Product details
Overview
NNCD3.6DA-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 3.4–3.8 V, dynamic impedance ≤130 Ω at 5 mA, reverse leakage ≤10 μA at 1.0 V, capacitance of 210 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 on consumer electronics.
For engineers reviewing the NNCD3.6DA-T1-AT datasheet, NNCD3.6DA-T1-AT pinout, NNCD3.6DA-T1-AT application, or NNCD3.6DA-T1-AT equivalent, this page delivers verified electrical specs, SC-76 package details, real-world ESD protection use cases, and two confirmed alternative parts with documented technical differences.
Technical Context
This device operates as a unidirectional clamping diode optimized for electrostatic discharge immunity per IEC61000-4-2. Its low dynamic impedance (≤130 Ω) ensures rapid voltage clamping during fast transients, while its 210 pF capacitance at 1 MHz supports signal integrity in low-speed interfaces like legacy parallel ports and audio lines.
The NNCD3.6DA-T1-AT is rated for 85 W surge reverse power (tT = 10 μs), 200 mW steady-state power dissipation on a standard 30 mm × 30 mm × 1.6 mm FR-4 PCB, and junction temperature up to 150°C - confirming suitability for surface-mounted consumer and industrial interface protection without active thermal management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Lower capacitance (12 pF), dual-channel, same SC-70 package - but lower ESD rating (±8 kV contact) | Better suited for high-speed data lines (e.g., I²C), not recommended for 30 kV-level interface protection | Select NNCD3.6DA-T1-AT when full IEC61000-4-2 Level 4 compliance is mandatory |
| ESD9X3.3SCT5G | 3.3 V nominal VBR, 120 pF, SOD-923 package - slightly smaller footprint but lower surge power (50 W) | Acceptable for cost-sensitive consumer audio ports where 30 kV rating is not required | Choose NNCD3.6DA-T1-AT for higher reliability in industrial or field-deployed equipment |
Compared with TPD2E001DRYR and ESD9X3.3SCT5G, the NNCD3.6DA-T1-AT delivers superior ESD robustness (±30 kV) and surge power (85 W) at the expense of higher capacitance - making it optimal for legacy low-speed interfaces where immunity trumps bandwidth.

FAQ
What is the breakdown voltage range of the NNCD3.6DA-T1-AT?
The NNCD3.6DA-T1-AT has a guaranteed breakdown voltage range of 3.4 V to 3.8 V at 5 mA test current, measured per the IEC61000-4-2 standard. This range ensures consistent clamping behavior across production lots and allows safe operation with 3.3 V logic systems without risk of premature conduction during normal operation.
Is the NNCD3.6DA-T1-AT RoHS compliant?
Yes, the NNCD3.6DA-T1-AT is RoHS compliant. As stated in the ordering information, it uses pure Sn (tin) lead plating and contains no Pb in external electrodes or other parts. This compliance is confirmed in the original NEC Electronics datasheet D18879EJ2V0DS and maintained under Renesas Electronics' product stewardship.
What package type does the NNCD3.6DA-T1-AT use?
The NNCD3.6DA-T1-AT uses the SC-76 package, also referred to as 2-pin Super Mini Mold. Its dimensions are 1.7 ± 0.1 mm × 2.5 ± 0.15 mm × 0.9 ± 0.1 mm, with cathode polarity marked by a band. This compact surface-mount package enables direct placement at connector entry points for optimal ESD protection.
Can the NNCD3.6DA-T1-AT be used for bidirectional ESD protection?
No, the NNCD3.6DA-T1-AT is a unidirectional diode intended for line-to-ground clamping only. It provides protection against positive transients on the anode relative to cathode (ground). For bidirectional protection, two devices must be used in series opposition or a dedicated bidirectional TVS array should be selected.
What is the maximum surge power rating for the NNCD3.6DA-T1-AT?
The NNCD3.6DA-T1-AT is rated for 85 W of surge reverse power (PRSM) under non-repetitive conditions with a 10 μs pulse width, as defined in Figure 5 of the datasheet. This rating reflects its ability to absorb high-energy ESD events without degradation, supporting long-term reliability in frequently handled interfaces.
