VRWM, 65 pF, 30 kV HBM; SOD-923 package (1.0 × 0.6 mm) | Smaller footprint but higher capacitance; optimized for low-voltage logic I/O, not 12 V interfaces | Choose for space-constrained 3.3 V microcontroller GPIO protection, not 12 V signal lines |
Compared with TPD2E001DRYR and ESD9X5.0ST5G, the NNCD16DA-T1-AT uniquely supports 12 V reverse standoff with 43 pF and 85 W surge rating - making it the only option among the three qualified for 12 V-rated external ports requiring IEC61000-4-2 Level 4 compliance.

FAQ
What is the breakdown voltage range of the NNCD16DA-T1-AT?
The NNCD16DA-T1-AT has a guaranteed breakdown voltage range of 15.31 V to 17.14 V at 5 mA test current, measured using a 40 ms pulse per the official Renesas datasheet D18879EJ2V0DS. This defines the voltage threshold at which the diode begins conducting during ESD events, ensuring reliable clamping above the 12 V reverse standoff rating.
Does the NNCD16DA-T1-AT meet IEC61000-4-2 ESD immunity standards?
Yes, the NNCD16DA-T1-AT is explicitly rated for ±30 kV contact discharge per IEC61000-4-2 Level 4, as confirmed in the Renesas datasheet D18879EJ2V0DS. Its 85 W surge reverse power rating at 10 μs pulse width directly supports this certification, making it suitable for high-reliability external interface protection.
What is the capacitance value of the NNCD16DA-T1-AT and why does it matter?
The NNCD16DA-T1-AT exhibits 43 pF typical capacitance at 1 MHz and 0 V bias, per the Renesas datasheet. This low value minimizes signal distortion in high-speed digital interfaces such as USB 2.0, preserving rise/fall times and enabling reliable 480 Mbps data transmission without eye diagram closure.
Is the NNCD16DA-T1-AT RoHS compliant and what is its plating material?
Yes, the NNCD16DA-T1-AT is RoHS compliant with pure Sn (tin) lead plating, as stated in the Renesas ordering information section of datasheet D18879EJ2V0DS. The device contains no Pb in external electrodes or other parts, meeting JEDEC J-STD-020 reflow profile requirements for lead-free assembly.
What package type does the NNCD16DA-T1-AT use and what are its dimensions?
The NNCD16DA-T1-AT uses the SC-76 (2-pin Super Mini Mold) package, measuring 1.7 ± 0.1 mm in length, 2.5 ± 0.15 mm in width, and 0.9 ± 0.1 mm in height, with a cathode indicated by a beveled edge. This compact surface-mount outline enables high-density PCB layouts and compatibility with standard 0603 placement equipment.
