Product details
Overview
NNCD36J-T1-AT from Renesas Electronics is an ESD noise clipping diode designed for electrostatic discharge protection in external interface circuits. It features a breakdown voltage of 34.0–38.0 V (min/max), 15 pF capacitance at 0 V, 2 µA max reverse leakage at 27 V, 12 kV IEC 61000-4-2 contact ESD rating, and 150 mW power dissipation in a 2-pin ultra-super-mini mold flat package.
For engineers reviewing the NNCD36J-T1-AT datasheet, NNCD36J-T1-AT pinout, NNCD36J-T1-AT application, or NNCD36J-T1-AT equivalent, key selection criteria include its high-voltage ESD clamping capability, low capacitance for signal integrity preservation, compact surface-mount footprint, and suitability for USB, HDMI, and other high-speed port protection where transient immunity and minimal parasitic loading are critical.
Technical Context
This diode operates as a unidirectional voltage-clamping device with avalanche breakdown behavior, triggered by fast-rising ESD transients per IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact). Its 34–38 V breakdown range ensures reliable clamping above normal operating voltages while protecting downstream ICs rated up to 30 V.
The 15 pF capacitance at 0 V and low 2 µA leakage at VR = 27 V enable integration into high-speed digital interfaces without degrading signal rise/fall times or increasing standby current. Thermal performance is defined by a 833°C/W transient thermal impedance and 150 mW steady-state power limit at 25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 34.0–38.0 V - Clamps transients above system rail voltage while avoiding false triggering during normal operation. |
| Capacitance (Ct) | 15 pF at 0 V - Minimizes signal distortion on high-speed lines such as USB 2.0 or LVDS. |
| Reverse Leakage (IR) | ≤2 µA at 27 V - Ensures negligible standby current draw in battery-powered or low-power systems. |
| ESD Withstand | 12 kV contact per IEC 61000-4-2 - Meets industrial-grade ESD immunity requirements for external ports. |
| Power Dissipation | 150 mW - Supports continuous operation within thermal limits on standard FR-4 PCBs with typical copper area. |
| Surge Power (PRSM) | 85 W (10 µs pulse) - Handles single-event ESD surges without degradation or failure. |
Pinout & Package

Applications
| USB 2.0 Port Protection | HDMI Interface Protection |
|---|---|
Use Scenario: Protecting USB 2.0 D+ and D− lines from user-handling ESD events in peripheral devices. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between signal line and ground to shunt ESD current before it reaches the USB transceiver. Use Value: 15 pF capacitance avoids signal integrity loss at 480 Mbps; 12 kV contact rating exceeds USB-IF ESD requirements. | Use Scenario: Safeguarding HDMI TMDS differential pairs against ESD during cable insertion/removal in AV receivers and displays. IC Role / Device Role / Timing Role: Low-capacitance clamp on each TMDS+ and TMDS− line referenced to chassis ground. Use Value: 34–38 V breakdown avoids interference with 3.3 V TMDS common-mode swing while clamping >8 kV transients. |
| Industrial Serial Interface (RS-485) | Automotive Infotainment I/O |
Use Scenario: ESD protection for RS-485 transceiver A/B lines in factory automation controllers exposed to harsh environments. IC Role / Device Role / Timing Role: Bidirectional protection implemented using two NNCD36J-T1-AT diodes (anode-to-line, cathode-to-ground and cathode-to-line, anode-to-ground). Use Value: 85 W surge rating handles repeated ESD exposure; 150 mW power dissipation allows sustained operation under thermal stress. | Use Scenario: Protecting auxiliary analog/digital I/O pins (e.g., AUX-IN, SD card slot) in automotive head units subject to human-body-model ESD. IC Role / Device Role / Timing Role: Standalone ESD clamp on low-speed signal paths where integrated protection is absent or insufficient. Use Value: "Standard" quality grade aligns with non-safety-critical infotainment functions; RoHS-compliant packaging meets automotive supply chain requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9X3.3SFT5G | Lower breakdown (3.3 V), higher capacitance (30 pF), same 2-pin SOD-523 package. | Designed for 3.3 V logic rails; unsuitable for 24–36 V signal lines. | Select only when protecting sub-5 V interfaces; NNCD36J-T1-AT remains required for higher-voltage clamping. |
| TPD2E001DRYR | Dual-channel, 15 pF/channel, 12 kV ESD rating, but 5 V breakdown and 0.65 mm × 0.65 mm X2SON package. | Optimized for space-constrained dual-line protection; not rated for >5.5 V operation. | Prefer for dual-line applications like I²C; NNCD36J-T1-AT offers superior voltage margin for legacy or mixed-voltage systems. |
Compared with ESD9X3.3SFT5G and TPD2E001DRYR, the NNCD36J-T1-AT delivers uniquely high-voltage clamping (34–38 V) with low 15 pF capacitance-making it the only viable option among the three for protecting 24–36 V industrial I/O, legacy RS-485, or high-side analog sensor lines without compromising signal fidelity or surge margin.

FAQ
What is the maximum operating temperature for NNCD36J-T1-AT?
The NNCD36J-T1-AT has a maximum junction temperature of 150°C and a storage temperature range of −55°C to +150°C. Its power derating curve shows usable dissipation down to ~80 mW at 100°C ambient, making it suitable for enclosed industrial enclosures without forced cooling. Always verify thermal layout with the 833°C/W transient thermal impedance data in the datasheet.
Does NNCD36J-T1-AT meet RoHS requirements?
Yes, NNCD36J-T1-AT complies with EU RoHS Directive restrictions on hazardous substances. Renesas Electronics confirms RoHS compliance for this part in the official product documentation and material declarations. No lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE substances exceed allowable thresholds.
Can NNCD36J-T1-AT be used for bidirectional ESD protection?
Yes, NNCD36J-T1-AT can be configured for bidirectional protection by pairing two units-anode-to-line/cathode-to-ground and cathode-to-line/anode-to-ground-creating symmetrical clamping around 0 V. This configuration is validated in Renesas application guidance for RS-485 and CAN bus protection where ±15 kV air discharge immunity is required.
What is the typical capacitance vs. reverse voltage behavior of NNCD36J-T1-AT?
Per the datasheet's Figure 3, NNCD36J-T1-AT exhibits 15 pF at 0 V, decreasing to ~5 pF at 27 V reverse bias. This voltage-dependent capacitance profile ensures minimal loading during normal operation while maintaining effective clamping near breakdown-critical for preserving edge rates on fast digital signals.
Is NNCD36J-T1-AT qualified for automotive applications?
NNCD36J-T1-AT carries a "Standard" quality grade per Renesas classification, intended for office equipment, communications gear, and industrial robots-not automotive safety-critical systems. For AEC-Q200 qualified alternatives, consult Renesas' dedicated automotive ESD portfolio; NNCD36J-T1-AT may be used in non-safety infotainment I/O with customer risk assessment.
