Product details
Overview
NUP2301MW6T1G from onsemi is a low-capacitance dual-channel ESD protection diode array in SC-88 package, rated for 70 V reverse voltage, 2.0 pF max inter-I/O capacitance, and IEC 61000-4-2 Level 4 (8 kV contact / 15 kV air) compliance-designed to safeguard high-speed data lines such as I²C buses and video interfaces against electrostatic discharge.
For engineers reviewing the NUP2301MW6T1G datasheet, pinout, applications, or equivalent options, key selection criteria include inter-pin capacitance ≤2.0 pF, bidirectional clamping capability per channel, SC-88 footprint compatibility, and AEC-Q101 qualification for automotive secondary IC protection use cases.
Technical Context
The NUP2301MW6T1G integrates two independent bidirectional ESD protection diodes in a single SC-88 package, with each channel featuring a low-leakage silicon avalanche structure optimized for fast transient response and minimal signal distortion. It operates without external bias and clamps transients between I/O pins and supply rails (VP/VN).
Its architecture supports direct connection to data lines referenced to VP (positive rail) and VN (ground), enabling transient diversion either to VP or VN via internal diode paths-verified under JEDEC JESD22-A114 (HBM Class 3B) and JESD22-A115 (MM Class C) test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 Vdc - ensures safe operation on 3.3 V, 5 V, and 12 V data line systems with margin against overvoltage events. |
| Inter-I/O Capacitance (CD) | 1.0–2.0 pF at 1 MHz - preserves signal integrity on high-speed interfaces like I²C, HDSL, and video lines up to ~100 MHz. |
| ESD Rating (IEC 61000-4-2) | 8 kV contact / 15 kV air - meets Level 4 immunity for end-equipment compliance in industrial and automotive environments. |
| Forward Voltage (VF) | 1.25 V max at 150 mA - defines clamping threshold during surge events, limiting voltage seen by protected ICs. |
| Junction Temperature Range | −55 °C to +150 °C - supports deployment in under-hood automotive, base station, and industrial control applications. |
| Package | SC-88 (Case 419B, 2.00 × 1.25 × 0.90 mm) - surface-mount footprint compatible with standard 0.65 mm pitch reflow processes. |
Pinout & Package
Package: SC-88 (Case 419B), 6-pin, Pb-free, tape-and-reel packaging (3,000 units per reel). Dimensions: 2.00 mm × 1.25 mm × 0.90 mm, 0.65 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VN) | Ground Reference Terminal | Common cathode connection point for both diode channels; must be tied to system ground plane for effective ESD shunting. |
| 2 (CH1) | Data Line 1 I/O Terminal | Bidirectional I/O pin protected by internal diode pair between CH1 and VP/VN; connects directly to first data line (e.g., SDA). |
| 3 (VP) | Positive Supply Terminal | Common anode connection point; ties to local VCC or decoupling capacitor (0.2 µF ceramic) to enable clamping to positive rail. |
| 4 (N/C) | No Connect | Internally unconnected; must remain floating-no PCB trace or solder mask opening required. |
| 5 (CH2) | Data Line 2 I/O Terminal | Bidirectional I/O pin protected by second diode pair; connects to second data line (e.g., SCL) independently of CH1. |
| 6 (N/C) | No Connect | Internally unconnected; must remain floating-no routing or termination needed. |

Applications
| I²C Bus Protection | Video Line Protection |
|---|---|
|
Use Scenario: Protecting SDA/SCL lines in microcontroller-based sensor hubs or display interface modules exposed to handling ESD. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed inline between MCU GPIO and peripheral IC, operating passively during normal signaling. Use Value: Maintains <1.5 ns response time and <2.0 pF loading to preserve I²C timing margins while surviving repeated 8 kV contact discharges. |
Use Scenario: Shielding analog RGB or LVDS video traces in automotive instrument clusters or industrial HMIs from cable-discharge events. IC Role / Device Role / Timing Role: Low-capacitance clamp on differential or single-ended video lines, referenced to local ground and supply rails. Use Value: Prevents pixel corruption or display lockup by limiting transient overshoot to <12 V without distorting 10–100 MHz video bandwidth. |
| T1/E1 Secondary IC Protection | Microcontroller Input Protection |
|
Use Scenario: Safeguarding line-interface ICs in telecom access equipment subjected to lightning-induced surges on twisted-pair copper lines. IC Role / Device Role / Timing Role: Front-end ESD guard for secondary-side transceivers, placed after isolation transformers and before receiver inputs. Use Value: Provides 70 V standoff and 15 kV air-gap ESD immunity without adding propagation delay or requiring bias circuitry. |
Use Scenario: Hardening GPIO, reset, or interrupt pins on automotive-grade MCUs used in body control modules or ADAS sensors. IC Role / Device Role / Timing Role: Standalone ESD clamp on low-speed control inputs, operating across full −55 °C to +150 °C junction range. Use Value: Eliminates need for external RC filters or TVS diodes-reduces BOM count and improves long-term reliability in vibration-prone environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Lower capacitance (0.8 pF typ), but single-channel only; requires two devices for dual-line protection. | Best suited for space-constrained designs where ultra-low capacitance dominates over channel count. | Select when protecting isolated high-frequency lines (e.g., USB D+/D−) rather than paired buses like I²C. |
| ESD5Z3.3T5G | Single-line device with 3.3 V working voltage; not rated for 70 V reverse standoff or dual-channel operation. | Applicable only for low-voltage (≤3.3 V) single-line protection; lacks VP/VN dual-rail clamping architecture. | Choose only for cost-sensitive consumer applications with strict 3.3 V rail constraints and no multi-line coordination needs. |
Compared with TPD2E001DRYR and ESD5Z3.3T5G, the NUP2301MW6T1G uniquely delivers dual-channel, 70 V-rated, bidirectional ESD protection in one SC-88 package-enabling compact, automotive-qualified designs without sacrificing voltage margin or layout efficiency.

FAQ
What is the maximum inter-I/O capacitance specified for the NUP2301MW6T1G?
The NUP2301MW6T1G has a maximum inter-I/O capacitance of 2.0 pF at 0 V reverse bias and 1.0 MHz frequency, with typical value of 1.0 pF. This low capacitance ensures minimal loading on high-speed data lines such as I²C, HDSL, and video interfaces, preserving signal edge rates and reducing jitter in real-world layouts.
Does the NUP2301MW6T1G require external bias or control signals to operate?
No, the NUP2301MW6T1G operates without external bias or control signals. Its internal bidirectional diode structure functions passively-clamping transients between CH1/CH2 and VP/VN terminals automatically upon surge event detection. This eliminates quiescent current draw and simplifies design integration.
Is the NUP2301MW6T1G qualified for automotive applications?
Yes, the NUP2301MW6T1G is AEC-Q101 qualified and PPAP capable. The SZ-prefix variant (SZNUP2301MW6T1G) is explicitly designated for automotive and other applications requiring unique site and control change requirements-validating its suitability for under-hood and infotainment subsystems.
How is the VP terminal used in the NUP2301MW6T1G circuit implementation?
The VP terminal serves as the common anode node for both ESD protection diodes. It must be connected to the local positive supply rail (e.g., 3.3 V or 5 V) through a low-ESR 0.2 µF ceramic capacitor to ground, enabling effective clamping of transients toward the positive rail during ESD events.
Can the NUP2301MW6T1G protect data lines referenced only to ground (not to VP)?
Yes-the NUP2301MW6T1G provides bidirectional clamping between each I/O pin (CH1, CH2) and both VP and VN. When VP is left unconnected or tied to a higher potential, transients are diverted to VN (ground); when VP is properly bypassed, clamping occurs to either rail depending on polarity, ensuring full protection coverage.
