Product details
Overview
NNCD6.8MG-T1-A from Renesas Electronics is a low-capacitance, quad-channel ESD protection diode in SC-74A (5-pin Mini Mold) package with common-anode configuration. It delivers 6.2–7.1 V breakdown voltage, ≤30 Ω dynamic impedance at 5 mA, ≤2 µA reverse leakage at 3.5 V, 20 pF typical capacitance at 1 MHz/0 V, and withstands ≥30 kV per IEC61000-4-2 for USB interface line protection.
For engineers reviewing the NNCD6.8MG-T1-A datasheet, NNCD6.8MG-T1-A pinout, NNCD6.8MG-T1-A application, or NNCD6.8MG-T1-A equivalent, key selection criteria include its 20 pF capacitance, 30 kV ESD rating, common-anode quad-cathode topology, SC-74A footprint, and suitability for high-speed data lines where signal integrity and transient immunity are critical.
Technical Context
This device implements four independent Zener-clamping diodes sharing a single anode terminal, enabling simultaneous protection of four signal lines against electrostatic discharge. Its low 20 pF junction capacitance minimizes signal distortion on USB 1.1/2.0 differential pairs and other high-speed interfaces up to ~500 Mbps.
The diode operates via avalanche breakdown above 6.2 V, clamping transients to safe levels while maintaining <2 µA leakage below 3.5 V. Thermal design relies on PCB copper area (30×30×1.6 mm glass epoxy) to sustain 200 mW total dissipation and handle 2 W surge pulses (10 µs).

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DRYR (Texas Instruments) | Lower 0.75 pF capacitance; 12 kV IEC61000-4-2 rating; same SC-70-6 footprint but different pinout (no common anode) | Better for >1 Gbps interfaces (PCIe, SATA); insufficient for 30 kV industrial ESD requirements | Select when ultra-low capacitance outweighs ESD rating; requires PCB redesign due to non-common-anode layout |
| ESD5Z6.8T1G (ON Semiconductor) | Single-channel, 6.8 V Zener; 25 pF capacitance; SOD-523 package; 12 kV rating | Requires four devices for quad-line protection; increases layout area and solder joints | Choose only if supply chain constraints preclude NNCD6.8MG-T1-A; expect 3× higher assembly cost and test risk |
Compared with TPD4E001DRYR and ESD5Z6.8T1G, the NNCD6.8MG-T1-A uniquely combines 30 kV ESD immunity, quad-channel integration, and 20 pF capacitance in a single SC-74A package-making it optimal for cost-sensitive, space-constrained USB/HDMI designs requiring industrial-grade robustness without sacrificing signal fidelity.

FAQ
What is the maximum operating temperature for the NNCD6.8MG-T1-A?
The NNCD6.8MG-T1-A has a maximum junction temperature of 150°C and a storage temperature range of −55°C to +150°C. Its thermal performance depends on PCB copper area; with a 30×30×1.6 mm glass epoxy board, it sustains 200 mW continuous dissipation. Derating is required above 25°C ambient, per Figure 1 in datasheet D13910EJ2V0DS00. The NNCD6.8MG-T1-A must not exceed these limits to ensure long-term reliability.
Does the NNCD6.8MG-T1-A support IEC61000-4-2 Level 4 ESD testing?
Yes - the NNCD6.8MG-T1-A is rated for ≥30 kV contact discharge per IEC61000-4-2, exceeding Level 4 (8 kV contact / 15 kV air) requirements. This rating is verified under standardized test conditions (C = 150 pF, R = 330 Ω). The NNCD6.8MG-T1-A maintains functionality after repeated stress, making it suitable for industrial and commercial equipment subject to rigorous EMC validation.
Can the NNCD6.8MG-T1-A be used for HDMI 2.0 or USB 3.0 interfaces?
No - the NNCD6.8MG-T1-A's 20 pF capacitance is optimized for USB 2.0 (480 Mbps) and HDMI 1.4 (2.25 Gbps), but exceeds acceptable limits for USB 3.0 SuperSpeed (5 Gbps) or HDMI 2.0 (6 Gbps per lane), where <1.5 pF is typically required. For those interfaces, lower-capacitance alternatives such as TPD4E001DRYR or NUP4201MR6T1G are recommended. The NNCD6.8MG-T1-A remains ideal for legacy and mid-speed applications.
What is the pin configuration of the NNCD6.8MG-T1-A and how is it wired in circuit?
The NNCD6.8MG-T1-A uses a common-anode SC-74A pinout: Pin 1 = K1, Pin 2 = A (shared anode), Pin 3 = K2, Pin 4 = K3, Pin 5 = K4. In practice, the anode (Pin 2) connects to ground or a protected rail (e.g., VBUS), while each cathode ties to a signal line needing protection. This configuration allows bidirectional clamping - positive transients divert to ground, negative transients clamp to the rail. The NNCD6.8MG-T1-A's layout minimizes parasitic inductance for effective high-frequency ESD suppression.
Is the NNCD6.8MG-T1-A RoHS compliant and halogen-free?
Yes - the NNCD6.8MG-T1-A complies with EU RoHS Directive 2011/65/EU and is halogen-free per J-STD-709. Renesas confirms this in environmental documentation referenced under product code NNCD6.8MG-T1-A. Material declarations and test reports are available through Renesas' official portal. The NNCD6.8MG-T1-A meets global regulatory requirements for sale in EU, Japan, China, and North America.
