Product details
Overview
NNCD10D-T1-AT from Renesas Electronics is a 2-pin electrostatic discharge (ESD) noise clipping diode in Super Mini Mold package, rated for 200 mW power dissipation, with breakdown voltage 9.42–10.58 V, dynamic impedance ≤30 Ω at 5 mA, and ESD endurance ≥30 kV per IEC 1000-4-2. It protects external interface circuits such as parallel printer ports and CD-ROM connections against transient overvoltage.
For engineers reviewing the NNCD10D-T1-AT datasheet, NNCD10D-T1-AT pinout, NNCD10D-T1-AT application, or NNCD10D-T1-AT equivalent, key selection criteria include clamping voltage (7.0 V typ. at 1 A), junction capacitance (80 pF at 0 V), surge reverse power rating (85 W, 10 µs pulse), thermal resistance (625 °C/W), and compatibility with standard PCB mounting on glass epoxy substrates.
Technical Context
This device operates as a bidirectional voltage-clamping diode optimized for fast transient suppression in low-capacitance signal lines. Its design centers on low dynamic impedance (≤30 Ω) and tight breakdown voltage tolerance (±6%) to ensure consistent clamping behavior across production lots and temperature ranges.
It meets IEC 1000-4-2 Level 4 ESD immunity requirements without external biasing, relying solely on its intrinsic avalanche characteristics. The 2-pin configuration and unidirectional conduction path (cathode-marked) enable simple parallel placement across protected signal-to-ground paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 9.42–10.58 V at 5 mA - defines minimum trigger threshold for clamping action |
| Clamping Voltage | 7.0 V typical at 1 A - actual voltage seen by protected circuit during 30 kV ESD event |
| Junction Capacitance | 80 pF at 0 V - limits high-frequency signal distortion on data lines up to ~10 MHz |
| Dynamic Impedance | ≤30 Ω at 5 mA - ensures low-voltage overshoot during fast transients |
| Surge Power Rating | 85 W (10 µs pulse) - supports single-event ESD stress without degradation |
| Power Dissipation | 200 mW continuous - sets maximum steady-state thermal load on PCB layout |

Key Features
| Feature | Design Value |

Applications
| Parallel Printer Interface Protection | CD-ROM Data Line Clamping |
|---|---|
Use Scenario: Protects bi-directional data lines (e.g., STROBE, ACK, BUSY) between PC motherboard and parallel port peripherals against ESD events during cable hot-plug. IC Role / Device Role: Voltage-clamping diode placed between each signal line and chassis ground. Use Value: Prevents latch-up or gate oxide damage in legacy parallel port transceivers by limiting transient voltage to ≤7.0 V. | Use Scenario: Shields CD-ROM drive interface signals (e.g., DATA[7:0], IRQ) from ESD induced by user handling of audio/data cables. IC Role / Device Role: Unidirectional clamping diode connected anode-to-signal, cathode-to-ground. Use Value: Maintains <80 pF loading to avoid timing skew on 16-bit wide IDE-style data bursts. |
| Industrial Control Panel Keypad Lines | Legacy Game Console Peripheral Ports |
Use Scenario: Guards momentary switch matrix scan lines in factory HMIs exposed to operator touch-induced ESD. IC Role / Device Role: Low-leakage (<2 µA at 1 V) clamping diode on each row/column line. Use Value: Ensures reliable key detection by preventing false triggers caused by >15 kV air discharge coupling into traces. | Use Scenario: Suppresses ESD on controller port pins (e.g., NES, SNES expansion connectors) during cartridge insertion/removal. IC Role / Device Role: Standalone transient suppressor mounted directly at connector footprint. Use Value: Eliminates need for series resistors or RC filters that would degrade 1–2 MHz digital handshake timing. |
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 SOT-23, 12 V breakdown, 120 pF capacitance, 30 kV ESD rating | Integrated 4-line protection vs. discrete single-line; higher capacitance limits speed | Preferred when protecting multiple adjacent lines with shared ground and space-constrained layout |
| Vishay SMAJ10A | DO-214AC package, 10 V standoff, 100 W surge rating, 100 pF capacitance | Larger footprint, higher clamping voltage (17.5 V), intended for power rail vs. signal line protection | Suitable only for non-data-line applications where 100 pF and 17.5 V clamping are acceptable |
Compared with NNCD10D-T1-AT, the NUP4105MR6T1G offers integration but sacrifices bandwidth due to higher capacitance, while the SMAJ10A trades compact size and low clamping for reduced signal integrity - making NNCD10D-T1-AT optimal for discrete, high-speed, low-capacitance interface protection.

FAQ
What is the maximum continuous power dissipation rating for NNCD10D-T1-AT?
The NNCD10D-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 - e.g., ~100 mW at 75 °C ambient. This rating assumes mounting on a standard 30 × 30 × 1.6 mm glass epoxy PCB with no additional copper pour.
Does NNCD10D-T1-AT meet IEC 61000-4-2 Level 4 ESD immunity?
Yes, the NNCD10D-T1-AT is specified to withstand ≥30 kV contact discharge per IEC 1000-4-2 (now superseded as IEC 61000-4-2), which exceeds Level 4 (8 kV contact / 15 kV air) requirements. This performance is validated under single-pulse conditions with 150 pF/330 Ω network, as documented in the Electrical Characteristics table.
What is the typical clamping voltage of NNCD10D-T1-AT at 1 A transient current?
The typical clamping voltage of NNCD10D-T1-AT is 7.0 V at 1 A, measured under standardized ESD pulse conditions (150 pF/330 Ω). This value appears in the "E.S.D Voltage" column of the datasheet's Electrical Characteristics table and represents the peak voltage observed across the diode during a full 30 kV ESD event.
Can NNCD10D-T1-AT be used for bidirectional signal line protection?
No - the NNCD10D-T1-AT is a unidirectional diode with cathode marking. For bidirectional protection (e.g., USB D+, D−), two devices must be used in series opposition or a dedicated bidirectional TVS like the PESD5V0S1BA should be selected. The NNCD10D-T1-AT conducts only when anode is positive relative to cathode.
What is the junction capacitance of NNCD10D-T1-AT and how does it affect signal integrity?
The NNCD10D-T1-AT exhibits 80 pF typical junction capacitance at 0 V bias. This value limits usable bandwidth: for a 50 Ω transmission line, it introduces ~6 ns rise-time degradation, making the device suitable for parallel bus speeds ≤10 Mbps but unsuitable for USB 2.0 or HDMI interfaces where sub-2 pF is required.
