Product details
Overview
NNCD36DA-T1-AT from Renesas Electronics is a 2-pin SC-76 packaged ESD noise clipping diode with a breakdown voltage of 34.0–38.0 V, dynamic impedance ≤90 Ω at 2 mA, and 22 pF capacitance at 0 V/1 MHz. It delivers 20 kV ESD protection per IEC61000-4-2 and handles 85 W surge reverse power (10 μs pulse), designed for high-speed data line protection in USB, HDMI, and audio interfaces.
For engineers reviewing the NNCD36DA-T1-AT datasheet, NNCD36DA-T1-AT pinout, NNCD36DA-T1-AT application, or NNCD36DA-T1-AT equivalent, this page provides verified electrical specs, package dimensions, real-world interface protection use cases, and two validated alternative parts with documented parameter differences.
Technical Context
The NNCD36DA-T1-AT operates as a unidirectional transient voltage suppression diode optimized for electrostatic discharge clamping on signal lines. Its low 22 pF capacitance minimizes signal integrity impact on high-frequency interfaces, while its 34–38 V breakdown range targets protection of 3.3 V and 5 V logic rails against ±20 kV contact discharge events.
It uses a planar silicon junction structure in a 2-pin Super Mini Mold (SC-76) package with cathode marking, enabling surface-mount integration into compact external interface circuits. Thermal performance is characterized by transient thermal impedance curves supporting short-pulse energy absorption without junction overheating.

Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 ports against ESD events during cable insertion/removal. IC Role / Device Role / Timing Role: Clamping diode placed between signal line and ground to divert ESD current away from USB transceiver IC. Use Value: 22 pF capacitance avoids signal rise-time degradation; ±20 kV rating exceeds USB-IF compliance requirement of ±15 kV. | Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) line from user-induced static discharge when connecting displays. IC Role / Device Role / Timing Role: Unidirectional shunt device connected between HPD pin and chassis ground to clamp transients before reaching HDMI controller. Use Value: 34–38 V breakdown aligns with HPD logic-high voltage (typically 3.3–5 V), preventing false disconnect detection during clamping. |
| Audio Line Inputs | Industrial RS-485 Transceivers |
Use Scenario: Shielding analog audio inputs (e.g., 3.5 mm jack) in portable speakers or docking stations from ESD during headphone plugging. IC Role / Device Role / Timing Role: Low-capacitance clamp on line driver output to preserve audio bandwidth and prevent pop/noise injection. Use Value: 22 pF capacitance maintains flat frequency response up to 20 kHz; 200 mW power rating supports sustained line-level operation. | Use Scenario: Protecting RS-485 differential bus lines (A/B) in factory automation controllers exposed to maintenance personnel ESD. IC Role / Device Role / Timing Role: Paired diodes (one per line) referenced to common ground to suppress common-mode transients on twisted-pair cabling. Use Value: 85 W surge capability handles multiple ESD strikes; SC-76 footprint allows dual-diode layout within tight board space constraints. |
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 15 pF capacitance; 3.6 V breakdown; dual-channel in SOT-553 | Better suited for high-speed USB 3.0 or MIPI lines; not rated for >15 kV ESD | Select for <5 Gbps interfaces where lower capacitance is critical; verify system-level ESD test pass with actual layout |
| ESD9X3.3SCT5G | 3.3 V breakdown; 12 pF capacitance; 12 kV IEC61000-4-2 rating | Optimized for 3.3 V logic rails; insufficient for 36 V clamping requirement of NNCD36DA-T1-AT | Choose only for low-voltage I/O protection; cannot substitute in 24–48 V industrial signal line applications |
Compared with TPD2E001DRYR and ESD9X3.3SCT5G, the NNCD36DA-T1-AT uniquely balances high-voltage clamping (34–38 V), moderate capacitance (22 pF), and industrial-grade ±20 kV ESD tolerance-making it suitable for legacy and mixed-voltage interface protection where higher breakdown and proven reliability are required.

FAQ
What is the primary function of the NNCD36DA-T1-AT?
The NNCD36DA-T1-AT is a unidirectional ESD protection diode engineered to clamp electrostatic discharge transients on signal lines. Its 34–38 V breakdown voltage and ±20 kV IEC61000-4-2 rating make the NNCD36DA-T1-AT ideal for safeguarding 3.3 V and 5 V interface circuits such as USB, HDMI, and RS-485 from damage caused by human-body-model ESD events.
Does the NNCD36DA-T1-AT support bidirectional ESD protection?
No, the NNCD36DA-T1-AT is a unidirectional diode configured for clamping positive transients to ground. It does not provide symmetrical protection for both polarities. For bidirectional applications, two NNCD36DA-T1-AT devices must be used in series opposition or a dedicated bidirectional TVS array should be selected instead of relying solely on the NNCD36DA-T1-AT.
What is the maximum operating temperature for the NNCD36DA-T1-AT?
The NNCD36DA-T1-AT has a specified storage temperature range of −55 to +150°C and a maximum junction temperature of +150°C. When mounted on a standard 30 mm × 30 mm × 1.6 mm FR-4 PCB, its power dissipation remains within 200 mW up to an ambient temperature of 125°C-confirming the NNCD36DA-T1-AT's suitability for under-hood automotive and industrial control environments.
Is the NNCD36DA-T1-AT RoHS-compliant?
Yes, the NNCD36DA-T1-AT features pure tin (Sn) lead plating and contains no lead in external electrodes or other parts, satisfying RoHS Directive 2011/65/EU requirements. This compliance is explicitly stated in the original NEC Electronics ordering information and confirmed in Renesas' post-merger documentation for the NNCD series.
Can the NNCD36DA-T1-AT be used for surge protection beyond ESD events?
The NNCD36DA-T1-AT is rated for 85 W surge reverse power at 10 μs pulse width, making it suitable for single-event ESD and minor lightning-induced surges on low-energy signal lines. However, it is not designed for AC line surges or repetitive high-energy transients. For sustained surge protection, the NNCD36DA-T1-AT must be paired with upstream current-limiting resistors or used alongside dedicated MOVs or GDTs-not deployed alone as primary AC mains protection.
