Product details
Overview
NNCD6.8LH-T1-A from Renesas Electronics is a low-capacitance, quad-channel ESD protection diode in a 5-pin super mini mold package with common-anode configuration. It delivers 6.2–7.1 V breakdown voltage, ≤7 pF capacitance at 0 V, ≤30 Ω dynamic impedance, ≤2 µA reverse leakage, and 8 kV IEC 1000-4-2 contact discharge ESD immunity - optimized for USB 2.0 and high-speed data line protection.
For engineers reviewing the NNCD6.8LH-T1-A datasheet, NNCD6.8LH-T1-A pinout, NNCD6.8LH-T1-A application, or NNCD6.8LH-T1-A equivalent, this device offers verified ESD clamping performance, precise low-capacitance matching for signal integrity, and validated quad-diode integration in a space-constrained 2.1 × 2.0 mm footprint.
Technical Context
This ESD protection array uses four identical silicon PN-junction diodes connected in common-anode topology, enabling simultaneous clamping of four independent signal lines to ground via shared anode connection. Each cathode-anode path supports bidirectional transient suppression with fast response (<1 ns) and low clamping voltage under 8 kV ESD stress.
The device operates within –55°C to +150°C storage range and 150°C maximum junction temperature, rated for 200 mW total power dissipation and 2 W surge reverse power (10 µs pulse). Its 7 pF typical capacitance at 0 V and 1 MHz ensures minimal signal distortion on USB full-speed (12 Mbps) and high-speed (480 Mbps) differential pairs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DRYR | 4-channel, 0.5-pF typical capacitance; lower clamping voltage but 6 kV IEC 1000-4-2 rating | Better suited for USB 3.0/PCIe where ultra-low capacitance is critical; less margin for high-energy ESD events | Select when signal bandwidth exceeds 5 GHz and ESD threat level is ≤6 kV contact |
| ESD5Z7.0T1G | Single-channel, 7.0 V breakdown, 12 pF capacitance, SOD-523 package | Requires four separate placements; higher board area and assembly cost than quad NNCD6.8LH-T1-A | Choose only if existing layout lacks space for 5-pin QFN-style footprint or requires discrete replacement |
Compared with TPD4E001DRYR and ESD5Z7.0T1G, NNCD6.8LH-T1-A provides balanced ESD immunity (8 kV), moderate capacitance (7 pF), and integrated quad-channel packaging - making it optimal for cost-sensitive, space-constrained USB 2.0 designs requiring proven field reliability.

FAQ
What is the maximum operating temperature for NNCD6.8LH-T1-A?
NNCD6.8LH-T1-A has a maximum junction temperature of 150°C and a storage temperature range of –55°C to +150°C. It is rated for continuous operation up to this junction limit when power dissipation remains within the 200 mW total rating and thermal design accounts for PCB copper area and ambient conditions. Derating is required above 25°C ambient per the P–TA curve in the datasheet.
Does NNCD6.8LH-T1-A support both contact and air-gap ESD testing per IEC 61000-4-2?
NNCD6.8LH-T1-A is specified for ≥8 kV contact discharge per IEC 1000-4-2 (now IEC 61000-4-2). The datasheet does not list air-gap discharge rating; however, its clamping performance and structure imply functional air-gap capability up to 15 kV - though formal validation requires system-level testing. Always verify final design compliance with full-system ESD testing.
Can NNCD6.8LH-T1-A be used for HDMI or DisplayPort ESD protection?
NNCD6.8LH-T1-A is not recommended for HDMI or DisplayPort due to its 7 pF capacitance - exceeding the <0.5 pF typical requirement for 2.25+ Gbps serial links. While it may function at lower data rates, signal integrity degradation and eye diagram closure would occur. For those interfaces, Renesas' newer ultra-low-capacitance arrays like the RCLAMP series are preferred.
What is the anode connection configuration in NNCD6.8LH-T1-A?
NNCD6.8LH-T1-A uses a common-anode configuration: Pin 2 is the shared anode terminal connected to system ground or reference plane, while Pins 1, 3, 4, and 5 are individual cathodes (K1–K4) for each protected signal line. This allows bidirectional clamping from signal to ground and simplifies PCB routing with one ground tie point.
Is NNCD6.8LH-T1-A RoHS compliant and lead-free?
Yes, NNCD6.8LH-T1-A is RoHS compliant and lead-free. Per Renesas' environmental documentation and product marking, it conforms to EU RoHS Directive 2011/65/EU and subsequent amendments. The "-T1-A" suffix denotes tape-and-reel packaging with lead-free termination finish meeting J-STD-020 moisture sensitivity level 1.
