Product details
Overview
NNCD5.6DA-T1-AT from Renesas Electronics is an ESD noise clipping diode designed for transient voltage suppression in external interface circuits. It features a breakdown voltage of 5.29–5.94 V, dynamic impedance of 80 Ω at 5 mA, reverse leakage ≤5 μA at 2.5 V, capacitance of 140 pF at 1 MHz, and IEC61000-4-2-rated ESD protection up to ±30 kV. It is used in USB, audio jack, and parallel interface protection.
For engineers reviewing the NNCD5.6DA-T1-AT datasheet, NNCD5.6DA-T1-AT pinout, NNCD5.6DA-T1-AT application, or NNCD5.6DA-T1-AT equivalent, key selection criteria include clamping voltage accuracy, low dynamic impedance for fast response, low capacitance to preserve signal integrity, and SC-76 package compatibility with high-density PCB layouts.
Technical Context
This device operates as a unidirectional silicon avalanche diode optimized for electrostatic discharge immunity per IEC61000-4-2. Its clamping action begins near 5.6 V nominal breakdown, with low dynamic impedance (80 Ω) ensuring rapid voltage limiting during sub-microsecond transients.
It is rated for 85 W surge reverse power (tT = 10 μs), 200 mW steady-state power dissipation on standard FR-4 PCB, and junction temperature up to 150°C - enabling reliable operation in consumer and industrial interface environments without active thermal management.

|---|---|
Use Scenario: Protecting USB D+ and D− lines against user-handling ESD during cable insertion/removal in printers, peripherals, and embedded hosts. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between signal line and ground, activated only above 5.6 V to shunt transient energy. Use Value: Prevents latch-up or damage to USB transceivers (e.g., TUSB2036, CH340) while maintaining <140 pF loading for full-speed signaling compliance. | Use Scenario: Shielding 3.5 mm stereo headphone/mic jacks from ESD during plug insertion in laptops, portable media players, and smart speakers. IC Role / Device Role / Timing Role: Ground-referenced clipping diode on tip/ring/sleeve paths, clamping positive transients before they reach codec inputs. Use Value: Eliminates audible pop/crackle and prevents input-stage saturation in audio codecs (e.g., WM8731, TLV320AIC3104) without degrading frequency response. |
| Parallel Interface Protection | Industrial Sensor I/O Guarding |
Use Scenario: Safeguarding legacy parallel port pins (STROBE, ACK, BUSY) in industrial controllers and test equipment exposed to operator touch. IC Role / Device Role / Timing Role: Discrete clamping element on each signal line, operating independently to limit voltage excursions to ≤6 V. Use Value: Maintains logic-level compatibility with 5 V TTL/CMOS receivers while surviving >10,000 ESD events per pin per IEC61000-4-2. | Use Scenario: Protecting analog/digital sensor inputs (e.g., thermocouple, RTD, digital switch) on PLC I/O modules mounted in open cabinets. IC Role / Device Role / Timing Role: First-line transient suppressor on field-side signal traces, diverting ESD before reaching isolation barriers or ADC front-ends. Use Value: Enables robust operation in factory-floor environments where operators frequently handle connectors, reducing field returns due to interface failures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z5.0T1G (ON Semiconductor) | 5.0 V nominal VBR, 100 pF capacitance, 100 W PRSM | Slightly lower clamping voltage; better suited for 3.3 V logic rails | Select when protecting 3.3 V interfaces where tighter VBR margin is required |
| TPD2E001DRYR (Texas Instruments) | Dual-channel, 15 pF per line, 12 kV IEC61000-4-2 rating | Lower capacitance but lower ESD rating; requires two lines per signal | Prefer for high-speed data lines (e.g., HDMI, SDIO) where <20 pF loading is mandatory |
Compared with ESD5Z5.0T1G and TPD2E001DRYR, the NNCD5.6DA-T1-AT offers higher ESD immunity (±30 kV vs. ±12–±15 kV), higher surge power tolerance (85 W vs. 60–75 W), and optimal VBR alignment for 5 V interface protection - making it ideal for legacy parallel, USB 2.0, and industrial I/O where robustness outweighs ultra-low capacitance needs.

FAQ
What is the breakdown voltage range of the NNCD5.6DA-T1-AT?
The NNCD5.6DA-T1-AT has a guaranteed breakdown voltage range of 5.29 V to 5.94 V at 5 mA test current, measured using a 40 ms pulse per the official datasheet. This tight VBR window ensures consistent clamping behavior across production lots and enables reliable overvoltage protection for 5 V systems without premature conduction during normal operation.
Is the NNCD5.6DA-T1-AT RoHS compliant?
Yes, the NNCD5.6DA-T1-AT is RoHS compliant, featuring pure tin (Sn) lead plating on its external electrodes and no lead content in any part of the device. This complies with EU Directive 2011/65/EU and meets JEDEC J-STD-609 Class 1 moisture sensitivity level (MSL-1) for unlimited floor life at ambient conditions.
What is the maximum surge power rating for the NNCD5.6DA-T1-AT?
The NNCD5.6DA-T1-AT is rated for 85 W of non-repetitive surge reverse power (PRSM) with a 10 μs pulse width, as defined in Figure 5 of the datasheet. This rating reflects its ability to absorb high-energy ESD transients without degradation, supporting long-term reliability in environments with frequent human-handling events.
Can the NNCD5.6DA-T1-AT be used for bidirectional ESD protection?
No, the NNCD5.6DA-T1-AT is a unidirectional diode intended for ground-referenced clamping only. It protects against positive transients on the anode relative to cathode (ground). For bidirectional protection, two devices must be used in series opposition or a dedicated bidirectional TVS like P6SMB5.0A should be selected instead.
What is the typical capacitance of the NNCD5.6DA-T1-AT at 1 MHz?
The NNCD5.6DA-T1-AT exhibits a typical capacitance of 140 pF at 1 MHz and 0 V bias, as specified in the Electrical Characteristics table. This value is measured under standardized conditions and remains stable across temperature, making it suitable for low-to-medium speed digital and analog signal lines where minimal capacitive loading is acceptable.
