Product details
Overview
NNCD6.2LG(1)-T1-A from Renesas Electronics is a low-capacitance quad ESD protection diode in a 5-pin mini mold package with common-anode configuration. It delivers 5.7–6.7 V breakdown voltage, ≤8 Ω dynamic impedance, ≤2 µA reverse leakage at 3.0 V, 8 pF capacitance at 1 MHz, and 8 kV IEC 1000-4-2 contact discharge ESD immunity - optimized for USB 2.0 data line protection.
For engineers reviewing the NNCD6.2LG(1)-T1-A datasheet, NNCD6.2LG(1)-T1-A pinout, NNCD6.2LG(1)-T1-A application, or NNCD6.2LG(1)-T1-A equivalent, key selection criteria include low inter-electrode capacitance, guaranteed 8 kV ESD robustness, common-anode quad topology for bidirectional signal line clamping, and compatibility with high-density PCB layouts requiring compact 5-pin surface-mount packaging.
Technical Context
This device implements four identical silicon avalanche diodes connected in a common-anode (quarto) configuration, enabling simultaneous clamping of four independent signal lines to ground during ESD transients. Each cathode-anode path exhibits sharp, repeatable breakdown at 5.7–6.7 V with sub-8 Ω dynamic impedance under 5 mA test current.
Designed specifically for I/O line protection in high-speed digital interfaces, it maintains signal integrity via 8 pF terminal-to-terminal capacitance (measured at VR = 0 V, f = 1 MHz) and supports transient surge power dissipation up to 2 W for 10 µs pulses without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 5.7–6.7 V min/max at 5 mA - defines precise clamping threshold before conduction begins on each cathode-anode path. |
| Dynamic Impedance (ZZ) | ≤50 Ω max at 5 mA - ensures low-voltage overshoot during fast ESD events by limiting clamping voltage rise. |
| Reverse Leakage (IR) | ≤2 µA max at 3.0 V - minimizes standby current draw and prevents signal distortion on idle data lines. |
| Capacitance (Ct) | 8 pF typ at VR = 0 V, f = 1 MHz - preserves USB 2.0 signal edge rates and eye diagram integrity. |
| ESD Withstand (IEC 1000-4-2) | 8 kV contact discharge - meets industrial-grade interface immunity requirements without external circuitry. |
| Package | 5-pin mini mold - enables 2.8 × 2.9 mm footprint with 0.65 mm pitch for space-constrained USB port routing. |
Pinout & Package
Supplied in a surface-mount 5-pin mini mold package (2.8 mm × 2.9 mm × 1.1–1.4 mm height) with gull-wing leads and JEDEC-standard thermal pad exposure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 (K1) | ESD clamp node for first protected signal line (e.g., USB D+) |
| 2 | Anode (A, Common) | Shared anode tied to system ground - forms single-point return path for all four clamps |
| 3 | Cathode 2 (K2) | ESD clamp node for second protected signal line (e.g., USB D−) |
| 4 | Cathode 3 (K3) | ESD clamp node for third signal line (e.g., VBUS sense or ID line) |
| 5 | Cathode 4 (K4) | ESD clamp node for fourth signal line (e.g., shield or auxiliary control) |
Key Features
| Feature | Design Value |
|---|---|
| Quad common-anode topology | Enables compact protection of four independent signal paths using one ground connection and minimal board area. |
| 8 kV IEC 1000-4-2 contact discharge rating | Guarantees reliable operation in real-world handling environments without derating or additional TVS stages. |
| 8 pF inter-terminal capacitance | Preserves signal bandwidth up to ~200 MHz - suitable for full-speed USB 2.0 (480 Mbps) without jitter penalty. |
| 2 W surge power capability (10 µs pulse) | Handles multiple ESD strikes without parametric shift or catastrophic failure under typical interface stress conditions. |
Applications
| USB 2.0 Interface Protection | Industrial Serial Port ESD Guard |
|---|---|
Use Scenario: Protecting D+/D− differential pair and VBUS/ID lines on embedded USB host/device ports exposed to frequent human contact. IC Role / Device Role / Timing Role: Low-capacitance bidirectional transient voltage suppressor placed directly at connector entry point. Use Value: Prevents latch-up and gate oxide damage in USB transceivers while maintaining <1% signal attenuation at 240 MHz. | Use Scenario: Safeguarding RS-232/RS-485 transceiver I/O pins in factory automation panels subject to maintenance technician ESD events. IC Role / Device Role / Timing Role: Standalone ESD shunt clamp with grounded common anode, installed before level-shifting circuitry.

| Consumer Audio Docking Station | Medical Data Acquisition Module |
Use Scenario: Shielding audio sync and control lines (e.g., I²C, USB ID) in smartphone docking cradles where repeated plug/unplug causes charge accumulation. IC Role / Device Role / Timing Role: Quad-channel ESD absorber with shared ground reference to minimize ground bounce during multi-line discharge.

IC Role / Device Role / Timing Role: Non-intrusive ESD front-end guard that adds no propagation delay to time-critical sensor data streams. Use Value: Ensures uninterrupted 12-bit ADC sampling during electrostatic discharge - avoids false alarm triggers or missed vital signs. |
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 capacitance (3 pF), dual-channel only, requires separate ground connections per channel. | Limited to two-line protection; unsuitable for 4-signal USB layouts without duplication. | Select when ultra-low capacitance is prioritized over channel count and board area. |
| ESD5V3U2U-2/TR | Higher capacitance (12 pF), same 5-pin quarto package, 12 kV ESD rating but higher leakage (5 µA). | Better surge margin but degrades USB signal integrity above 120 MHz; not recommended for full-speed USB. | Prefer for industrial RS-485 nodes where ESD margin outweighs bandwidth constraints. |
Compared with TPD2E001DRYR and ESD5V3U2U-2/TR, NNCD6.2LG(1)-T1-A uniquely balances 4-channel integration, 8 pF capacitance, and guaranteed 8 kV immunity in a single 5-pin footprint - making it optimal for space-constrained USB 2.0 designs requiring deterministic clamping behavior without signal degradation.

FAQ
What is the maximum operating temperature for NNCD6.2LG(1)-T1-A?
The NNCD6.2LG(1)-T1-A has a specified junction temperature limit of 150°C and a storage temperature range of –55°C to +150°C. Its thermal resistance allows continuous operation at ambient temperatures up to 125°C when mounted on standard FR-4 PCBs with adequate copper pour, as confirmed by the transient thermal impedance curve in the original Renesas datasheet D12785EJ1V0DS00.
Does NNCD6.2LG(1)-T1-A support both contact and air-gap ESD testing per IEC 1000-4-2?
Yes, the NNCD6.2LG(1)-T1-A is rated for 8 kV contact discharge per IEC 1000-4-2. While the datasheet specifies contact discharge performance explicitly, air-gap testing is not characterized for this part - design validation for air-gap scenarios should be performed empirically or with higher-rated alternatives if required.
Can NNCD6.2LG(1)-T1-A be used for HDMI or PCIe signal line protection?
No, NNCD6.2LG(1)-T1-A is not recommended for HDMI or PCIe. Its 8 pF capacitance exceeds the ≤0.5 pF requirement for HDMI 2.0 and PCIe Gen3 signal integrity, and its 5.7–6.7 V breakdown voltage is incompatible with the 0–3.3 V common-mode swing of those interfaces. It is validated only for USB 2.0 and similar lower-bandwidth buses.
Is the common anode of NNCD6.2LG(1)-T1-A internally bonded or externally accessible?
The common anode of NNCD6.2LG(1)-T1-A is externally accessible at Pin 2, as shown in the official pin connection diagram. This allows direct connection to system ground plane or local low-inductance ground pour - essential for achieving the specified 8 kV ESD performance and minimizing ground loop impedance during transient events.
What is the surge power rating of NNCD6.2LG(1)-T1-A and how is it applied?
NNCD6.2LG(1)-T1-A supports 2 W surge reverse power for 10 µs pulses (single event), as defined in Figure 5 of the Renesas datasheet D12785EJ1V0DS00. This rating applies across all four cathode-anode paths simultaneously when the common anode is properly grounded, enabling robust protection against repetitive ESD strikes without parameter drift or thermal runaway.
