Product details
Overview
NNCD5.6H-T1-AT from Renesas Electronics is a low-capacitance, quad-channel ESD protection diode in SC-88A (5-pin super small mini mold) package, featuring 5.3–6.3 V breakdown voltage, 110 pF capacitance at 0 V, 2.5 µA max reverse leakage at 2.5 V, 110 Ω dynamic impedance, and 30 kV IEC 61000-4-2 contact discharge endurance. It serves as a common-anode transient voltage suppressor for high-density USB, HDMI, and audio interface protection.
For engineers reviewing the NNCD5.6H-T1-AT datasheet, NNCD5.6H-T1-AT pinout, NNCD5.6H-T1-AT application, or NNCD5.6H-T1-AT equivalent, key selection criteria include its 5-pin common-anode quad configuration, 110 pF channel-to-ground capacitance at 0 V, 30 kV ESD robustness, 200 mW total power dissipation, and suitability for space-constrained external I/O port protection in consumer and industrial electronics.
Technical Context
This device implements four identical silicon avalanche diodes connected in a common-anode topology within a single SC-88A package, enabling simultaneous clamping of four signal lines to a shared reference rail. Its low 110 pF capacitance per channel ensures minimal signal distortion in high-speed interfaces up to 100 Mbps.
The diode operates via controlled avalanche breakdown above 5.3 V, with tight VBR tolerance (5.3–6.3 V), low dynamic impedance (110 Ω), and guaranteed 30 kV ESD immunity per IEC 61000-4-2 Contact Discharge test (C = 150 pF, R = 330 Ω). Thermal design relies on its 625 °C/W transient thermal impedance at 100 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 | Lower 15 pF capacitance but only 12 kV ESD rating; dual-rail (VCC/GND) clamping | Better for >480 Mbps interfaces; less robust for harsh industrial environments | Choose when ultra-low capacitance outweighs ESD margin requirements |
| ESD5Z5.0T1G | Single-channel, 5.0 V nominal VBR, 65 pF; requires four discrete devices | Higher board area and assembly cost; identical per-channel performance | Prefer when design flexibility or staggered replacement is needed |
Compared with TPD4E001DRYR and ESD5Z5.0T1G, the NNCD5.6H-T1-AT delivers superior ESD immunity (30 kV vs. 12 kV) in a space-saving quad configuration, though with higher capacitance-making it optimal for cost-sensitive, high-reliability consumer and industrial I/O protection where speed is secondary to ruggedness.

FAQ
What is the exact breakdown voltage range for NNCD5.6H-T1-AT?
The NNCD5.6H-T1-AT has a guaranteed breakdown voltage range of 5.3 V to 6.3 V measured at 5 mA, as specified in the Renesas D15419EJ1V0DS datasheet. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable interface protection without undershoot or premature conduction in 3.3 V or 5 V systems. The value reflects actual silicon characteristics-not typical or nominal figures-and applies to all four channels identically.
Does NNCD5.6H-T1-AT support bidirectional ESD protection?
Yes, the NNCD5.6H-T1-AT provides bidirectional ESD protection through its common-anode quad configuration: each cathode pin (1, 3, 4, 5) clamps positive transients to the anode (pin 2), and negative transients are shunted via forward conduction from cathode to anode. This architecture enables full ±30 kV IEC 61000-4-2 compliance without external biasing. The NNCD5.6H-T1-AT achieves symmetrical clamping thresholds in both directions due to matched diode characteristics across all four elements.
What is the maximum operating temperature for NNCD5.6H-T1-AT?
The NNCD5.6H-T1-AT has a maximum junction temperature of 150 °C and a storage temperature range of −55 °C to +150 °C, per its Renesas datasheet. Its thermal performance is characterized by a transient thermal impedance of 625 °C/W at 100 µs, allowing safe operation under repetitive ESD pulses in ambient temperatures up to 85 °C. Derating begins above 25 °C ambient, with power dissipation reduced linearly to zero at 150 °C case temperature-ensuring robustness in sealed consumer enclosures where the NNCD5.6H-T1-AT is commonly deployed.
Can NNCD5.6H-T1-AT be used in automotive applications?
The NNCD5.6H-T1-AT is rated as a "Standard" quality grade device per Renesas documentation and is intended for applications including computers, communications equipment, and home electronics-not automotive or safety-critical systems. While it meets basic ESD requirements, it lacks AEC-Q200 qualification, extended temperature validation, or PPAP documentation required for automotive use. For vehicle infotainment or body control modules, Renesas recommends qualified alternatives like the RCLAMP0524P.TCT. The NNCD5.6H-T1-AT remains appropriate for non-automotive industrial and consumer designs.
Is NNCD5.6H-T1-AT RoHS compliant?
Yes, the NNCD5.6H-T1-AT complies with the EU RoHS Directive (2011/65/EU) as confirmed by Renesas Electronics' environmental compliance statements and material declarations. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE) above threshold limits. The device uses matte tin lead finish and halogen-free molding compound, supporting lead-free reflow profiles up to 260 °C peak. Full RoHS documentation for the NNCD5.6H-T1-AT is available through Renesas' official compliance portal.
