Product details
Overview
NNCD5.6LH-T1-A from Renesas Electronics is a low-capacitance quad ESD protection diode in a 5-pin super mini mold package with common anode configuration. It delivers 5.3–6.3 V breakdown voltage, ≤10 pF capacitance at 0 V/1 MHz, 8 kV IEC 61000-4-2 contact discharge ESD immunity, and 2 W surge power handling for high-speed USB interface protection.
For engineers reviewing the NNCD5.6LH-T1-A datasheet, NNCD5.6LH-T1-A pinout, NNCD5.6LH-T1-A application, or NNCD5.6LH-T1-A equivalent, this device is selected specifically for compact, multi-line ESD clamping in space-constrained USB 2.0, HDMI, and serial data paths where signal integrity and board density are critical.
Technical Context
The NNCD5.6LH-T1-A integrates four identical Zener-based ESD clamping diodes sharing a single anode terminal, forming a quartet structure optimized for bidirectional transient suppression on four independent signal lines. Each cathode-anode path exhibits dynamic impedance ≤80 Ω at 5 mA and leakage current ≤5 µA at 2.5 V reverse bias.
Its 10 pF inter-terminal capacitance (measured at VR = 0 V, f = 1 MHz) and fast response enable minimal signal distortion on high-speed differential or single-ended buses up to 480 Mbps. Thermal performance supports 200 mW continuous dissipation with junction temperature limited to 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 5.3–6.3 V min/max - defines clamping onset threshold for reliable ESD voltage limiting on protected lines |
| Reverse Capacitance (Ct) | 10 pF typ @ 0 V, 1 MHz - ensures <1% signal attenuation on USB 2.0 full-speed (12 Mbps) and high-speed (480 Mbps) links |
| ESD Withstand (IEC 61000-4-2) | ≥8 kV contact discharge - meets industrial and consumer-grade system-level ESD immunity requirements |
| Surge Power Rating (PRSM) | 2 W @ 10 µs pulse - handles single-event ESD transients without degradation or latch-up |
| Dynamic Impedance (Zz) | ≤80 Ω @ 5 mA - enables rapid voltage clamping to limit peak transient overshoot below IC damage thresholds |
| Leakage Current (IR) | ≤5 µA @ 2.5 V - prevents measurable DC loading on high-impedance data lines such as USB D+/D− |
Pinout & Package
Package: 5-pin super mini mold (SOT-353-compatible footprint), dimensions 2.1 × 2.0 × 0.9 mm, surface-mount, RoHS-compliant.

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 0.5 pF capacitance but rated only to 12 kV air/8 kV contact; uses different 5-pin SON package (1.45 × 1.0 mm) | Preferred for ultra-high-speed interfaces (>5 Gbps) where sub-1 pF is mandatory; less suitable for cost-sensitive USB 2.0 designs | Select when minimizing capacitive loading outweighs package compatibility and cost constraints |
| ESD5Z5.0T1G | Single-channel, SOD-523 package; 5.0 V nominal breakdown; 65 pF capacitance - significantly higher than NNCD5.6LH-T1-A's 10 pF | Only appropriate for low-speed digital lines (<1 Mbps); unsuitable for USB 2.0 or HDMI DDC due to bandwidth limitation | Choose only for non-high-speed GPIO or power rail clamping where board space allows discrete placement |
Compared with TPD4E05U06DQAR and ESD5Z5.0T1G, the NNCD5.6LH-T1-A uniquely balances quad-channel integration, 10 pF capacitance, and proven USB 2.0 compatibility in a widely adopted 5-pin super mini mold footprint-making it optimal for cost-sensitive, density-constrained consumer and industrial interfaces.

FAQ
What is the maximum operating temperature for the NNCD5.6LH-T1-A?
The NNCD5.6LH-T1-A has a maximum junction temperature (Tj) rating of 150°C and a storage temperature range of –55°C to +150°C. Its thermal design supports continuous operation at ambient temperatures up to 125°C when mounted on standard FR-4 PCBs with typical copper pour, based on its 625°C/W transient thermal impedance and 200 mW total power dissipation limit. Derating is required above 25°C ambient per the P–TA curve in the datasheet.
Does the NNCD5.6LH-T1-A meet IEC 61000-4-2 Level 4 ESD requirements?
Yes, the NNCD5.6LH-T1-A is tested and specified to withstand ≥8 kV contact discharge per IEC 61000-4-2, satisfying Level 4-the highest severity level defined in the standard. This performance is validated across all four channels (K1–K4 to common anode) and applies to both single-pulse and repetitive ESD events under standard test conditions (C = 150 pF, R = 330 Ω).
Can the NNCD5.6LH-T1-A be used for HDMI TMDS line protection?
No, the NNCD5.6LH-T1-A is not recommended for HDMI TMDS (Transition-Minimized Differential Signaling) line protection. Its 10 pF capacitance exceeds the strict <1.5 pF requirement for 1080p/4K TMDS channels operating at 2.25+ Gbps. It is qualified for HDMI DDC (I²C) and CEC lines only, where bandwidth demands are lower and 10 pF poses no signal integrity risk.
What is the reverse leakage current specification for the NNCD5.6LH-T1-A at 2.5 V?
The NNCD5.6LH-T1-A specifies a maximum reverse leakage current (IR) of 5 µA at VR = 2.5 V and TA = 25°C, measured across each cathode-to-anode junction (K1–A, K2–A, etc.). This low leakage ensures negligible DC loading on high-impedance signal lines such as USB D+/D− or HDMI DDC SDA/SCL, preserving logic thresholds and pull-up functionality.
Is the NNCD5.6LH-T1-A RoHS compliant and lead-free?
Yes, the NNCD5.6LH-T1-A is RoHS compliant and lead-free. The "-T1-A" suffix denotes tape-and-reel packaging with lead-free termination finish, consistent with Renesas' environmental compliance program and EU Directive 2011/65/EU. Full material declarations and substance compliance reports are available through Renesas' official product portal.
