Product details
Overview
NNCD16DA(0)-T1-AT from Renesas Electronics is an ESD noise clipping diode designed for external interface circuit protection. It features a breakdown voltage of 15.31–17.14 V, dynamic impedance ≤40 Ω at 5 mA, reverse leakage ≤2 μA at 12 V, capacitance of 43 pF at 0 V/1 MHz, and IEC61000-4-2 rated ESD immunity up to ±30 kV. It is used in USB, audio jack, and display port interfaces to suppress electrostatic discharge transients.
For engineers reviewing the NNCD16DA(0)-T1-AT datasheet, NNCD16DA(0)-T1-AT pinout, NNCD16DA(0)-T1-AT application, or NNCD16DA(0)-T1-AT equivalent, this page delivers verified electrical parameters, SC-76 package dimensions, ESD clamping behavior, junction temperature limits, and direct alternative options for interface-level transient suppression.
Technical Context
This device operates as a unidirectional silicon avalanche diode optimized for fast-response ESD clamping in low-capacitance signal paths. Its 43 pF capacitance at 0 V enables use on high-speed lines without signal integrity degradation, while its 85 W surge reverse power rating (tT = 10 μs) supports robust transient absorption per IEC61000-4-2 Level 4 testing.
The NNCD16DA(0)-T1-AT exhibits a typical dynamic impedance of 40 Ω at 5 mA forward current, ensuring low clamping voltage during ESD events. Its 150 °C maximum junction temperature and −55 to +150 °C storage range support operation in industrial and consumer environments with thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 15.31–17.14 V - defines minimum voltage at which diode enters avalanche conduction to clamp ESD transients |
| Dynamic Impedance (ZZ) | ≤40 Ω at 5 mA - determines clamping voltage rise (VCL = VBR + IPP × ZZ) during surge events |
| Capacitance (Ct) | 43 pF at 0 V, 1 MHz - low enough for USB 2.0 and HDMI DDC line protection without signal attenuation |
| ESD Withstand | ±30 kV contact discharge per IEC61000-4-2 - meets highest immunity level for end-equipment certification |
| Surge Reverse Power (PRSM) | 85 W (10 μs pulse) - specifies single-pulse energy handling capability for transient suppression |
| Junction Temperature (Tj) | 150 °C max - sets upper thermal limit for PCB layout and power derating calculations |

Applications
| USB 2.0 Data Lines | HDMI Hot Plug Detect |
|---|---|
Use Scenario: Protecting D+ and D− differential pairs from ESD events during cable insertion/removal. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between signal line and ground to shunt transient current before it reaches USB transceiver. Use Value: 43 pF capacitance avoids signal rise-time degradation; ±30 kV rating ensures compliance with USB-IF ESD test requirements. | Use Scenario: Safeguarding the HDMI hot plug detect (HPD) pin against user-induced static discharge. IC Role / Device Role / Timing Role: Standoff diode connected between HPD line and chassis ground to clamp voltage spikes above 15.31 V. Use Value: 15.31–17.14 V breakdown range aligns with HPD logic-high threshold (typically 2.0–5.5 V), preventing false disconnect detection. |
| Audio Jack Tip/Ring | DisplayPort AUX Channel |
Use Scenario: Shielding analog audio tip/ring contacts from ESD during headphone insertion into portable devices. IC Role / Device Role / Timing Role: Low-leakage (≤2 μA) clamping diode referenced to audio ground to preserve DC bias integrity. Use Value: 2 μA max reverse leakage prevents audible pop/crackle caused by bias shift in amplifier input stages. | Use Scenario: Protecting DisplayPort AUX CH (bidirectional control channel) from ESD during docking/undocking. IC Role / Device Role / Timing Role: Signal-line protector with 43 pF capacitance placed inline with AUX± differential pair. Use Value: Capacitance matches DP AUX channel bandwidth (up to ~1 MHz), avoiding communication errors during link training. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9X15VD-2/TR | 15 V nominal breakdown, 30 pF capacitance, SOD-923 package (1.0 × 0.6 mm) | Smaller footprint; lower capacitance better suited for >100 Mbps digital lines | Select when board space is constrained and signal bandwidth exceeds USB 2.0 requirements |
| TPD2E001DRYR | 15 V breakdown, dual-channel, 15 pF per line, SOT-553 package | Integrated dual-diode array for differential pair protection; lower capacitance but higher cost | Choose for differential ESD protection where matched capacitance and layout symmetry are critical |
Compared with ESD9X15VD-2/TR and TPD2E001DRYR, the NNCD16DA(0)-T1-AT offers higher surge power handling (85 W vs. 30–50 W), larger package tolerance for rework, and proven field reliability in consumer interface applications-making it optimal for cost-sensitive, medium-speed I/O protection where thermal margin matters.

FAQ
What is the breakdown voltage range specified for NNCD16DA(0)-T1-AT?
The NNCD16DA(0)-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 range ensures consistent clamping behavior across production lots and defines the onset voltage for avalanche conduction during ESD events.
Does NNCD16DA(0)-T1-AT support bidirectional ESD protection?
No, NNCD16DA(0)-T1-AT is a unidirectional ESD protection diode. It clamps only positive transients on the anode relative to cathode (ground). For bidirectional protection, two devices must be used in series opposition or a dedicated bidirectional part such as the NNCD16DAR should be selected instead of NNCD16DA(0)-T1-AT.
What is the maximum allowable reverse voltage for continuous operation of NNCD16DA(0)-T1-AT?
The NNCD16DA(0)-T1-AT does not specify a DC reverse working voltage (VRWM) in its datasheet. Its design intent is transient suppression-not steady-state blocking. The 12 V value listed in the Electrical Characteristics table is the test condition for measuring reverse leakage (IR ≤ 2 μA), not a rated continuous operating voltage. System design must ensure normal operating signals remain well below the 15.31 V breakdown threshold.
Is NNCD16DA(0)-T1-AT compatible with lead-free reflow soldering processes?
Yes, NNCD16DA(0)-T1-AT uses pure Sn (tin) lead plating and is explicitly rated for Pb-free assembly. Its package construction and thermal specifications-including 150 °C maximum junction temperature and compatibility with standard JEDEC J-STD-020 moisture sensitivity level (MSL) profiles-support full lead-free reflow soldering per IPC-J-STD-020.
How does the 43 pF capacitance of NNCD16DA(0)-T1-AT affect high-speed signal integrity?
The 43 pF capacitance of NNCD16DA(0)-T1-AT is measured at 0 V and 1 MHz, and is appropriate for signal lines up to ~20 MHz. In USB 2.0 (480 Mbps) applications, this capacitance introduces minimal rise-time degradation when placed with short traces; however, it is not recommended for USB 3.0 SuperSpeed (5 Gbps) or PCIe Gen3+ lanes where sub-1 pF loading is required. Always verify eye diagram margins in final layout.
