Product details
Overview
NNCD5.6MG-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, 5.3–6.3 V breakdown voltage, 20 pF typical capacitance at 1 MHz, and 30 kV IEC61000-4-2 ESD immunity-designed for USB and high-speed data line protection.
For engineers reviewing the NNCD5.6MG-T1-A datasheet, NNCD5.6MG-T1-A pinout, NNCD5.6MG-T1-A application, or NNCD5.6MG-T1-A equivalent, key selection criteria include clamping performance under 10 µs surge, channel-to-channel isolation in common-anode topology, reverse leakage ≤5 µA at 2.5 V, and compatibility with 0.65 mm pitch PCB layouts.
Technical Context
This device implements four independent Zener-clamp diodes sharing a single anode terminal, enabling bidirectional transient suppression across four signal lines relative to a common reference. Each cathode-anode path exhibits tightly controlled 5.3–6.3 V breakdown with dynamic impedance ≤80 Ω at 5 mA.
Its 20 pF typical junction capacitance (measured at VR = 0 V, f = 1 MHz) and low leakage support signal integrity on USB 1.1/2.0 full-speed interfaces. The SC-74A package supports high-density mounting with 0.65 mm lead pitch and thermal resistance optimized for 30 mm × 30 mm × 1.6 mm FR-4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 5.3–6.3 V (min/max at IT = 5 mA); ensures reliable clamping before damage to downstream 3.3 V or 5 V transceivers |
| Capacitance | 20 pF typ. at VR = 0 V, 1 MHz; preserves signal rise/fall times on USB D+/D− lines |
| ESD Withstand | ≥30 kV per IEC61000-4-2 contact discharge; meets industrial and consumer system-level ESD requirements |
| Dynamic Impedance | ≤80 Ω at IT = 5 mA; limits clamping voltage overshoot during fast transients |
| Reverse Leakage | ≤5 µA at VR = 2.5 V; avoids DC loading on bias-sensitive data lines |
| Surge Power | 2 W peak (t = 10 µs, non-repetitive); handles single-event electrostatic events without degradation |
Pinout & Package
SC-74A (5-pin Mini Mold), 2.9 mm × 1.5 mm footprint, 0.65 mm lead pitch, gull-wing leads. RoHS-compliant, lead-free finish.

| 2 (A) | Common Anode | Reference node tied to GND or VCC via low-inductance path |
| 3 (K2) | Cathode of Channel 2 | Connects to protected signal line 2 (e.g., USB D−) |
| 4 (K3) | Cathode of Channel 3 | Supports third I/O line (e.g., ID or VBUS sense) |
| 5 (K4) | Cathode of Channel 4 | Enables fourth protected line without adding discrete devices |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DRYR | Lower 0.75 pF capacitance but rated only to 12 kV IEC61000-4-2; uses different SC-70-6 package | Better for >1 Gbps interfaces (e.g., PCIe Gen1), unsuitable for system-level 30 kV compliance testing | Select when ultra-low capacitance outweighs ESD rating requirement |
| ESD5Z5.0T1G | Single-channel, 5.0 V nominal breakdown, 25 pF capacitance, SOD-523 package | Requires four separate placements; higher total board area and inductance vs. integrated quad solution | Choose only if legacy layout lacks space for SC-74A or requires asymmetric channel count |
Compared with TPD4E001DRYR and ESD5Z5.0T1G, the NNCD5.6MG-T1-A uniquely delivers certified 30 kV system-level ESD robustness in a space-saving quad common-anode configuration-making it optimal for USB, HDMI, and industrial serial interfaces where both density and compliance are mandatory.

FAQ
What is the maximum operating temperature for NNCD5.6MG-T1-A?
The NNCD5.6MG-T1-A has a maximum junction temperature of 150°C and a storage temperature range of −55°C to +150°C. Its thermal performance is characterized for use on standard 30 mm × 30 mm × 1.6 mm FR-4 PCBs, with transient thermal impedance dropping to ~625°C/W at t = 1 ms. Derating is required above 25°C ambient per the power dissipation vs. temperature curve in the datasheet.
Does NNCD5.6MG-T1-A support bidirectional ESD protection?
Yes, the NNCD5.6MG-T1-A provides bidirectional protection per channel due to its Zener-based structure-each cathode-anode path conducts in reverse breakdown during positive transients and forward-biases during negative transients relative to the common anode. This enables full protection of AC-coupled or differential signals like USB D+/D− without polarity constraints.
Is NNCD5.6MG-T1-A RoHS compliant and lead-free?
Yes, NNCD5.6MG-T1-A is RoHS compliant and features a lead-free finish per Renesas' environmental specifications. It meets EU RoHS Directive requirements for restricted substances and is manufactured using Pb-free solder reflow profiles compatible with standard surface-mount assembly processes.
Can NNCD5.6MG-T1-A be used for 5 V logic rail protection?
No-NNCD5.6MG-T1-A is not intended for power-rail clamping. Its 5.3–6.3 V breakdown is designed for signal-line ESD suppression, not sustained overvoltage on supply rails. For 5 V rail protection, Renesas recommends dedicated TVS arrays such as the RCLAMP series with higher surge ratings and lower clamping voltages at high current.
What is the typical clamping voltage of NNCD5.6MG-T1-A during a 30 kV ESD event?
The NNCD5.6MG-T1-A does not specify a single clamping voltage value at 30 kV, as clamping depends on test waveform and circuit layout. However, based on its 80 Ω dynamic impedance and 5 mA breakdown test condition, the device clamps to approximately 10–12 V peak during IEC61000-4-2 contact discharge when mounted with minimal trace inductance-verified in Renesas' application layout examples.
