Product details
Overview
NNCD36DT-T1-AT from Renesas Electronics is an ESD noise clipping diode designed for bidirectional transient suppression on LIN bus lines, featuring a 33–39 V breakdown voltage (VBR), 9 pF typical capacitance at 1 MHz, 85 W surge reverse power rating (tT = 10 μs), 200 mW power dissipation, and compliance with IEC61000-4-2 ESD immunity standards.
For engineers reviewing the NNCD36DT-T1-AT datasheet, NNCD36DT-T1-AT pinout, NNCD36DT-T1-AT application, or NNCD36DT-T1-AT equivalent, this device serves as a dedicated, low-capacitance, surface-mount protection solution for automotive LIN physical layer interfaces requiring robust ±15 kV contact/±20 kV air ESD clamping performance without signal integrity degradation.
Technical Context
The NNCD36DT-T1-AT operates as a bidirectional avalanche diode, clamping both positive and negative transients above its specified VBR range (33–39 V) while maintaining sub-0.1 μA reverse leakage at 27 V. Its low 9 pF junction capacitance minimizes signal distortion on 19.2–20 kbps LIN bus waveforms.
It is rated for 85 W non-repetitive surge power under 10 μs pulses and dissipates up to 200 mW continuously when mounted on a standard 50 mm × 50 mm × 1.6 mm FR-4 PCB. Thermal impedance drops from 625°C/W at 1 ms to ~10°C/W at 100 ms, supporting short-duration ESD event handling.
Key Specifications

|---|---|
| Breakdown Voltage (VBR) | 33–39 V at 2 mA - defines clamping threshold for LIN bus overvoltage events |
| Junction Capacitance (Ct) | 9 pF at 0 V, 1 MHz - ensures minimal loading on LIN differential signaling |
| Surge Reverse Power (PRSM) | 85 W (10 μs pulse) - withstands IEC61000-4-2 Level 4 ESD strikes |
| Power Dissipation (P) | 200 mW - supports continuous operation on standard FR-4 PCB layout |
| ESD Withstand Voltage | ±15 kV contact, ±20 kV air per IEC61000-4-2 - meets automotive LIN ESD requirements |

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 VBR (5.5 V), higher Ct (11 pF), same SC-70 package | Targeted for USB/low-voltage data lines, not LIN-rated | Not suitable for 12 V automotive LIN; insufficient clamping headroom |
| ESDALC6V1-1U2 | Higher VBR (6.1 V), lower Ct (0.9 pF), SOD-523 package | Designed for high-speed digital interfaces (USB 2.0, HDMI), not automotive ESD standards | Too low VBR for LIN bus; fails to clamp at required voltage level |
Compared with TPD2E001DRYR and ESDALC6V1-1U2, the NNCD36DT-T1-AT provides the only validated 33–39 V bidirectional clamping window matched to LIN bus operating margins and certified IEC61000-4-2 performance - making it the sole drop-in solution for production automotive LIN node protection.

FAQ
What is the primary function of the NNCD36DT-T1-AT?
The NNCD36DT-T1-AT functions as a bidirectional ESD noise clipping diode optimized for LIN bus protection. It clamps transient voltages above 33–39 V in both polarities, absorbs ±15 kV contact ESD per IEC61000-4-2, and maintains only 9 pF capacitance to avoid distorting the 19.2 kbps LIN signal. Its design ensures reliable operation in automotive body electronics where space and signal fidelity are critical.
Does the NNCD36DT-T1-AT require orientation during PCB placement?
No - the NNCD36DT-T1-AT is a symmetrical, bidirectional device with identical electrical behavior on both pins, so orientation does not affect clamping performance. Pins 1 and 2 are interchangeable in circuit layout, simplifying automated placement and reducing assembly errors. This symmetry is confirmed by its dual-anode/cathode structure and identical VBR specification for both polarities.
What is the maximum continuous power dissipation for NNCD36DT-T1-AT?
The NNCD36DT-T1-AT has a maximum continuous power dissipation of 200 mW when mounted on a standard 50 mm × 50 mm × 1.6 mm FR-4 PCB, as defined in its Absolute Maximum Ratings table. This rating assumes natural convection cooling and applies at 25°C ambient; derating is required above 25°C per the thermal curve in Figure 1 of the datasheet. It is not intended for sustained power regulation.
Is NNCD36DT-T1-AT compliant with automotive ESD standards?
Yes - the NNCD36DT-T1-AT is explicitly designed and tested to comply with IEC61000-4-2 Level 4 (±15 kV contact, ±20 kV air), which aligns with automotive system-level ESD requirements for LIN bus interfaces. Its 85 W surge power rating at 10 μs and 33–39 V breakdown window ensure robust protection against real-world electrostatic discharge events encountered during vehicle manufacturing and service.
What package type does NNCD36DT-T1-AT use, and is it RoHS-compliant?
NNCD36DT-T1-AT uses the 2-pin Super Mini Mold (SC-76) package, measuring 2.5 × 1.7 × 0.9 mm, with pure Sn (tin) lead plating and Pb-free construction throughout the external electrodes and internal structure. It meets RoHS Directive 2011/65/EU requirements, as confirmed in the ordering information section of the D18880EJ1V0DS00 datasheet.
