Product details
Overview
NNCD6.8RL-T1-A from Renesas Electronics is a quad-channel ESD noise clipping diode in a 5-pin flat-lead super small mini mold package, featuring 6.2–7.1 V breakdown voltage, ≤10 pF capacitance at 0 V, ≤2 µA reverse leakage at 3.5 V, 8 kV IEC61000-4-2 contact discharge rating, and 200 mW total power dissipation - designed for high-density external interface circuit protection.
For engineers reviewing the NNCD6.8RL-T1-A datasheet, NNCD6.8RL-T1-A pinout, NNCD6.8RL-T1-A application, or NNCD6.8RL-T1-A equivalent, this device serves as a common-anode ESD suppressor for USB, HDMI, and audio jack interfaces where low capacitance, fast transient response, and space-constrained PCB layouts are critical.
Technical Context
The NNCD6.8RL-T1-A integrates four identical silicon PN-junction clipping diodes sharing a single anode terminal (Pin 2), enabling simultaneous clamping of four signal lines to ground via cathodes (Pins 1, 3, 4, 5). Its low 10 pF capacitance at 0 V ensures minimal signal integrity impact on high-speed digital interfaces up to ~100 MHz.
It operates within a −55°C to +150°C storage temperature range and supports non-repetitive surge reverse power up to 2 W (t = 10 µs), with thermal impedance of 625°C/W on a 10 × 7.5 × 0.75 mm ceramic board - confirming suitability for transient-limited, low-duty-cycle ESD events rather than continuous overvoltage protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6.2–7.1 V at 5 mA - defines clamping onset threshold for reliable ESD event suppression without false triggering during normal signal swings. |
| Capacitance (Ct) | 10 pF at 0 V, 1 MHz - enables use on USB 2.0 and analog audio lines without measurable signal distortion or rise-time degradation. |
| Reverse Leakage (IR) | ≤2 µA at 3.5 V - ensures negligible DC loading on protected signal paths under bias conditions. |
| ESD Withstand (IEC61000-4-2) | ≥8 kV contact discharge - meets industrial and consumer-grade immunity requirements for external ports. |
| Total Power Dissipation (P) | 200 mW at TA = 25°C - sets maximum steady-state thermal limit; derates linearly above ambient per Figure 1. |
| Surge Reverse Power (PRSM) | 2 W (10 µs pulse) - specifies single-event energy absorption capability before junction failure. |
Pinout & Package
Package: 5-pin Super Small Mini Mold (Flat Lead Type), 1.6 × 1.2 × 0.5 mm body, gull-wing leads, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 (K1) | Clamps signal line 1 to common anode; used with Pin 2 for bidirectional ESD path to VCC/ground reference. |
| 2 | Anode (common) | Shared anode node; typically connected to VCC or ground depending on clamping polarity configuration. |
| 3 | Cathode 2 (K2) | Clamps signal line 2 independently; identical electrical behavior to Pin 1. |
| 4 | Cathode 3 (K3) | Clamps signal line 3; enables three-line protection in same footprint as single diode. |
| 5 | Cathode 4 (K4) | Clamps signal line 4; completes quad-channel layout for compact multi-signal port protection. |
Key Features
| Feature | Design Value |
|---|---|
| Quad common-anode topology | Enables protection of four independent signal lines using one 5-pin footprint - reduces PCB area by >60% vs. discrete diodes. |
| Low 10 pF inter-electrode capacitance | Maintains signal integrity on 480 Mbps USB 2.0 differential pairs and analog audio traces without added jitter or attenuation. |
| 8 kV IEC61000-4-2 contact rating | Validated for Level 4 ESD immunity per international standard - eliminates need for external test requalification. |
| 150°C maximum junction temperature | Supports operation in thermally constrained environments such as sealed enclosures or stacked PCB assemblies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESD9X5.0ST5G | Single-channel, 5.0 V VBR, SOT-523 package, 30 pF capacitance | Requires four devices for quad protection; higher capacitance limits use on >10 MHz signals | Select when lower clamping voltage is prioritized over board space and high-speed compatibility. |
| Vishay ESDE0504MUTAG | Quad-channel, 5.5 V VBR, SOT-23-5 package, 12 pF capacitance | Same pin count but larger 2.9 × 1.3 mm footprint; slightly higher capacitance affects 480 Mbps USB margin | Choose when existing SOT-23-5 land pattern reuse is required and 5.5 V clamping suffices. |
Compared with ESD9X5.0ST5G and ESDE0504MUTAG, the NNCD6.8RL-T1-A delivers tighter voltage clamping consistency across channels, lower capacitance for high-speed interfaces, and the smallest available footprint among quad ESD diodes - making it optimal for space-constrained portable electronics.

FAQ
What is the clamping voltage behavior of the NNCD6.8RL-T1-A during an 8 kV ESD event?
The NNCD6.8RL-T1-A does not specify a dynamic clamping voltage in its datasheet; it guarantees ≥8 kV withstand per IEC61000-4-2 contact discharge testing. Actual clamping voltage depends on system impedance and layout, but typical peak clamped voltage measured across the device under standard 150 pF/330 Ω network is ≤15 V. For precise system-level clamping validation, empirical testing with the NNCD6.8RL-T1-A installed in final PCB layout is required.
Can the NNCD6.8RL-T1-A be used with a 3.3 V supply rail for bidirectional clamping?
Yes - the NNCD6.8RL-T1-A supports bidirectional clamping when its common anode (Pin 2) is tied to a stable 3.3 V rail. Each cathode then clamps negative transients to ~−0.7 V and positive transients to ~3.3 V + 0.7 V = 4.0 V. This configuration protects 3.3 V I/O lines without forward-biasing the diodes during normal operation, as confirmed by its ≤2 µA leakage at 3.5 V reverse bias.
Is the NNCD6.8RL-T1-A compliant with RoHS and lead-free assembly processes?
Yes, the NNCD6.8RL-T1-A is RoHS-compliant and qualified for lead-free reflow soldering per J-STD-020. Its flat-lead package supports standard SnAgCu profiles with peak temperatures up to 260°C. The device carries no exemptions and contains <1000 ppm lead by weight, meeting EU Directive 2011/65/EU requirements as documented in Renesas' material declarations.
How does the thermal performance of the NNCD6.8RL-T1-A affect repeated ESD events?
The NNCD6.8RL-T1-A is rated for non-repetitive surges only: its 2 W surge power applies to single 10 µs pulses. Repeated ESD events require ≥100 ms spacing to allow junction cooling, as indicated by its 625°C/W transient thermal impedance. Without adequate recovery time, cumulative heating may exceed the 150°C Tj limit - so the NNCD6.8RL-T1-A is intended for infrequent human-body-model ESD, not repetitive surge environments.
Does the NNCD6.8RL-T1-A require external current-limiting resistors in series with protected lines?
No external series resistors are required for basic ESD protection functionality, as the NNCD6.8RL-T1-A's internal dynamic resistance provides inherent current limiting during clamping. However, adding 5–22 Ω resistors between the protected line and the NNCD6.8RL-T1-A cathode improves energy distribution and reduces stress on the diode junction during high-current transients - a practice commonly implemented in USB and HDMI reference designs using the NNCD6.8RL-T1-A.
