Product details
Overview
NUP4302MR6T1 from onsemi is a Schottky diode array designed for ESD protection of four high-speed data lines, featuring 30 V reverse breakdown voltage, ≤1.00 V forward voltage at 100 mA, 28 pF I/O-to-GND capacitance, 5.0 ns reverse recovery time, and IEC 61000-4-2 Level 4 compliance - deployed in USB 2.0 data line protection.
For engineers reviewing the NUP4302MR6T1 datasheet, pinout, applications, or equivalent options, key selection criteria include low-clamping-voltage ESD response, sub-1V forward drop for minimal signal distortion, TSOP-6 footprint compatibility, and Class 3B HBM rating for robust system-level transient immunity.
Technical Context
The NUP4302MR6T1 integrates four independent Schottky diodes with a common cathode tied to VCC (Pin 5) and grounded anodes (Pins 1, 3, 4, 6), enabling bidirectional clamping between data lines and power rail. Its PN junction guard ring structure enhances ESD robustness without compromising switching speed.
Designed specifically for high-frequency interfaces, it delivers 28 pF total capacitance at 0 V bias (I/O-to-GND) and 18 pF (I/O-to-I/O), supporting signal integrity in USB 2.0 (480 Mbps) and DVI applications. The 5.0 ns trr and 0.28–1.00 V VF range across 0.1–100 mA confirm suitability for low-voltage, fast-edge digital signaling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (HBM) | Class 3B (>16 kV) - withstands human-body discharges without latch-up or parametric shift |
| IEC 61000-4-2 Level | Level 4 (±15 kV air, ±8 kV contact) - meets industrial and consumer interface immunity standards |
| Reverse Breakdown Voltage | 30 V - clamps transients above system VCC while avoiding false triggering during normal operation |
| Forward Voltage (IF = 100 mA) | 1.00 V - minimizes voltage drop across protection path, preserving signal swing in 3.3 V/5 V buses |
| Total Capacitance (I/O–GND) | 28 pF @ 0 V, 1 MHz - maintains signal integrity up to ~1 GHz bandwidth in USB 2.0 differential pairs |
| Reverse Recovery Time | 5.0 ns - enables clean switching in high-speed data transitions without tail current distortion |
| Junction Temperature Range | −55 °C to +125 °C - supports operation in automotive infotainment and industrial display environments |

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, 12 pF typical capacitance, SOD-523 package | Requires four separate placements; lower capacitance but higher assembly cost and board space | Preferred when ultra-low capacitance (<15 pF) is mandatory and layout density is not constrained |
| TPD4E001DPVR | Quad-channel, 5.5 V VRWM, 3.5 pF per channel, 0.65 mm pitch USON-10 package | Lower capacitance and smaller footprint, but requires VCC-independent rail for internal clamp bias | Selected for next-gen USB-C or MIPI D-PHY interfaces where <5 pF/channel is required |
Compared with NUP4302MR6T1, ESZ5Z3.3T5G offers lower per-channel capacitance but increases BOM count and routing complexity, while TPD4E001DPVR achieves superior high-frequency performance at the cost of tighter layout constraints and different bias architecture.

FAQ
What is the primary function of the NUP4302MR6T1 in circuit protection?
The NUP4302MR6T1 functions as a quad-channel Schottky diode array for bidirectional ESD suppression on high-speed data lines. It clamps transient voltages between I/O pins and either GND or VCC using low-forward-voltage diodes. Its design ensures fast response to ESD events per IEC 61000-4-2 Level 4 while maintaining signal integrity - critical for reliable operation of the NUP4302MR6T1 in USB and DVI interfaces.
Is the NUP4302MR6T1 still in active production?
No, the NUP4302MR6T1 is officially discontinued per onsemi's November 2025 datasheet revision. However, Aetrix Electronics maintains legacy inventory and supports last-time buys with full traceability. Customers should consult obsolescence mitigation plans early, as the NUP4302MR6T1 has no direct pin-compatible replacement announced by onsemi.
How does the NUP4302MR6T1 achieve IEC 61000-4-2 Level 4 compliance?
The NUP4302MR6T1 achieves IEC 61000-4-2 Level 4 compliance through its integrated PN junction guard ring structure and optimized Schottky die layout, validated to withstand ±15 kV air discharge and ±8 kV contact discharge. This performance is confirmed in onsemi's characterization lab and documented in the NUP4302MR6T1 datasheet - not derived from family-level assumptions.
What is the role of Pin 5 (VCC) in the NUP4302MR6T1 configuration?
Pin 5 (VCC) serves as the common cathode connection for all four Schottky diodes inside the NUP4302MR6T1. It must be tied to the local I/O power rail to enable bidirectional clamping: during positive transients, current flows from I/O to VCC; during negative transients, current flows from I/O to GND (Pin 2). This architecture defines the operational behavior of the NUP4302MR6T1 in real-world layouts.
Can the NUP4302MR6T1 be used in USB 3.0 or higher-speed interfaces?
No, the NUP4302MR6T1 is not recommended for USB 3.0 (5 Gbps) or faster interfaces due to its 28 pF I/O-to-GND capacitance, which exceeds the typical <1.5 pF requirement for SuperSpeed differential pairs. Its electrical characteristics - including trr and CT - were characterized and specified only for USB 2.0 and DVI applications, as stated in the NUP4302MR6T1 datasheet.
