Product details
Overview
NNCD6.2G-T1-AT from Renesas Electronics is a quad-channel ESD protection diode in a 5-pin Mini Mold (SC-74A) package with common anode configuration, featuring a breakdown voltage of 5.86–6.53 V, dynamic impedance ≤50 Ω at 5 mA, reverse leakage ≤2 µA at 3.0 V, capacitance of 120 pF at 1 MHz, and IEC 1000-4-2 ESD endurance ≥30 kV. It protects parallel interface lines in PC peripherals such as CD-ROM drives and printers.
For engineers reviewing the NNCD6.2G-T1-AT datasheet, NNCD6.2G-T1-AT pinout, NNCD6.2G-T1-AT application, or NNCD6.2G-T1-AT equivalent, key selection criteria include common-anode quad topology, 30 kV IEC 1000-4-2 rating, 120 pF signal-line capacitance, 50 Ω dynamic impedance, and SC-74A surface-mount compatibility for high-density PCB layouts.
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 transients. Its low dynamic impedance (≤50 Ω) ensures rapid clamping response during 8/20 µs surge events, while the 120 pF junction capacitance maintains signal integrity for DC–low-MHz interfaces like parallel printer ports.
The NNCD6.2G-T1-AT operates within a –55 °C to +150 °C storage temperature range and supports 200 mW total power dissipation at 25 °C ambient. Its surge reverse power rating is 85 W for a 10 µs single pulse, validated per IEC 1000-4-2 Level 4 testing conditions (150 pF/330 Ω network).

IC Role / Device Role / Timing Role: Front-end ESD guard for microcontroller I/O pins driving Centronics-compatible signals. Use Value: Achieves full IEC 61000-4-2 Level 4 compliance without compromising signal edge rates on 1–5 MHz control waveforms. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | Lower capacitance (0.5 pF), higher ESD rating (±12 kV contact), but dual-channel only; requires two devices for quad coverage | Better suited for high-speed USB or HDMI lines; not optimized for parallel bus capacitance tolerance | Select when protecting >100 MHz signals where <1 pF loading is mandatory |
| ESD5Z6.0T1G | Single-channel SOD-523 device with same 6.0 V nominal breakdown; no integrated quad topology or common anode | Requires four discrete placements and routing; increases PCB area and assembly cost | Choose only if legacy design uses SOD-523 footprints and cannot accommodate SC-74A |
Compared with TPD4E05U06DQAR and ESD5Z6.0T1G, the NNCD6.2G-T1-AT delivers optimal balance of quad integration, 120 pF signal-line loading, and 30 kV IEC 1000-4-2 compliance-making it uniquely suited for cost-sensitive, space-constrained parallel interface protection where moderate bandwidth suffices.

FAQ
What is the maximum operating temperature for the NNCD6.2G-T1-AT?
The NNCD6.2G-T1-AT has a maximum junction temperature of 150 °C and a storage temperature range of –55 °C to +150 °C. Its thermal performance is characterized by a transient thermal impedance of 625 °C/W at t = 1 ms, supporting reliable operation in industrial ambient environments up to 85 °C with appropriate PCB copper pour.
Does the NNCD6.2G-T1-AT meet IEC 61000-4-2 Level 4 requirements?
Yes, the NNCD6.2G-T1-AT is rated for ≥30 kV contact discharge per IEC 1000-4-2 (now superseded by IEC 61000-4-2), satisfying Level 4 immunity requirements. This rating is verified under standardized test conditions using a 150 pF capacitor and 330 Ω series resistor network, as documented in the original Renesas datasheet D11645EJ1V1DS00.
Can the NNCD6.2G-T1-AT be used for bidirectional signal protection?
No-the NNCD6.2G-T1-AT is a unidirectional common-anode device intended for clamping signals referenced to ground or VCC. For true bidirectional protection (e.g., data lines swinging above and below reference), a dual-rail or TVS array with symmetrical breakdown is required; the NNCD6.2G-T1-AT functions only as a ground-referenced shunt clamp.
What is the typical junction capacitance of the NNCD6.2G-T1-AT at 1 MHz?
The typical junction capacitance of the NNCD6.2G-T1-AT is 120 pF measured at 1 MHz and 0 V reverse bias. This value is specified in the "Electrical Characteristics" table of the Renesas datasheet and remains stable across process and temperature variations within the device's operating range.
Is the NNCD6.2G-T1-AT RoHS compliant?
Yes, the NNCD6.2G-T1-AT complies with the EU RoHS Directive. Renesas confirms RoHS compliance for this product family in its environmental documentation, and the device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits. Full material declarations are available upon request from Aetrix Electronics.
