Product details
Overview
NNCD8.2J-T1-A from Renesas Electronics is an ESD noise clipping diode designed for IEC 61000-4-2 Level 4 (±30 kV contact discharge) protection in external interface circuits. It features a breakdown voltage of 7.7–8.7 V at 5 mA, 70 pF capacitance at 1 MHz and 0 V bias, 5 µA max reverse leakage at 2 V, 150 mW power dissipation, and ultra-super-mini flat mold (2-pin) packaging. It is used in USB, audio jack, and keypad interface surge suppression.
For engineers reviewing the NNCD8.2J-T1-A datasheet, NNCD8.2J-T1-A pinout, NNCD8.2J-T1-A application, or NNCD8.2J-T1-A equivalent, key selection criteria include verified IEC 61000-4-2 contact ESD endurance (±30 kV), low clamping capacitance (<75 pF), tight VBR tolerance (±0.5 V), thermal performance under transient pulse (t = 10 µs), and compatibility with high-density automated assembly on consumer-grade PCBs.
Technical Context
This device operates as a unidirectional silicon planar junction diode optimized for fast transient voltage clamping. Its low dynamic impedance below 1 Ω during ESD events enables rapid voltage limiting to protect downstream ICs. The flat 2-pin package supports <0.6 mm profile mounting and reflow-compatible soldering.
The diode exhibits stable breakdown behavior with minimal variation across temperature (−55°C to +150°C storage, 150°C max junction). Its 85 W non-repetitive surge power rating at t = 10 µs aligns with IEC 61000-4-2 waveform requirements, and its 70 pF capacitance ensures minimal signal distortion in 10–100 MHz interface paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 7.7–8.7 V at 5 mA - defines precise clamping threshold for ±30 kV ESD events without false triggering. |
| Capacitance | 70 pF at 1 MHz, 0 V - low enough to avoid signal integrity degradation in USB 2.0 or audio line applications. |
| Reverse Leakage | ≤5 µA at 2 V - ensures negligible standby current in battery-powered interfaces. |
| ESD Withstand | ±30 kV contact discharge per IEC 61000-4-2 - validated immunity level for industrial and consumer port protection. |
| Power Dissipation | 150 mW continuous - supports sustained operation in ambient temperatures up to +125°C with derating. |
| Surge Power | 85 W at t = 10 µs - matches peak energy of IEC 61000-4-2 test pulse without thermal runaway. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9X8.2SFT5G | Lower capacitance (30 pF), higher leakage (10 µA), SOD-923 package (1.0 × 0.6 mm) | Better for RF/analog lines; less suitable for low-power battery systems due to doubled IR | Choose when signal bandwidth >200 MHz and leakage budget allows ≥10 µA. |
| TPD2E001DRYR | Dual-channel, 12 pF per line, integrated 5 V TVS, X2SON package (1.0 × 0.6 mm) | Requires dual-line protection; adds layout complexity but reduces BOM count for differential pairs | Prefer for space-constrained USB Type-C or MIPI D-PHY interfaces needing matched pair clamping. |
Compared with ESD9X8.2SFT5G and TPD2E001DRYR, the NNCD8.2J-T1-A offers tighter VBR tolerance (±0.5 V vs. ±1.0 V), lower cost per channel, and proven reliability in high-cycle consumer interfaces-making it optimal for single-line, cost-sensitive, high-volume applications where 70 pF capacitance is acceptable.

FAQ
What is the maximum ESD voltage level the NNCD8.2J-T1-A can withstand?
The NNCD8.2J-T1-A is rated for ±30 kV contact discharge per IEC 61000-4-2, verified in production testing. This represents the highest severity level defined in the standard and confirms robust protection for user-accessible ports. Each unit of NNCD8.2J-T1-A undergoes screening to ensure consistent clamping behavior across this stress level without parametric shift or failure.
Does the NNCD8.2J-T1-A require a series resistor for optimal ESD protection?
No series resistor is required for basic ESD clamping functionality of the NNCD8.2J-T1-A, as its low dynamic impedance (<1 Ω) enables direct shunting of transient current. However, a 10–100 Ω resistor may be added upstream to limit peak current in extreme multi-pulse scenarios or to reduce ringing-designs using NNCD8.2J-T1-A should validate signal integrity with and without such resistors per actual trace length and load.
Is the NNCD8.2J-T1-A RoHS compliant and lead-free?
Yes, the NNCD8.2J-T1-A meets EU RoHS Directive 2011/65/EU requirements and is manufactured with lead-free terminations compatible with standard SnAgCu reflow profiles. Renesas confirms full compliance in its material declarations, and the NNCD8.2J-T1-A carries the appropriate marking per JEDEC J-STD-609. No exemptions apply.
Can the NNCD8.2J-T1-A be used in bidirectional signal lines?
The NNCD8.2J-T1-A is a unidirectional diode and must be used with cathode tied to ground to protect positive transients. For true bidirectional protection (e.g., RS-485, CAN), two NNCD8.2J-T1-A units in back-to-back configuration-or a dedicated bidirectional device-are required. Using a single NNCD8.2J-T1-A on a floating line will not suppress negative-going surges.
What is the thermal resistance (RθJA) of the NNCD8.2J-T1-A in standard PCB layout?
The NNCD8.2J-T1-A does not specify RθJA in its datasheet, but transient thermal impedance data shows Zth = 833°C/W at t = 10 µs on a ceramic board (10 × 7.5 × 0.75 mm, Cu film 11 × 2 × 0.035 mm). In typical FR-4 layouts with 1 cm² copper pour, effective RθJA is ~350°C/W. Derating curves confirm 150 mW continuous dissipation is safe up to +100°C ambient when mounted per recommended land pattern.
