Product details
Overview
NNCD3.6D-T1-AT from Renesas Electronics is a 2-pin ESD noise clipping diode in Super Mini Mold package, rated for 200 mW power dissipation, with 3.40–3.80 V breakdown voltage (VBR), 130 Ω dynamic impedance (ZZ), and 30 kV IEC 1000-4-2 ESD endurance. It protects external interface circuits such as parallel printer ports and CD-ROM connectors against electrostatic discharge.
For engineers reviewing the NNCD3.6D-T1-AT datasheet, NNCD3.6D-T1-AT pinout, NNCD3.6D-T1-AT application, or NNCD3.6D-T1-AT equivalent, key selection criteria include clamping voltage, dynamic impedance, junction capacitance (210 pF), surge power rating (85 W at 10 µs), and compatibility with low-voltage logic interfaces requiring fast transient suppression.
Technical Context
This device operates as a bidirectional voltage-clamping diode optimized for IEC 1000-4-2 Level 4 ESD protection (±30 kV contact discharge). Its low dynamic impedance ensures rapid voltage clamping during transients, while its 210 pF junction capacitance balances signal integrity and protection strength for DC/low-speed digital lines.
The diode exhibits a typical forward voltage of 1.0 V at 5 mA test current and maintains stable breakdown behavior across ambient temperatures from –55 °C to +150 °C. Its thermal resistance profile supports operation up to 150 °C junction temperature under pulsed surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 3.40–3.80 V at 5 mA - defines minimum clamping threshold before conduction begins |
| Dynamic Impedance (ZZ) | 130 Ω max - determines voltage overshoot during ESD pulse (lower = tighter clamping) |
| Junction Capacitance (Ct) | 210 pF typ at 1 MHz, 1.0 V - impacts signal rise time on protected lines |
| ESD Withstand Voltage | ≥30 kV per IEC 1000-4-2 - validated for industrial-grade contact discharge immunity |
| Surge Reverse Power (PRSM) | 85 W at 10 µs pulse - supports single-event transient energy absorption |
| Power Dissipation (P) | 200 mW continuous - sets maximum steady-state thermal load on PCB layout |
| Junction Temperature (Tj) | 150 °C max - constrains thermal design margin for high-ambient applications |
Pinout & Package
Package: 2-pin Super Mini Mold (SMD), dimensions 2.5 ± 0.15 mm × 1.25 ± 0.1 mm × 0.9 ± 0.1 mm, cathode indicated by marking band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal for forward bias | Connected to protected line; conducts during positive ESD events |
| Cathode | Negative terminal with polarity marking | Connected to ground or reference rail; conducts during negative ESD events |
Key Features
| Feature | Design Value |
|---|---|
| IEC 1000-4-2 ESD rating | ≥30 kV contact discharge - meets industrial immunity requirements without external circuitry |
| Low dynamic impedance | 130 Ω max - limits clamped voltage to ≤3.8 V + (IESD × 130 Ω) during fast transients |
| Wide VBR range coverage | 3.3 V to 12 V family - enables precise matching to IC I/O voltage rails (e.g., 3.3 V, 5 V, 12 V) |
| 200 mW power rating | Supports continuous operation in compact SMD layouts with minimal copper area |
Applications
| Parallel Printer Interface Protection | CD-ROM Data Bus Protection |
|---|---|
Use Scenario: Protecting 8-bit parallel data lines between PC and legacy printers from user-handling ESD. IC Role / Device Role: Bidirectional clamping diode placed between each data line and chassis ground. Use Value: Prevents latch-up or damage to 3.3 V/5 V TTL-compatible port drivers during ±30 kV contact discharge events. | Use Scenario: Shielding ATAPI/IDE data bus signals (D0–D7, IORD#, IOWR#) in optical drive modules. IC Role / Device Role: Line-to-ground ESD suppressor on each signal trace near connector edge. Use Value: Maintains signal integrity with 210 pF capacitance while limiting transient overshoot to safe levels for IDE controller inputs. |
| Game Console Peripheral Port | Industrial Control Panel Keypad |
Use Scenario: Securing cartridge slot or controller port pins in consumer game hardware exposed to frequent insertion/removal. IC Role / Device Role: Low-capacitance ESD clamp on bidirectional address/data lines. Use Value: Enables reliable hot-plug operation without degrading 1–10 MHz signal timing due to 210 pF loading. | Use Scenario: Protecting membrane keypad scan lines in factory HMIs subject to operator static discharge.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Quad-channel, 5.5 V VBR, 12 pF per channel, SOT-563 package | Higher integration for multi-line protection; lower capacitance but higher VBR | Prefer when protecting ≥4 adjacent lines with tight capacitance budget (<15 pF) |
| Vishay ESDBLE5.0D1W | Single-channel, 5.0 V VBR, 15 pF, SOD-323 package, 30 kV IEC 1000-4-2 | Lower capacitance and same ESD rating, but higher clamping voltage | Choose for 5 V systems where sub-20 pF loading is critical and 5.0 V clamping is acceptable |
Compared with NNCD3.6D-T1-AT, NUP4105MR6T1G offers space savings and lower capacitance at the cost of fixed 5.5 V clamping and quad-channel rigidity, while ESDBLE5.0D1W trades 210 pF for 15 pF and higher VBR, making it suitable only where system voltage margins allow 5.0 V clamping.

FAQ
What is the maximum continuous power dissipation rating for NNCD3.6D-T1-AT?
NNCD3.6D-T1-AT has a maximum continuous power dissipation of 200 mW at TA = 25 °C. Derating is required above 25 °C ambient, following the curve in Figure 1 of the datasheet: power drops linearly to zero at 150 °C ambient. This rating governs PCB copper area and thermal relief design for sustained operation.
Does NNCD3.6D-T1-AT meet IEC 61000-4-2 Level 4 ESD immunity?
Yes, NNCD3.6D-T1-AT is specified to withstand ≥30 kV contact discharge per IEC 1000-4-2 (now IEC 61000-4-2), which corresponds to Level 4 - the highest severity level defined in the standard. This rating is verified per the test method in the original Renesas datasheet D11772EJ2V0DS00.
What is the junction capacitance of NNCD3.6D-T1-AT and how does it affect signal integrity?
NNCD3.6D-T1-AT has a typical junction capacitance of 210 pF at 1 MHz and 1.0 V reverse bias. This value limits use to DC and low-speed digital lines (e.g., parallel printer, keypad scan), as higher-frequency signals would experience excessive attenuation or timing skew. It is not suitable for USB 2.0 or HDMI interfaces.
Can NNCD3.6D-T1-AT be used in automotive applications?
NNCD3.6D-T1-AT is classified as "Standard" quality grade per Renesas documentation and is intended for computers, office equipment, and consumer electronics - not automotive systems. It lacks AEC-Q200 qualification and is not recommended for vehicle environments without additional validation and derating.
What is the cathode identification method on NNCD3.6D-T1-AT?
NNCD3.6D-T1-AT uses a cathode band marking on the package body, aligned with Pin 2 per the Super Mini Mold outline drawing. The band is visible as a distinct ink stripe or molded indentation, and must be oriented toward the ground/reference rail during PCB layout to ensure correct bidirectional clamping polarity.
