Product details
Overview
NUP4301MR6T1 from onsemi is a low-capacitance quad ESD protection diode array in TSOP-6 package, rated for 70 V reverse voltage, 1.5 pF max inter-I/O capacitance, and IEC 61000-4-2 Level 4 (8 kV contact / 15 kV air) compliance-designed for high-speed data line protection in USB 2.0 and I²C interfaces.
For engineers reviewing the NUP4301MR6T1 datasheet, pinout, applications, or equivalent options, this device delivers verified ESD robustness with minimal signal distortion, making it critical for compact, high-reliability interface protection where board space and signal integrity are constrained.
Technical Context
The NUP4301MR6T1 integrates four independent bidirectional ESD protection diodes in a single TSOP-6 package, each configured as a low-leakage, low-capacitance clamp between I/O lines and ground or VP rail. It operates within −40°C to +85°C junction temperature range and supports transient clamping without forward-biasing under normal signal swing.
Its design implements MicroIntegration™ architecture to replace discrete TVS diodes, reducing parasitic inductance and enabling sub-nanosecond response to ESD events while maintaining <1.5 pF inter-pin capacitance-essential for preserving signal rise/fall times in 480 Mbps USB 2.0 channels.
Key Specifications

| Inter-I/O Capacitance | Max 1.5 pF at 1 MHz - preserves signal integrity up to USB 2.0 speeds |
| Reverse Standoff Voltage | 70 V - protects 3.3 V/5 V data lines with sufficient margin |
| Clamping Voltage (IPP = 1 A) | Typ. 12.5 V - limits transient overvoltage to safe levels for downstream ICs |
| Leakage Current (VR = 70 V) | Max 2.5 µA at 25°C - avoids DC loading of sensitive I/O pins |
| Junction Temperature Range | −40°C to +85°C - suitable for commercial and extended-temperature embedded applications |
Pinout & Package
Package: TSOP-6 (Case 318F), surface-mount, 1.65 mm × 2.50 mm footprint, 0.65 mm pitch, JEDEC-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| USB 2.0 Data Line Protection | I²C Bus Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of a USB 2.0 transceiver against ESD during hot-plug events in portable docking stations. IC Role / Device Role / Timing Role: ESD transient suppressor placed directly at connector, clamping fast-rising discharges before they reach PHY IC.

IC Role / Device Role / Timing Role: Low-leakage (≤2.5 µA) bidirectional clamp that avoids DC bias shift on open-drain bus lines. Use Value: Prevents latch-up or damage from 15 kV air-gap ESD while adding negligible capacitive load to 400 kHz bus timing. |
| T1/E1 Secondary IC Protection | Video Line Protection |
Use Scenario: Shielding transformer-coupled T1/E1 line-interface ICs from induced surges in telecom central office equipment. IC Role / Device Role / Timing Role: Secondary-side transient protector located after isolation transformer, referenced to local ground. Use Value: Withstands repetitive 70 V reverse standoff and clamps transients below 15 V, protecting sensitive line-driver inputs. | Use Scenario: Guarding analog video outputs (e.g., CVBS, Y/C) in set-top boxes against user-handling ESD during cable insertion. IC Role / Device Role / Timing Role: Low-distortion shunt protector with <3 pF I/O-to-ground capacitance, minimizing video signal degradation. Use Value: Ensures no visible ghosting or brightness shift in composite video due to ultra-low parasitic capacitance. |
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, 0.9 pF typical capacitance - lower clamping but no multi-line integration | Requires four devices + layout duplication; better for ultra-low-capacitance single-line needs | Choose when optimizing for <1 pF per line and board space is not constrained |
| TPD2E001DRYR | Quad-channel, 5.5 V working voltage, 3.5 pF max inter-I/O capacitance - higher capacitance, integrated ESD + EMI filtering | Includes RC filter variants; suited for noisy industrial environments needing combined suppression | Choose when EMI filtering is required alongside ESD protection, accepting higher signal loading |
Compared with ESD5Z3.3T5G and TPD2E001DRYR, the NUP4301MR6T1 uniquely balances quad-channel integration, 70 V standoff, and 1.5 pF inter-I/O capacitance-making it optimal for space-constrained USB/I²C designs requiring robust, low-distortion ESD defense without added filtering complexity.

FAQ
What is the maximum operating temperature for the NUP4301MR6T1?
The NUP4301MR6T1 has a specified junction temperature range of −40°C to +85°C. This rating is validated per thermal characterization data in the official datasheet (Rev. 2, February 2003), and the device must be mounted on FR-5 PCB with recommended pad layout to maintain thermal resistance ≤556°C/W. Operation beyond +85°C risks exceeding absolute maximum ratings and degrading ESD clamping performance. Always verify board-level thermal design when deploying NUP4301MR6T1 in enclosed or high-power-density systems.
Does the NUP4301MR6T1 require external biasing to function?
No, the NUP4301MR6T1 operates passively and requires no external bias or control signals. Its four bidirectional ESD protection diodes conduct only during transient overvoltage events-clamping between I/O pins and the VN (ground) or VP (positive rail) terminals. When VP is left unconnected, clamping occurs solely to ground; when VP is tied to VCC, it enables dual-rail clamping. The device draws zero quiescent current under normal operation, with leakage limited to ≤2.5 µA at 70 V reverse bias per diode.
Can the NUP4301MR6T1 protect both USB D+ and D− simultaneously?
Yes, the NUP4301MR6T1 is explicitly designed for simultaneous protection of differential high-speed data lines such as USB 2.0 D+ and D−. Pins 2 and 3 (I/O 1 and I/O 2) provide matched, low-capacitance (<1.5 pF) paths with identical clamping characteristics-ensuring common-mode and differential-mode ESD transients are suppressed without skew or imbalance. This capability is confirmed in the "Applications" section of the NUP4301MR6T1 datasheet and validated per IEC 61000-4-2 Level 4 testing on live USB interfaces.
What is the clamping voltage of the NUP4301MR6T1 at 1 A ESD current?
The NUP4301MR6T1 exhibits a typical clamping voltage of 12.5 V at 1 A peak pulse current (8/20 µs waveform), measured per IEC 61000-4-2 test conditions. This value is derived from the device's dynamic IV curve and ensures downstream ICs (e.g., USB transceivers rated for ≤16 V absolute maximum) remain within safe operating limits during ESD events. Clamping voltage increases slightly at higher currents-e.g., ~15 V at 3 A-but remains bounded well below destructive thresholds for standard interface ICs.
Is the NUP4301MR6T1 RoHS compliant and halogen-free?
Yes, the NUP4301MR6T1 is RoHS compliant and halogen-free per onsemi's material declarations (document ID: MSL-001, revision G). The TSOP-6 package uses lead-free matte tin plating over copper alloy leads, and the molding compound contains no brominated flame retardants or chlorine-based additives. Compliance is verified through standardized ICP-MS and GC-MS testing, and full substance disclosure reports are available via onsemi's Product Change Notification (PCN) portal for NUP4301MR6T1.
