Product details
Overview
NUP2301MW6T1 from onsemi is a low-capacitance dual-channel ESD protection diode array in SC-88 (SOT-363) package, rated for 70 V reverse voltage, 2.0 pF max inter-I/O capacitance, and IEC 61000-4-2 Level 4 compliance (8 kV contact / 15 kV air). It protects two high-speed data lines-such as I²C bus or video interfaces-against electrostatic discharge without signal integrity degradation.
For engineers reviewing the NUP2301MW6T1 datasheet, pinout, applications, or equivalent options, key selection criteria include its 2.0 pF inter-pin capacitance, dual-channel unidirectional clamping architecture, SC-88 footprint compatibility, and AEC-Q101 qualification for automotive secondary IC protection.
Technical Context
The NUP2301MW6T1 integrates two independent unidirectional ESD protection diodes in a single SC-88 package, each with 70 V reverse breakdown voltage and clamping action to VP (positive rail) or VN (ground). Its design routes transients away from protected I/O pins using internal diode-to-rail paths, requiring external 0.2 µF low-ESR ceramic bypass between VP and VN.
It operates across −55 °C to +150 °C junction temperature, supports 200 mA continuous forward current per diode, and delivers <2.0 pF inter-I/O capacitance at 1 MHz-enabling use in >100 Mbps digital interfaces without measurable signal distortion.
Key Specifications

Pinout & Package
SC-88 (Case 419B, Style 23) surface-mount package with 6-pin configuration. Pin 1 = VN (ground reference), Pin 2 = CH1 (I/O 1), Pin 3 = VP (positive rail), Pin 4 = NC, Pin 5 = CH2 (I/O 2), Pin 6 = NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VN | Ground reference node for ESD current return path; must be connected to low-impedance system ground |
| 2 | CH1 | Protected data line 1 input/output; clamped to VP or VN during ESD event |
| 3 | VP | Positive supply rail connection; requires 0.2 µF low-ESR ceramic capacitor to VN for effective clamping |
| 4 | N/C | No internal connection - left floating or grounded per layout best practice |
| 5 | CH2 | Protected data line 2 input/output; functionally identical to CH1 with independent diode path |
| 6 | N/C | No internal connection - left floating or grounded per layout best practice |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G | Single-channel, 3.3 V working voltage, 0.5 pF capacitance - lower clamping voltage but no dual-line integration | Requires two devices for dual-line protection; better suited for ultra-low-voltage 1.8 V I/O | Select when lower clamping voltage (<10 V) is prioritized over board space savings |
| TPD2E001DRYR | Two-channel, 5.5 V working voltage, 3.5 pF inter-pin capacitance - higher capacitance limits use to ≤10 Mbps interfaces | Designed for USB 2.0 and general-purpose I/O; lacks AEC-Q101 qualification | Select for cost-sensitive consumer electronics where automotive qualification is unnecessary |
Compared with ESD5Z3.3T5G and TPD2E001DRYR, the NUP2301MW6T1 uniquely balances dual-channel integration, 2.0 pF capacitance, 70 V standoff, and AEC-Q101 compliance-making it optimal for space-constrained automotive and telecom secondary protection where signal speed and reliability are co-prioritized.

FAQ
What is the maximum inter-I/O capacitance of the NUP2301MW6T1?
The NUP2301MW6T1 has a maximum inter-I/O capacitance of 2.0 pF at 0 V bias and 1.0 MHz, with typical value of 1.0 pF. This low capacitance ensures minimal signal distortion on high-speed interfaces such as I²C and video lines. The specification is measured between pins 2 (CH1) and 5 (CH2), and is critical for maintaining rise/fall time integrity in digital communication links. NUP2301MW6T1 maintains this performance across its full operating temperature range.
Does the NUP2301MW6T1 require an external capacitor, and if so, what type?
Yes, the NUP2301MW6T1 requires a 0.2 µF low-ESR ceramic capacitor connected between VP (pin 3) and VN (pin 1) to provide an effective low-impedance path for ESD current. This capacitor must be placed within 5 mm of the device to minimize inductance and ensure proper clamping behavior during IEC 61000-4-2 discharge events. NUP2301MW6T1's internal architecture relies on this external component to route transients safely to ground or VCC.
Is the NUP2301MW6T1 qualified for automotive applications?
Yes, the NUP2301MW6T1 is AEC-Q101 qualified and PPAP capable, with the SZ-prefix variant (SZNUP2301MW6T1G) explicitly designated for automotive use. It meets stringent reliability requirements including temperature cycling, mechanical shock, and ESD robustness testing per automotive standards. NUP2301MW6T1 is deployed in T1/E1 secondary IC protection and infotainment system interfaces where qualification is mandatory.
What is the reverse breakdown voltage rating of the NUP2301MW6T1?
The NUP2301MW6T1 has a minimum reverse breakdown voltage (V(BR)) of 70 V at 100 µA test current, verified per JEDEC JESD22-A114. This rating applies to each individual diode channel (CH1 and CH2), ensuring robust protection for 5 V and 3.3 V logic systems with sufficient margin against sustained overvoltage. NUP2301MW6T1 maintains this breakdown threshold across its full −55 °C to +150 °C junction temperature range.
How does the NUP2301MW6T1 differ from bidirectional ESD arrays?
The NUP2301MW6T1 uses a unidirectional clamping architecture-each channel clamps only toward VP or VN-not bidirectionally across the rail. This avoids leakage and false triggering on DC-biased lines like I²C, where bidirectional devices may conduct during normal operation. NUP2301MW6T1's pinout (CH1/CH2 referenced to VP/VN) enforces this behavior, distinguishing it from generic bidirectional arrays such as PUSB3FR.
