Product details
Overview
NSP4201MR6T1G from onsemi is a unidirectional ESD and surge protection diode array in TSOP-6 package, designed for high-speed data line protection with 5.0 V working voltage, ±30 kV IEC 61000−4−2 contact ESD rating, 14.0 V clamping voltage at 25 A (8/20 µs), and 1.5–3.0 pF I/O-to-I/O capacitance - deployed in USB 2.0 data lines and DVI interfaces.
For engineers reviewing the NSP4201MR6T1G datasheet, pinout, applications, or equivalent options, key selection criteria include low clamping voltage under lightning surge, sub-5 pF signal-line capacitance, AEC-Q101 qualification, and TSOP-6 footprint compatibility with high-density PCB layouts.
Technical Context
The NSP4201MR6T1G integrates five unidirectional TVS diodes in a single TSOP-6 package, each configured between an I/O pin and ground (pins 1, 3, 4, 6 → GND via pin 2), enabling simultaneous protection of four high-speed signal lines. Its low-leakage design (<1.0 µA at 5 V) preserves signal integrity in battery-powered and low-power systems.
Clamping behavior follows IEC 61000−4−5 compliance with 25 A (8/20 µs) surge handling and exhibits monotonic voltage rise from 9.0 V (1 A) to 14.0 V (25 A), ensuring predictable overvoltage limiting. Junction capacitance remains below 3.0 pF between I/O pins, supporting >480 Mbps USB 2.0 signaling without measurable signal degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 5.0 V - matches standard USB 2.0 and DVI power rail levels; ensures no conduction during normal operation. |
| Clamping Voltage (VC) | 14.0 V @ 25 A (8/20 µs) - limits transient overvoltage to safe levels for downstream 3.3 V/5 V logic ICs. |
| ESD Rating | ±30 kV contact per IEC 61000−4−2 - exceeds industrial and consumer immunity requirements. |
| Junction Capacitance | 1.5–3.0 pF (I/O-to-I/O) - enables full-speed USB 2.0 (480 Mbps) without signal rise-time degradation. |
| Leakage Current | ≤1.0 µA @ VRWM - minimizes standby power loss in portable and always-on interface designs. |
| Surge Current | 25 A (8/20 µs) per IEC 61000−4−5 - protects against induced lightning surges on external cables. |
| Operating Temp | −40 °C to +125 °C - supports automotive cabin and industrial ambient environments. |
Pinout & Package
NSP4201MR6T1G uses the TSOP-6 (Case 318G) package: 3.00 × 1.50 × 0.90 mm, 0.95 mm pitch, Pb-free, RoHS-compliant, with gull-wing leads suitable for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O Channel A | Protected signal line input/output; connected internally to cathode of unidirectional TVS diode to pin 2 (GND). |
| 2 | GND | Common ground reference for all five internal TVS diodes; must be low-inductance connection to system ground plane. |
| 3 | I/O Channel B | Second protected signal line; independent clamping path to pin 2, isolated from other I/O pins. |
| 4 | I/O Channel C | Third protected signal line; maintains <3.0 pF coupling to adjacent I/O pins for differential pair integrity. |
| 5 | VP (Power Rail) | Not connected internally (N/C); reserved for future variants; left floating or tied to GND per layout best practice. |
| 6 | I/O Channel D | Fourth protected signal line; identical electrical characteristics to pins 1/3/4; supports quad-line interface protection. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000−4−2 ±30 kV Contact ESD Protection | Enables robust immunity in handheld and docking station interfaces without external spark gaps or RC filters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD and surge protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1001-01WTG | Lower VRWM (3.3 V), higher capacitance (5.5 pF I/O–I/O), same TSOP-6 package. | Better suited for 3.3 V-only interfaces (e.g., PCIe lanes); less ideal for mixed 5 V/3.3 V USB 2.0 designs. | Select SP1001-01WTG only when system operates strictly at 3.3 V and higher capacitance is acceptable. |
| ESD5Z5.0T1G | Single-channel device (not array), identical VRWM (5.0 V) and clamping (14.0 V @ 25 A), SOD-523 package. | Requires four discrete placements for quad-line protection; increases PCB area and assembly cost vs. integrated NSP4201MR6T1G. | Choose ESD5Z5.0T1G only for legacy layouts lacking space for TSOP-6 or where channel isolation mandates discrete placement. |
Compared with SP1001-01WTG and ESD5Z5.0T1G, the NSP4201MR6T1G uniquely delivers quad-channel 5 V protection in one TSOP-6 footprint with sub-3 pF I/O–I/O capacitance - optimizing board space, signal fidelity, and AEC-Q101 compliance for high-speed automotive and consumer interfaces.

FAQ
What is the maximum clamping voltage of the NSP4201MR6T1G under a 25 A IEC 61000−4−5 surge?
The NSP4201MR6T1G clamps to 14.0 V when subjected to a 25 A (8/20 µs) lightning surge pulse per IEC 61000−4−5. This value is measured between any I/O pin and ground (pin 2) and ensures downstream 5 V-tolerant ICs remain within safe operating voltage limits during transient events. The NSP4201MR6T1G maintains this performance across its full −40 °C to +125 °C operating junction temperature range.
Does the NSP4201MR6T1G support bidirectional signal lines such as USB D+ and D−?
Yes - the NSP4201MR6T1G implements unidirectional TVS diodes from each I/O pin (1, 3, 4, 6) to ground (pin 2), making it fully compatible with bidirectional data lines like USB D+ and D−. Its 5.0 V VRWM aligns with USB 2.0 signal swing, and its low leakage (<1.0 µA) prevents DC bias disruption. The NSP4201MR6T1G does not conduct during normal signal transitions, preserving protocol integrity.
Is the NSP4201MR6T1G qualified for automotive applications?
Yes - the NSP4201MR6T1G is AEC-Q101 qualified and PPAP capable, with full test documentation per automotive stress standards. It operates reliably from −40 °C to +125 °C and meets UL 94 V−0 flammability requirements, making it suitable for infotainment displays, digital instrument clusters, and ADAS camera links. The NSP4201MR6T1G is also offered in an SZ-prefix variant (SZNSP4201MR6T1G) for enhanced automotive traceability.
What is the junction capacitance between I/O pins on the NSP4201MR6T1G?
The NSP4201MR6T1G exhibits 1.5–3.0 pF junction capacitance between I/O pins (e.g., pin 1 to pin 3) at 0 V reverse bias and 1 MHz frequency. This ultra-low inter-pin capacitance prevents crosstalk and preserves signal integrity in high-speed differential interfaces like USB 2.0 and DVI. Measured values are confirmed in the official onsemi datasheet under "ELECTRICAL CHARACTERISTICS" section.
Can pin 5 (VP) of the NSP4201MR6T1G be used as a power supply connection?
No - pin 5 (VP) is not internally connected in the NSP4201MR6T1G and serves no functional role. It is a no-connect (N/C) terminal per the official onsemi datasheet and mechanical drawings. Leaving pin 5 floating is acceptable; tying it to ground may reduce parasitic antenna effects but provides no electrical benefit. The NSP4201MR6T1G derives no power and requires no external supply - all protection functions are passive.
